Operation - Airxcel ROUGHNECK Série Mode D'emploi Et Utilisation

Cooling (Refer to Figure 1) -
A. Turn the selector switch to the "LOW COOL" or
"HIGH COOL" position.
B. Rotate the thermostat (temperature control) switch to
the position that is the most comfortable to you. The
thermostat will turn the compressor on when the
temperature of the air entering the air conditioner
rises a few degrees above the setting you have
selected. When the temperature of the air entering the
air conditioner drops below the selected setting, the
thermostat will turn the compressor off. The
thermostat will continue to cycle the compressor on
and off in the above mentioned fashion until the
selector switch is turned to another mode of

operation.

C. Rotating the thermostat (temperature control) switch
to the "MAX COOL" position will bypass the
thermostatic control and lock the compressor in the
cooling mode for continuous cooling. During the use
of sensitive electronic equipment, the constant cool
feature may be used to prevent compressor cycling
from the thermostat. Discretion should be used, do
not leave in the constant cool mode if it is not
required (possible freeze up can occur).
D. Position the louvers to the desired direction the
discharge air is to flow.
Operation During Cooler Nights (Cooling Operation) -
It is important, when the outdoor temperature drops in the
evening and during the night to below 75 degrees F, that the
thermostat (temperature control) be set at a midpoint between
"Warmer" and "Cooler". If the setting is at "Cooler", the
cooling (evaporator) coil may become iced-up and stop
cooling. During the day when the temperatures have risen
above 75 degrees F, reset the thermostat switch to the desired
setting.
Should icing-up occur, it is necessary to let
the cooling (evaporator) coil defrost before
normal cooling operation is resumed. During
this time, operate the unit in the "HIGH FAN"
position with the system at maximum air flow.
When full air flow returns, the cooling coil
should be clear of ice.
III. OPERATION
NOTE
For Heating –
The heating assembly is intended to take the chill out of the
indoor air when the air is a few degrees too cool for comfort.
The heating assembly is an effective "chill chaser". It is not a
substitute for a furnace. Do not expect the heating coil on
your heater to glow. Because the fan draws in cold air and
forces it over the coil, the coil will not turn red. A hint of red
may occur where the moving air does not directly touch the
coil.
A. Turn the selector switch to the "LOW HEAT"
position. At "LOW HEAT", the fan operates on low
speed with heat output at maximum.
B. Rotate the thermostat (temperature control) switch to
the position that is the most comfortable to you. The
heater will automatically turn on when the
temperature of the air entering the air conditioning
unit drops below this setting a few degrees, and
automatically turns off when the temperature of the
air entering the air conditioner rises a few degrees
above this setting. The heater will continue to cycle
on and off in this fashion until the selector switch is
turned to another mode of operation.
C. Position the louvers to the desired direction the
discharge air is to flow.
Discharge air temperature can be controlled to some
extent by opening or closing the louvers.
When the louvers are closed, the warmest localized
discharge air is achieved. Fully opened louvers will
throw the warm discharge air to the back and front
of the vehicle for more efficient circulation and faster
warm-up. Although the air temperature is lower with
the louvers fully opened, the heating capacity is still
the same.
For Air Recirculation Only (Refer to Figure 1) –
A. Turn the selector switch to "LOW FAN" or for
maximum air flow, to "HIGH FAN".
B. Position the louvers to the desired direction the
discharge air is to flow.
When the selector switch is set to "LOW
FAN" or "HIGH FAN", neither heating or
cooling function occurs.
