open. Freezing water can cause severe damage to all
water system components.
The decomposition of waste produces a color-
less, odorless gas, methane, that is lighter than
air, combustible, and extremely lethal. Always
provide sufficient ventilation when effecting re-
pairs to the waste system and allow no odor
from the waste system to go unresolved.
NOTICE
Always winterize the fresh water system prior
to winterization of the hull drainage (bilge pump)
system.
Draining the system as mentioned can be very tedious
and an incomplete job can result in expensive repairs.
The use of nontoxic antifreeze (such as R.V. antifreeze)
A. Clean Vents and Screens
Periodically, inspect the water tank vents and thru-hull designed for fresh water systems considerably reduces
vent fittings for any dirt, wax, etc. Carefully remove any the work necessary and is a more positive means of
obstruction with a pipe cleaner or similar device. Be winterizing the system. Follow the directions included
sure not to puncture the screen. The stainless steel with the antifreeze solution.
vent cap is not removable.
To winterize:
NOTICE
Failure to keep the water tank vent fittings clean
will cause excessive pressure buildup within the
tank during filling. This can cause water tank
damage.
1.
Turn on the water pump and drain the water tank by
opening a faucet (the pump will run faster when it is
empty).
NOTICE
Periodically remove the filter screens from the faucet dis-
chargespoutsandshowerhead. Removetheaccumula-
tion of sediment from the screens. If necessary, clean
out the holes using a fine wire. A buildup of debris in the
faucet filter screens can create enough restriction to
cause the pump to cycle on and off.
Be sure the circuit breaker for the water heater
in 120 Volt AC panel is in the OFF position. The
water heater will be damaged immediately by
supplying electrical power to an empty water
heater.
NOTICE
Check the in-line water filter/screen for sediment and
blockage. It is located between the water tank and the
pressure water pump. If obstructed, remove from the
water line and either clean or replace the part. The filter
unit will twist apart.
DO NOT run the water pump without water in
the system. Pump damage will result. Be
watchful and turn the pump off as soon as the
tank becomes empty.
2.
Add 15 gallons of R.V. antifreeze to the water tank.
Inspectandcleantheshowersumpevery30days. Some
water will always be in the compartment. Sediment and
other debris will buildup and affect the automatic bilge
switch and pump operation. Remove the pump’s cover
and clean the screen. The screen will become blocked
and the pump will not operate properly. To clean the
compartment, use baking soda and a fine wire brush to
remove dirt and other debris. This will also serve to dis-
infect the area.
NOTICE
The hot water heater will require approximately
five gallons of antifreeze before the hot water
lines will have antifreeze running through them.
The cold water faucet should be turned OFF at
some point to test for antifreeze in the hot water
line.
3.
Turn ON all faucets (both hot and cold) until undi-
luted antifreeze is seen. Make sure the transom
shower, head faucet and galley faucet have anti-
freeze coming out.
B. Winterizing the Water System
Winter lay-up service procedures should include a thor-
ough draining of the water system. Disconnect all ac-
cessible fittings. Blow out all lines. Be sure the hot wa-
ter heater, fresh and gray water tanks, transom shower,
pumps and lines are completely dry. Leave all faucets
