Cleaning and/or changing the filters:
Disengage the two 1/4-turn fasteners that secure the
1.
ceiling assembly grille to the ceiling assembly (See
Figure 2).
Lower the grille and filters from the ceiling assembly.
2.
Take filters out and either clean or exchange with
3.
other filters (See Figure 2).
If the vehicle is equipped with a flush mount ceiling

assembly, remove the four return air grill screws.
Remove filter from grill and either clean or
exchange with new filters.
If replacement filters are necessary, the filters can be
purchased from most RV Products Authorized Service Centers.
It is recommended that spare filters be carried with the RV at all
times to replace worn, torn or

Electrical - All electrical work and/or inspection
should be performed only by qualified service
personnel. Contact your nearest RV Products Service
Center if electrical problems should arise.
Check Points - Failure to start or to cool the air are

sometimes problems with air conditioning units.
The RV Products RV air conditioner is designed to
operate on 115 volt electrical power. If the
compressor on the air conditioner fails to start, check

deteriorated filters.

with your RV Products Service Center to determine
that the proper wire size is connected to the unit, the
proper circuit breakers are installed as protection
devices on the electrical circuit and the proper sized
extension cord is being used for the distance covered
from the utility outlet to the RV. The required minimum
wire size is #12 AWG for lengths up to 25 feet (larger
wire size for greater distances). Each air conditioning
unit must be protected with a 20 amp time delay fuse or
circuit breaker.
If the air conditioner continues to trip off the circuit
breakers, have an electrician check the starting
amperage and running amperage on the unit. If
the circuit breaker continues to trip off and the
electrical consumption is found to be normal, it will
require the replacement of the faulty circuit breaker.
If all electrical power to the air conditioner is normal
but neither the fan or the compressor will operate,
the connector plug located behind the ceiling
assembly control box should be checked to
determine whether it is faulty.
On the heating-cooling air conditioner models, if all
electrical power to the unit is normal and the fan
runs but you never get any heated air, then the
electrical plug to the heating unit should be checked
for a secure connection. If this does not correct the
malfunction, the heating thermostat or limit switch
may be faulty.
Mechanical Integrity - The air conditioner should be
C.
inspected periodically to be sure that the bolts which
secure the unit to the roof are tight and in good shape.
Also, an examination of the plastic shroud covering
the air conditioner on the top of the roof should be
made periodically. Be sure the four mounting screws
and washers are snug and holding the shroud to the
air conditioner. Also examine the shroud to be sure it
is not developing cracks or has suffered damage from
impact.
D.
Lubrication
DISCONNECT THE POWER SUPPLY TO THE UNIT
BEFORE SERVICING TO PREVENT A SHOCK HAZARD OR
POSSIBLE INJURY FROM MOVING PARTS.
The blower drive motor on some units may include oiling cups
at the top of the motor. There is no requirement to oil the
journals under normal operating conditions. However, if
lubrication to the unit is desired, use only SAE 20 non-
detergent type oil. DO NOT OVER OIL - three to four drops in
each oil hole once a year is sufficient.
