Information supplied with water system compo-
nents by the equipment manufacturers is included
with this manual. Refer to this information for
additional operation and service data.
The following items should be done routinely to
maintain your fresh water system:
Periodically remove and clean the water
strainer located at the intake side of the
pressure pump. To clean the strainer, make
sure the Fresh Water Pump switch is o.
Rotate the strainer bowl counterclockwise to
release it. Remove and clean the screen with
fresh water. Lubricate the O-ring lightly with
Teon or silicon grease and reinstall the screen
and strainer bowl.
Periodically spray the pump and metal
components with a metal protector.
The batteries must be properly maintained and
charged. Operating the pressure pump from a
battery with a low charge could lead to pump
failure.
Add a commercially available potable water
conditioner to the water tank to keep it fresh.
Sanitizing the Fresh Water Tank
The freshwater system should be sanitized if it has
not been used for a long period or you are unsure
of the quality of the water in the system.
The following steps can be used to sanitize the
system:
Activate the system and pump out as much
water as you can.
Make a chlorine solution by mixing two ounces
of household chlorine bleach in a gallon of
water. This mixture will treat approximately
fteen gallons. If the water tank on your
boat is larger or smaller than 15 gallons, then
adjust the mixture accordingly. Always mix
the chlorine with water in a separate container
rst and never add straight chlorine to the
fresh water tank.
Fill the water tank half full with freshwater and
pour the mixture into the water tank. Top o
the tank.
Activate the system and allow the water to run
from the washdown hose for about 1 minute.
Let the treated water stand for 4-6 hours.
Drain the system by pumping it dry and ush
with several tank lls of freshwater.
The system should now be sanitized and can
be lled with freshwater. If the chlorine smell
is still strong, it should be ushed several more
times with freshwater.
C AU T I O N
THE FRESH WATER SYSTEM MUST BE PROPERLY
WINTERIZED PRIOR TO WINTER LAY-UP. SEE SECTION ON
WINTERIZING.
