switch whenever engine
preheating is not desired.
NOTE:
The Aqua-Hot's Engine Preheating System acts as a
supple-
mental heating source
in addition to the Diesel-Burner and the Electric
Heating Element(s). While traveling, the engine's heated coolant will
automatically pass through the Engine Preheat / Motoraide System,
transferring heat into the Aqua-Hot's Boiler Tank. This design feature
reduces the total operating hours of the Diesel-Burner and the Electric
Heating Element(s).
