Air Conditioning

Heat of Rejection

2

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-contained 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.

Removing Drain Plug and Leveling the Ice Storage Bin

To avoid instability, the bin/dispenser must be installed
in an area capable of supporting the weight of the bin/
dispenser, ice machine and a full bin of ice (48" models
1000 lbs [454 kg], 30" models 750 lbs [340 kg]). The bin/
dispenser must be level side-to-side and front-to-back
before installing the ice machine.

1. Remove threaded plug from drain fitting.

2. Screw the leveling legs onto the bottom of the bin.

3. Screw the foot of each leg in as far as possible.

The legs must be screwed in tightly to prevent them
from bending.

4. Move the bin into its final position.

5. Level the bin to assure that the bin door closes and seals
and the ice machine operates properly. Use a level on
top of the bin. Turn the base of each foot as necessary
to level the bin.

6. Inspect bin gasket prior to ice machine installation. (Our
bins come with a closed cell foam gasket installed along
the top surface of the bin.)

7. Remove all panels from ice machine before lifting and
installing on bin. Remove front panel, top cover, left and
right side panels.

Air Baffle

Self-Contained Air-Cooled Only

The air-cooled baffle prevents condenser air from
recirculating. To install:

1. Loosen the back panel screws next to the condenser.

2. Align the keyhole slots in the air baffle with the screw
holes and slide the baffle down to lock in place.

Caution

Electrical Service

All electrical work, including wire routing and
grounding must conform to all applicable national and
local electrical codes.

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.)

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/
amperage specifications.

• A separate fuse/circuit breaker must be provided for
each ice machine.

• The wire size (or gauge) is dependent upon location,
materials used, length of run, etc., so it must be
determined by a qualified electrician.

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

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

Observe correct polarity of incoming line voltage.
Incorrect polarity can lead to erratic ice machine
operation. Operate equipment only on the type of
electricity indicated on the specification plate.

GROUND FAULT CIRCUIT INTERRUPTER

Ground Fault Circuit Interrupter (GFCI/GFI) protection is a
system that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to ground.
GFCI/GFI circuit protection is not recommended with our
equipment. If code requires the use of a GFCI/GFI, then you
must follow the local code. The circuit must be dedicated,
sized properly and there must be a panel GFCI/GFI breaker.
We do not recommend GFCI/GFI outlets as they are known
for more intermittent nuisance trips than panel breakers.

Maximum Length of Power

Cord

If a power cord is used, the wire size to the receptacle is
dependent upon location, materials used, length of run, etc.,
so it must be determined by a qualified electrician. Local,
state or national requirements will supersede our minimum
requirements.

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

• 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.

or colored green or green and yellow.

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.

Connect to a potable water supply only. Plumbing must

conform to state, local and national codes.

WATER INLET LINES

Follow these guidelines to install water inlet lines:

• If you are installing a water filter system, refer to the
installation instructions supplied with the filter system
for ice making water inlet connections.

• 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 psi (552 kPa), obtain a water pressure
regulator from your local distributor.

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 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.
Do not vent the condenser drain on water-cooled
models.

• A separate auxiliary drain is located in the ice machine
base to remove moisture in high humidity areas. The
drain fitting is a female socket for 1/2" CPVC pipe. The
drain is sealed and the seal must be removed before
attaching the drain fitting/tubing. Tap the seal out with a
wooden dowel or similar tool. Seal the CPVC pipe to the
ice machine socket with silicone sealant to allow future
removal.

• Install a water shut-off valve for both the ice making and
condenser water lines.

• Insulate water inlet lines to prevent condensation.

Do not apply heat to water valve inlet fitting. This will
damage plastic water inlet connection.

WATER-COOLED CONDENSER WATER PRESSURE

Water pressure at the condenser cannot exceed 150 psig
(1034 kPa) with the standard water-regulating valve.
Contact your distributor if your water pressure is greater
than 150 psig (1034 kPa). A special order condenser/water­regulating valve is available that allows water pressure up to
350 psig (2413 kPa).

The Commonwealth of Massachusetts requires that all
water-cooled models must be connected only to a
closed loop, cooling tower system.

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 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 7 psi (50 kPa) between the
condenser water inlet and the outlet of the ice machine.

• Water exiting the condenser must not exceed
110°F

(43°C).

REMOTE ICE MACHINE REFRIGERANT CHARGE

Each remote ice machine ships from the factory with a
refrigerant charge appropriate for installation with line sets
of up to 50' (15 m). The serial tag on the ice machine
indicates the refrigerant charge.

Additional refrigerant may be required for installations
using line sets between 50' and 100' (15-30 m) long. If
additional refrigerant is required, refer to the chart below for
the correct amount to be added.

GENERAL

Condensers must be mounted horizontally with the fan
motor on top with nothing obstructing it. There must be at
least a 16" (41 cm) clearance from the bottom for air intake.
The front coupling panel and one other panel (back or side)
must also be unobstructed.

Remote condenser installations consist of vertical and
horizontal line sets between the ice machine and the
condenser. When combined, they must fit within approved
specifications. The following guidelines, drawings and
calculation methods must be followed to verify a proper
remote condenser installation.

The compressor warranty (including the labor
replacement warranty) will not apply if the remote ice
machine is not installed according to specifications.

The warranty also will not apply if the refrigeration
system is modified with a condenser, heat reclaim
device, or other parts or assemblies not manufactured
by us unless we specifically approved the component in
writing.

GUIDELINES FOR ROUTING LINE SETS

First, cut a 2.5" (6.35 cm) circular hole in the wall or roof 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 ensure proper performance and service
accessibility.

1. Optional - Make the service loop in the line sets (as
shown in Routing Line Sets graphic). 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 m).

The ice machine compressor must have the proper oil
return. The receiver is designed to hold a charge 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 m).

Line Set Rise/Drop

The maximum rise is 35' (10.7 m).

The maximum drop is 15' (4.5 m).

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 m).

Line set rises, drops, horizontal runs (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.

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

horizontal distance to get the total calculated
distance. If this total exceeds 150' (45 m), move the

condenser to a new location and perform the
calculations again.

Maximum Line Set Distance Formula

Step 1. Measured Rise (35' [10.7 m] Maximum) ______ x 1.7 = _______ Calculated Rise
Step 2. Measured Drop (15' [4.5 m] Maximum) ______ x 6.6 = _______ Calculated Drop
Step 3. Measured Horizontal Distance (100' [30 m] Maximum) _______ Horizontal Distance
Step 4. Total Calculated Distance 150' (45 m) _______ Total Calculated Distance

ROUTE THE LINE SET

• Route the line set to avoid traps and kinks.

• Minimize the amount of line set exposed on the roof.

CONNECT THE LINE SET

• Cut the line set to the correct length.

• Purge line set with dry nitrogen while brazing.

• Line set shutoff valves on the ice machine must remain
closed and be protected from heat during brazing.

PRESSURE TEST AND EVACUATE LINE SET AND CONDENSER

• Lineset shutoff valves must remain closed until pressure
testing and evacuation are complete.

• Pressure test @ 150 psi (1000 kPa) for a minimum of 15
minutes.

• Minimum evacuation level is 500 microns.

• Pressure test the line set and condenser with 150 psig of
dry nitrogen. Add nitrogen at the line set shutoff valves
located at the back of the ice machine head section.
Complete the pressure test, verify no leaks are present
and remove the nitrogen from the system before
connecting the vacuum pump.

OPEN LINE SET VALVES

You will not hear refrigerant flow when the valves are
opened. Refrigerant will not flow until the ice machine is
started and the solenoid valve opens.

• All valve caps must be reinstalled, tightened and leak­checked to assure no refrigerant leakage exists.

• Counterclockwise opens all valves.
