I.
Cleaning and/or changing the filters:
1.
Pull down on the grille tabs until they snap out of place to remove the grilles from 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 them with other filters (See Figure 2).
Note:
If replacement filters are necessary, the filters can be purchased from your local dealer or distributor.

Service Person
A.
Electrical – All electrical work and/or inspection should be performed only by qualified service
personnel. Contact your nearest Coast to Coast authorized Service Center if electrical problems should
arise.
B.
Check Points – Failure to start or to cool the air are sometimes problems with air conditioning units.
The Coleman-Mach RV air conditioner is designed to operate on 230-240 volt, 50 Hz electrical power.
If the compressor on the air conditioner fails to start, check with your Coast to Coast authorized 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.
If the air conditioner continues to trip the circuit breakers, have an electrician check the starting
amperage and running amperage on the unit. If the circuit breakers continue to trip 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 nor 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, even after momentarily removing power and waiting ten minutes
per Item IV (Heat Operation) above, 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 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.
