•
Properly adjust the air flow with the slides
on the front and rear of the ceiling
assembly. Supply louvers are provided on
the face of the ceiling assembly for
additional control of air flow.
•
Never obstruct the air flow to the ceiling
assembly.
•
Do not spray water or any cleaning fluid in
to the ceiling assembly. The ceiling
assembly should be cleaned with a damp
cloth.
•
Do not put any object, including your hands
into the openings of the ceiling assembly.
Reverse Cycle Operation
•
Operation of the reverse cycle in ideal
environmental conditions may allow the unit
to run in temperatures as low as 4 to 5
Celsius.
•
However operation of the reverse cycle in
cold environments combined with high
humidity/precipitation can result in the unit
entering a defrost cycle to alleviate icing of
the outdoor coil. This can happen at
temperatures as high as 5 to 7.5 Celsius.
•
At temperatures lower than those listed
above, the unit may enter a defrost cycle in
order to allow the unit to continue to
operate. At the end of this cycle, the indoor
blower is shut off to minimize any cold air
from entering the coach and the reversing
valve of the Heat Pump is unenergized,
shifting the unit back into A/C mode thawing
the outdoor coil to remove frost or ice that
may have formed.
This will take approximately 3 minutes, after
which the reversing valve is re-energized
and the unit will begin to operate in reverse
cycle again. This defrost cycle may allow
the unit to run at temperatures as low as 0
to 1 Celsius. (For more information on the
operation of the defrost cycle, refer to the
Service Manual.)
iii. ADJUSTING THE AIR FLOW
The conditioned air is distributed through the
ceiling assembly. Slides on the front and rear
of the ceiling assembly can be moved to
throttle the air flow to the front and rear. The
round supply air louvers can be adjusted to
direct air flow from the ceiling assembly. The
louvers can be opened and closed to adjust
air flow and also spin 360 degrees allowing
air flow to be directed where desired. (Use of
the supply louvers in the heating mode is
suggested to keep air from stratifying in the
coach.)
iv. HAND HELD CONTROLLER
The remote controller controls the operation
of the heat pump with an infrared signal to a
sensor on the ceiling assembly. For the best
reception, the remote should be pointing at
the ceiling assembly when changing the set
points and configuring the heat pump.
Note: Should the remote be lost, the heat
pump can be controlled by the buttons
provided on the ceiling assembly.
