NORTHWOOD 2004 series Owner's Manual - Ground Fault Interrupter:

GROUND FAULT INTERRUPTER:
Kitchen and patio 120-volt electrical outlets are
protected by a Ground Fault Interrupter (GFI). This device is provided in compliance with ANSI
A119.2/NFPA 501C requirements and is intended to protect you against the hazards of line to ground
electric faults and electrical leakage shocks possible when using electrical appliances in the kitchen,
or damp areas inside or outside of the unit. Whenever you plug your 120-volt system into shore
power, it is recommended that you verify that the adapter and power source are wired in proper
sequence. Occasionally we have found that some home or garage wiring installations have been
done improperly. Even though your camper may appear to operate properly, there is danger of
electrical shock–especially in wet areas–if power source wiring has been incorrectly installed in the
home, garage or other facility. If the shore power has been improperly wired, the built in safety
devices in your camper may not function correctly. A simple continuity checker (wiggie) will verify
wiring integrity. If you suspect that an external extension cord or adaptor may not have been supplied
by a properly licensed electrician, be sure to check the power source before use to avoid the danger
of an electrical shock.
FRESH WATER SYSTEM
Fresh water is supplied to the camper by two alternate sources.
1.
The external hookup (city or park water).
2.
Self-contained water (on board storage tank).
EXTERNAL HOO KUP (City or Park Connection):
To use the external water
system connect the water hose from the city or campground source to the hose connector on the side
of your unit. Be sure to run the water for a few seconds to clear the hose before connecting to the
unit. A check valve at the water pump prevents city water from being fed back through the pump and
into the water tank. Another check valve prevents water from being pumped out through the city
water connection when the self-contained water system is being used in the unit. The water heater is
equipped with a safety-relief valve which will open if a surge of pressure should occur. The water
system has been tested for leaks at the factory at 90-100 PSI.
IMPORTANT: EXCESSIVE WATER PRESSURE. Some city or campground water systems may
operate at pressures that can damage the water system in your camper or cause water pump failure.
If pressure at your site is over 70 PSI, you must use a pressure regulator. The recommended
pressure range is from 35 PSI to 45 PSI. Your RV supply dealer can advise you on the best choice
regarding water pressure regulators.
IMPORTANT: The 12-volt DC water pump switch should be in the ”OFF” position when the camper is
connected to a city or campground source.
SELF-CONTAINED WATER SYSTEM:
The fill spout for the onboard fresh water
storage tank is located on the outside of the camper. The electric 12-volt DC pump supplies the
pressure for the self-contained water system. You can check the approximate water level by pressing
the “water” rocker switch on the monitor panel. Erroneous readings could be caused by water with
low mineral content.
