Freshwater System Winterization
1. Turn On the freshwater pump switch.
2. Open all of the faucets and showers and let the freshwater system drain completely.
3. Turn Off the freshwater pump switch.
All remaining water must be removed from the water lines. There are two ways to remove the remaining water from
the lines:
•
Compressed Air
•
Gravity Draining
Compressed Air
You must have an air compressor with an air hose and
an air nozzle.
1. Remove the water line from the outlet side of the
freshwater pump (opposite side from filter).
2. Open the faucet that is furthest away from the fresh-
water pump.
3. Place the air nozzle against the end of the just
removed water line and blow air through the system.
4. When the water stops coming out of the faucet, stop
the air and Close the faucet.
5. One at a time, repeat this process on all of the fau-
cets and showers.
Gravity Draining
1. Open all faucets and showers.
2. Remove the drain plug from the tee fitting on the
freshwater tank.
3. When the water has stopped draining from the
freshwater tank and the water lines, replace the
drain plug.
