Installation and Owner’s Manual 3Refrigerator Care ChecklistYour refrigerator will give you years of trouble free service if you do these simple checks every three to six months:- Make sure the air flow in the lower intake vent, through the refrigerator coils and condenser, and out the upper exhaust vent is notblocked or decreased.- Make sure the area behind the refrigerator is clear. Do not use the area behind the refrigerator for storage of anything, especiallygasoline and other flammable vapors and liquids.Effects of High Altitude on Propane Gas OperationWhen 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 feetabove sea level.Effects of Freezing Temperatures on Refrigerator OperationA gas absorption refrigerator is not designed to operate in freezing temperatures. If the refrigerator is not equipped for low temperatureoperation, 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 warmssufficiently.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 thecooling system of the refrigerator are not covered by the Norcold limited warranty. Please contact your local RV dealer for informationabout 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 therefrigerator installation or to the venting, are not covered by the Norcold limited warranty.DefrostingThe cooling fins of the refrigerator operate at below freezing temperature and will naturally form frost from humidity, which is alwayspresent in the air. The humidity inside the refrigerator increases:- with higher outside temperature and humidity.- with the storage of non-sealed fresh foods or warm foods.- with the amount of time that the door(s) are open.- with any air leakage into the refrigerator.Although the refrigerator is not frost -free, it is made to limit frost on the cooling fins. At regular intervals, the temperature control systemautomatically melts most of the frost from the cooling fins. The water from the cooling fins drains into a collection cup that is attached tothe back of the refrigerator. The heat of the cooling system evaporates the water from the collection cup.
