Adjusting The Air Flow; Hand Held Controller - RV Products AIRXCEL Coleman-Mach 47000 Serie Instrucciones Operativas Y De Mantenimiento

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 compressor being turned off to prevent 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 prevent 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.

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 adjust the air flow to the front and rear. The round supply louvers can be adjusted
to direct air flow from the ceiling assembly. The louvers can be opened and closed to adjust airflow and
also spin 360 degrees allowing air flow to be directed where desired. (Use of the supply louvers in heating
mode is suggested to keep air from stratifying in the coach.)

Hand Held Controller

The remote controller controls the operation of the air conditioner or 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 set points and configuring the air conditioner or heat pump.
Note: Should the remote be lost, the air conditioner or heat pump can be controlled by buttons on the
ceiling assembly.
