Cleaning and/or changing the filters:
1. Disengage the two 1/4 –turn fasteners that secure the
ceiling assembly grille to the ceiling assembly (See
Figure 2).
2. Lower the grille and filters from the ceiling assembly.
3. Take filters out and either clean or exchange with
other filters (See Figure 2).
4. If the vehicle is equipped with a flush mount ceiling
assembly, remove the four return air grille screws
(See Figure 3).
5. Remove filter from grille and either clean or
exchange with new filter.
If replacement filters are necessary, the filters can be
purchased from most Airxcel, Inc. Authorized Service
Centers. It is recommended that spare filters be carried with
the RV at all times to replace worn, torn or deteriorated filters.

II. Service Person
A. Electrical – All electrical work and/or inspection
should be performed only by qualified service
personnel. Contact your nearest Airxcel, Inc.
Service Center if electrical problems should arise.
B. Check Point – Failure to start or to cool the air are
sometimes problems with heat pump units. The
Coleman-Mach RV heat pump is designed to
operate on 115 volt electrical power. If the
NOTE
compressor on the heat pump fails to start, check
with your Airxcel, Inc. 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
heat pump unit must be protected with a 20 amp time
delay fuse or circuit breaker.
If the heat pump 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 heat pump 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 heat pump 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 heat pump 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 heat pump on the top of the roof
