5.1 General Maintenance
Monthly
Check the Aqua-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 Aqua-Hot's Expansion Tank, see Figure 1. This should be checked
only when the Aqua-Hot is at full operating temperature, "HOT."
Annually
CAUTION: Before cleaning or servicing, disconnect all power
supplies.
It is ideal to have your Aqua-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, see Figure 8. This
simple tune-up will keep your Aqua-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 Aqua-Hot's Diesel-Burner or the 120 VAC
Electric Heating Element without the water and antifreeze solution will
cause serious damage to the Heater.
