Cleaning
A good time to clean the refrigerator is just after you defrost it.
Clean the inside of the refrigerator as often as necessary to avoid food odors:
- Remove all food from the refrigerator.
NOTE: Do not use abrasive cleaners, chemicals, or scouring pads because they can
damage the inside of the refrigerator.
- Wash the inside of the refrigerator and the door gasket with a solution of liquid dish
detergent and warm water.
- Rinse with clean water and dry.
- After cleaning, put a thin coating of petroleum jelly on the hinge side of the gasket to
keep it soft and to prevent it from rolling.
Battery Maintenance
Over cooling drains your battery
- When the ambient temperature is between 70° and 90° F, keep the thermostat at the “3“
position to avoid an excessive drain of the battery. When making ice, or storing frozen
foods, turn the thermostat to the coldest setting “5“.
Maintain the battery
If the charge of your battery is not sufficient, the cooling performance of your refrigerator
decreases.
CAUTION: Only use a “quick charger” on the battery if the thermostat is turned to
“OFF”.
Check the Battery charge Level
A fully charged battery will have a specific gravity reading of between 1.260 and 1.280. The
battery voltage is best indicated when the refrigerator is “ON” and the battery charging sys-
tem is “OFF”. Charge the battery when the specific gravity reading is less than 1.200.
