NOTE: While operating the refrigerator or other appliances on inverted power and the vehicle is in motion,
monitor the charging voltage of the chassis electrical system. This is usually done by reading the voltage gauge on
the dash display.
If the voltage is lower than normal, it usually means that the chassis charging system can not keep up with the
electrical demand from the batteries.
You may need to turn off some electrical appliances so that battery charging voltage remains at a normal level.
Other tips include:
• Since it takes more energy to cool down refrigerated contents than to maintain coolness, operate the
refrigerator on 120 volts AC or LP when stocking the refrigerator.
• When operating on 12 volts DC (via the inverter), minimize opening the refrigerator door.
• An empty refrigerator is not as energy efficient as one that is full. Keep your RV refrigerator well stocked
with items such as bottled water or other dense food items.

Effects of High Altitude on Propane Gas Operation
When you operate the refrigerator on propane gas at altitudes higher than 5,500 feet above sea level, you
may experience reduced cooling performance of the refrigerator. You may also experience burner outages. To
avoid these possible problems, the refrigerator manufacturer recommends that you operate the refrigerator
on 120 volts AC when at altitudes higher than 5,500 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 your refrigerator is equipped for low temperature operation, the refrigerator will operate in temperatures
down to 0° F. Check with your TMC dealer to determine if your refrigerator has been equipped for low
temperature operation.
Care and Maintenance
Your refrigerator is designed to 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.
• Defrost the refrigerator as necessary (see manufacturer’s instruction manual).
• Make sure the door seals are clean and sealing properly.
• Be aware of any cooling changes that are not due to weather conditions, motorhome leveling, or gas
control changes. Unexpected cooling changes may indicate service is required.
• Make sure the gas supply is propane (LP) ONLY and not butane or a propane/butane mixture.
• Occasionally observe the appearance of the propane flame (see manufacturer’s instruction manual).
Abnormal flame appearance may indicate service is required.
