Dometic RM1350 - Turning off the Refrigerator; Refrigerator Operation

NOTE: Do not continue to reset GAS operation if the LP
is ashing in the display after several tries. LP ashing
(message alternates between LP and the temperature)
indicates gas operation lockout (Flame Failure).
MODES OF OPERATION - AUTO AND GAS
AUTO MODE
When the refrigerator is in AUTO mode, it automatically
uses the most efcient energy source that is available
for operation. Should a more efcient energy source be-
come available during operation, the refrigerator controls
change from the current energy source to the more ef-
cient energy source as follows:
1. AC operation (if 120V AC is available). AC operation
is only possible in AUTO mode.
2. GAS operation (if 120V AC is not available).
Before starting the refrigerator:
• Check that all manual gas valves are in the on posi
tion.
• Make sure that a continuous 12V DC supply is avail
able for the electronic control to function.
To start the refrigerator:
1. Press the ON/OFF button.
2. Select operation mode:
• AUTO mode ( AC and GAS )
Press the AUTO/GAS mode selector button
( if not already on ).
• GAS mode ( gas operation only ).
Press the AUTO/GAS mode selector button to turn off
the AUTO mode (if not already off).
GAS MODE (manual LP gas operation)
When AUTO mode is turned off, the refrigerator uses
GAS as energy source - even if AC is available.
Startup
The thermostat has 5 settings where 1 indicates the warm-
est and 5 the coldest temperature setting. Press the but-
ton repeatedly until the desired setting, e.g. 3, is shown in
the LED display. This value is shown for about 5 seconds
and then the temperature is displayed once again.
Adjusting The Thermostat
Turning Off The Refrigerator
The refrigerator may be shut off while in any mode of op-
eration by pressing the main power ON/OFF button (OFF
position). This shuts off all DC power to the refrigerator,
including the interior light. If the refrigerator will not be in
operation for a period of weeks, it should be emptied, de-
frosted, cleaned and the doors left ajar and leveled.
Description Of Operating Modes
Auto Mode
When operating in the AUTO mode, the AUTO mode indi-
cator dot is lit. The control system will automatically select
between AC and GAS operation with AC having priority
over GAS. If the control system is operating with AC en-
ergy and it then becomes unavailable, the system will au-
tomatically switch to GAS. As soon as AC becomes avail-
able, the control will switch back to AC operation again.
Gas operation (when 120 volts AC is not available). The
control system will activate the ignition system and will
make three attempts to light the burner for a period of
approximately 45 seconds with two minutes rest (purge)
interval. If unsuccessful, LP will be ashing (the message
alternates between LP and the temperature) in the dis-
play. To restart an ignition attempt with LP ashing in the
display: turn unit off wait a few seconds and turn back on.
The control system will attempt a new ignition sequence.
If 120 volts AC becomes available while LP is ashing, the
refrigerator will operate on AC but the LP ashing will not
turn off until the main power ON/OFF button is pressed to
the OFF then ON position.
1.2 Refrigerator Operation
Before starting the refrigerator, check that all the manual
gas valves are in the ON position. DO NOT forget the
manual shutoff valve on the rear of the refrigerator. This
refrigerator is equipped with a control system, which can
be set to automatically select either 120 volt AC or LP gas
operation (AUTO mode), or if desired LP gas only (GAS
mode).
When operating in the GAS mode, the AUTO indication dot
is off and the LP indication dot is lit. This mode provides
LP gas operation only. The control system will activate the
ignition system and will make three attempts to light the
burner for a period of approximately 45 sec onds with two
minute (purge) intervals after each trial. If unsuccessful,
the display will ash LP. To restart GAS operation, press
the main power ON/OFF button to the OFF and then ON
position. The control system will at tempt a new ignition
sequence. If the refrigerator has not been used for a long
time or the LP tanks have just been relled, air may be
trapped in the supply lines. Purging the air from the lines
may require resetting the main power ON/OFF button
three or four times. If repeated attempts fail to start the LP
gas operation, check to make sure that the LP gas supply
tanks are not empty and the manual shutoff valves in the
lines are turned on.
