inside the bowl. Depress hand spray thumb button
on the telephone shower head while holding down
inside the tub and drain all water from the flexible
hose. Unscrew the heads on both spray units and
store.
5� Turn the pump switch OFF after all water has been
removed from the storage tank.
6� Disconnect outlet hose from water pump.
7� If your unit has a winterization kit installed, open
valve to the winterizing position and remove plug.
If your unit does not have this valve, disconnect
the water pump inlet connection. Turn the pump
on until all the water is expelled. This water,
about 1/2 cup, can be caught in a towel or rag.
8� Lower the front of the trailer as far as the jack
will allow until water ceases to drain, then crank
the jack up as high as it will go and allow any
remaining water to drain out.
9� After the water has stopped running from the drain
lines, apply 50 lb. of air pressure at the city water
inlet. An air-to-city water adapter is available from
your dealer's RV accessory store. Be sure the
toilet valve, all drain valves, and faucets are open
and pump outlet hose is disconnected. This can
be done at a service station and will force any
remaining water from the water heater and remove
any water that may be trapped in low areas.
10� Pour a cup of non-toxic RV antifreeze that has
been approved and listed by a recognized testing
authority such as Underwriter Lab into the lavatory,
sink and tub drains to prevent trap freeze-up.
11� Be sure to open the waste-holding tank dump
valves and drain and flush the tanks thoroughly
(this is very important as the sewage in the tanks,
if frozen, could seriously damage the tanks)� Plan
ahead and have this done at a dump station.

in a cool, dry place where there is no danger of
freezing. It is very important for optimum life of a
battery to check it periodically and to keep it fully

trailer interior that might be damaged by freezing,
or that might damage the trailer if containers
should break.
Remove all RV antifreeze spillage from all drain
and faucet parts after winterizing. Failure to do so
could result in damage to the plumbing fixture's
An Optional, method for winterizing protection, is to
add a non-toxic antifreeze (approved for drinking
water system) to the water lines using the following
procedure:
1� Reconnect all lines except the hose to the pump
inlet port. If you have the winterization kit installed,
just reconnect the outlet hose. Close all drain
valves.
.
2� Turn water heater bypass valve to bypass position.
Refer to Water Heater Bypass Valve illustration.
3� If you do not have the winterization kit, attach a
length of hose to the pump inlet port. This piece of
hose should be long enough for the free end to be
inserted into and reach the bottom of the antifreeze
container�
4� Dilute the antifreeze solution in accordance with
the manufacturer's instructions.
5� Open all water faucets.
6� Insert hose length into the antifreeze container,
turn the pump switch on, and run the water pump
until the antifreeze solution fills all water lines.
Flush toilet. Work hand shower spray while holding
down in tub.
7� Shut off the pump and close all faucets.
8� Disconnect the hose length from pump inlet fitting
and reconnect water system inlet line. If you have
the winterization kit, turn valve back into normal
use position and reinstall hose plug.
