“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.

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.

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.

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,

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.
