Starting and Stopping the Engine
• Make sure that when in operation, the extension cord plug and the
heater cord plug connections are free and clear of water. This could
cause an electric shock or fire.
• Make sure your vehicle is parked in a clean area, clear of
combustibles.
• Make sure the heater, heater cord and extension cord are firmly
connected.
• Check for heat anywhere in the electrical hookup once the system has
been operating for approximately 30 minutes.
• Make sure the system is unplugged and properly stowed before driving
your vehicle. Make sure the protective cover seals the prongs of the
block heater cord plug when not in use.
• Keep plug terminals clean and free of dirt and corrosion.
• Make sure the heater system is checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are clean and dry prior to use. Clean
them with a dry cloth, if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. The
system does not have a thermostat. It achieves maximum temperature
after approximately three hours of operation. Using the heater longer
than three hours does not improve system performance and
unnecessarily uses electricity.
