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.
