STORAGE
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 a prolonged storage
period, 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.
The Sky Deck area should be protected from long-term exposure to snow and ice. The freezing and
thawing of snow and ice can damage the streamliners and other areas of the Sky Deck. Remove cushions
and store them. Cover the sky deck area or put the motorhome in an inside storage facility. Follow all
winterizing and storage procedures outlined in this manual.
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
WINTERIZING
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 the two drain line valves in your utility compartment as well as the exterior water
faucet. Open the water tank drain valve also located in the utility
or open petcock on the exterior face of the water heater. Sky Deck owners must be sure the
shut off valve to the wet bar is open for the roof plumbing to properly drain. It is located
inside the washer/dryer cabinet. Lift the cover behind the appliance to access the valve.
4. The toilet water valve should be left in open position while draining water. It is located in the
lavatory cabinet.
5. While the water is draining from the system, depress the button on all hand spray heads and
drain all 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 sewage in the tank, if frozen, could seriously damage the tank.)
9. 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,
10. Remove any items (food, cosmetics, etc.) from the interior that might be damaged by
freezing, or might damage the motorhome if containers break.
