these products.
Water temperature in excess of 100° F (37.7° C) may be hazardous to your
health. Prolonged immersion in hot water may induce hyperthermia.
Hyperthermia occurs when the internal temperature of the body reaches a
level several degrees above normal body temperature of 98.6° F (37° C.).
Effects of hyperthermia include: (1) Unawareness of impending danger. (2)
Failure to perceive heat. (3) Failure to recognize the need to leave the spa. (4)
Physical inability to exit the spa. (5) Fetal damage in pregnant women. (6)
Unconsciousness resulting in danger of drowning. The use of alcohol, drugs, or
medication can greatly increase the risk of fatal hyperthermia in hot tubs and
spas.
Maximum working water temperature for this filter is 95° F (35°C).
When setting up pool water turnovers or flow rates the operator must
consider local codes governing turnover as well as disinfectant feed ratios.
DO NOT increase pump size; this may increase the flow rate through the
system and exceed the maximum flow rate stated on the drain cover.
If this pump and sand filter is intended for use in other than single-family
dwellings, a clearly labeled emergency switch shall be provided as part of the
installation. The switch shall be readily accessible to the occupants and shall
be installed at least 5 feet (1.52 m) away, adjacent to, and within sight of, this
pump and sand filter system.
IMPORTANT NOTICE - Attention Installer: This Installation and User’s Guide
(“Guide”) contains important information about the installation, operation and safe
use of this pump and sand filter. This Guide should be given to the owner and/or
operator of this equipment.
This pump and sand filter system is intended for use in swimming
pool applications.
WARNINGS AND IMPORTANT SAFETY PRECAUTIONS
To reduce the risk of injury, do not permit children to use or operate this
pump and sand filter.
Pump and Sand Filter System Installation and User’s Guide
A pool or spa pump must be installed by a qualified pool and spa
service professional in accordance with the National Electrical Code and
all applicable local codes and ordinances. Improper installation may create an electrical hazard
which could result in death or serious injury to pool users, installers, or others due to
electrical shock, and may also cause damage to property.
ii
High Pressure from the sand filter can cause severe injury or
major property damage due to tank separation.
Release all pressure and read instructions before working on
the sand filter. If the filter clamp is adjusted under pressure,
the tank can separate, causing serious injury or major
property damage.
Pumps improperly sized or installed or used in applications other
than for which the pump was intended can result in serious personal
injury or death. These risks may include but not be limited to electric shock, fire, flooding,
suction entrapment or serious injury or property damage caused by a structural failure of
the pump or other system component.
Never exceed the maximum stated pump flow rating.
Only use a pumping system rated for the corresponding flow. FAILURE TO DO
SO CAN RESULT IN HAIR OR BODY ENTRAPMENT WHICH CAN CAUSE
SERIOUS PERSONAL INJURY OR DEATH. If in doubt about the rating of your
system, consult a qualified pool service professional.
Pumps are not a substitute for properly installed and secured pool
drain covers. An ANSI/ASME A112.19.8 approved anti-
entrapment drain cover must be used for each drain. Pools and spas should utilize a
minimum of two drains per pump. Regularly inspect all covers for cracks, damage
and advanced weathering. If a cover becomes loose, cracked, damaged, broken
or is missing, close the pool or spa immediately, shut off the pump, post a notice
and keep the pool or spa closed until an appropriate VGB 2008 certified cover is
properly installed. Covers deteriorate over time due to exposure to sunlight and
pool chemicals. This cover must be replaced within seven (7) years from
installation (or earlier if the cover becomes damaged in any way).
BEFORE WORKING ON FILTER!
(1) Stop pump.
(2) Open air release valve.
(3) Release all pressure from system.
PUMPS REQUIRE HIGH VOLTAGE WHICH CAN SHOCK, BURN,
OR CAUSE DEATH.
BEFORE WORKING ON PUMP!
Always disconnect power to the pool pump at the circuit
breaker before servicing the pump. Failure to do so could
result in death or serious injury to service person, pool
users or others due to electric shock.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION:
WARNINGS AND IMPORTANT SAFETY PRECAUTIONS
Pump and Sand Filter System Installation and User’s Guide
F
Hair Entanglement – When the hair tangles or knots in the drain cover,
trapping the swimmer underwater. This hazard is present when the flow
rating of the cover is too small for the pump or pumps.
Limb Entrapment – When a limb is sucked or inserted into an opening
resulting in a mechanical bind or swelling. This hazard is present when a
drain cover is missing, broken, loose, cracked or not properly secured.
Body Entrapment – When a portion of the body is held against the drain cover
trapping the swimmer underwater. This hazard is present when the drain cover
is missing, broken or the cover flow rating is not high enough for the pump or
pumps.
Evisceration/Disembowelment – When a person sits on an open pool
(particularly a child wading pool) or spa outlet and suction is applied directly to
the intestines, causing severe intestinal damage. This hazard is present when
the drain cover is missing, loose, cracked, or not properly secured.
Mechanical Entrapment – When jewelry, swimsuit, hair decorations, finger, toe
or knuckle is caught in an opening of an outlet or drain cover. This hazard is
present when the drain cover is missing, broken, loose, cracked, or not prop-
erly secured.
SUCTION ENTRAPMENT HAZARD
Pool and spa pumps move large volumes of water, which can pose extreme
danger if a person’s hair comes in close proximity to a drain that is not the proper
size for the pump or pumps.

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS
Pump and Sand Filter System Installation and User’s Guide
Section 1
Pump and Sand Filter System Overview
This system operates under pressure and if assembled improperly or operated
with air in the water circulation system it can separate and result in an
accident causing serious bodily injury. A warning label has been affixed to the
filter and should not be removed. Keep safety labels in good condition and
replace if missing or illegible. (For free labels call, (919)-774-4151). Pumps
and filters should never be tested or subjected to air or gas under pressure.
All gases are compressible and under pressure create a danger. Serious
bodily injury or property damage could occur if the pump or filter is subjected
to air or gas pressure.
The system consists primarily of a centrifugal pump, a high rate sand filter
with control valve, a connecting hose and a mounting base. Your centrifugal
pump is driven by an electric motor. The motor is directly attached to the
pump impeller. As the electric motor turns it causes the impeller to turn and
this causes the water to flow. The water flows into the hair and lint pot inlet
and through the basket assembly to prestrain large particles. The flow then
enters the center of the pump housing. The flow goes through the impeller
into the stationary diffuser, out the pump discharge port, through the
connecting hose and into the filter control valve. Dirt is collected in the filter
as the water flows through the control valve at the top of the filter and is
directed downward onto the top surface of the filter sand bed. The dirt is
collected in the sand bed and the clean water flows through the lower piping
at the bottom of the filter up through the center pipe into the control valve at
the top of the filter. Clean water then returns through the piping system to the
pool. The pressure will rise and the flow to the pool will be lowered as the dirt
is collected in the filter. Eventually, the filter will become so plugged with dirt
that it will be necessary to perform the backwash procedure. It is important to
know when to backwash the filter. For backwashing information, see page 12
and 13. The six (6) operating position and one (1) “Winterize” position valve is
designed to provide all the necessary positions required to operate, maintain,
troubleshoot and service your sand filter.
1
Air entering the filter and a valve clamp not closed
properly can cause the valve to separate and could
cause serious bodily injury and/or property damage.
To prevent equipment damage and possible injury,
always turn pump off before changing valve position.
Pump and Sand Filter System Installation and User’s Guide
Valve Position and Water Flow Directions
FILTER: From pump, through valve, downward through filter sand bed, up
through center pipe to valve return port, and back to the pool for normal filter
action and vacuuming pool through filter.
BACKWASH: From pump, through valve, down through center pipe, up
through filter sand to valve, and out wasteport. This position is used for
cleaning filter by reversing flow.
RINSE: From pump, through valve, downward through filter sand, up through
center pipe to valve and out waste port. This position is used for start up
cleaning and resettling filter bed after backwashing.
WASTE: From pump, through valve, bypasses filter and goes to wasteport.
This position is for vacuuming directly to waste, lowering pool level, or
draining pool.
CLOSED: NO FLOW IN THIS POSITION - DO NOT USE THIS
SETTING WITH PUMP OPERATING.
RECIRCULATING: From pump, through valve, bypass filter and goes to
return port and back to pool. This position is for circulating water without
going through filter.
This filter operates under high pressure. When any part of the circulating
system (e.g., clamp, pump, filter, valves, etc.) is serviced, air can enter the
system and become pressurized. Pressurized air can cause the lid or control
valve to separate which may result in serious injury, death, or property
damage. To avoid this potential hazard, follow these instructions.
1. Before repositioning valves and before beginning the assembly,
disassembly, or adjustment of the clamp or any other service of the
circulating system:
(a) Turn the pump off and shut off any automatic controls to ensure the system
is not inadvertently started during the servicing;
(b) Open manual air relief valve;
(c) Wait until all pressure is relieved, pressure gauge must read zero (0).
2. Whenever installing the filter clamp, follow the filter valve and clamp
installation instructions exactly.
3. Once service on the circulating system is complete, follow system restart
instructions exactly.
4. Maintain circulation system properly. Replace worn or damaged parts
immediately (e.g., clamp, pressure gauge, relief valve, o-rings, etc.).
5. Be sure that the filter is properly mounted and positioned according to
instructions provided.

Failure to operate your filter system or
inadequate filtration can cause poor
water clarity obstructing visibility in your pool and can allow
diving into or on top of obscured objects, which can cause
serious personal injury or drowning.
WINTERIZING: Valve position for a winterized sand filter, see page 16.
Please note that a sand filter removes suspended matter and does not sanitize
the pool. The pool water must be sanitized and the water must be balanced
for sparkling clear water. Pool chemistry is a specialized area and you
should consult your local pool service specialist for specific details. In
general proper pool sanitation requires a free chlorine level of 1 to 2 PPM
and a pH range of 7.2 to 7.6.
Your filtration system should be designed to meet your local health codes. As
a minimum, you must be sure that your system will turnover the total volume
of water in your pool at least twice in a twenty-four (24) hour period.
Section 2
Installation
1. Read and understand all instructions before attempting to install,
operate, or maintain your pump and sand filter system.
2. Provide space and lighting for routine maintenance access. Locate the
system close to the pool. See Figure 1 for typical installation.
Note: Install electrical controls (e.g., on/off switches, timers, control
systems, etc.) at least five (5) feet from the filter. This will allow you
enough room to stand clear of the filter during system start up.
Systems that are unassembled should be assembled at this point. See
special instructions A through G.
A. Make sure all electrical breakers and switches to the pump are
switched off, and disconnect the communication cable from the pump
before installing the base.
B. Remove all individual components from carton and inspect for any
visible damage. If carton or parts are damaged contact seller or
freight company.
C. Place the system support base on the ground close to the final location
of the unit. See Figure 1 on the next page.

D. Examine the bottom of the lter and conrm the orientation of the
small mounting protrusions on the tank.
E. Align the protrusions on the tank with the corresponding recesses in
the lter support portion of the base and place the lter on the base.
This filter operates under pressure. With the valve
clamped properly and operated without air in the
system, this filter will operate in a safe manner. Air
entering the filter and the valve not clamped
correctly can cause the valve to separate, which
could cause serious personal injury and/or property
damage.
Always turn pump off before changing valve
positions. Changing valve positions while the pump
is running can damage the control valve, which
may cause serious injury or property damage.

4. Be certain to install the precise amount of filter sand listed on your
filter nameplate. You must use only No. 20 standard silica sand
having a uniformity coefficient of 1.75 or less. No. 20 silica sand has
a particle size of .018-.022 inches (.45 to .55mm). Before pouring the
sand into the filter, look inside and check the lower under drain for
broken or loose laterals (or fingers), which may have been
accidentally damaged by rough handling during shipment. Replace any
parts as necessary.
Figure 5.
5. Install the sand guide in the top of the filter and fill the tank about half
full of water. Pour the sand into the top of the filter at a slow rate so
that the weight of the sand does not damage the laterals. After the
required amount of sand has been installed, remove and discard the
sand guide. Wash away all sand around the opening at the top of the
tank.
3. Now, move the system to its final position. The system must be placed
on level solid earth. The entire system filled with sand and water can
weigh several hundred pounds.

Begin to tighten the clamp screws with a Phillips screwdriver. Tap around
the outside of the clamp with a rubber mallet (or similar tool) to ensure
uniform loading and proper seating of the clamp halves. Continue
tapping and tightening until the clamp ends touch each other. Do not
tighten beyond this point to avoid damaging the screws or clamp.
High Pressure:
Improper tank valve assembly could cause the valve
to separate and cause serious in jury and/or major
property damage.
6. Be sure top of lter is free of any sand or debris and valve o-ring is in
place on valve body. Install valve so that the port locations are in the
desired nal position. See Figure 1 (see page 4).
7. Be sure that the valve is rmly pushed into the top of the tank and that
the ange of the tank and the ange of the valve are contacting each
other. See Figure 6.

10. Valve ports are labeled with the location of where they should be
connected i.e. pump port must go to pump discharge, waste port must
go to waste line, and return port must go to the pool return.
11. The filter unit has a maximum operating pressure listed on the filter
nameplate. DO NOT OPERATE this unit above the maximum
operating pressure of the valve or the filter. Never connect the filter
and valve unit to a pump which can generate a pressure that exceeds
the operating pressure of the filter or valve.
12. Use sealant on all tapered male connections of pipes and fittings. Use
only sealant compounds suited for plastic pipe. Support pipe to prevent
strains on filter, pump, or valve. DO NOT USE PETROLEUM
BASE PRODUCTS. NOTICE: All valve internal threads are
tapered except the air bleeder connection. Do not over tighten
tapered threaded connection.
13. Install pressure gauge in ¼” NPT port directly across from the pump
port of the valve.
14. Never store pool chemicals within 10 feet of your pool filter, pump, or
valve. Pool chemicals should be stored in a cool, dry, well ventilated
area.
Chemical fumes and/or spills can cause serious
corrosion to the filter and pump structural components. Structurally
weakened components can cause filter, pump or valve attachments to
separate and could cause serious bodily injury or property damage.
The system’s centrifugal pump operates with electrical
voltage, and can generate both vacuum and pressure in the water
system. When properly wired and plumbed, this pump will operate in a
safe manner.
High voltage can cause serious or fatal injury. Always
install a suitable GFCI at the power source of this unit as an added
safety precaution. Article 681-31 of the NEC requires that a GFCI be
used if this pump is used with a storable pool.
15. Avoid over tightening the pipe threads when connecting fittings to the
pump or valve. Proper procedure is to apply a pipe sealant to the
thread and then install hand tight plus one (1) turn. DO NOT OVER
TIGHTEN.
16. The pump suction line should not be smaller than the pipe on the inlet
of the pump.
17. Electrical connection of the pump should be performed by a
qualified pool and spa service professional in accordance with
the National Electrical Code or your local electrical code.

18. Use lug on top of motor frame to bond together motor and all metallic
parts of pool, spa, or hot tub structure and all electrical equipment,
metal conduit, and metal piping with a solid copper conductor not less
than No. 8 A.W.G.
19. The pump motor must be wired for the proper voltage in accordance
with the wiring diagram supplied with the motor. Note: Wiring the
motor with the incorrect supply voltage will cause damage to the
motor and void warranty.
20. The wiring to the motor should be kept as short as possible and large
enough NOT to cause excessive voltage drop which could damage
your pump. Use the chart above as a guide to ensure adequate voltage
is supplied to the pump.
21. The product may be furnished with a 6 ft. three (3) prong test
cord. The cord is provided for your convenience to allow you to
check the pump operation before installing the system on the
pool. The test cord should NOT be used for permanent
connection. When checking the pump operation, do not run the pump
longer than 30 seconds. Damage to the pump’s mechanical seal could
result if ran longer than 30 seconds.
Blockage of suction fittings can cause serious or fatal injury
due to drowning. To reduce the risk of injury, do not permit
children to operate this product.
Never work on the pump while it is running or power is still
connected. High voltage can cause serious or fatal injury. A
suitable ground fault interrupter should always be installed
at the power supply source of this unit. Be sure to ground
the motor before connecting to electrical AC power supply.
Failure to ground the motor can cause serious or fatal
electrical shock hazard. DO NOT ground to a gas supply
pipe line.

FOR CORD AND PLUG-CONNECTED UNITS
RISK OF ELECTRICAL SHOCK:
Do Not Bury Cord. Locate cord to minimize abuse from lawn
mowers, hedge trimmers, and other equipment.
To reduce the risk of electrical shock, replace damaged cord
immediately.
To reduce the risk of electrical shock, Do Not Use an
extension cord to connect unit to electrical supply; provide a
properly located outlet.
This filter operates under pressure. With the valve
clamped properly and operated without air in the
system, this filter will operate in a safe manner. Air
entering the filter and the valve not clamped
correctly can cause the valve to separate, which
could cause serious personal injury and/or property
damage.
Always turn pump off before changing valve
positions. Changing valve positions while the pump
is running can damage the control valve, which may
cause serious injury or property damage.
1. Clean a new pool before filling it with water. Excessive dirt and large
particles can cause damage to the pump and sand filter system.
2. Verify the backwash line is open so that water is free to come from
the pool and flow out the backwash line. Set the valve in “Backwash”
position.
Connect only to a ground type receptacle
protected by a Ground Fault Circuit Inter-
rupter (GFCI). Contact a qualified electrician
if you cannot verify that the receptacle is
protected by GFCI.
Pump and Sand Filter System Installation and User’s Guide

3. Make sure the pump pot is full with water before starting the pump.
Keep all air vents on underside of motor (or motor enclosure) free of
debris to ensure proper cooling of motor.
4. Check valve clamp on filter for proper assembly. Note: See
instructions under “Installation” section of this manual if in doubt.
5. Open manual air bleeder on filter. STAND CLEAR OF FILTER and
start the pump, allowing it time to prime.
Note: Install electrical controls (e.g., on/off switches, timers, control
systems, etc.) at least five (5) feet from the filter. This will allow you
enough room to stand clear of the filter during system start up.
6. Close the air bleeder on the filter when a steady stream of water
emerges.
Note: Pool Filter Sand is typically prewashed and should not
require extensive backwashing. However, the shipping process
may cause excessive abrasion which could require an extended
backwash cycle at initial start-up; continue to backwash for
three (3) minutes.
7. Stop the pump. Set the valve to the “Filter” position.
8. Ensure all suction and pool return lines are open so that water is free
to come from the pool and return to the pool.
9. Open the manual air bleeder on the filter. STAND CLEAR OF THE
FILTER and start the pump.
10. Close the air bleeder on the filter when a steady stream of water
emerges.
11. The filter has now started its filtering cycle. Be sure the water is
returning to the pool and take note of the operating pressure when the
filter is clean.
To prevent equipment damage and possible injury,
always switch pump off before changing valve position.
Maintenance
Proper care and maintenance of the pump and sand filter system will add
many years of enjoyment to the pool. Follow these suggestions for long
trouble free operation.
Pump and Sand Filter System Installation and User’s Guide
1. To clean the exterior of the pump and sand filter system of dust and
dirt, wash with a mild detergent and water and then hose off. Do not
use solvents.
2. If internal filter maintenance is required, sand may be removed by
removing the entire drain spigot from the bottom of the filter and
flushing with a garden hose.
3. The filter is a pressure vessel and should never be serviced while under
pressure. Always relieve tank pressure and open air bleeder on filter
before attempting to service the filter.
4. When restarting the filter always open the manual air bleeder on the
filter and STAND CLEAR OF FILTER.
5. The strainer basket in the pump should be inspected and cleaned twice
each week. Remove the clear lid and the basket, and clean debris from
basket. Inspect the lid o-ring; if damaged, replace. The pump seal
requires no lubrication. The pump motor should only be serviced by a
motor service center.
12
Cleaning
1. The filter on a new pool should be backwashed, and cleaned after the
first 48 hours of operation to clean out construction debris. There are
three different ways to identify when the filter needs backwashing:
a) The most accurate indicator on pool systems with a flow meter is to
backwash when the flow decreases 30% from original (clean filter)
flow. For example, if the original flow was 60 GPM, the filter should
be backwashed when the flow is reduced by about 20 GPM (or 30%)
to 40 GPM.
b) A more subjective and less accurate indicator is to observe the
amount of water flowing from the flow directionals located in the wall
of the pool. The filter should be backwashed once it is detected that
the flow has been reduced.
c) The most commonly used but least accurate indicator is to
backwash when the filter gauge reading increases 10 psi over the
initial (clean filter) reading.
2. It is important not to backwash the filter solely on a timed basis such
as every three days. It is also important to note that backwashing too
frequently actually causes poor filtration. Factors like weather
conditions, heavy rains, dust or pollen, and water temperatures all
affect the frequency of backwash. As you use your pool, you will
become aware of these influences.
Pump and Sand Filter System Installation and User’s Guide
Filter Backwash Procedure
1. Stop pump.
2. Be sure the suction and backwash lines are open so that water is free
to come from the pool and flow out the backwash line. Set control
valve to “Backwash” position.
3. STAND CLEAR OF FILTER and start pump.
4. Backwash filter for approximately three (3) minutes or until backwash
water is clean.
5. Stop pump and set valve to “Rinse” position.
6. STAND CLEAR OF FILTER and start pump.
7. Rinse the filter for approximately 30 seconds.
8. Stop pump and set valve to “Filter” position.
9. Be sure the pool return line is open so that water may flow freely from
the filter back to the pool.
10. Open manual air bleeder on filter. STAND CLEAR OF FILTER and
start pump.
11. Close manual air bleeder on filter when a steady stream of water
emerges from the bleeder.
12. The filter has now started its filtering cycle. Be sure the water is
returning to the pool and take note of the filter pressure.
13. The filter pressure in Step 12 above should not exceed the pressure
originally observed on the filter when it was initially started. If after
backwashing, the pressure is 4 to 6 psi above the start condition it will
be necessary to chemically clean the sand bed.

To prevent equipment damage and possible injury,
always switch pump off before changing valve position.

appropriate valves to prevent draining the pool.
5. Switch off pump, open filter drain and allow filter to empty. Place valve
in “Backwash” position.
6. After filter has drained, close filter drain and remove the pump strainer
pot lid.
7. Be sure the backwash lines are open.
8. Switch the pump on and slowly pour the cleaning solution into the pump
strainer with the pump running. If filter is below pool, open shut off
valve slightly to allow pump to run.
9. Continue adding solution until the sand bed is saturated with cleaning
solution.
10. Switch off the pump and leave filter in “Backwash” position. Allow the
filter to stand overnight (12 hours).
11. Replace the pump lid and follow backwash procedure as described
above.
