unless these switches are left on for long periods of
time on a battery with no means of recharging.
During AC operation, 12 volt DC is required to oper-
ate the interior light, humidity heater, the mode dis-
play, and electronic thermostat.
On 3-Way Models, the DC operation draws approxi-
mately 14.5 amps at 12 volts or 16 amps at 14 volts.
The DC voltage should be checked while operating
in the DC mode. The voltage at the refrigerator
should never drop below 11.5 volts.
Battery drain should also be considered during
times when the refrigerator is stored, defrosted, or
occasions when the door is left open. The interior
light will draw 600 milliamps and the humidity heater,
if left on, draws 240 milliamps for a possible current
draw of 840 milliamps (.84 amps). In this case, the
NORMAL-STORAGE-HIGH HUMIDITY switch should
be set to the "STORAGE" position (See section on
"High Humidity - Storage").
Except for DC operation (3-Way Models) it is evi-
dent that the 12 volt demand is quite low; neverthe-
less, the refrigerator should not be operated for long
periods of time from a battery only, without a means
of recharge (through alternator or converter).
The Freezer Compartment
Door Sealing
To maintain cooling efficiency and prevent exces-
sive frost build-up, the doors must seal completely
around the entire length of the door gasket. Frequent
frost build-up or reduced cooling are indications of air
leaks. To check for complete door sealing, lay a long
strip of paper (or a dollar bill) across the flange,
against which the gasket seals; then close the door.
A frictional drag should be felt upon withdrawing the
paper. Repeat in several places all around the door.
If the paper feels loose, the gasket is not sealing.
Contact your dealer or Service Center.

Cleaning the Refrigerator
It is important to keep the cabinet clean to minimize
the possibility of food odor. The best time to clean
the cabinet is after defrosting the refrigerator. Re-
