4.1 Domestic Hot Water System
The Hydro-Hot's domestic hot water system must be completely drained of
domestic water any time the heater is stored where freezing temperatures
may be experienced.
NOTE: The Hydro-Hot can still be used for interior zone heating even if
the domestic hot water system has been drained and winterized.
CAUTION: Not winterizing your Hydro-Hot, when freezing temperatures
are present, will result in serious damage to the Hydro-Hot's domestic
hot water system.
Follow the instructions listed below when winterizing the Hydro-Hot’s
domestic water system:
A. Completely drain the fresh water storage tank.
NOTE: If your coach is equipped with appliances that use fresh water (i.e.
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.
C. Attach an adequate piece of hose onto the suction side of the domestic
water demand pump.
D. Place the opposite end of the hose into an adequate supply of FDA
approved RV-Antifreeze; approximately 2 gallons will be required.

Upkeep
3.1 Maintenance Schedule
Monthly
Check the Hydro-Hot's solution of water and antifreeze to ensure that it
is at the proper level. Do this by visually checking the coolant level in
the Hydro-Hot's Expansion Tank, Figure 1. This should be checked
only when the Hydro-Hot is at operating temperature, HOT.
Annually
CAUTION: Before cleaning or servicing, disconnect all power supplies.
It is ideal to have your Hydro-Hot tuned-up yearly. A tune-up should
consist of a Fuel Nozzle and Fuel Filter replacement and a thorough
cleaning of the Combustion Chamber, if necessary. This simple tune-up
will keep your Hydro-Hot running smoothly throughout the year. This
annual tune-up will also allow service personnel to inspect for wear and
tear of other components.
CAUTION: Operating the Hydro-Hot’s Diesel Burner or the 120 VAC
Electric Heating Element without the water and antifreeze solution will
cause serious damage to the Heater.
