" RISK OF PERSONAL INJURY, PROPERTY DAMAGE, EQUIPMENT

FAILURE, OR FIRE.

" Refer all maintenance to qualified personnel.
" Never operate this equipment with covers, panels, or other parts removed

or not properly secured.

" Warn all users to clean up all spills immediately, keep storage bin doors

closed, and report any leaks or unusual sounds to responsible
maintenance personnel.

" Use suitable lifting techniques and watch for sharp edges.

Installation Specifications

Ampacity: Minimum ampacity does not indicate typical running current value. Refer to equipment
NAME PLATE data. Use minimum ampacity value for sizing branch circuit conductors up to 25
feet length. For conductor length over 25 feet up to 100 feet, increase 1 AWG size. Over 100
feet requires 2 or more AWG size increase.

Branch circuit protection: Proper protection must be provided by either fuse(s) or HACR type
circuit breaker(s). Each cuber must be provided with a separately protected circuit with no other
load(s). A fused disconnect installed adjacent to each ice maker is recommended , and may be
required by local codes. NORMAL protector size is based on rated voltage and operation at
lower than extreme temperature limits. When branch circuit conductors are sized to permit,
increasing the protector size (up to the specified maximum) may avoid nuisance protector opening
under harsh operating conditions.

Water supply: Minimum 20 psig supply pressure while the ice maker is filling is required. Maximum
supply pressure is 100 psig. The water fill flow rate is 0.6 GRM for each GT3XX and 1 GPM for
each GT5XX machine. Backflow prevention is provided by an internal air gap (accepted by
NSF). If additional protection is required by local codes, any device(s) and installation of the
same, including specification and cost, are the responsibility of the installation specifier.

Ice maker drain: The size of the gravity drain for the ice maker rinse and purge water must not
be reduced. Individual drains from stacked ice makers may be discharged into a standpipe or
manifold with a minimum 1-1/2 inch air gap at each ice maker connection.

Liquid condenser coolant pressure drop: Condenser coolant pressure drop may reach 20 psig
during peak load with 85OF. coolant temperature at recommended refrigerant high-side pressure.
The condenser coolant (water) regulating valve may require adjustment due to variations in the
coolant supply characteristics to provide optimum efficiency.

All models are intended FOR INDOOR USE ONLY with PERMANENT CONNECTION TO THE
FIELD ELECTRICAL SUPPLY.

Note for GT5XX Series Only:

Remote air-cooled condensers supplied by KOLD-DRAFT may be installed
outdoors, and they require a separate electrical supply.

Other operating condition requirements:

Ice maker ambient air temperature: MINIMUM 45°F.; MAXIMUM 90°F.
Remote condenser ambient air temperature: CONSULT SERVICE MANUAL
*Ice maker ambient temperatures less than 50°F may cause erratic bin thermostat operation.

Potable water and condenser liquid supply:

Temperature: MINIMUM 45°F.; MAXIMUM 90°F.
Pressure: MINIMUM 20 psig; MAXIMUM 100 psig**
*Potable water temperatures less than 50°F are likely to cause cold-water thermostat operation
(see SERVICE MANUAL).
**If regulator is used, recommended setting is 30 to 50 psig.

INSTALLATION

NOTE: For Stacked GT3XX installations, refer to the specific stacking instructions before proceeding.

GT5XX ice maker cannot be stacked.

Location:

1. Position the ice storage bin with the following minimum clearances around the ice maker
for ventilation and utility connections:

GT3XX Ice Makers GT5XX Ice Makers

REAR : 6 inches 8 inches
RIGHT SIDE: 6 inches 4 inches
LEFT SIDE: 6 inches 4 inches
TOP: 6 inches 8 inches

Level Equipment:

2. Level the bin with adjustable legs, or by shimming if the bin is to be sealed to the floor. If
gaps due to shims are greater than 1/8 inch, install a cove molding around the bin
bottom. Seal the bin or molding to the floor with NSF Certified RTV silicon sealant (Dow­Corning RTV 732 or equal).

Cabnet Panel, Ice Chute and Drain Pan Removal:

3. Remove the cabinet panels as follows:

TOP: GT3XX, Lift the front edge and pull forward until the rear clip is

disengaged from the chassis.

GT5XX, lift the front edge and push backward until the rear

catch is disengaged.
FRONT: Remove the (4) screws at the bottom and front-sides, pull forward.
SIDES : Pull forward and lift to disengage the clips from the chassis.

4. Remove the, ice chute and drain pan. Peel off the protective film from the ice maker and
the bin exterior panels.

Gasket the Bin Top:

5. Install gasketing on top of bin. Gasket material must be positioned so that it extends to
all the outside edges of the ice maker chassis.

Position the Ice Maker on the Bin Top:

6. CAREFULLY place the ice maker onto the bin, note the alignment of the mounting holes in
the ice maker if mounting means (holes) are provided on the bin. 1/4”-20 capscrews are
provided for securing the ice maker to bin. Consult the ice bin installation instructions for
for additional information.
