SAFETY INFORMATION

Recognize Safety Information

This is the safety-alert symbol. When you see this
symbol on our machine or in this manual, be alert to
the potential of personal injury.

Follow recommended precautions and safe operating
practices.

Understand Signal Words

A signal word - DANGER, WARNING, CAUTION is
used with the safety-alert symbol. DANGER identifies
the most serious hazards.

DANGER

Safety signs with signal word DANGER or WARNING
are typically near specific hazards.

General precautions are listed on CAUTION safety
signs. CAUTION also calls attention to safety mes­sages in this manual.

WARNING

CAUTION

Follow Safety Instructions

Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in
good condition. Replace missing or damaged safety signs. Learn how to operate the machine and how to
use the controls properly. Do not let anyone operate the machine without instructions. Keep your machine in
proper working condition. Unauthorized modifications to the machine may impair function and/or safety and
affect the machine life.

CAUTION: Very high discharges pressure is present in system. Quick disconnects on your
gages will minimize danger and loss of refrigerant.

CAUTION: Unit requires separate electrical line. See instruction manual for proper fuse
size.

WARNING: There must be adequate clearance around icemaker. Allow minimum 6” air
intake and 4” air exhaust for air exhaust and panel removal.

NOTE: Unit must be installed per local plumbing and electrical codes. See Installation manual for
unit requirements. Failure to do so may cause damage to unit, which would void unit warranty.

NOTE: Using any parts other than genuine factory manufactured parts relieves the manufacturer of all
liability.

NOTE: Manufacturer reserves the right to change specifications at any time.

INSTALLATION

This section covers unpacking and inspection, selecting location, installing unit, preparing for operation, and op­eration.

A. REMOVE ICEMAKER FROM CARTON

1. Keep unit in the upright position, remove carton and pallet from unit and inspect unit for damage. Upon in­spection of unit, if any damage is found, file a claim with carrier immediately.

2. Locate startup card either on outside of container or on plastic liner. Fill in proper information and send one
copy to factory, and other copy to distributor. Postage is prepaid.

B. CABINET REMOVAL

1. Front Panel—Remove 4 screws and pull forward.

2. Top Panel—Remove screws and lift upward. 4 screws 500/700, 6 screws 1000.

3. Side Panel—Remove 4 screws and pull forward.

4. Back Panel—Should not be removed.

C. PREPARATION OF INSTALLATION SITE

1. The refrigeration system on air cooled units requires airflow, so a well ventilated area should be chosen. A
minimum of 6 inches must be maintained, free of any obstructions, for air intake. A minimum of 4 inches
clearance is required for air exhaust.

2. The unit can be installed either on an ice storage bin or ice dispenser using the proper adapter kits. (Refer
to sales literature for information.) The install is kit provided with each icemaker and adapter kits will supply
everything to locate unit correctly. In all cases the icemaker should be sealed all around the base with an
NSF listed sealant. (63804815B)

D. W ATER INLET HOOK UP

1. Water Inlet—fitting is a 1/4 SAE male flare located at the rear of the unit. Connect water supply with a 1/4
SAE flare nut and 1/4” copper or flexible tubing or larger.

2. Water Pressure—Unless otherwise specified, the unit is designed to operate on water pressures between
10 P.S.I. and 90 P.S.I. (NOTE: for pressures above 90 P.S.I. a regulator must be installed.)

3. Condenser Inlet Connections—Use a separate 3/8 copper line or larger water line. Connect to 3/8 FPT
fitting on water modulating valve.

4. Filter/Conditioners are recommended on supply lines to icemakers. Never run the water supply to water
cooled condenser through filter/conditioner, it uses up the cartridge unnecessarily and a saturated cartridge
can starve the icemaker causing premature component damage. Separate water supplies are recom­mended.

NOTE: Unit must be installed per local plumbing code BOCA.

E. DRAIN CONNECTION

1. Overflow Line—is a 3/8 I.D. flexible tube located at the rear of the unit. Extend this line to proper drain.

2. Condenser Outlet—is a 3/8 FPT located on the rear panel.

NOTE: Unit must be installed per local plumbing code. BOCA.

638085278

F. ELECTRICAL SUPPLY

1. Power Access—is provided with a 7/8 dia. knockout hole in the rear panel. Route incoming power in
conduit, through rear panel to icemaker electrical control box. Make connections to wires provided in the
control box and ground lug/screw.

2. Fused Line—should be checked and sized according to electrical rating shown on unit nameplate.

G. AUGER ENGAGEMENT

Be certain that auger is fully engaged to lower drive and extruding head is fully engaged into evaporator.

H. BIN CONTROL

1. Remove tape holding control to white ice chute and also remove control bracket mounting screw located in
base of unit behind electrical box. (Screw will be used later to fasten bin control bracket to base of unit).

2. Slide control and bracket down chute to base of unit. very carefully guide control and bracket through 1/2
hole in front of ice chute. Use CAUTION to be sure control goes into bin, not between base of unit and

bin top.

3. Check location of bin control, it should be directly under ice chute at a 45_ angle. With control in place use
mounting screw that was removed in step 1 to secure bracket to base. See Figure 4

FIGURE 4. BIN CONTROL

INITIAL START UP, CHECKS AND ADJUSTMENT INSTRUCTIONS

NOTE: Do not start unit before completing installation steps on pages 7 and 9.

Turn on water supply (if unit is water cooled turn water on to condenser also) turn on main power switch (lo­cated on top of electrical box), and make the following system checks:

NOTE: If unit will not start be sure water reservoir is full. Low water safety control must be properly
adjusted to start and shut down unit. If water level drops below bottom of reservoir, unit must shut
down. Adjustment is made by moving magnet up or down.

Water Level—If necessary adjust float by bending float arm up or down as needed, push float assembly down

until unit stops running. Release float and unit will restart. Keep water in reservoir at level line while unit is in
operation. See Figure 5

Low Water Safety Control—Adjust magnet by bending magnet arm as needed to shut unit down if water level
drops below bottom of reservoir.

Bin Control—Place ice around probe, unit should shut down in one minute. Remove ice from around probe,
unit should start in two minutes.

NOTE: For altitudes over 1000 feet above sea level, adjust range screw (behind end cover). Half turn
max. raises setting 4_F approx.

FIGURE 5. ICEMAKER FLOAT ASSEMBLY

Water modulating valve (water cooled units only)—Opening point of condenser water modulating valve

should be set to maintain proper operating pressure in the refrigeration system high side. (see chart on page

16). Closing point of valve should be set low enough to close valve during compressor stand by periods. To
raise, turn counterclockwise, to lower turn clockwise.

NOTE: If any of these checks or adjustments cannot be achieved, refer to Troubleshooting Section of
this manual or call for factory assistance at 1–800–Service.
