below this setting. The air conditioner will
keep cycling the compressor ON and OFF
in this fashion until you change the
selector switch to another mode of
operation. During this time, both the air
recirculating system and the refrigerant
system will be in operation to provide you
with filtered dehumidified, cold air in the
volume you desire.
Operation of damper (Small lever)
When relative humidity conditions are high, set
air damper at either medium or high setting. In
high humidity conditions we do not
recommend operation of the air conditioner at
the full "Lo Air Volume" position, which may
cause excessive sweating at ceiling plate
location.
Operation during cooler nights (Cooling)
It is irrlportant when temperatures drop in the
evening or during the rlight below 75" F. that
the thermostat (Temperature Control) be set at
about midway between "COLDER" and
"WARMER". When the setting is at
"COLDEST" it may cause freezing or icing-up
of the cooling coil (Evaporator) and stop
cooling. During the heat of the day reset
temperature control to any desired cooling
position.
Note: Should icing-up have occurred it
IS
necessary to let the coil defrost before normal
operation is possible. Run unit on "Fan Only"
position. If increased or full air .flow
IS
observed,
the coil should be clear of ice.
To operate for heating:
1 . Set the selector switch (left hand knob as
you face the unit) to the "Heat" position.
The fan will automatically start circulating
air continuously.
2. Set the temperature control to the
temperature level that is the most
comfortable for you. The heater will
automatically turn on when the
temperature of the air entering the air
conditioner 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 the
temperature setting you have selected.
The air conditioner will keep cycling the
heat on and off in this fashion until you
change the selector switch to another
mode of operation.
Note: The trailer temperature must be
below 80°F. for the heater to operate.
3. You can regulate the air volume and
resulting air temperature change with the
lever and in conjunction with closing the
louvers partially. Fully open louvers will
throw the prewarmed air toward the back
and front for efficient circulation and faster
warm-up of the vehicle. Note: Although
the air temperature is lower the same
amount of heating capacity is produced,
regardless of louver position. Hottest air
IS
produced when lever is in full down
positon.
Note: Elect-A-Heat is intended to take
the chill out of the indoor air when the air is
a few degrees too cool for comfort. When
properly sized, the Elect-A-Heat is an
effective "chill chaser". It is not a
substitute for a furnace. In freezing
weather, it will not keep water and
holding tanks from freezing.
To operate for air recirculation only
1 . Set the selector switch to the "Fan Only"
positions on the left hand dial. The fan will
run continuously and filter the air without
either cooling or heating the air. To obtain a
lower or higher volume of circulating air,
simply lower or raise the air volume lever.
This will close or open the damper in the air
conditiorling unit to give you almost
unlimited control over the volume of air
being recirculated in your trailer.
Owner's Maintenance:
Cleaning and changing the filters.
The air filters are located in the interior ceiling
shroud and are accessible for changing and/or
cleaning as follows:
1 . Remove the two (2) screws from bottom of
the ceiling shroud.
2. Pull down on ceiling shroud at end
opposite the control knobs; filtes can then
be removed for changlng or cleaning.
3. Replace filters and "snap" ceiling plate
back into its original position and reinstall
screws.
Note: Make sure that supply wire and
thermostat cap tube are routed clear of the
spring "legs" to avoid snagging of these
items when ceiling plate is pulled down for
filter servicing.
