WARNINGS
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.
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.
Note: The heater is most effective when
outdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warming
the engine coolant. This allows the climate
control system to respond quickly. The
equipment includes a heater element
(installed in the engine block) and a wire
harness. You can connect the system to a
grounded 120-volt AC electrical source.
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.
•
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.
•
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 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.
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.
