Thermostatic Controls
The following is a brief overview of how best to use the thermostat (Figure 3-6).
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.
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 main valve and through the regulator, it is
converted into a gas and its pressure is reduced to a safe level for use within the
motor home.
A LP gas-distribution system distributes the gas to those appliances using such in
the motor home. The “heart” of this LP gas distribution system is the regulator
and that regulator should only be adjusted by a qualified service technician.
Most of the problems encountered in lighting the pilots of these appliances
are caused by regulator mis-adjustments.
The major component of the LP gas supply is a manifold pipe which runs lengthwise underneath the motor home floor.
From this manifold, the various gas appliances are connected by copper tubing with flared fittings so that connections
and disconnections can readily be made, as needed.
Should any of the secondary tubing develop a leak, either on the tubing proper or at the fittings; do not attempt to
splice any of these lines. Instead, have a qualified service technician run a new length of tubing to the appliance of
concern and then have that line leak-tested before placing it in normal operation. To remove, repair, or replace any
gas-operated appliance; always close the main gas valve at the LP tank—this measure will provide an additional
element of safety to prevent gas leakage and possible, subsequent explosion hazards.
However, if a gas leak is noted or suspected, turn “off” the main valve and keep the LP gas system “off” until that
system is inspected by a qualified service technician as soon as possible. Do not delay in addressing any possible gas
leaks with appropriate service because of the inherent hazards to safety.
