Winterizing The Waste System - Four winns 248 Vista Owner's Manual

NOTICE
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.
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 be-
comes empty.
2. Add 15 gallons of R.V. antifreeze to the water tank.
NOTICE
Generally 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 antifreeze
coming out.
4. Activate the shower sump pump and pour approxi-
mately 1 quart of nontoxic antifreeze down the shower
drain. The shower sump will discharge some of the
antifreeze overboard.
Use only nontoxic antifreeze solutions such as
R.V. antifreeze. DO NOT use ethylene glycol
solutions; the type that is used in engine cool-
ant systems. These are toxic.
NOTICE
Be sure to wipe up any antifreeze that has been
spilled on the fiberglass shower surfaces.
C. Winterizing the Waste System
To winterize the waste holding tank, flush the tank with
soap, water and a deodorizer (e.g., Lysol Liquid™). Empty
the tank and pour two (2) gallons (3 gallons if equipped
with overboard discharge) of R.V. antifreeze into the bowl
and flush.

™
If the boat is equipped with overboard discharge capabili-
ties, follow the normal procedures above. Run the dis-
charge pump only long enough until the antifreeze solu-
tion is being pumped overboard.
For additional information, refer to the manufacturer's
manuals in the owner's packet.
NOTICE
The instructions listed in this section provide a
working knowledge to winterize the water and
waste systems. However, to prevent possible
damage to components in your boat, Four Winns
recommends having the boat winterized by your
Four Winns dealer.
