Monthly:
Check the Aqua-Hot's 70/30 solution of water and antifreeze to ensure its
proper level. Visually inspect the coolant level in Aqua-Hot's expansion tank
when the Aqua-Hot is at operating temperature. Adding solution to the
expansion tank when the unit is cold will result in a solution overflow when
the Aqua-Hot attains normal operating temperature. The expansion tank is
located behind the fuel door.
Annually:
Have the Aqua-Hot tuned up yearly. A tune up consists of a fuel nozzle and
fuel filter replacement, as well as a thorough cleaning of the combustion
chamber. This simple tune up will keep the Aqua-Hot running smoothly
throughout the year, as well as allow service personnel to inspect for additional
wear of other components. Signs that the Aqua-Hot may need servicing are
continuous white exhaust smoke or poor ignition start up. When in operation,
the Aqua-Hot should have a smooth, high-pitched whine. Loud growls or other
abnormal noises indicate service or repair is required.
CAUTION: Before cleaning or servicing disconnect all power
supplies.
For more details about the Aqua-Hot system, see the Owner's
Information Packet.
During cold weather, locate the bay thermostat
next to the Aqua-Hot. This thermostat controls
the heat exchanger for holding tank bay heat.
Adjust the thermostat to 40 to 50° F. This will
help prevent freezing of the water system.
NOTE: Turn the Aqua-Hot ON when
heating the bay.
