Avoid leaving water in the tank when the motor
home is not in use. Turn the water pump OFF before
draining the water tank. Whenever possible, drain the
fresh water tank before traveling. Water in the tank
will reduce the carrying capacity of the motor home.
See "WEIGHING AND LOADING" section.
Water Purifier System
The water purifier system in some Bounder models
can help provide consistent drinking water quality as
you travel. A special filter is part of this system. The
filter cartridge is located in the water utility compart-
ment, and is easily replaced. Your Owner's Informa-
tion Package contains detailed operating and
maintenance instructions concerning this system.
Galley Faucets
Please note that the special faucet at the galley is
the only outlet for the purified water. Although purified
water is not available at the standard galley and lavy
outlets, the water available at these outlets is filtered
by the water pump filter.
The Water Pump
The onboard fresh water system is pressurized by
a self-priming, 12-volt DC pump. The pump operates
automatically when the pump power switch is ON and
a faucet or valve is opened. When the faucet or valve
is closed, the pump shuts off. A built-in check valve
prevents back flow and protects the pump and fresh
water tank from excessive city water system
pressures up to 200 psi. The pump stroke will over-
come air trapped in the lines thus preventing air lock.
Atfree flow, the pump draws approximately 7 to 7-
y,
amps, and can run dry for extended periods without
damage. A 1 O-amp fuse at the converter panel pro-
tects the pump circuit. See ELECTRICAL SYSTEM.
Turn the pump ON to pressurize the system. When
a faucet is opened after the initial filling of the tank,
the water may sputter for a few seconds. This is nor-
mal and is not cause for concern. The water flow will
31
become steady when all air is bled from the water
lines.
The Monitor Panel
The monitor panel allows you to conveniently check
the approximate levels in the fresh water tank and the
holding tanks. Electrical probes installed in the tgnks
measure the levels at various points in the tanks. To
check tank levels:
• Press "WATER" or "HOLDING TANK 1" or "2"
rocker switches. HOLDING TANK 1 is the black
water (toilet waste) tank, and HOLDING TANK
2 is gray water (sink and shower wastes).
• The "E" or empty indicator light will always be
lit. If the tank is full, all lights will be on. Lights
are sequential, and indicate level in approximately
y.
tank increments. If the tank selected is approx-
imately Y, -full, for example, lights "E",
"y.",
and
"%" will be on.
• Erroneous indications can be caused by:
a. Water with low mineral content. Level is
measured by a very low level electrical signal
traveling through the liquid. Some water, very
low in mineral content used in the fresh water
tank, may not conduct the Signal properly. This
condition may be infrequent, but can exist.
Check the panel reading when the fresh water
tank is filled.
b. Material trapped on the sides 9f the holding
tanks may give a full reading when the tank
is actually empty.
Sanitizing The Fresh Water System
Sanitize the fresh water tank and piping at least
once a year, and whenever the motor home sits for
a prolonged period. This will help keep the tank and
lines fresh, and will discourage the growth of bacteria
and other organisms that can contaminate the water
supply. Use a chlorine/fresh water rinse as follows:
1. Prepare a solution of
Y.
-cup household liquid
chlorine bleach (5% sodium hypochlorite) to one
