Installation; Cable And Hose Routing; Accessories - Nederman FlexFilter EX Manual De Instrucciones

When calculating for foundation or supporting struc-
ture the following factors should be taken into consid-
eration .
• Total weight of the FlexFilter EX with accessories
(see "Technical data") .
• Traction forces generated by explosion relief vent-
ing (for models with relief venting only) .
• Max weight of the collected material .
• Possible wind load .
Each of the anchor bolts securing the FlexFilter EX,
must withstand traction forces of 12 kN vertically and 5
kN horizontally.
Recommended bolts for concrete are Hilti HDA-PF
22-M12x125/30 or equivalent . If expansion bolts are
to be used, the concrete foundation must be prepared
according to bolt recommendations .
The FlexFilter EX should not be installed close to heat
sources or hot surfaces .
If installed outdoors, it is recommended that the Flex-
Filter EX is covered top side to protect from snow/rain
or other falling debris .
