HEATING & AIR CONDITIONING
AQUA-HOT HEATING SYSTEM
Th
e Allegro Bus features an Aqua-Hot
heating system (Figure 3-1) that provides
a continuous, on-demand supply of do-
mestic hot water, as well as interior zone
heating when and where it is needed.
Both heating features are accompanied
by a unique VDC-powered diesel-
fi
red
burner and a VAC-powered electric heat-
ing element (120 VAC).
Th
ese two heat-
ing sources maintain the temperature of
the Aqua-Hot’s solution of water and an-
ti-freeze.
If interior heat and hot water are both need-
ed at the same time, the hot water will take
precedence over the interior heat, causing the interior heat to shut down and turn o
ff
until the water
fl
ow is turned o
ff
from water sources.
Th
e surge tank (Figure 3-2), which is located in the basement, should be routinely inspected to make
sure the anti-freeze
fi
ll 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 batter-
ies are totally discharged. Once power is re-
stored to the batteries, the system must be
reset by depressing the reset button on the
black panel of the surge tank (Figure 3-3).
For detailed operations on using the Aqua-
Hot Heating System, refer to the owner’s
manual in your Ti
ffi
n Owner’s Information Package.
