Effects of High Altitude on Propane Gas Operation

When you operate the refrigerator on propane gas at altitudes higher than 5500 feet above sea level:
- You may experience reduced cooling performance of the refrigerator.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that you operate the refrigerator on AC when at altitudes higher than 5500 feet
above sea level.

Effects of Freezing Temperatures on Refrigerator Operation

A gas absorption refrigerator is not designed to operate in freezing temperatures. If the refrigerator is not equipped for low temperature
operation, and if the cooling system of the refrigerator is exposed to temperatures of 32° F. or lower for an extended period of time,
the refrigerator operation may be disrupted. The refrigerator operation will resume when the cooling system of the refrigerator warms
sufficiently.
If the refrigerator is equipped for low temperature operation, the refrigerator will operate in temperatures down to 0° F.
Disrupted operation of the refrigerator, due to extended exposure to temperatures of 32° F. or lower, and any costs incurred to warm the
cooling system of the refrigerator are not covered by the Norcold limited warranty. Please contact your local RV dealer for information
about how to resume refrigerator operation or about how to equip your refrigerator for operation in freezing temperatures.
Do not change the installation or the venting of your refrigerator. Refrigerator failures, which are the result of changes to either the
refrigerator installation or to the venting, are not covered by the Norcold limited warranty.

Refrigerator Care Checklist

Your refrigerator will give you years of trouble free service if you do these simple checks every three to six months:
- Keep the food compartment and the freezer clean. See "Cleaning".
- Defrost the refrigerator as necessary. See "Defrosting".
- Make sure the door seals correctly. See "Door Sealing".
- Be aware of any cooling changes that are not because of weather, loading, or thermostat changes. If changes occur, contact your
dealer or service center.
- Make sure the gas supply is propane gas only and is not butane or a butane mixture.
- When in propane gas operation, examine the appearance of the flame. See "Gas Flame Inspection".
- Make sure the air flow in the lower intake vent, through the refrigerator coils and condenser, and out the upper exhaust vent is not
blocked or decreased.
- Make sure the area behind the refrigerator is clear. Do not use the area behind the refrigerator for storage of anything, especially
gasoline and other flammable vapors and liquids.
