ENGINE HEAT (Optional):
The engine preheat loop is an integral part of the Aqua-Hot heating system.
In cold ambient temperatures, 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.
• Turn the Engine 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.
NOTE: Layouts may vary with difference in models and
options.
