ARE A RE Q UI RE M E NTS

The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location.

The ice machine may be built into a cabinet, however the location must allow removal of the ice machine for cleaning and servicing. Service diagnostics are performed from the top of the ice machine.

The location must be free of airborne and other contaminants.

Do not place the unit within 18" (457) of a trash compactor or trash/recycling container.

The air temperature must be at least 50°F (10°C), but must not exceed 100°F (38°C) for models UC-15I and UC-15IP and 110°F (43°C) for models UC-15IO and UC-15IPO.

The location must not be near heat-generat- ing equipment.

The location must not obstruct air flow through the kickplate (airflow is in and out the front of the ice machine).

The location must allow enough clearance for water, drain and electrical connections at the rear of the ice machine.

Models UC-15IO and UC-15IPO may be installed outside.

The ice machine must be protected if it will be subjected to ambient temperatures below 32°F (0°C). Component failure caused by exposure to freezing temperatures is not covered by the warranty. See page 27.

Before moving the ice machine in place, be sure the finished opening dimensions, electrical and plumbing locations are accurate. Refer to pages 7–11.

Be sure your plumber, electrician and cabinet installer have this information before finishing work is completed.

Models UC-15I and UC-15IO are gravity drain models that require a drain tube that is pitched down from the outlet at the back of the unit to the sanitary sewer connection. Models UC-15IP and UC-15IPO have a built in drain pump that will pump water up to a drain point, such as a nearby sink. Refer to specifications on pages 8–9.

IMPORTANT NOTE: If the ice machine is installed in a corner, the door swing may be limited due to handle contact with the wall or cabinet face.

IMPORTANT NOTE: The floor under the

ice machine must be at the same level as the surrounding finished floor.

IMPORTANT NOTE: When you move the unit using a hand truck or dolly, position the dolly on the side of the unit and secure the door so it does not open while transporting the unit.

Any finished flooring should be protected with appropriate material to avoid any damage from moving the unit.

ELE CTR IC AL REQ UI RE ME NTS

Prepare electrical circuit before installation of your ice machine. Installation requires a grounded (three-prong), polarized receptacle with a separate fuse/circuit breaker in an electrical service box.

V OLTA GE

Do not use an extension cord or twoprong adapter. Electrical ground is required on this appliance. Do not remove the power supply cord ground prong.

All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed:

The ice machine must be grounded.

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

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

The minimum wire size is #14 for less than 100 feet (30.5 m) or #12 for more than 100 feet (30.5 m) to 200 feet (61 m) (solid copper conductor only). The recommended breaker is 15 amp. Local or state electrical code, length of run or materials used, can increase the minimum wire gauge required. A qualified electrician must determine the proper wire size, although #14 is the minimum size allowed.

Dimensions in parentheses are in millimeters unless otherwise specified.

IMPORTANT NOTE: Observe correct polarity of incoming line voltage.

Incorrect polarity can lead to erratic ice machine operation and a safety issue.

M I NI MUM CI RCU IT RE QU IR EM E N T

The minimum circuit requirement is used to help select the wire size of the electrical supply. (Minimum circuit requirement is not the ice machine’s running amp load.)

Prepare water supply line and drain before installation of your ice machine. Installation requires a minimum 1/4" ID copper cold water line and compression fitting (not supplied). Models UC-15I and UC-15IO are supplied with a drain hose for gravity draining. The optional drain pump or pump models UC-15IP and UC-15IPO must be purchased if a gravity drain is not possible. Both drain methods require routing to an open site drain. Do not connect directly to drain line as bacteria from drain line may contaminate the ice machine.

The included water filter is designed to inhibit scale formation, filter sediment, and remove chlorine odor and taste. The life expectancy of the water filter is 6 months during normal usage. The ice machine control board will monitor water usage and indicate when replacement is required.

WA T E R I NLE T LI NE S

Follow these guidelines to install water inlet lines:

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 (80 psi–551.5 kPA), obtain a water pressure regulator from your local plumbing contractor.

Install a water shut-off valve for the ice making water lines.

Insulate the water inlet line to prevent condensation.

DR AI N CO N NE CTI O NS

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 11/2" 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.

Drain pump discharge line must terminate at an open site drain.

Maximum rise – 12 feet (3.7 m)

Maximum run – 100 feet (30.5 m)

NOTE: If air temperature is less than 60°F (16°C), water temperature must be equal to or greater than 50°F (10°C).

IMPORTANT NOTE: Although the ice machine has been designed to be serviced in place, in some cases it may be necessary to pull the unit out for service. For that reason do not restrict access to the unit at the front, top and bottom.

If a floor is to be installed after the ice machine, shims the thickness of the floor should be installed under the unit to keep the ice machine level with the floor. Also, allow 1/8" (3) clearance on each side of the unit for protruding screw heads.

Installations on a slab: Use a Model UC-15IPO or UC-15IP, with built-in drain pump and pump the water to the point of drainage. Drain pump models will pump 12 feet (3.7 m) high.

Installations over a crawl space or basement: If there is not enough room behind the ice machine for a drain/waste water receptacle, the drain will have to be below the floor.

Dimensions in parentheses are in millimeters unless otherwise specified.
