ABSORPTION COOLING SYSTEM
f7\
When turning on the refrigerator, you should
ad-
N/
just the thermostat (excludes RM2351,
RM2451,
RM2551
,
DM2652
&
DM2852
-
not adjustable) to
the coldest temperature setting. The cooling cycle
may require
an
extended running time before cool-
ing effect
is observed.
LEVELING THE REFRIGERATOR
Leveling is one of the
requirements
for proper gperation
with absorption refrigerators.
To
ensure proper leveling the
vehicle
needs
to be
leveled
so it is
comfortable to live
in
(no noticeable sloping
of
floor
or walls).
Any
time the vehicle is
parked
for several
hours
with
the
refrigerator operating, the vehicle should be leveled to al-
low proper cooling.
When the
vehicle
is moving, the leveling is not critical, as
the rolling and pitching movement of the vehicle
will pass
to
either side
of
level, keeping the liquid ammonia
from
accumulating
in
the evaporator tubing.
PURGING
AIR
FROM THE LINES
lf the refrigerator has not been used for a
long time
-
or -
the
LP
tanks
have
just
been refilled, air may
be trapped
in
the supply lines. To purge
the air from the lines, turn the
refrigerator off and on by pressing the ON/OFF button. lf
the
flame
is not
lit
within 45
seconds, turn
the
refrigerator
off and back on
again. This procedure can
be
repeated
3
to
4
times.
lf
repeated attempts
fail to
start the
LP
gas opera-
tion, check
to
make sure that
the
LP
gas supply tanks are
not empty and that all
manual
shutoff valves in the
lines
are open. lf the
problem persists,
turn the
refrigerator
off
and
take
it
to
a Service Center.
WHEN THE
REFRIGERATOR
IN USE
NOT
Any
absorption refrigerator that
is
to
be
taken out of serv-
ice for an extended period of time
should
be turned
off.
/A
lt is important
that you do
not leave the refrigerator
V/
to
run idle and/or unattended for days or weeks.
AUTOMATIC ENERGY

automatic energy
se-
lector
system. The

the refrigerator automatically selects the most suitable en-
ergy source available, either
120 VAC or
LP
gas operation.
The system can be set by the user to be fully
automatic
(AUTO mode is
selected) or
to
operate on
LP gas
only

On 3-way models, the control system can manually
be
set
to
DC mode (DC

all
other operating
modes.
