AIRSTREAM LAND YACHT GAS
STORAGE AND WINTERIZING
When storing your motorhome for a short or long period, use the same precautions as you would in your
own home in regard to perishables, ventilation and rain protection. In addition, for prolonged storage
periods flush out all the drain lines and the holding tanks. Also, drain the entire water system, including the
water heater and the water storage tank. Instructions for draining the water system are explained in the
following paragraphs on winterizing.
Twice a year, or after a long storage period, we suggest you take your unit into your Airstream dealer for a
check-up and cleaning of the gas operated appliances

The main consideration in winterizing is to guard against freezing damage to the hot and cold water
systems, the waste drain system (including the traps), the waste holding tanks, the water heater and the
batteries. To completely winterize your motorhome follow this procedure:
1. Level the motorhome from side to side and front to rear. Open all faucets.
2. Turn the water pump switch to the OFF position.
3. Open all drain valves. See Drain and High Pressure Water Valves in this section.
4. Follow winterizing instructions for your toilet in the toilet section of this manual.
5. While the water is draining from the system, depress hand spray thumb button on the telephone
showerhead and drain all the water. Unscrew the head on spray unit and store.
6. After the water has stopped running from the drain lines, apply at least 60 lbs. of air pressure at the city
water inlet. Be sure the toilet valve and all drain valves and faucets are open and pump outlet hose
is disconnected. This can be accomplished at a service station and will force any remaining water
from the water heater and remove any water which may be trapped in low areas.
7. Pour a cup of non-toxic antifreeze into the lavatory, sink, and tub drains to prevent freezing water in
traps.
8. Be sure to open the waste holding tank drain valves, and drain and flush the tanks thoroughly. (This is
very important, as the frozen sewage could seriously damage the tank.)
9. Remove water filter canister and dump.
10. Remove the batteries from your motorhome and store in a cool dry place where there is no danger of
freezing. It is very important for optimum life of your battery to check it periodically and to keep
it fully charged. This is especially true in winter months, when the temperature may drop below
freezing. If the period of storage is for 30 days or less, you may turn off the "kill" switch rather
than remove the batteries,
Please refer to the battery section for more information on battery maintenance
11.Remove any items (food, cosmetics, etc.) from the interior that might be damaged by freezing, or might
damage the motorhome if containers break.
12. If you have an optional icemaker, read and follow the winterizing directions in the manufacturer’s
owner manual. Open shut-off valve to drain the icemaker at the same time you drain your
motorhome. If the motorhome is to be used in freezing weather, do not open valve and use the
icemaker.
