POST-INSTALLATION TESTING
1. Remove the coolant port access panel on top of the
generator (Figure 13) and refill the coolant reservoir
with the 1/2-3/4 gallons of coolant previosuly drained.

) to the negative
terminal on the battery.
3. Reinstall the coolant access panel and run the engine
for approximately 10-15 minutes to ensure engine
thermostat functionality.
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.
