B. Turn OFF the Aqua-Hot's Engine Preheat 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 120
VAC Electric Heating Element. While traveling, the engine's heated
coolant will automatically pass through the Engine Preheat / Motoraide
System, transferring heat into the Aqua-Hot's Heat Tank. This design
feature reduces the total operating hours of the Diesel-Burner and the
120 VAC Electric Heating Element.
