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 water stops coming out of the faucet, stop the
air and Close the faucet.
5. One at a time, repeat this process on all faucets 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.
