PLUMBING
WINTERIZING (continued)
For additional winterizing protection, add non-toxic antifreeze (approved for drinking
water systems) to your water lines using the following procedure:
1. Reconnect all lines except the hose to the pump inlet
port. Close all drain valves (See Step 3)
2. Turn bypass valves to bypass position, see illustration.
Open valve B, close valves A and C.
3. 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 shower hand 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.
Winterize Your Optional Icemaker
1. Remove the Airstream installed supply hose and the small clear Dometic supply
water line from the solenoid located in the exterior refrigerated compartment. The
solenoid is mounted to back of the refrigerator.
2. Drain the small clear hose and blow out and drain the solenoid and large water
supply line.
3. A shut off valve is located under the refrigerator and can be accessed by removing
the louvered panels on the lower refrigerator front cabinet. The valve is to the front of
the area and just below the refrigerator stand. This valve must be turned off if the fresh
water system is being used in freezing weather. The water feed line to the icemaker
runs through the exterior compartment and can freeze if this valve is not shut
