HEATING & AIR CONDITIONING
AQUA-HOT HEATING SYSTEM (OPTIONAL)
The Phaeton may include an optional Aqua-Hot heating sys-
tem (Figure 3-1) that provides a continuous, on-demand sup-
ply of domestic hot water, as well as interior zone heating when
and where it is needed.
To activate the Aqua-Hot heating system, there is a switch on
the wall panel located near the bedroom.By activating this
switch, a supply of hot water as well as interior heat can be
provided. The heating feature will be controlled by the ther-
mostat mounted on the wall. The label marked with an electric
bolt represents the electric mode, while the flame represents
the gas, or in this case, the diesel mode.
NOTE: The use of the electric mode provides only a short, lim-
ited amount of hot water usage.
If interior heat and hot water are both needed at the same time,
the hot water will take precedence over the interior heat, caus-
ing the interior heat to shut down and turn off until the water
flow is turned off from water sources.
The surge tank (Figure 3-2), which is located in the basement,
should be routinely inspected to make sure the anti-freeze fill line stays in the acceptable zone. If
the anti-freeze becomes low, you must add
the recommended anti-freeze stated in the
Aqua-Hot’s owner’s manual.
If anti-freeze is totally depleted from the
surge tank, a switch will be released inside
the main Aqua-Hot tank, disabling the sys-
tem from operating. Anti-freeze will then
have to be added to the tank to reactivate
the switch and allow the system to operate.
If batteries become discharged and the
Aqua-Hot system is activated, the system
will automatically shut down before bat-
teries are totally discharged. Once power is
restored to the batteries, the system must be
reset by depressing the reset button on the
black panel of the surge tank (Figure 3-3).
