Water Supply and Drains

POTABLE WATER REQUIREMENTS

Local water conditions may require treatment of the

water to inhibit scale formation, filter sediment, and

remove chlorine odor and taste.

Follow these guidelines to install water inlet lines:

• Plumbing must conform to local codes.

• Do not connect the ice machine to a hot water

supply. Be sure all hot water restrictors installed for

other equipment are working. (Check valves on sink

faucets, dishwashers, etc.)

• If water pressure exceeds the maximum

recommended pressure of 80 psig (552 kPa), obtain

a water pressure regulator from your Manitowoc

distributor.

• Install a water shut-off valve and union for potable

water and water cooled condenser lines.

• Insulate water inlet lines to prevent condensation.

DRAIN CONNECTIONS

• Drain lines must have a 1.5 inch drop per 5 feet of

run (2.5 cm per meter), and must not create traps.

• The floor drain must be large enough to

accommodate drainage from all drains.

• Run separate bin and ice machine drain lines.

Insulate them to prevent condensation.

• Vent the bin and ice machine drain to the

atmosphere. The ice machine drain requires an 18"

vent. Do not vent the condenser drain on water-

cooled models.

• Drains must have a union or other suitable means to

allow in place disconnection from the ice machine

when servicing is required.

• Base drain - Use 1/2” CPVC tubing and silicone

sealant to connect to this optional drain.

Warning

Connect to a potable water supply only.

Section 2 Installation

Part Number 000006505 Rev02 12/19 7

WATER SUPPLY AND DRAIN LINE SIZING/CONNECTIONS

COOLING TOWER APPLICATIONS

(Water-Cooled Models Only)

A water cooling tower installation does not require

modification of the ice machine. The water regulator

valve for the condenser continues to control the

refrigeration discharge pressure.

It is necessary to know the amount of heat rejection, and

the pressure drop through the condenser and water

valves (inlet and outlet) when using a cooling tower on

an ice machine.

• Water entering the condenser must not exceed 90°F

(32°C).

• Water flow through the condenser must not exceed

5 gallons (19 liters) per minute.

• Allow for a pressure drop of 8 psi (1030 kPa)

between the condenser water inlet and the outlet of

the ice machine.

• Water exiting the condenser must not exceed 110°F

(43°C).

• Do not connect to the potable water filter system.

• Contact your distributor if your water pressure is

greater than 150 psig (1030 kPa). A special order

condensing unit is available that allows water

pressure up to 350 psig (2410 kPa).

Electrical Service

GENERAL

All electrical work, including wire routing and grounding,

must conform to local, state and national electrical

codes. The following precautions must be observed:

• The ice machine must be grounded.

• A separate fuse/circuit breaker must be provided for

each condensing unit.

• A qualified electrician must determine proper wire

size dependent upon location, materials used and

length of run (minimum circuit ampacity can be used

to help select the wire size).

• The maximum allowable voltage variation is +/-10 of

the rated voltage at compressor start-up (when the

electrical load is highest).

• Check all green ground screws in the control box and

verify they are tight before starting the ice machine.

• Verify polarity is correct. Incorrect polarity can lead to

erratic ice machine operation and a safety issue. This

is especially critical on 230 volt / 50 cycle ice

machines.

FUSE/CIRCUIT BREAKER

The ice machine head section and condensing unit are

wired independently of each other.

A dedicated circuit and a separate fuse/circuit breaker

are required for each ice machine and condensing unit.

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the

wire size of the electrical supply. (Minimum circuit

ampacity is not the ice machine’s running amp load.)

The wire size (or gauge) is also dependent upon

location, materials used, length of run, etc., so it must be

determined by a qualified electrician. Manitowoc Ice

requires minimum #8 AWG for S2170C condensing unit

applications.

GROUND FAULT CIRCUIT INTERRUPTER

We do not recommend the use of a GFCI/GFI circuit

protection with our equipment. If a GFCI/GFI is required

by code use a GFCI/GFI breaker rather than outlet

which is more prone to intermittent nuisance trips than

panel circuit breakers.

!

Warning

All wiring must conform to local, state and national

codes.

!

Warning

The ice machine and condensing unit must be

grounded in accordance with national and local

electrical codes.

Important

Observe correct polarity of incoming line voltage.

For United Kingdom Only

As the colors of the wires in the mains lead of the appliance

may not correspond with the colored markings identifying

the terminals in your plug, proceed as follows:

• The wire which is colored

green and yellow must be

connected to the terminal in the plug which is marked

with the letter E or by the earth ground symbol or

colored green or green and yellow.

• The wire colored

blue must be connected to the terminal

which is marked with the letter N or colored black.

• The wire colored

brown must be connected to the

terminal which is marked with the letter L or colored red.

Part Number 000006505 Rev02 12/19 9

Electrical Requirements

Local or state electrical code, length of wire run or materials used, can increase the minimum wire or breaker size

requirement. A qualified electrician must determine the wire and breaker size, although the minimum wire size must

meet or exceed the specifications in these charts. Refer to the condensing unit serial plate to verify electrical data.

Section 3

Operation

Ice Making Sequence of Operation

Water Purge Cycle

The ice machine purges any remaining water from the

water trough down the drain.

Freeze Cycle

Water flows across the evaporator and the refrigeration

system chills the evaporator. Ice builds on the

evaporator until water contacts the ice thickness probe.

Harvest Cycle

Any remaining water is purged down the drain as

refrigerant gas warms the evaporator. When the

evaporator warms, the sheet of cubes slides off the

evaporator and into the storage bin. If all cubes fall clear

of the water curtain (or ice damper) the ice machine

starts another freeze cycle.

Off Cycle

If the water curtain or ice damper are held open by ice

cubes the ice machine shuts off. When the water curtain

or ice damper closes the ice machine starts a new cycle

at the water purge.

Control Board Timers

The control board has the following non-adjustable

timers:

• The ice machine is locked into the freeze cycle for 6

minutes before a harvest cycle can be initiated.

Freeze lock is bypassed after moving the toggle

switch from OFF to ICE position for the first cycle

only.

• The maximum freeze time is 60 minutes at which

time the control board automatically initiates a

harvest sequence.

• The maximum harvest time is 3.5 minutes for single

evaporators and 7 minutes for multiple evaporator

model. The control board automatically initiates a

freeze sequence when these times are exceeded.

SAFETY LIMITS

Safety limits are stored and indicated by the control

board after three cycles. The number of cycles required

to stop the ice machine varies for each safety limit.

• Safety Limit 1 all models - If the freeze time reaches

60 minutes, the control board automatically initiates a

harvest cycle. If 6 consecutive 60-minute freeze

cycles occur, the ice machine stops.

• Safety Limit 2 single & twin evaporator models - If the

harvest time reaches 3.5 minutes, the control board

automatically returns the ice machine to the freeze

cycle. If 500 consecutive 3.5 minute harvest cycles

occur, the ice machine stops.

• Safety Limit 2 S3000C/SF3000C - If the harvest time

reaches 7 minutes, the control board automatically

returns the ice machine to the freeze cycle. If 500

consecutive 7 minute harvest cycles occur, the ice

machine stops.

• Safety Limit 3 S3000C/SF3000C - If the low

refrigerant pressure control opens, the ice machine

shuts off and starts a 5 minute delay period. If 3

consecutive low pressure events occur the ice

machine stops and flashes the harvest light.

Use the following procedures to determine if the control

board contains a safety limit indication.

1. Move the toggle switch to OFF.

2. Move the toggle switch back to ICE. Watch the

safety limit lights/harvest light on the control board. If

a safety limit has been recorded, the corresponding

light will blink once, twice or three times to indicate

which safety limit stopped the ice machine.

Section 3 Operation

Part Number 000006505 Rev02 12/19 17

Operational Checks

GENERAL

Manitowoc ice machines are factory-operated and

adjusted before shipment. Normally, new installations do

not require any adjustment.

To ensure proper operation, always follow the

Operational Checks:

• when starting the ice machine for the first time

• after a prolonged out of service period

• after cleaning and sanitizing

NOTE: Routine adjustments and maintenance

procedures are not covered by the warranty.

ICE THICKNESS CHECK

After a harvest cycle, inspect the ice cubes in the ice

storage bin. The ice thickness probe is factory-set to

maintain the ice bridge thickness at 1/8” (3 mm).

NOTE: Make sure the water curtain is in place when

performing this check. It prevents water from splashing

out of the water trough.

1. Inspect the bridge connecting the cubes. It should

be about 1/8” (3 mm) thick.

2. If adjustment is necessary, turn the ice thickness

probe adjustment screw clockwise to increase

bridge thickness, counterclockwise to decrease

bridge thickness. Set at 1/4” gap between ice

machine and evaporator as starting point, then

adjust to achieve a 1/8” bridge thickness.

NOTE: Turning the adjustment 1/3 of a turn will change

the ice thickness about 1/16” (1.5 mm).

Ice Thickness Check

3. Make sure the ice thickness probe wire and the

bracket do not restrict movement of the probe.

Important

Scroll refrigeration compressors must be

operated for a minimum break in period of 24

hours before full ice production will be reached.

mineral deposits. Ice machine sanitizer disinfects and

removes algae and slime.

Step 1 Remove front door and top cover. This will allow

easiest access for adding cleaning and sanitizing

solutions.

Step 2 Set the toggle switch to the OFF position after

ice falls from the evaporator at the end of a Harvest

cycle. Or, set the switch to the OFF position and allow

the ice to melt off the evaporator.

Step 3 Remove all ice from the bin/dispenser.

Step 4 Place the toggle switch in the CLEAN position.

The water will flow through the water dump valve and

down the drain. Wait until the water trough refills and

water flows over the evaporator, then add the proper

amount of ice machine cleaner.

Step 5 Wait until the clean cycle is complete

(approximately *35 minutes). Then place the toggle

switch in the OFF position and disconnect power to the

ice machine (and dispenser when used).

NOTE: *S3300/ST3000 Only - 80 minutes.

larger quantity of solution may be required. Use the ratio

in the table below to mix enough solution to thoroughly

clean all parts.

Step 8 Use 1/2 of the descaler/water mixture to

descale all components. The descaler solution will foam

when it contacts lime scale and mineral deposits; once

the foaming stops use a soft-bristle nylon brush, sponge

or cloth (NOT a wire brush) to carefully clean the parts.

Soak parts for 5 minutes (15 - 20 minutes for heavily

scaled parts). Rinse all components with clean water.

Step 9 While components are soaking, use 1/2 of the

descaler/water solution to clean all foodzone surfaces of

the ice machine and bin (or dispenser). Use a nylon

brush or cloth to thoroughly descale the following ice

machine areas:

• Side walls

• Base (area above water trough)

• Evaporator plastic parts - including top, bottom, and

sides

• Bin or dispenser

Rinse all areas thoroughly with clean water.

SANITIZING PROCEDURE

Step 10 Mix a solution of sanitizer and warm water.

Step 11 Use 1/2 of the sanitizer/water solution to

sanitize all removed components. Use a spray bottle to

liberally apply the solution to all surfaces of the removed

parts or soak the removed parts in the sanitizer/water

solution. Do not rinse parts after sanitizing.

Step 12 Use 1/2 of the sanitizer/water solution to

sanitize all foodzone surfaces of the ice machine and bin

(or dispenser). Use a spray bottle to liberally apply the

solution. When sanitizing, pay particular attention to the

following areas:

• Side walls

• Base (area above water trough)

• Evaporator plastic parts - including top, bottom and

sides

• Bin or dispenser

Do not rinse the sanitized areas.

Step 13 Replace all removed components.

Step 14 Wait 30 minutes.

Step 15 Reapply power to the ice machine and place

the toggle switch in the CLEAN position.

Step 16 Wait until the water trough refills and water

flows over the evaporator (approximately 3 minutes).
