SECTION 4: MAINTENANCE
Annually
WARNING:
Before cleaning or servicing, disconnect all power supplies.
To keep your Aqua-Hot running smoothly, it is ideal to have the Diesel-Burner
tuned-up annually. A tune-up should consist of a new Fuel Nozzle and Fuel
Filter, along with a thorough cleaning of the Combustion Chamber, if
necessary (reference Figure 5). To ensure maximum Diesel-Burner
performance, always use the recommended Fuel Nozzle (i.e., 0.35 GPH) and
Fuel Filter (i.e., 10 Micron) when replacing these parts. Reference the Aqua-
Hot “Parts Manual” for spare parts information. If detailed replacement
instructions are needed, please reference the Aqua-Hot “Shop Manual” or
contact the Technical Support Department at 1-800-685-4298 for the nearest
Aqua-Hot Service Center.
CAUTION
:
DO NOT
operate the Diesel-Burner and/or the Electric Heating
Element(s) without the water and antifreeze solution in the Aqua-Hot’s Boiler
Tank. Failure to do so will cause
serious damage
to the Heater.

SECTION 5: WINTERIZATION
5.1 Domestic Hot Water System
The Aqua-Hot's Domestic Hot Water Heating System must be completely
drained of domestic water any time the heater is stored where freezing
temperatures may be experienced.
CAUTION
: Not winterizing your Aqua-Hot when freezing temperatures
are present
will result in serious damage
to the Aqua-Hot's Domestic
Hot Water Heating System.
NOTE:
The Aqua-Hot can still be used for interior zone heating even if the
domestic hot water system has been drained and winterized.
Please follow the instructions listed below when winterizing the Aqua-Hot’s
Domestic Hot Water Heating System:
A.
Completely drain the fresh water storage tank.
NOTE:
If your motorhome is equipped with appliances that use fresh
water (e.g., ice makers, water purifiers, etc.) follow the manufacturer's
recommendation for winterization.
B.
Disconnect the domestic water demand pump's suction line from the
fresh water storage tank.
