Because the heat of rejection varies during the ice making cycle,
the figure shown is an average.
Air Conditioning
Heat of Rejection
Ice machines, like other refrigeration equipment, reject
heat through the condenser. It is helpful to know the
amount of heat rejected by the ice machine when sizing
air conditioning equipment where self -c on tained air cooled ice machines are installed.
This information is also necessary when evaluating the
benefits of using water-cooled or remote condensers to
reduce air conditioning loads. The amount of heat added
to an air conditioned environment by an ice machine
using a water-cooled or remote condenser is negligible.
Knowing the amount of heat rejected is also important
when sizing a cooling tower for a water-cooled
condenser. Use the peak figure for sizing the cooling
tower.
Peak
Caution
!
The ice machine must be protected if it will be
subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing
temperatures is not covered by the warranty. See
“Removal from Service/Winterization”.

GENERAL
!
Warning
All wiring must conform to local, state and national
codes.
VOLTAGE
The maximum allowable voltage variation is ±1 0% 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.
Observe correct polarity of incoming line voltage.
Fuse/Circuit Breaker
A separate fuse/circuit breaker must be provided for
each ice machine. Circuit breakers must be H.A.C.R.
rated (does not apply in Canada).
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.
ELECTRICAL REQUIREMENTS
Refer to Ice Machine Model/Serial Plate for voltage/

Water Supply and Drain Requirements
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 Arctic Puref water
filter system, refer to the Installation Instructions
supplied with the filter system for ice making water
inlet connections.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
• 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 both the ice making
and condenser water lines.
• Insulate water inlet lines to prevent condensation.
Caution
!
Do not apply heat to water valve inlet fitting. This will
damage plastic valve body.
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 1.5 inch drop per 5 feet of
run (2.5 cm per meter), and must not create traps.
• The floor drain must be larg e en o ug h to
accommodate drainage from all drains.
• Run separate bin and ice machine drain lines.
Insulate them to prevent condensatio n.
• Vent the bin and ice machine drain to the
atmosphere. Do not vent the condenser drain on
water-cooled models.
Cooling Tower Applications
(Water-Cooled Models)
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 rejectio n, 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 no t exceed 90°F
(32.2°C).
• Water flow through the condenser must n ot exceed 5
gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psi (48 kPA) between
the condenser water inlet and the outlet of the ice
machine.
• Water exiting the condenser must not exceed 110°F
(43.3°C).

GUIDELINES FOR ROUTING LINE SETS
First, cut a 2.5" (6.35 cm) circular hole in the wall or ro of
for tubing routing. The line set end with the 90° bend will
connect to the ice machine. The straight end will connect
to the remote condenser.
Follow these guidelines when routing the refrigerant
lines. This will help insure proper performance and
service accessibility.
1. Optional - Make the service loop in the line sets (as
shown below). This permits easy access to the ice
machine for cleaning and service. Do not use hard
rigid copper at this location.
2. Required - Do not form traps in the refrigeration lines
(except the service loop). Refrigerant oil must be
free to drain toward the ice machine or the
condenser. Route excess tubing in a supported
downward horizontal spiral (as shown below). Do
not coil tubing vertically.
3. Required - Keep outdoor refrigerant line runs as
short as possible.

CALCULATING REMOTE CONDENSER
INSTALLATION DISTANCES
Line Set Length
The maximum length is 100' (30.5 m).
The ice machine compressor must have the proper oil
return. The receiver is designed to ho ld a ch ar ge
sufficient to operate the ice machine in ambient
temperatures between -20°F (-29°C) and 120°F (49°C),
with line set lengths of up to 100' (30.5 m).
Line Set Rise/Drop
The maximum rise is 35' (10.7 m).
The maximum drop is 15' (4.5 m).
Caution
!
If a line set has a rise followed by a drop, another
rise cannot be made. Likewise, if a line set has a
drop followed by a rise, another drop cannot be
made.
Calculated Line Set Distance
The maximum calculated distance is 150' (45.7 m).
Make the following calculations to make sure the line set
layout is within specifications.
1. Insert the measured rise into the formula below.
Multiply by 1.7 to get the calculated rise.
(Example: A condenser located 10 feet above the
ice machine has a calculated rise of 17 feet.)
2. Insert the measured drop into the formula below.
Multiply by 6.6 to get the calculated drop.
(Example. A condenser located 10 feet below the
ice machine has a calculated drop of 66 feet.)
3. Insert the measured horizontal distance into the
formula below. No calculation is necessary.
4. Add together the calculated rise, calculated drop,
and horizont al distance to get the total calculated
distance. If this total exceeds 150' (45.7 m), move
the condenser to a new location and perform the
calculations again.
Line set rises, drops, horizontal ru ns (or combinations of
these) in excess of the stated maximums will exceed
compressor start-up and design limits. This will cause
poor oil return to the compressor.
