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 potentially of personal injury.
Follow recommended precautions and safe operating
practices.
Understand Signal Words
A signal word - DANGER, WARNING, OR CAUTION
is used with the safety-alert symbol. DANGER identi-
fies 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 the system. Quick disconnects on
your gages will minimize danger and loss of refrigerant.
CAUTION: The Unit requires a separate electrical line. See Instruction Manual for proper
fuse size.
WARNING: There must be adequate clearance around the Icemaker. Allow 25–inches on the
front side for service access, 4–inches on side opposite the storage bin, and 4–inches on
the back side for air exaust.
NOTE: The Unit must be installed per local plumbing and electrical codes. Failure to do so may cause
damage to the Unit which would void the factory warranty.
NOTE: Using parts other thean genuine factory manufactured parts relieves the manufacturer of all
liability. The manufacturer reserves the right to change specifications at any time.

PRE–INSTALLATION
Freight Damage Claim
The delivery of your equipment (Frieght Company, Distributor, or dealer) is responsible for loss or damage of
your shipment. All claims must be filed with the deliverer of your equipment. Please follow the steps below to
determine if your shipment is satisfactory or if a claim must be filed:
1. Check the number of products delivered against the number of products listed on the delivery receipt.
Should the totals not match, have the driver note all errors on both copies and both you and the driver sign
and date said notation.
2. Inspect all cartons for visible damage. Open and inspect as required before the driver leaves and have him
or her note any damage on the receipts. All damaged claims must be inspected within 15 days of delivery.
Notify your carrier immediately if concealed damage is found after delivery.
3. Should concealed damage be found when the product is unpacked, retain the packing material and the
product and request an inspection from the deliverer.
4. All claims for loss or damage should be filed at once. Delays in filing will reduce the chance of achieving a
satisfactory resolution to the claim.
Counter
1. A flat and level counter space sufficiently strong to support the weight of the Dispenser and the Icemaker.
The Icemaker may be installed on the left or the right side of the Dispenser.
2. General Requirements:
A. The front of the Icemaker must be free of obstructions.
B. Allow a 4–inch minimum clearance between exaust side of the Icemaker and adjacent equipment.
C. A louvered front panel (12–inches X 12–inches) aligned with the air inlet of the Icemaker and ade-
quate ventilation (1.5 Sq. feet opening) in the counter for exaust air.
D. A removable panel in the counter face (from 2–inches below the top of the counter to the floor, a mini-
mum of 17–inches wide) to allow removal of the Icemaker.
Electrical
Two separate 20 amp, 120VAC, 60 Hz electrical circuits.
Drain
One drain beneath the counter at floor level which will accomodate both the drain from the Icemaker and the
Dispenser.

INSTALLATION
1. Keep unit in the upright position, remove carton and pallet from the Icemaker and inspect for damage. 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
to factory, and other copy to distributor. Postage is prepaid.
3. Install the Dispenser first, following installation instructions supplied with the Dispenser.
4. Remove the two hole plugs from the side of the dispenser.
A. The plugs are pressed in and sealed with a silastic sealant. To remove pry the outside cap off and
then press the inside plug into the bin. Discard both plugs.
B. Install the icemaker alignment brackets (Supplied with icemaker) to the dispenser (See Figure 2).
5. Install the Icemaker:
A. Install the icemaker alignment brackets (Supplied with icemaker) to the icemaker (See Figure 2).
B. Roll the Icemaker into the cabinet alongside the Dispenser.
C. Level and align the icemaker to the dispenser using the four level adjustment bolts located on the low-
er front of the Icemaker.
D. Install the locking bolt on the lower front of the icemaker.
E. Connect drain, power and water.
6. Install transport tube:
A. Insert the ice transport tube through the bin into the transport elbow on the Icemaker. (Note: The ice-
maker is equipped with a safety switch located at the base of the elbow, this switch will prevent the
icemaker from running if the elbow is not properly installed).
B. Align the nylon lock screw on the elbow with the recess on the tube. Install lock screw.
7. Connect bin thermostat:
A. Locate bin thermostat cable supplied with the icemaker (Black cable) and connect to electrical box on
the UC700 and the receptacle on the side of the dispenser.
