Make sure the selector switch is in the "OFF" position.
1.
Turn on the 240 volt power supply to the vehicle.
2.
To check fan operation: Turn selector switch to
"LOW FAN", then to "HIGH FAN". Fan should
run continuously at low speed on "LOW FAN" and
continuously at high speed on "HIGH FAN". See
Figure 1.
3.
To check cooling operation, turn the selector switch
to "LOW COOL" and then to "HIGH COOL".
Compressor and fan should run at both positions.
Fan should run on low speed on "LOW COOL" and
on high speed on "HIGH COOL". See Figure 1.
For compressor operation, the room temperature
must be above the lowest thermostat setting
(approximately 58 degrees F). If the temperature is

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 air conditioner is designed to operate
on 240 volt electrical power.
If the compressor on the air conditioner 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
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 #14 AWG
for lengths up to 25 feet (larger wire size for greater
distances). Each air conditioning unit must be
protected with a time delay fuse or circuit breaker:
Series 6000 - 15 Amp
Series 7000 - 15 Amp
Series 8000 - 15 Amp

MAINTENANCE
C.
The air conditioner should be inspected periodically to be
sure that the bolts which secure the unit to the
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
snug and holding the shroud to the air conditioner. While

below this setting, the compressor will not start.
Also, in the cooling mode the thermostat controls
only the compressor operation.
To check a model with Elect-A-Heat, turn the
selector switch to "HEAT" and the thermostat to
"WARMER". Check the heat output.
NOTE
For heating, the thermostat is factory adjusted to
cycle "OFF" when the return air temperature is
between 80 and 85 degrees F. If the electric heat
does not come on, it is likely that the coach
temperature is over 80 degrees F.
To actuate the heater for operation checkout under
this condition, run the air conditioner for five to ten
minutes (to "cold-soak" the air distribution
chamber), then follow through with the heater
checkout.
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 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.
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.
