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, because more than likely
it will be difficult to start the generator. 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 must be GFCI protected rated at 20 Amps.
The engine may require several hours of pre-heating before it will start. It is
recommended to start pre-heating the engine the night before departure.
Remember to turn off the block heater switch or unplug the separate power cord.
To Use the Block Heater:
• Hook to shore power and plug in block heater cord to the receptacle.
• Turn on the Block Heat switch.
Engine Heat:
The diesel burner inside the Aqua-Hot heats an internal engine coolant
loop. When the Engine 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 ambient temperature.
Allow at least three hours of pre-heating before attempting to start the engine.
To Use the System:
• Turn the Aqua-Hot switch to the ON position.
• Turn the Engine Heat switch to the ON position. This activates the
engine pump inside the Aqua-Hot.
The maintenance guidelines in the Cummins Operation & Maintenance
Manual are the recommendations for the engine. Following it helps extend the
engine life and improve performance, resulting in cost efficient operations. A
good maintenance schedule begins with a daily awareness of the engine and its
various systems.
A high grade 15W-40 multiviscosity heavy duty lubricating oil meeting
Cummins Engineering Specification CES 20071 or CES 20076, American
Petroleum Institute (API) specification CH-4 which can be used as an
alternative to CES 20071 is recommended. Lubricating oils meeting API
CG-4 specifications may be used at a reduced drain interval. The engine uses
Pennzoil 15W-40 heavy duty engine lubricating oil that meets Cummins
specifications. A critical factor in maintaining engine performance and
durability is the use of high grade multigrade lubricating oil and strict
adherence to the maintenance service intervals.
