4� 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�
5� Dilute the antifreeze solution in accordance with
the manufacturer's instructions.
6� Turn the pump switch on, and run the water pump
until the antifreeze solution fills all water lines.

and reconnect water system inlet line. If you have
the winterization kit, turn valve back into normal
use position and reinstall hose plug.
Maintaining The Heating System
Regularly check the heating system fluid level in the
expansion tank located, depending on the model,
behind a removable panel in the bathroom cabinet
above the toilet or behind a removable panel between
the shower and sofa wall. The tank has markings
on the side to indicate the maximum and minimum
level for the fluid. The fluid level should be about .5
inches above the minimum indicator in a cold tank.
Please refer to the Alde Owner's Manual provide
in your owners packet for further maintenance and
winterization tips.
Main Door Care
Lubrication
Apply a little paraffin or grease to the striker pockets
and a slight amount of household oil to the lock
mechanisms to keep the locks operating smoothly.
Also, lubricate the hinge pins periodically with
household oil. Use the lubricant sparingly and
immediately remove any excess from exterior skin.

Adjustment
Main door adjustment can be affected by:
• The trailer being improperly leveled (causing twisting
of trailer body/shell).*
• Striker bolt alignment being out of adjustment,
(striker bolt is adjustable).
• Screen door being out of adjustment, resulting in a
situation of the door rubbing the frame, or not closing
flush (which will create pressure on the door).
• Main door has come open at some point, introducing
a change to the contour of the door frame (check for
sheared rivets on interior skin of door).
* When using the stabilizers (for eliminating movement-
not leveling) on your Airstream, be sure to check
the fit of your main door before and after extending
stabilizers. The fit of the main door can be affected if
trailer is not level side to side and front to back.
