General Information

A.  The ability of the air conditioner to maintain the desired inside tempera-

ture depends on the heat gain of the RV.  Some preventative measures 

taken by the occupants of the RV can reduce the heat gain and improve 

the performance of the air conditioner. During extremely high outdoor 

temperatures, the heat gain of the vehicle may be reduced by:

1.  Parking the RV in a shaded area.

2.  Using window shades (blinds and/or curtains).

3.  Keeping windows and doors shut or minimizing usage. 

4.  Avoiding the use of heat producing appliances.

 

Operation on High Fan/Cooling mode will give optimum or maximum 

efficiency in high humidity or high outside temperatures. 

 

Starting the air conditioner early in the morning and giving it a "head 

start" on the expected high outdoor ambient will greatly improve its ability 

to maintain the desired indoor temperature. 

 

For a more permanent solution to high heat gain, accessories like Dometic 

outdoor patio and window awnings will reduce heat gain by removing 

the direct sun. They also add a nice area to enjoy company during the 

cool of the evening.

 

B.  The manufacturer of this air conditioner will not be responsible for dam-

age caused by condensed moisture on ceilings or other surfaces. Air 

contains moisture and this moisture tends to condense on cold surfaces. 

When air enters the RV, condensed moisture may appear on the ceiling, 

windows, metal parts, etc. During normal operation, this unit removes 

moisture from the air. Keeping doors and windows closed when this air 

conditioner is in operation will minimize condensed moisture on cold 

surfaces.

Maintenance

Air Filter - 

Periodic (a minimum of every 2 weeks of operation) remove the 

return air filter located behind the return air grill and wash the filter with soap 

and warm water. Let dry and then reinstall. 

NEVER 

run the air conditioner 

without the air filter in place. This may plug the unit evaporator coil with dirt 

and substantially degrade the performance of the unit over time.

Dometic Single Zone LCD thermostat:

 Clean the Single Zone LCD ther-

mostat with a moist soft cloth. 

DO NOT

 spray water directly on the Single 

Zone LCD thermostat. 

DO NOT 

use solvents for cleaning.
