1.
The water heater must remain off during this process. Shut off the water
pump and make sure the water supply valves are closed. Disconnect the
city water fill.
2.
To drain the fresh water tank, open the drain valves.
3.
Open the low point drain valves. There is one drain valve for each water
line, one cold and one hot. This is done to drain all of the water out of the
system.
4.
After the water heater has cooled off, remove the drain plug to drain the
water from the water heater. In the exterior compartment beside the water
heater there are two water heater shut off valves and a by-pass valve. The
shut off valves must be closed and the by-pass valve must be open, prior
to winterizing to prevent the antifreeze solution from entering the water
heater.
5.
Close the low point drains to prevent the antifreeze from draining through
the lines onto the ground.
6.
Close the water supply valve that flows from the pump to the tank.
7.
Use only non-toxic antifreeze that has been approved for use in
drinking/potable water systems. Place the in-take hose into the antifreeze
supply. Open the antifreeze valve to allow the solution to flow freely.
Once the water pump is turned on, proceed to the kitchen faucet, bath
faucet, inside and outside shower, turning on the hot and cold, and
flushing the stool until the antifreeze solution flows freely. If the unit is
equipped with a washer, be certain to purge the air from it also. This
forces the antifreeze through all of the water lines and faucets. It also
allows the antifreeze solution to enter the drain lines and prevent the P-
traps from freezing. Check the antifreeze solution from time to time to
make sure there is an adequate supply.
8.
Close the antifreeze valve when the winterizing process is complete. Store
the in-take hose, and turn the water pump off.
9.
Open the water supply valve that flows from the pump to the tank to help
prevent freezing on that water line.
10.
To de-winterize your unit, open both of the low point drains to allow the
antifreeze solution to drain from the water system. Next, close the low
point drains and connect your unit to city water. Put water in the fresh
water tank and pump at least one gallon through the water pump in order
to remove the antifreeze from the water pump. Keep the water heater
supply valve closed and the water heater bypass valves open. The supply
valve for the fresh water tank from the pump must remain closed. As in
winterizing, open the kitchen faucet, bath faucet, inside and outside
