We recommend that you do the following fora safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified by Underwriter’sLaboratory (UL) or Canadian StandardsAssociation (CSA). This extension cordmust be suitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and engine blockheater cord plug connections are freeand clear of water. This could cause anelectric shock or fire.
•If the engine block heater cord is underthe hood, do not remove the wiring fromits original location. Do not close thehood on the extension wiring.
•Park your vehicle in a clean area, clearof combustible materials.
•Firmly connect the engine block heatercord and the extension cord.
•Check the extension cord for heatanywhere when the system has beenoperating for approximately 30 minutes.
•Unplug and properly stow the systembefore starting and driving your vehicle.The protective cover seals the terminalsof the engine block heater cord plugwhen not in use.
•Check the engine block heater systemfor proper operation before winter.
HOW DOES THE ENGINE BLOCKHEATER WORK
