If replacement filters are necessary, the filters can be
purchased from most RV Products Authorized Service
Centers or from RV Products directly. It is recommended
that spare filters be carried with the RV at all times to replace
worn, torn or deteriorated filters.
5.
Replace the filters and reinstall the ceiling shroud in
reverse order starting with Step 3.
6.
For ducted systems, remove the four screws holding
the return grille to access the filter.

Service Person
A.
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.
B.
Check Points - Failure to start or to cool the air is
sometimes a problem with air conditioning units.
The RV Products air conditioner is designed to
operate on 115 volt electrical power. If the
compressor fails to start, check with your RV
Products Service Center to determine that the proper
wire size is connected to the unit, the proper circuit
breakers are installed 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.
NOTE
If the air conditioner continues to trip off the circuit
breaker, have an electrician check the starting
amperage and running amperage on the unit. If the
circuit breaker continues to trip and 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 fan or compressor will operate, the
connector plug located behind the ceiling assembly
control box should be checked to determine if 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.
C.
Mechanical Integrity - The air conditioner should
be 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 that the
four mount screws are snug and holding the shroud
to the air conditioner. While examining these
screws, 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.
