REFRIGERATOR
(Model 70X)
The refrigerator in your coach can operate
from either of three energy sources available to
the motorhome:
•
120-Volt AC Electric
•
12-Volt DC Electric
•
Propane Gas
NOTE: The 12V DC operation is only
operational while the engine is running.
To be able to use all energy sources, the
refrigerator does not have a compressor like
household refrigerators. Instead, it uses an
ammonia-water solution for cooling. Basically,
ammonia vapor is distilled from the solution by
heat produced from either propane gas flame or
electrical heat element. The ammonia vapor is
then carried to the finned condenser where it
liquefies. The liquid then flows to an evaporator
where it creates cooling by evaporation. The
ammonia circulates back into the water solution
and the cooling cycle continues.
Leveling
Before operating the refrigerator when the
motorhome is stationary, place a small level on
the bottom of the refrigerator and make certain
the unit is level. If over 1/2 of the bubble is inside
the circle in any direction, the coach is level
enough for continuous operation of the
refrigerator while parked.
Normal vehicle leveling to provide comfort
for the occupants is satisfactory for refrigerator
operation.
Basic Operation
Switch on the Refrigerator
•
Push and Hold the on/off switch for 1 second.
A light in the on/off switch will turn green.
Refrigerator Operating Controls
(Located inside refrigerator door)
• 1 = Power On/Energy Selector Switch
• 2 = Temperature Controller
• 3 = Battery Igniter (Gas)
• 4 = Flame Indicator (Galvanometer)
NOTICE
To prevent permanent damage to the
refrigerator cooling unit, turn the
refrigerator off if the vehicle will be parked
on an incline of over 3
side-to-side or 6
front-to-rear (such as steep driveways or
parking lots, etc.) for more than one hour.
Place bubble level in bottom of refrigerator
Bubble must be at least 1/2 inside circle
