Electrical Requirements, Grounding Instructions

ELECTRICAL REQUIREMENTS

“The supply and internal wiring of portable high pressure spray washing machines shall have ground-fault-circuit- interpreter (GFCI) which is designed to protect people from line-ground shock hazards”, National Electric Code (NEC) 1987, 422, 8 (d) (3).

-All equipment and power cords connected down-line from the GFCI are protected.

-GFCI does not protect against line-to-line or line-to-neutral faults.

-GFCI does not protect against short circuits or overloads. Use a fuse or circuit breaker to guard against these occurrences.

Northern recommends that all electrical service be performed by a licensed electrician.

-All electrical connections must be made according to local, state, and federal codes to maintain a valid warranty.

-Connect the cord to a circuit that is wired for the 120 volts shown on the identification plate of the unit and properly electrically ground the connection.

GROUNDING INSTRUCTIONS

This pressure washer must be grounded. Grounding provides a path of least resistance for electric current to reduce the risk of shock if the unit should malfunction or breakdown. For your safety, plug the cord equipped with an equipment-grounding conductor and a grounding plug into an appropriate outlet. The outlet should be properly installed and grounded according to local electrical codes and ordinances.

GROUND-FAULT-CIRCUIT-INTERRUPTER

A GFCI is built into the plug of the pressure washer power supply cord. This GFCI provides additional protection from electrical shock. Use only the identical replacement parts that include GFCI protection when replacing the plug or power cord.

EXTENSION CORDS

Only use outdoor approved, 3-wire extension cords with 3-prong grounding-type plugs and 3-pole cord connectors that accept the plug from the unit. Outdoor cords are identified by: “Acceptable for outdoor appliances; store indoors while not in use”. Extension cord must have an electrical rating not less than the rating of the product. Do not use a damaged extension cord or abuse the cord by yanking. Keep cord away from heat sources and sharp objects. Always disconnect the extension cord from the power supply before disconnecting the unit from the extension cord,

!Improper connection of the equipment-grounding conductor can result in a risk of electrocution. Check with a licensed electrician if you doubt whether an outlet is properly grounded. Do not modify the product plug, install a proper outlet with a licensed electrician. Reduce the risk of electrocution, keep all connections dry and off the ground. Do not

touch with wet hands.

VENTILATION REQUIREMENTS

Permanent installation in an enclosed area or indoors should be performed by a qualified contractor. The burner exhaust must be stacked to the outside atmosphere and a barometric draft regulator is required as well.
