Electrical Service

GENERAL

Observe correct polarity of incoming line voltage.

All wiring must conform to local, state and national
codes.

Prepare electrical circuit before installation of your ice
machine. Installation requires a grounded (three-pr ong),
polarized receptacle with a separate fuse/circuit breaker
in an electrical service box.

VOLTAGE

The maximum allowable voltage variation is ±1 0% of the
rated voltage at ice machine star t-up (when the electrical
load is highest).

The ice machine must be grounded in accordance
with national and local electrical codes.

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 provide d fo r
each ice machine.

• The maximum allowable voltage variation is +/-10%
of the rated voltage at ice machine start-up (when the
electrical load is highest).

Incorrect polarity can lead to erratic ice machine
operation and a safety issue.

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.)

• Check all green ground screws in the control box and
verify they are tight before starting the ice machine.

• Manitowoc’s recommended minimum wire size is
#14 for less than 100’ or #12 for more than 100’ to
200’ (solid copper conductor only). The
recommended breaker is 15 amp. Local or state
electrical code, length of run or materials used, can
increase the minimum wire gauge required. A
qualified electrician must determine the pr op er w ire
size, although #14 is the minimum size allowed.

Section 3 Ice Machine Operation

Sequence of Operation

Depending on ambient conditions and cold water supply
temperature, the ice making process will take
approximately 30 minutes.

1. Initial Start-Up or Start-Up After Automatic Shut­Off — Water Fill

Before the compressor starts, the water inlet valve
will energize to purge old water from the system for
about 3 minutes.

2. Refrigeration System Start-Up

The compressor starts after the Water Fill cycle and
remains on throughout the Freeze and Harvest
cycles. The condenser fan motor starts and runs
throughout the Freeze cycle.

3. Freeze

The water pump sprays water into the inverted cup s.
The water freezes layer by layer, until an ice cube
forms in each cup. The control system will adjust the
length of the Freeze cycle to conditions.

4. Harvest

The water pump shuts off and the water inlet valve
starts up to assist harvest and refill the water sump.
The evaporator is warmed, allowing the cubes to
release from the evaporator and drop into the
storage bin. The control system will adjust the length
of the Harvest cycle to conditions and regulate
whether the condenser fan will run.

5. Automatic Shut-Off

The level of ice in the storage bin controls the ice
machine shut-off. When the bin is full, ice will
contact the bin thermostat bulb holder. The bin
thermostat bulb cools, which stops the ice machine.
The ice machine remains off until ice no longer
contacts the bin thermost at bulb holder and the
thermostat bulb warms up. The increase in
temperature will restart the ice machine (step 1).

At the end of the Harvest cycle, the ice machine will
start another Freeze cycle (Step 3).

low and the bin thermostat can be adjusted as follows:

HAZARDOUS MOVING PARTS

Power is supplied to ice machine during this
procedure. Avoid contact with the fan bl ade and the
electrical connections.

1. To access the thermostat, remove the two screws
attaching the front grill and remove the grill.

The bin thermostat stops the ice machine when the bin
is full. It is preset for normal ambient temperatures and
adjustments are usually not required.

The thermostat is functioning correctly if, when three ice
cubes are placed on the thermostat tube for 5 minutes,
the ice machine stops. The ice machine should restart
5 minutes after the cubes are removed.

2. Turn the thermostat to the left to decrease the level
of ice before automatic shut-off. Turn to the right to
increase the level of ice before automatic shut-off.

Caution

Exterior Cleaning

Clean the area around the ice machine as often as
necessary to maintain cleanliness and efficient
operation. Use cleaners designed for use with stainless
steel products.

Sponge any dust and dirt off the outside of the ice
machine with mild soap and water. Wipe dry with a
clean, soft cloth.

Heavy stains should be removed with stainless steel
wool. Never use plain steel wool or abrasive pads. They
will scratch the panels.

Cleaning the Condenser

GENERAL

Disconnect electric power to the ice machine at the
electric service switches before cleaning the
condenser.

A dirty condenser restricts airflow, resulting in
excessively high operating temperatures. This reduces
ice production and shortens component life. Clean the
condenser at least every six months. Follow the steps
below.

1. Remove Front Grill by removing two screws. Clean
Grill openings before replacing.

2. Clean the outside of the condenser with a soft brush
or a vacuum with a brush attachment. Clean from
top to bottom, not side to side. Be careful not to
bend the condenser fins.

3.Shine a flashlight through the condenser to chec k for
dirt between the fins. If dirt remains:

A. Compressed air can be blown through th e

condenser fins. This procedure will raise
considerable dust and is best performed
outside. Be careful not to bend the fan blades.

B. If dirt or grease remains between the fins or the

condenser fins are bent or flattened, consult
your service representative.

Removal from Service/ Long Term Storage/
Winterization

GENERAL

Special precautions must be taken if the ice machine is
to be removed from service for an extended period of
time or exposed to ambient temperatures of 32°F (0°C)
or below.

If water is allowed to remain in the ice machine in
freezing temperatures, severe damage to some
components could result. Damage of this nature is
not covered by the warranty.

Follow the procedure below.

SELF-CONTAINED AIR-COOLED ICE MACHINES

1. Perform a cleaning and sanitizing procedure to
prevent mildew growth.

2. Disconnect the electric power at the circuit breaker
or the electric service switch.

3. Turn off the water supply .

4. Remove the water from the water trough.

5. Disconnect and drain the incoming ice-making water
line at the rear of the ice machine.

6. Disconnect vinyl hose from water pump and allow to
drain.

7. Make sure water is not trapped in any of the water or
drain lines. Compressed air can be used to blow out
the lines.

8. Use a spray bottle and a solution of sanitizer/water
(0.50 oz/ 1 gal) and spray all interior surfaces. Do
not rinse, allow to air dry.

9. Block the door partially open to provide air exchange
and prevent mildew growth.
