is not at fault; simply reset your breakers and/or replace your fuses. Should such conditions continue,
one may wish to turn reduce the electrical load (in this case, turn “off” the air conditioning system for
awhile) or start the electrical generator.
To cool the motor home, the thermostat inside the Phaeton is used—this is
the same thermostat which controls the furnace functions (described earlier).
The air-conditioned, cooled air is emitted through the vents which are
located in the roof throughout the entire coach. The discharge and return air
vents run parallel, front to back, on the ceiling. Note that the return vents are
similar to the air conditioning vents. This system allows even distribution for
the returns instead of forcing an excess amount of return air through two
smaller openings. The even return system takes more of the hot air from the
motor home, thereby providing cooler air throughout the unit. The air
conditioning vents that are mounted on the ceiling are round vent filters
(Figure 3-2) that need to be periodically checked for dust accumulation. When dust has accumulated on
the filters, remove them and wash in a mild detergent and warm water.
Thermostatic Controls
The following is a brief overview of how best to use the thermostat (Figure 3-3). For more detailed
instructions, please consult the thermostat literature in the Owner’s Information Package.
1. Turn “on” the power switch on the thermostat(s).
2. Use the Mode switch to select the desired function (e.g.,
COOL, OFF, HEAT). Note: In the “COOL” mode there
will be a delay of several minutes before the refrigerant in
the air-conditioning system begins to cool the motor home,
as the compressor is on a time-delay circuit and it must also
cool the ductwork to the vents first.
3. Select the Fan Mode operation (AUTO or ON) and the Fan
Speed operation (LO or HI) to select fan speed desired.
4. Press the Up and/or the Down buttons to set the desired
temperature for the motor home.
5. If your vehicle should contain more than one control zone, press the zone button to select the
desired zone and then repeat the procedures from Step 2 onwards for each control zone.
NOTE: If the thermostat is turned “off” or the thermostat loses power (i.e., power failure), the air-
conditioning system will resume operation at the last settings
programmed into it when electrical power is restored.
Liquid Propane (LP) Tank
The Phaeton is equipped with an ASME (American Society of
Mechanical Engineers)-approved LP tank (Figure 3-4) which is equipped
with an automatic pressure regulator. This tank contains liquid
petroleum fuel under high pressure. As this fuel passes through the
