Location of Ice Machine
The location selected for the ice machine must meet
the following criteria. If any of these criteria are not
met, select another location.
• The location must be indoors.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 10°C (50°F),
but must not exceed 45°C (113°F).
• The location must not be near heat-generating
equipment or in direct sunlight.
• The counter top (or other resting surface) must be
able to support 425 kg per square meter (0.6 lb.
per square inch).
• The location must allow enough clearance for
water, drain, and electrical connections in the
rear of the ice machine.
• The location must not obstruct air flow to any
portion of the front of the ice machine.
CAUTION
The ice machine must be protected if it will be
subjected to temperatures below 0°C (32°F).
Failure caused by exposure to freezing
temperatures is not covered by the warranty. See
“Removal from Service/Winterization” on page 4-
8.
Leveling the Ice Machine
After moving the ice machine into the installation
location, it must be leveled for proper operation.
Follow these steps to level the ice machine:
1. Use a level to check the levelness of the ice
machine from front to back and from side to side.
sv1704
Checking the Levelness
2. If the ice machine is not level, adjust the leveling
glides or legs on each corner of the base of the ice
machine as necessary.
3. Check the levelness of the ice machine after each
adjustment.
4. Repeat steps 2 and 3 until the ice machine is level
from front to back and from side to side.

Electrical Service
WARNING
All wiring must conform to local, state and national
codes.
Ice Machine Voltage Phase Air-Cooled
Model Cycle Electrical Rating
QM30 230/50/1 .6 KW / 2.6 Amps
QM30 115/60/1 .6 KW/ 5.3 Amps
VOLTAGE
The maximum allowable voltage variation is ± 10%
of the rated voltage at ice machine start-up (when the
electrical load is highest).
WARNING
The ice machine must be grounded in accordance
with national and local electrical codes.
WARNING
Never use an extension cord. If an outlet is not
within reach of the ice machin e’s power cord, have
a proper amperage outlet wired closer to the ice
machine.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for
each ice machine.
NOTE: A means of disconnect must be provided for
field wiring.
ELECTRICAL RATING
The electrical rating is used to help select the wire
size of the electrical supply. The wire size (or gauge)
also depends on location, materials used, length of
run, etc., so it must be determined by a qualified
electrician.
FOR UNITED KINGDOM ONLY
As the colours of the wires in the mains lead of the
appliance may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
• The wire which is coloured green and yellow must be
connected to the terminal in the plug which is marked
with the letter E or by the earth symbol , or
coloured green or green and yellow.
• The wire coloured blue must be connected to the
terminal which is marked with the letter N or coloured
black.
• The wire which is coloured brown must be connected
to the terminal which is marked with the letter L or
coloured red.

Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
Important
If you are installing a Manitowoc water filter
system, refer to the Installation Instructions
supplied with the filter system for ice making water
inlet connections.
Follow these guidelines to install water inlet lines:
• Connect to potable water supply only.
• 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, obtain a water pressure
regulator from your Manitowoc distributor.
• Install a water shut-off valve for the ice making
water lines.
• Insulate water lines to prevent condensation.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to
prevent drain water from flowing back into the ice
machine and storage bin:
• Drain lines must have a 2.5 cm (1 inch) drop per
1 meter (40 inches) of run, and must not create
traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Insulate the bin drain line to prevent
condensation.

Plumbing must conform to state and local codes.
