Engine Preheat:
The Aqua-Hot system has an engine preheat feature to aid engine starting in cold weather. Inside
the Aqua-Hot are an engine coolant loop and pump. The Aqua-Hot will heat the engine coolant. The
internal engine pump will circulate heated coolant through the engine.
To Use the System:
• Turn the Aqua-Hot Diesel switch, at the kitchen switch panel, to the ON
position.
• Turn the Aqua-Hot Engine preheat switch, at the center dash console, to the
ON position to activate the engine pump inside the Aqua-Hot. The time
required to preheat the engine varies with ambient temperature. Allow at
least three hours of engine pre-heat time.
Engine Heat Exchange System:
When traveling, the water pump on the engine circulates heated engine
coolant through the Aqua-Hot. Through convection, heat transfers to the Aqua-
Hot coolant, providing hot water and interior heating. Use the Comfort Control
to operate the heat exchangers.
To Use the System:
• Turn on the interior house power.
• Set the Comfort Controls to Furnace.
• Select the desired Zone and Temperature.
