SAFETY PRECAUTIONS
This unit has been specifically designed to provide protection against personal injury. To ensure continued protection
observe the following:
Disconnect power to the unit before servicing following all lock out/tag out procedures established by the user. Verify
all of the power is off to the unit before any work is performed.
Failure to disconnect the power could result in serious injury, death or equipment damage.
Always be sure to keep area around the unit clean and free of clutter. Failure to keep this area clean may result in
injury or equipment damage.
SHIPPING AND STORAGE
Before shipping, storing, or relocating the unit, the unit must be sanitized and all sanitizing solution must be drained
from the system. A freezing ambient environment will cause residual sanitizing solution or water remaining inside the
unit to freeze resulting in damage to internal components.
MOUNTING IN OR ON A COUNTER
When installing the unit in or on a counter top, the counter must be able to support a weight in excess of 500 - 169lbs,
700 - 179lbs, 1000 - 231lbs and 2000 - 376lbs. to insure adequate support for the unit.
Failure to Comply Could Result in Serious Injury, Death or Equipment Damage.
NOTE: Many units incorporate the use of additional equipment such as icemakers. When any
addition equipment is used you must check with the equipment manufacturer to determine the
additional weight the counter will need to support to ensure a safe installation.
Very high discharges pressure is present in system. Quick disconnects on your gages will minimize danger and loss
of refrigerant.
Unit requires separate electrical line. See instruction manual for proper fuse size.
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.

Continuous Flow Icemaker Installation and Service Manual
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. WATER INLET HOOKUP
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.

F. E LECTRICAL 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
1. 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
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
mounting screw that was removed in Step 1 to secure bracket to base. See Figure 4.

INITIAL START UP, CHECKS AND ADJUSTMENT INSTRUCTIONS
NOTE: Do not start unit before completing installation steps on pages 6 through 8.
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

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 15). 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
this manual or call for factory assistance at 1-800-Service.
