DESCRIPTION OF
OPERATING
MODES
THERMOSTAT
The
thermostat on the refrigerator
controls
both the gas
and
electric
operation, thereby eliminating the necessity
of resetting each time a different energy source is em-
ployed.
After the
initial
start-up, the thermostat should be moved
from ‘COLDEST’ to the desired temperature setting,
usually about mid setting.
AUTO MODE
When operating in the AUTO mode, the AUTO mode
indicator lamp (D)
will
illuminate. The control system
will
automatically select between AC and GAS operation
wlth AC having priority over GAS. Either the AC indicator
lamp
(B)
or the GAS indicator lamp (C) will illuminate
depending on the energy source selected by the control
system. If the control system is operating with AC energy
and it then becomes unavailable
,
the system
will
auto-
matically switch to GAS. As soon as AC becomes avail-
able again the control
will
switch back to AC regardless
of the status of GAS
operation.
GAS
MODE
When operating in the GAS mode the AUTO mode
indicator lamp (D) will be off and the GAS mode indicator
lamp (C)
will
be illuminated. This mode provides LP gas
operation only. The control system will activate the igni-
tion system and will attempt to light the burner for a
period of approximately 45 seconds. If unsuccessful, the
CHECK indicator lamp
(E)
will illuminate and the GAS
mode indicator lamp (C)
will
turn off.
To restart GAS operation, press the main power
ON/OFF button (1) to the OFF and then ON position. The
control
system will attempt a new
45
second
ignition
sequence.
If
the refrigerator has not been used for a tong time or
the LP tanks have just been refilled, air may. be trapped
in the supply lines. To purge the air from the lines may
require resetting the main power ON/OFF button (1)
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 all manual shutoff valves
in the lines are open. If the problem
is
still not corrected,
contact a service center for assistance.
If
the control
is
switched to AC or DC
(3-way
models
only) operation while the CHECK indicator lamp is on,
it
will
function properly, but the CHECK
lndicator
lamp
will
not go off until the main power ON/OFF button is pressed
to the OFF then ON position.

DC.MODE
(3-way
models only)
When operating In the DC
mode
the
DC mode indicator
tamp
(A)
will be illuminated. All other mode lamps will be
off. The DC mode overrides all other operating modes.
If one of the other operating modes is desired, the DC
selector button (2) must be pressed to turn OFF the DC
lamp (A).
IMPORTANT:
To
prevent the
refrigerator
from being left on and
draining the battery
when
the
vehicle’s
engine
Is not
running and charging the battery. It It recommended
that an automatk
cut-out relay be
Installed
between
the battery
and the refrigerator toggle
switch
so that
the refrigerator
will
not draw current when the
lgni-
tion of the vehicle
is
switched off. Alternatively, a
suitable plug and
receptacle should be installed In
the 12 Volt supply line, so
that
the refrigerator
can
be
disconnected from the supply, as
necessary.
LIMP
MODE OF OPERATION
This
control
system contains a feature where It
will
continue to operate the cooling system in the event of a
failure of
a
major operating component.
Two
different
modes of operation can occur in this category.
If for some reason the display module becomes non
functional,
the control system
will
revert to full automatic
operation selecting the best energy source
available
with AC, DC (3-way only) and GAS priority. The temper-
ature of the refrigerator will be maintained at the MID
position within normal temperature tolerances. The pow-
er module
will
continually attempt to reestablish oper-
ation of the display module.
The second limp mode of operation will
execute
when a
failure of the temperature sensing device or associated
electronic
circuitry
occurs. If thls should occur, the con-
trol system
will
operate on the energy source selected
via the control panel. The cooling
unit
will
run contin-
uously on the selected energy source. The refrigerator
will continue to operate in this mode Indefinitely or until
a new sensor is installed and the system
is
reset.
