3. Turn the thermostat knob G to setting 4.
When the refrigerator is equipped for 110 volts and 12 volt operation the
turning movement of the knob A should be made as follows:
In gas OFF position the knob is pressed and turned clockwise to the
12 volt position, If 110 volt operation is desired press once more and
continue the clockwise turning to the 110 volt position marked
LEVELING
In the boiler of the cooling unit, ammonia vapor is distilled from an ammonia-water
mixture and carried to the finned condenser where it liquefies. The liquid f

When the vehicle is stationary it must be leveled to be comfortable to live in. If
the refrigerator is properly installed, i.e. the ice-tray compartment shelf is
parallel with the floor, the refrigerator will operate properly, To check this, a
bubble level (see Fig. 73) is supplied with the refrigerator, The level should be
placed on the ice-tray compartment shelf and the
position of the bubble observed (if necessary,
with the aid of a small mirror), Adjust the position
of
the
vehicle so that the bubble is in the center
ring of the level.
When the vehicle is on tow, the continuous rolling and pitching movement

when the vehicle is temporarily parked, the sensitivity of the refrigerator should
be remembered,
1.
When the temperature control (thermostat) is set at a higher number, refrige-
rating effect will be increased, This
tend to lover the temperature in the
freezing compartment and in the food storage compartment.
the temperature control is set at a lower number, refrigerating effect will
be reduced.
the temperature control is set at mid-dial position, medium refrigerating
effect will be produced.
2.
The position of the temperature control should depend upon the refrigerator
load.
the food load is heavy, turn the temperature control to a higher
number .
higher setting of the temperature control will be required in summer
than in winter.
The setting of the temperature control determines the action of the thermostat
in relation to freezing compartment temperatures,
THE
CAPILWRY TUBE
On the fresh food evaporator is a sleeve in which the end
of the thermosta: capillary tubing must be inserted. Check
that the capillary tube is firmly in place, If the capillary
tube is not properly inserted in its sleeve

burner will operate continuously at maximum flame.
It will cause too low cabinet temperatures.
