Over cooling drains your vehicle battery

When the ambient temperature is between 70°F (21°C)and 90°F, (32°C) keep the temperature setting at about 40°F (4°C) to avoid an excessive drain of the battery. When making ice, or storing frozen foods, change the temperature setting to about 25°F (-4°C).

Check the Battery Charge Level

If the DC voltage to the refrigerator/freezer is less than 10.7 volts, the cooling performance of the refrigerator/freezer will immediately decrease. Make sure that the battery is fully charged.

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/freezer is “ON” and the battery charging system is “OFF”. Charge the battery when the specific gravity reading is less than 1.200.

NOTE: Never use a battery charger or a rectifier, etc. instead of the cigarette light adapter to operate the refrigerator/freezer on DC power. These electrical devices cause high ripples or surge voltages which can damage the refrigerator/freezer.

Never use a commercial inverter or converter to operate the refrigerator/freezer on AC power. These electrical devices do not hold the constant frequency that is necessary for the refrigerator/freezer.

Only use a “quick charger” on the vehicle battery if the power switch is turned to “OFF”. If a “quick charger” is used on the battery while the power switch is “ON”, damage to the refrigerator/freezer can occur.

Cooling Unit Basics

The cooling unit of your Norcold refrigerator/freezer makes heat. This heat must be removed quickly and efficiently in order for the refrigerator/freezer to have its maximum cooling performance. When the refrigerator/freezer is in an enclosed space, the temperature within the space will rise quickly and will reduce the cooling performance of the refrigerator/freezer. Continued operation at high temperatures can damage the refrigerator/freezer compressor and other components.

A free flow of air (ventilation) through the refrigerator/freezer condenser coils and around the compressor is necessary for the refrigerator/freezer to operate correctly. While Norcold refrigerator/freezers are made to operate in more severe conditions than typical household refrigerator/freezers, you should not operate the refrigerator/freezer in high ambient temperatures. This will result in poor performance and possible food spoilage.
