SOLUTIONS
1. The inflation valve is not fully screwed into the AirPole.
2. The deflation valves are open. Close.
3. Check the pump is working.
The isolation valves that connect the AirPoles may not be open.
Open all internal isolation valves and the air will flow into all the AirPoles. Do not close the valves during
normal use.
An isolation valve may have been closed. Locate and open.
Add more air (9 psi).
1. Check that the inflation valve is properly closed and that the black 'O' ring seal is in place.
2. Check that the top cap on the inflation valve is done up tightly
3. Check that all the deflation valves are closed
Close all the isolation valves in the awning. Wait for a while and then check each AirPole for pressure. If
there is reduced pressure in any AirPole check the connecting hoses to make sure that the isolation valves
are done up tightly and are properly seated. If you still suspect a leak it will be necessary to investigate
the individual AirPole. See the AirPole repairing and changing section of this manual.
Condensation occurs when there is a difference between inside and outside temperatures and there is a
water repellant barrier between them. Condensation builds up on the inside of the tent or awning, and
with heavy condensation, it can sometimes be mistaken for leaking, especially as it can run down the
inside of the roof and drip of ties, tapes and other internal fittings.
Use the following checklist to ensure that your suspected leak isn't condensation:
Vents, Windows and Doors are open to ensure adequate ventilation
1. Choose your campsite carefully – a site that has a slight breeze will be of benefit. Avoid damp or low-
lying areas if possible.
2. Use a water repellant groundsheet throughout the awning, or under your tent will reduce the
amount of moisture & humidity coming from the ground
3. Avoid bringing wet items into the tent – as moisture evaporates, this adds to the water vapour inside
your tent or awning.
4. Check your awning or tent for holes or tears – Dometic Tent & Awning Repair Kits are available for
purchase.
If the problem is still occurring, call Dometic, or your local service agent.
The main seams of this awning have been factory taped to help prevent leakage (not All-Season).
Depending upon your expectations, it may be necessary to treat the remaining seams with a seam
sealant. Seam sealant should also be applied to areas where the taping is damaged or has peeled away
through wear and tear. It can also be applied to areas where a leak may have developed. Dometic seam
sealant is available for purchase.
It is not possible to hot air tape the join between the awning and the keder beading. Therefore we use a
special water repellant sewing thread. This thread swells when wet to fill the needle holes but the thread
needs to become wet several times before it is totally effective. This is known as 'weathering'.
