4. THE INST ALL ATION TO THE PROTECTED EQUIPMENT
FLEX is supplied assembled. The membrane is sealed and bolted to FLEX. These bolts must
be removed prior to the installation (see chapter 4.3). The installation of the device shall be
carried out according to the manufacturer's documents concerning the specific use.
4.1 THE INSPECTION OF THE FLEX BEFORE INST ALL AT ION
Immediately after the delivery and then before the commencement of FLEX installation, the
following basic checks must be performed:
✓
Check the integrity of the original packaging of FLEX.
✓
Check the integrity and flawlessness of the top coat of FLEX.
✓
Check the integrity of the membrane.
✓
Check whether no fasteners (bolts, nuts, washers) holding the top lid (cover) of FLEX
are missing.
✓
Check the integrity of the cabling.
After successful inspection, FLEX is ready to be installed. In the event of any defects or
deficiencies, contact the manufacturer or the distributor immediately.
4.2 GENERAL INST ALL AT ION GUIDELINES
A) Only lifting eyes can be used for the transport and handling FLEX. The lifting eyes of
the FLEX devices of the C and F series are firmly welded to the FLEX structure; as to
the FLEX devices of the R series, they are bolted between the FLEX body and its lid.
B) The flange of the vessel must have the same connecting dimensions as the FLEX
flange and it must be located, if possible, on the lowest possible branch extrusion,
ensuring easy installation and sufficient strength for carrying the FLEX weight. The
pressure resistance of the device must comply with the legislation relating to the
device for explosion venting and flameless explosion venting devices.
C) Both the sealing faces, both on the FLEX device and on the connecting flange of the
vessel, must be thoroughly cleaned and degreased. The material for the flange
gasket (packing) must be fit for the respective operation and meet all necessary
requirements (temperature, chemical resistance, tightness and others). The
recommended gasket is the gasket supplied by the company RSBP spol. s r.o., which
is made of EPDM for common operations. For special requirements, the gasket
meeting the special requirements of the customer can also be supplied.
