10� After the water has stopped running from the drain

lines, apply at least 60 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.

11� 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.

12� 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.

13� If so equipped, remove the cartridge of the water

purifier and leave the purifier valve in the open

position.

14� Remove the batteries from your trailer and store

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

charged�

15� Remove any items (food, cosmetics, etc.) from

trailer interior that might be damaged by freezing,

or that might damage the trailer if containers

should break.

CAUTION

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

finish.

For additional winterizing protection, 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. Close all drain valves.

2� Turn water heater bypass valve on while turning

the other two valves to the off position. See photo

below for valves being referred to.

3� Replace the galley faucet filter with the bypass pipe

(refer to Galley Faucet Filter in Section 5 - Interior).

Store filter in a warm place.

4� 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.

5� For antifreeze usages follow manufacturer's

instructions found on label of container.

6� Open all water faucets.

7� 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.

8� Shut off the pump and close all faucets.

9� Disconnect the hose length from pump inlet fitting

and reconnect water system inlet line.
