ALSIFLEX 1430 sealing ring (thickness 10) should be placed on it. This procedure
applies to the FLEX devices C1, C2 and C3. There are two cylindrical flame filters in
the FLEX devices C4 and C5. The procedure differs from the previous one only with
the fact that an adaptor should be inserted between these cylindrical flame filters, and
between the adaptor and the new cylindrical flame filters the sealing ring ALSIFLEX
1430 (thickness 10) should be installed. The entire FLEX should then be covered
with the lid; it should be slipped over the welded threaded rods and fastened tightly
against the low nuts, which were adjusted into the correct position by the
manufacturer. Do not tamper with the low nuts. The tightening of the upper nuts
should be performed using the “cross” method; after tightening, check each nut again.
9) A new membrane (a spare part from the supplier) can be sealed from the underside
to this prepared FLEX, using the silicone sealant suitable for this application. The
identical flange gasket supplied by the company RSBP spol. s r.o. can also be used;
the gasket is commonly used between the membrane and the flange on the
technology. Please note that the membrane must face with the signalling device
towards the FLEX entry and the signalling device must be wired properly.
10) Further installation is identical with the new FLEX, i.e. the same as the procedure
detailed in chapter 4.
