3. Paint the heater element body with a high temperature
resistant paint to protect the heater element against
corrosion. Allow the paint to fully dry.

4. Once the paint has dried on the heater element
body, remove the masking tape from the heater side
(non-threaded) of the heater element.

NOTICE

DO NOT remove the masking tape from the threaded
end of the heater element until the heater element is
ready for cordset installation.

COOLANT DRAINING

1. Locate and place a clean container below the coolant
drain port (Figure 5) to catch drained coolant. The
collected coolant will be reused later. Make sure no
foreign particulates or contaminates are present in
the drained coolant.

2. Using an open-ended wrench, remove the coolant drain
plug and drain approximately 1/2-3/4 gallons of coolant
(Figure 5) from the coolant reservoir.

NOTICE

2. Locate the freeze plug (Figure 7) on the engine block.

3. Reinstall the coolant access panel and run the engine
for approximately 10-15 minutes to ensure engine

thermostat functionality.

NOTICE

The thermostat will open to allow complete coolant
circulation from the radiator to the engine block.

4. Turn the engine off and let cool. Check the unit for any
leaks around the water heater. If leaks are present,
repair them immediately and check the heater element
for misalignment in the freezer plug corehole.

5. Inspect the coolant level for a final time before using
the generator on a work area.
