PRECAUTIONS
WARNING: Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury.
WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.
WARNING: Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
We recommend that you do the following
for a safe and correct operation:
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter's Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold

temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
Use as short an extension cord as
possible.
Do not use multiple extension cords.
(IF
Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
If the block heater cord is under the
hood, do not remove the wiring from
its original location. Do not close the
hood on the extension wiring.
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 about 30 minutes.
Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
Make sure the heater system is
checked for proper operation before
winter.
HOW DOES THE ENGINE BLOCK
HEATER WORK
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded
220-240 volt AC electrical source.
