Section III. OPERATION UNDER USUAL CONDITIONS
ASSEMBLY AND PREPARATION FOR USE.
The kit is installed on the generator. No assembly or preparation for use is required. For operation of the
generator, refer to TM 9-6115-642-10.
Winterization Kit. Usual conditions for operating the heater imply extremely cold temperatures. The heater allows
the generator set to operate between -25F and -50F (-45.6C). Both the MEP-803A and MEP-813A will start
without the winterization kit down to the ambient temperatures of -25F. Although not required, use of the
winterization kit will aid starting and reducing engine wear in ambient air temperatures between -25F to 32F.
Heater operation is automatic after the ON/OFF switch is placed in the ON position.
Depending on temperature, heater could take up to 1 hour to activate heater control circuits.
At least 30 minutes before generator is to be started, put the heater switch on generator control panel in the
ON position to activate heater control circuits.
When the coolant temperature reaches 176F (80C), the heater switches to low heat mode.
Check temperature gauge if you have a reading of 176F.
When generator is started, place heater ON-OFF switch in OFF position. The indicator light
should go off.
PREPARATION FOR MOVEMENT.
The kit is installed on the generator. No preparation for movement is required beyond that for moving the
