Ducts
Remove the protective caps of the valves [E] and the protection caps of the duct [F].
First tighten the thin duct on the upper valve [G].
Then tighten the thick duct on the lowest valve [H].
Check for leakage.
Open the upper valve with the socket wrench [I].
Check on both connections for leakage, by applying a sponge with soap-suds to the
valves.
Close the valve immediately with the socket wrench in case of a leakage.
Call for assistance of your installer if, after you have checked that the ducts are well
fitted, there is nevertheless a leakage. Keep the valves closed!
If there is no leakage, open the bottom valve with the socket wrench [J].
