Features

Starting the ice machine

This machine takes in room temperature air at the lower right front and forces warm air out the lower left front. Restricting the airflow or operating the machine in a hot or cold environment will adversely affect the ability of the ice machine to make ice.

When the door is opened, the control panel, ice making area and ice storage bin are visible. The scoop is located in a holder along the right side wall.

This is a gravity drain model that must have a building drain connection below the level of the drain tube at the back of the cabinet. A pump can be installed, which can force drain water up a maximum of 10 feet, allowing it to be located where a gravity drain isn't available. See Accessories on page 21 for more information on the drain pump.

Initial Start Up

  1. Turn on the water supply.
  2. Switch on the electrical power.
  3. Push and release the ON/OFF switch to start the machine. The ICE MAKING light next to the ON/OFF switch will glow white.

It will take about 10 minutes for the ice machine to begin dropping nugget ice into the storage bin. It is normal for that ice to melt and continue to melt but at a slower rate as the bin cools. It will take about 6-7 hours to fill up the ice storage bin. The storage bin holds about 20 Ibs of ice when full.

Discard the first bin full of ice.

INSTALLATION INSTRUCTIONS

ICE MACHINE LOCATION AND PREPARATION

This ice machine is designed to be used indoors, in a controlled environment or outdoors within certain limits.

It is made up of two major systems: the ice making system and the ice storage system. The ice making system is a continuous flow that makes ice when the ice level becomes low and stops when it is full.

The ice storage system is an insulated chest with a drain at the bottom for melting ice. It is not refrigerated, insuring that the bin contains fresh ice.

During ice making, nugget ice will drop into the bin at an irregular rate; sometimes there will be little ice falling while other times a group of nuggets will fall.

IMPORTANT: Never keep anything in the ice storage bin that is not ice. Objects like wine or beer bottles are not only unsanitary, but the labels can slip off and plug up the drain.

IMPORTANT: Never allow the machine to operate without regular cleaning. The machine will last longer if it is Kept clean. Regular cleaning should happen at least once per year, and preferably twice. Some water conditions will dictate even more frequent cleaning of the ice making section, and some carpets or pets will dictate more frequent cleaning of the condenser.

Specifications

The ice machine will operate adequately within the limits, but functions best in temperatures between 60°F and 80°F.

  • Minimum air temperature: 50°F (10°C)
  • Maximum air temperature: 100°F (38°C)
  • Minimum water temperature: 40°F (4.5°C)

Installation Notes

A drain pump is available for this ice machine. The drain pump kit number is UPK3 and is available at GEApplianceparts.com or by calling 877-959-8688. In Canada visit GEAppliances.ca or call 800.567.3344,

Built-In Installation: If a finished floor is to be installed in the area after the ice machine has been built in, shims the expected thickness of the floor should be installed under the unit to keep the machine level with the planned floor level.

NOTE: The water connection is at the back and adds a few inches to the cabinet depth.

Installation on a slab: You will need to install a drain pump to the appliance and pump the water to the point of drainage. See Accessories. Pumps will pump 1 story (10 feet) hight.

Installation over a crawl space or basement: Either a gravity drain or a pump may be used. For pump, see Accessories. If there is not enough room behind the machine for a drain/waste receptacle, the drain will have to be below the floor.

NOTE: When installed in a corner, the door swing may be limited due to handle contact with the wall or cabinet face.

A water supply is required. Water supplies vary in the degree of mineral content. High mineral content water will require more frequent maintenance. Water filtration may improve the taste of the ice as well as cut down on some of the mineral build up.

DOOR SWING

Moving the hinges allows the door to open from either the left or the right side. Change the swing BEFORE attaching the door panel.

To change:

1. Open the door. Remove 4 stainless steel screws opposite the hinge side on the front of the cabinet.

2. Remove innermost screw holding each hinge to the cabinet. Loosen the other screw.
