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 tanks and the water lines, replace the
drain plug.
