Operating the Refrigerator Controls
Controls:
The refrigerator control panel [1] is located on the rear of the
refrigerator (See Art00954). Unlike refrigerators with electric
controls, this refrigerator will operate on one energy source,
independently of the others.
Energy selector ................................................................ 1
Gas control ....................................................................... 2
Piezo lighter ...................................................................... 3
3 Amp fuse ....................................................................... 4
20 Amp fuse ..................................................................... 5
The energy selector [1] changes the energy source of the
refrigerator between propane GAS, AC electric, and DC electric
(See Art00953).
A nonadjustable thermostat controls the AC and DC operation of
the refrigerator. The thermostat has a capillary sensor that is
attached to the cooling fin. The AC or DC electric heater
operates in response to the temperature of the cooling fin to
keep the refrigerator temperature constant.
The gas control [2] changes the amount of propane gas that
goes to the burner. This acts as the temperature control of the
refrigerator. When operating the refrigerator on GAS, you can
change the refrigerator temperature to the desired setting by
putting the gas control at any position between HIGH COOL and
LOW COOL. HIGH COOL is the coldest temperature setting.
NOTE: This is not an automatic gas control. It does not change
the flame from high fire to low fire as with other RV
refrigerators. If the cooling load changes, you must
manually change the gas control to maintain the same
temperature inside the refrigerator.
When the outside air temperature is below 50° F., the refrigerator
may have a tendency to freeze food. To reduce the tendency to
freeze food:
To decrease the amount of ice that forms on the cooling fins:
- Cover all liquids and moist foods.
- Let hot foods cool before putting them in the refrigerator.
- Do not open the door any longer than necessary.
- Turn the gas control to LOW COOL position.
- Keep the refrigerator full.
- Put foods that are more likely to freeze on the lower shelf.
The gas control has a gas safety valve built into it. As long as a
flame is present, the safety valve is open and allows propane
gas to flow to the burner. Any loss of flame (empty gas tank,
blow out, etc.) closes the safety valve and stops the flow of
propane gas.
The piezo lighter [3] makes a spark which ignites the flame at the
burner.
The 3 Amp fuse [4] protects the AC wiring of the refrigerator.
The 20 Amp fuse [5] (model 323) protects the DC wiring of the
refrigerator.
Ignition - propane gas operation:
WARNING: Do not us a match for ignition. An ignition
flashback can cause burns to the hand or face. If, in an
emergency, you must use a match for ignition of the
refrigerator, do not hold in the gas control for more than
five or ten seconds at a time and use the longest match
possible.
1. Open the lower intake vent to get access to the rear of the
refrigerator.
2. Open the valve at the propane gas storage tank.
3. Open the viewing window on the burner box .
4. Turn the energy selector switch [1] to the GAS position (See
Aet00953).
5. Turn the gas control [2] to the HIGH COOL position.
6. Push and hold in the gas control.
- In rapid succession, push the igniter [3] in several times.
- Look through the viewing window and make sure that
ignition occurred.
WARNING: Do not hold the gas control in for more than
30 seconds. If there is no flame in this time, wait at least
five minutes before you try ignition again. If you continue
to hold the gas control in, gas will collect in the burner
area. This could cause a fire or an explosion and result in
dangerous personal injury or death.
- Continue to hold the gas control in for about 15 seconds
only.
7. Turn the gas control to the amount of cooling that you wish.
8. Close the viewing window on the burner box.
