MAINTENANCE

PERIODIC CLEANING

Disconnect the power supply before cleaning the refrigerator.

Beginning with the initial installation, the interior surfaces of the cabinet should be periodically

wiped down with a solution of warm water and baking soda (two tablespoons in one quart of warm

water). This solution will remove any odors from spillage that has occurred. The exterior of the

cabinet should also be cleaned frequently with warm water and a mild liquid detergent. Caution: Do

not use an abrasive or alkaline solution. Do not wash any removable parts in a dishwasher.

Defrosting

CAUTION: Refrigerator-Freezer must be unplugged to avoid electrical hazard from power

source when defrosting the unit.

On upright models with a defrost drain (Figure 1), remove the drain plug on the interior floor of the

freezer by pulling straight out. To access the external drain tube on models with the base panel,

remove the two screws from the base panel. Locate the drain tube near the left center under the

freezer. Place a shallow pan under the drain tube. Defrost water will run out. Check the pan

occasionally to ensure that the drain water does not overflow. A ½ inch garden hose adapter cab be

used to drain the freezer directly into a floor drain. If the model used is not equipped with an

adapter, one can be purchased at most hardware stores. Replace the drain plug when defrosting

and cleaning are complete. If the drain is left unplugged, warm air may enter the freezer.
