GAS OPERATION
REFRIGERATORS WITH PIEZO IGNITOR
(RM2452 & RM2453)
1. To start the refrigerator, turn knob "A" to the "GAS" position.
2. Turn the thermostat knob "B" one-quarter (1/4) of a turn from the "OFF" position.
3. Push button "C", push button "D" for the piezo ignitor several times to light the burner. This can be observed
on the flame indicator "E", on the refrigerator.
4. After the flame lights, continue to hold button "C" for an additional ten (10) seconds. Release the button "C" and
check the flame indicator "E" to make sure the burner does not go out. If the burner goes out, repeat the lighting
procedure.
5. To shut off the refrigerator, turn knob "A" to the "OFF" position.
REFRIGERATORS WITH AUTOMATIC REIGNITERS
(RM2552 AND RM2553)
1. To start the refrigerator, turn knob "A" to the "GAS" position.
2. Turn the thermostat knob "B" one-quarter (l/4) of a turn from the "OFF" position.
3. Push button "C" in until it bottoms out - and hold. When flame indicator "E" shows the flame is on, hold push
button "C" an additional 15 seconds. Release button "C". If the flame indicator "E" starts to move toward off,
repeat lighting procedure. Should flame blow out, the reigniter will automatically relight the flame.
NOTE: After changing an LP tank, or after a long shut-off period, the gas line is likely to be filled with air. You
may have to repeat the lighting procedure several times to purge the air out of the gas lines.
ELECTRIC OPERATION
Check to be sure the power cord is properly connected to the power supply. If the refrigerator is equipped for 12
volt DC operation, the tow vehicle or caravan engine should be running to prevent discharging the battery.
Turn knob "A" to the position marked "ELEC" for 120 volt AC operation or "12V" for 12 volt DC operation.
Turn the thermostat knob "9" one-quarter (l/4) of a turn from the "OFF" position.
To shut off the refrigerator, turn knob "A" to the "OFF" position.
THERMOSTAT
The refrigerator is equipped with a thermostat that can be adjusted by turning knob "9" to a different setting to maintain
the desired cabinet temperature.
"OFF" Setting of the Thermostat: In gas operation, the thermostat closes its main valve and the burner runs
continuously at the bypass rate or pilot. In electrical operation, the contacts in the thermostat are open and the
heating elements are off.
"MAX" Setting of the Thermostat: In gas operation, the thermostat allows the burner to remain on high flame
continuously. In electric operation, the heating element is "ON" continuously.
The thermostat can be adjusted between "MAX" and "OFF" to obtain the desired cabinet temperature. The closer
the knob is to "MAX", the colder the cabinet temperature. The closer the knob is to "OFF", the warmer the cabinet
temperature.
When the thermostat reaches the set temperature, it will cut the burner back to bypass or, in electric operation, shut
off the heating element.
The setting of the thermostat is not critical, but we recommend it be adjusted to maintain a dry frost on the cooling fins.
Adjust the thermostat knob closer to "MAX" when the outside temperature becomes warm.
