Refrigerator Maintenance Checklist
If the refrigerator does not cool properly:
NOTICE
Have an authorized Norcold Service Center do these annual safety and maintenance checks:
1. Ensure the DC voltages are correct (See the "Electrical Current Necessary" section)
2. The wire connections must be clean, tight, and free of corrosion. If any of these items are not
correct:
- A voltage drop to the refrigerator will occur
- The voltage drop will decrease the cooling performance of the refrigerator
CAUTION
!
Refrigerator Care Checklist
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
!
Check The Battery Specific Gravity Reading
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 system is "OFF".
Charge the battery when the specific gravity reading is less than 1.200.
Norcold is not responsible for installation, adjustment, alteration, service,
or maintenance performed by anyone other than an authorized Norcold
Service Center.
Disconnect the positive(+) DC power supply wire from the battery before
you do a "fast charge" of the battery. Failure to disconnect the positive(+)
power supply wire from the battery during a "fast charge" can cause
damage to the refrigerator and/or other 12 volt DC appliances.
Only use a "quick charger" on the battery if the thermostat is turned to
"OFF".
