SOLUTIONS
1. The infl ation valve is not fully screwed into the AirPole.
2. The defl ation 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 fl ow into all the AirPoles. Do not close the
valves during normal use.
Add more air (9 psi).
1. Check that the infl ation valve is properly closed and that the black 'O' ring seal is in place.
2. Check that the top cap on the infl ation valve is done up tightly
3. Check that all the defl ation 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.
Most suspected leakage is actually condensation (see condensation section of this
manual). This forms on the inside of the awning fabric. Try to increase the ventilation by
opening doors. A waterproof groundsheet will help stop moisture from the ground causing
condensation. The fabric, used to make this awning, has a massive hydrostatic head, so it is
extremely unlikely that it would leak.
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
from your dealer.
It is not possible to hot air tape the join between the awning and the keder beading.
Therefore we use a special waterproof sewing thread. This thread swells when wet to fi ll the
needle holes but the thread needs to become wet several times before it is totally eff ective.
This is known as 'weathering' .
