CAUTION: Excessive pressure from water supply may be encountered in some
parks, especially in mountain regions. Water pressure regulators are available to
protect your system against such high pressure. A regulator of this type is recom-
mended to prevent damage to plumbing systems or components. A 45 pound rating
is suggested.

12-Volt Demand Pump

When water is desired and you are not hooked up to city water, you need to turn on 12-
volt power to start demand pump. You will find the switch on the monitor panel or a wall
near the pump. The battery or convertor will supply energy for pump which will self-
prime and provide water. The pump continues to run until approximately forty pounds of
pressure is achieved and automatically starts again when pressure drops to twenty
pounds. Some cycling in pump may occur, depending on volume of water being released.
A check valve is built inside of pump to prevent water from flowing into supply tank.
When the water pump is not used, turn the 12-volt power off.
CAUTION: Not using a water pressure regulator when using city water fill may
cause the o-rings to blow. It is advisable to always utilize a water pressure regulator
with the city water fill.

Faucets

Bathroom or kitchen faucets operate the same as in your
home. Open by turning knobs. There may be air in lines
which needs to be bled out. Close faucets when sufficient
water is released.
