SECTION 1: MOUNTING THE STEAM GENERATOR
DIAGRAM 1 DIAGRAM 2
The AMEREC steam generator can be hung on a wall or sit on its base. The best mounting location will satisfy all or most of the
following:
WARNING: The generator will not operate properly, unless it is mounted level with the arrows pointed up
1. The generator should be installed in a dry, well ventilated area. Suggested locations are under a vanity, in a closet,
attic, crawl space or basement. Do not mount outdoors.
2. If the generator will be in an area difficult to access, the water supply should be equipped with easily access water shut-off
valve in case of emergency.
3. If the steam line is in an area where the temperature will be below 39°F (4°C) best results can be obtained by insulating the
steam pipe. Do Not mount the generator in an area subject to freezing.
4. The generator must be mounted in a minimum 7 cubic feet (0,2 cubic meter) space.
5. The location must allow access for service! Provide clearance for plumbing and electrical service and for element
removal. See Diagram 1.
6. The steam line should slope to allow condensation to drain. The mounting location should minimize the number of bends
and elbows in the steam line
7. The mounting location should allow for a drain hook up.
8. The steam line should be less than 20ft (6 m) long; 3ft (1 m) is preferred. Steam lines over 20ft (6 m) long should be
insulated.
WARNING
There must be no dips or valleys in the steam line.
Install the steam head so as to avoid potential user direct contact with the steam or where condensation may drip on the
user as this may present a scald hazard.
Do Not install any valves or other shut-off devices in the steam line!
Do Not interconnect steam lines! A separate steam line is required for each generator!
Do Not connect the drain line to the steam line or allow the drain empty into the steam room!

SECTION 1: MOUNTING THE STEAM GENERATOR (continued)
1. WALL MOUNTING: Remove the side cover. Note the location of the
mounting holes on the back of the generator. The screws must set directly into
studs or equivalent supports. Drill pilot holes on 14-1/2” (368 mm) centers and
install the two #10 1½" screws, provided.
See at right.
a) Carefully hang the generator on the two screws. Tighten the screws.
b) The generator may be further secured with two screws mounted on the
same 14-1/2” (368 mm) centers as shown.
c) Replace the front cover with its four screws.
2. FLOOR MOUNTING:
a) In general, the width of the unit allows it to sit on a shelf, across the ceiling
joists or on a floor. The generator must be restrained from moving.
Normally, the piping will provide adequate support. If not, additional
support must be provided.
b) All floor installed generators must provide for routine draining of the tank
and for draining the safety valve’s outlet.
SECTION 2: WATER QUALITY REQUIREMENTS
The nature of a boiler or steam bath generator requires testing of the feedwater
to avoid potential high concentrations of impurities which can cause a deposit
or scale to form on the internal surfaces. This deposit or scale can interfere with
the equipment's proper operation and even cause premature boiler or generator
failure. Concentration of impurities is generally controlled by treating the
feedwater and or "blowing down" the generator or boiler when it is not heating.
The "blow down" process
involves removing a portion of the tank water with high solid concentration and
replacing it with makeup water.
This is particularly important in areas with high calcium levels and other water
quality problems. Calcium build-up can cause poor steamer performance and damage the heating elements!
Be especially careful to prevent foaming in the steamer’s water! Foaming water will affect the water level measuring
systems in steamers and boilers, causing operation problems and possibly leading to early element failures!
To insure proper operation, the water supply should be tested prior to operating the equipment. There are several treatment
processes which can be used if you have a problem with hard water. A local reliable water treatment company can recommend
the appropriate treatment if required. The recommended feedwater quality is listed on the next page.
Recommended Feedwater Quality
Hardness 10 – 30 ppm - (0.5 - 1.75 gpg)
T-Alkalinity 150 – 700 ppm - (8.75 - 40.8 gpg)
Silica Range 15 – 25 ppm - (1.28 - 1.45 gpg)
PH (strength of alkalinity) 10.5 -- 11.5
IMPORTANT!
Regular maintenance will help your steamer work properly for a long time. Check for leaks,
loose or damaged wires, signs of corrosion and calcium build up in the tank on the level probe.

1. INSTALL WATER LINE Connect a cold water line to the generators water valve. The valve input is 3/8” NPT. A shut-off valve
should be placed in the line for each generator to allow easier servicing later, if needed, and for emergency shut-off. Make sure
the shut-off is open, providing water to the generator before first turning the on.
IMPORTANT
Water pressure required: 20-100 psi (138-690 kPa)
If the generator is mounted in a place difficult for the home owner to access, the water supply
shut-off valve should be located where it can be quickly accessed in an emergency.
Do not use a saddle valve or saddle fitting for the water shut-off valve.
Flush water supply line before final hookup.
2. INSTALL STEAM LINE
a) At the generator: Install a 1/2" male NPT sweat adapter directly into the tank. Install a 1/2" union in the steam line to allow

SECTION 3: PLUMBING INSTRUCTIONS (continued)
b) Run the 1/2" copper steam line from the generator to the steam room. Refer to SECTION 1: MOUNTING THE STEAM
GENERATOR and Diagrams 3a and 3b.
The steam line must slope to allow condensation to drain into the tank or room.
There must be no dips in the steam line. Low areas may collect condensation and cause faulty operation or cause hot
water to spit into the room.
c) The steam line should enter the steam room 18” (460 mm) above the floor or at least 12” (305 mm) above a tub rim or
ledge. The steam line outlet should be at least 6” (150 mm) from other steam heads to either side and 12” (305 mm) from
walls or other surfaces to either side. See Diagrams 4, 5 and 6.
Note: See Diagram 6 for a typical installation. Additional steam heads may be
added to any installation to reduce steam noise or to provide more steam
dispersion around a large room
Note: if steam vents are too close to other surfaces, the steam may be cooled
and the surfaces damaged.
d) At the steam room: Drill/prepare a 1-3/8” (35 mm) hole for the steam line
entry. Center the 1/2" copper steam pipe in the hole. See Diagram 4.
Terminate the steam line with a 1/2" NPT male adapter.
Stub the line out into the room 3/8” (9,5 mm) from the finished surface.
Secure the steam line to a structural member.
3. INSTALL STEAM HEAD INSULATOR: Fill in gap (using 100% Silicone
caulk between steam pipe and finished wall surface at point of entry (see
Diagram 4). Apply silicone caulk to the finished wall side of the steam head
insulator (see Diagram 5) and screw on hand tight until it is flush with the wall
with the opening pointing down. If a hand tight fit does not align with the
opening pointing down, use Teflon tape on the steam line threads to adjust fit.
4. INSTALL STEAM HEAD: Slide the steam head on until it rests firmly against
the finished wall. Tighten the hex head screw underneath the steam head to
secure it in place with the Allen wrench provided. The steam head should be
level with its fragrance reservoir at the top. See Diagrams 4 and 6.
IMPORTANT
All fixture holes must be sealed with 100% silicon caulk to avoid moisture
damage within walls. Check all of the standard fixtures in the steam room.

SECTION 3: PLUMBING INSTRUCTIONS (continued)
5. INSTALL PRESSURE RELIEF SAFETY VALVE: Install the pressure relief valve into its port on the generator. Install the
safety valve within 6” (150) mm of the generator. Run a 3/4" copper line from the valve to a gravity flow drain. The pressure relief
valve outlet must drain in accordance with local and national codes.
AUTODRAIN All generators must have a drain valve installed to allow draining the tank for cleaning and maintenance. A
manual ball valve is supplied. An electronic ball valve is available in the ADK Autodrain option. When installed, Autodrain
automatically rinses and empties the steam tank approximately 25 minutes after a steam bath stops. This cleans the tank to
reduce problems caused by poor water quality and ensures every steam bath starts with clean, fresh water. Contact Amerec
Technical Support for more information. [email protected] or 1-425-951-1120 or at 1-800-363-0251
INSTALL DRAIN VALVE: Install 3/4" NPT pipe nipple directly into the
tank as shown in Diagram 7. Install a 3/4" ball valve or an Autodrain on
the nipple then add another nipple to the outlet of the valve. Add a union
to the outlet nipple to allow easy disconnection during servicing. Run a
3/4" copper line from the union to a gravity flow drain. The drain must be
connected in accordance with local and national codes.
IMPORTANT
All drain lines must run downhill, away from the steam generator! Also
see Diagram 3
Do not run the drain uphill.
Do not drain the safety valve into the steam line!
Do not drain the safety valve into the steam room! Draining the
tank into the steam room may present a scald hazard or
damage the materials used to construct the steam room.
Do not drain into the steam room!
SECTION 4: WIRING INSTRUCTIONS
ALSO SEE ELECTRICAL INFORMATION CHART AND WIRING DIAGRAMS
1. ELECTRICAL ROUGH-IN: Size wire for the generator as required by local or national codes. See the electrical information
on page13 for further information. Use copper wire only. Leave 4 ft (1,2 m) of slack wire at generator location for finish hookup.
Connect the generator to a dedicated circuit breaker. A GFI device is usually not required by safety agencies. One may be
installed if required by local codes or the owner. A GFI device will tend to nuisance trip due to heater element aging.
a. Route the copper supply wire with appropriate strain relief through the hole marked POWER ENTRY.
b. Connect the supply wires to the power terminal block as indicated on the wire diagram for your voltage and phase. This
may require moving factory installed jumper. Do not change the steamer’s internal jumpers or wiring. Only the supply wiring
side of the terminal blocks require configuration by the installer.
c. Connect the Earth wire to the copper Earth ground lug.
d. Cover the supply wires inside the steamer with a protective mesh or similar material to protect them from water valve
heating.
2. ELECTRICAL INFORMATION The AK steamers are available in 2 basic versions, one for 208V (intended for 208VAC
single and three phase for North American use) and the other for 240V (intended for all other installations. The 240V
models are rated at 240VAC but may be used on 208 to 240V single phase Line-to-Line or 208 to 240V~N (Line-to-Neutral)
or 208V to 240V three phase Delta without Neutral or for Y-connected three phase 380 to 415V~N3.
All Units are factory wired for single phase installation. The installer may change the input to three phase or three phase
with Neutral during initial installation (see the wiring diagrams on page 19-20).
The National Electrical Code (NEC) limits a steamer’s current to 48 Amps so, two separate power supplies ciruits are
required for the AK11 208V single phase.

SECTION 5: R30K BATH CONTROL
The R30K low voltage control can be mounted directly to a finished wall either inside or outside the steam room. The R30K does
not control the temperature in the steam room.
Use a 1-1/2” (36 mm) hole saw to drill a hole in the finished steam room wall where
the control is to be mounted (the control cable should already be roughed-in to this
location). See Diagram 13
Locate the control cable, pull it out through the mounting hole and plug it into the
connector on the back of the control board,, inside the housing.
Run a bead of 100% silicone caulk around the perimeter on the back of the control
housing. See Diagram 12. Insert the control into the wall cavity. See Diagram 13.
Connect the R30K control's cable to the steamer and plug it in to the S30B jack (top edge of the circuit board next to the S30A
terminal block).
DIAGRAM 13
SECTION 6: INITIAL START
1. Assure power and water are on. Press the control’s ON/OFF switch. The control should light then the water valve should turn
on to fill the steamer. While filling, check for leaks.
2. After the tank has filled to a safe level, the heating elements will turn on. Allow about 10 minutes for the steam to appear in
the steam room.
3. Once the steam is visible, use the control to turn the bath off. The steam should stop within a couple minutes and the water
valve should turn off. The control should not be lit.
4. Press the ON/OFF switch again. The control should light.
5. Within one minute the unit should again produce steam. It should call for water once every two minutes or more depending on
its power rating. It’s normal for the flow of steam out the steam head to slow for up to 10 seconds each time the unit calls for
water.
6. The steam bath will halt automatically in 30 minutes. When the time runs out the steam will stop and there should not be any
water flow. The control should not be lit.

SECTION 7. SERVICE
1. DESCRIPTION OF STEAM GENERATOR
The Printed Circuit Assembly (the “PCA”) provides the basic functions necessary to produce steam. The PCA controls makeup
water, provides a water level permissive for powering the elements and provides raw DC power for the system.
The PCA also provides regulated non-interruptible 12 VDC power for the generator control, and 5 VDC for the control, and a
built in bath timer.
2. MAINTENANCE OF STEAM GENERATORS
VISUAL INSPECTION - Whenever the generator is opened, inspect for any evidence of water leaks. Inspect the wiring for
any evidence of overheating. Check all electrical connections for tightness.
FLUSH TANK - Flush monthly, or more often, depending usage and on local water conditions.
FLUSHING PROCEDURE: with manual drain
1. The generator should be cool.
2. Press the ON/OFF button to turn the steamer on. The control should light.
3. Open the manual drain valve.
4. The unit will drain. Allow the water to run for a full 10 minutes, then press the ON/OFF button.
5. Allow the unit to drain completely. When the water stops, close the drain valve.
FLUSHING PROCEDURE: with Autodrain
1. The generator should be cool.
2. Press the ON/OFF button to turn the steamer on. The control should light.
3. Open the manual drain valve (if installed) and manually open the Autodrain valve by moving its lever until it latches.
4. The unit will drain without heating the water. Allow the water to run for a full 10 minutes, then press the ON/OFF button.
The control light should turn off.
5. Allow the unit to drain completely. When the water stops, close the drain valves.
3. REPAIR OF GENERATORS
A. ELEMENT REPLACEMENT:
Disconnect power from the unit. Drain the tank. Remove the front and HEATING ELEMENT ACCESS covers. Note the wire
connections. (See diagram) Remove the element wires. Using a hot water element socket, remove the element. To install a new
element, mount a new element gasket on the element. Clean the element port and add a light coat of Rectorseal No. 5 pipe
thread compound to the threads. Insert and hand tighten the element-gasket combination. Notice the element end orientation as
shown in diagram. Tighten the element until the orientation is the same as diagram, ± 15°. The gasket should be set and tight
but not deformed to a rounded or bulbous appearance. If the drain valve was removed reinstall it. Reconnect the wiring. Test the
unit per SECTION 7: INITIAL TEST. Check for leaks at the element. Replace the front and HEATING ELEMENT ACCESS
covers. (Replace with factory supplied elements only)
IMPORTANT
The blue wire connected to MAX on the PCA must be connected to
the shortest of the three level probes, the black wire (MID)
to the long probe with black tubing and the white wire (MIN) connected to the longest probe with white tubing.
B. PRINTED CIRCUIT REPLACEMENT:
Printed circuit assembly (PCA) removal and replacement must be performed in the following sequence: any other method can
damage the PCA.
IMPORTANT
The PCA’s contain static sensitive devices. Static electricity may damage PCA’s. Handle accordingly.
Disconnect power from the unit. Note and tag the positions of all wires that plug into the printed circuit. Remove all the wires
from the relays. When removing these wires, pull on the connector, not the wire. Disconnect all three wires from the water level
probe. Note: the blue wire is connected to the shortest of the triple pronged water level probe. Disconnect control cable.Remove
the PCA mounting screws. To install the board, reverse this procedure. The wire lugs must fir tightly onto the relay tabs! Test
the unit per SECTION 7: INITIAL TEST.
C. WATER SOLENOID REPLACEMENT:
Disconnect power from the unit. Turn the water supply OFF. Disconnect the water supply from the water solenoid valve.
Remove the front cover. Remove the two blue wires from the water solenoid valve. Rotate the self-tightening hose clamp so it
can be loosened with a pair of pliers. Squeeze the clamp and move it down towards the shelf and off the valve outlet tube.
Remove the two 1/4" - 20 hex head bolts and lock washers that attach the valve to the chassis. Pull the valve off the rubber fill
hose. To install the valve, reverse these instructions. Test the unit per SECTION 7: INITIAL TEST.

SECTION 7. SERVICE (continued)
D. LEVEL PROBE REPLACEMENT:
Disconnect power from the unit. Remove the front cover. Note where the blue wire is connected to the triple pronged water level
probe. Disconnect all three wires from the water level probe. Using a 1-1/4" box wrench, remove the level probe. Install a new
level probe. Use Teflon Tape on threads of probe if required. Tighten until the bottom of the plastic nut is 1/8" to 3/8" (3,2 to 9,5
mm) above the top of the port. See diagram 11. Reattach the three wires. Test the unit per SECTION 8: OPERATIONAL
TEST.
IMPORTANT
The blue wire connected to “L” on the PCA must be connected to the shortest of the three level probes, the black wire to the
probe with black tubing and the white wire to the probe with white tubing.
IMPORTANT The level probe may be extremely tight. Damage to the insulation or chassis may result unless the tank is
properly blocked or supported during probe removal or installation. It may be necessary to completely disconnect and
disassemble the generator.
