CAUTION:
Upon cranking an engine in cold temperature, the starter may rapidly engage and
disengage. If this occurs STOP attempting to crank the engine as starter damage
may occur. Pre-heat the engine before making further attempts to start the
engine.
Block Heat:
The switch labeled Block Heat operates the receptacle for the block heater cord. The block heater,
depending on engine size, is rated between 850 and 1500 watts. For efficiency hook to shore power. An
auxiliary method is to plug the block heater cord to a separate power cord, as long as the power cord is
rated for 15 Amps and the outlet used is GFCI protected rated at 20 Amps. The engine may require
several hours of pre-heating before before starting. It is recommended to start pre-heating the engine
the night before departure.
To Use the Block Heater:
• Hook to shore power and plug in block heater cord to the receptacle.
• Turn on the Block Heat switch.
Aqua-Hot Engine Pre-Heat:
The diesel burner inside the Aqua-Hot heats an internal engine coolant loop. When the Aqua-Hot
Engine Pre-Heat switch is turned on, an engine coolant pump inside the Aqua-hot circulates heated
coolant through the engine. The time it takes for the Aqua-Hot to pre-heat the engine depends on ambi-
ent temperature. Allow at least three hours of pre-heating before attempting to start the engine.
To Use the System:
• Turn the Aqua-Hot switch at the kitchen to the ON position.
• Turn the Aqua-Hot Engine Pre-Heat switch at the dash to the ON position. This activates
the engine pump inside the Aqua-Hot.
Tips:
1. When operating below 32º F, the engine block heater can enhance engine starting by eas-
ing cranking and helping to prevent engine misfire and white smoke during starting.
2. Always follow the recommended oil, fuel, and coolant specifications as outlined in the
OEM Engine Manual. Proper oil viscosity and coolant concentration eases engine starting
and helps to avoid engine damage.
3. Allow the engine to idle until it sufficiently warms for operation. Utilize the fast idle fea-
ture to quicken the process. Wait to operate the motorhome for at least three minutes or
until the coolant temperature begins to move.
