AQUAHOT ENGINE PREHEAT:
The engine preheat loop is an integral part of the Aqua-Hot heating system. In cold ambient tem-
peratures, use this feature to preheat the engine. The Aqua-Hot also supplies supplemental heating
to the interior using heat created by the engine. While traveling, the water pump on the engine
coolant will pass through the Aqua-Hot. When using the supplemental heating feature, use the
Comfort Control thermostat to activate the desired heat exchangers.
To Enable Engine Preheat:
• Turn the Aqua-Hot switch on at kitchen.
• Turn the Aqua Hot Engine Pre-Heat switch ON to activate the engine preheat circulation
pump. Circulating engine coolant through the engine pre-heat loop will adequately warm
the engine to operate for easy starting.
• Allow approximately one to two hours (longer for colder, ambient temperatures) of engine
preheating run time. The pump can be operated overnight if desired.
• Turn the engine heat switch OFF when engine preheating is not desired.
