7.5 Smoke Detection/Fire Suppression (OPTIONAL)
NOTE : All of th e smoke d etection/fire su ppression installation m u st be performed b y a qualified technician and in ac cordance w ith loc al, st ate, an d n ational c odes/regulation s/laws (i f any). 7.5.1 Smoke detection and fire suppression is an important aspect of the installation procedure. Fires are a common occurrence in dust collection systems and the comprehensive collection system should be designed for when a fire occurs, not if. Various systems are available for smoke detection and an even greater list of fire suppression technologies exist. Fire sprinkler systems for collectors MUST be properly connected. In most cases, this is the closest building’s fire sprinkler system. ALL smoke detection/fire suppression systems should be periodically inspected and maintained. 7.6 HEPA/SAFETY FILTERS (OPTIONAL)
7.6.1 Prior to attaching the HEPA/SAFETY housing to the exit end of the blower or silencer, apply silicon sealant to the mating flanges.
7.6.2 Insert and hand tighten the supplied bolts to secure the assembly.
7.6.3 After all bolts have been “hand tightened”, then “snug” the bolts. DO NOT OVER TIGHTEN!
7.6.4 The HEPA/SAFETY filter assembly is generally shipped with a protective cover. If so
supplied, remove the protective cover before energizing the system.
8. PRE-START UP 8.1 If not already verified in the electrical section, check rotation of fan by electrically energizing the system (turning the electrical power “ON” for a brief instant), and verify rotation. Rotation must be consistent with labeled direction on the blower.
8.2 It is suggested that new filters be properly pre-conditioned with pre-coat before start up. Please contact your Clean Air Industries Distributor for assistance.
8.3 Check the compressed air system for leaks. Confirm 80 PSI minimum air pressure (maximum 100 PSI).
Warning : Compressed air p ressure h igher t han 100 PSI can d amage t he fi lter s an d t he d u st collector’s structural integrity.
8.4 Check that the compression couplings of the pulse valves are tight.
8.5 Manually activate the reverse cleaning valves (from the Turbo pulse cleaning control). NOTE: The sound of a properly function valve is very loud (almost like a "shotgun").
8.6 Check each valve for leaks. NOTE: It is normal (and expected) for the bleed air port (on the pulse valve) to release a distinctive burst of air with each pulse.
8.7 Check the adequacy of air supply by assuring no less than 35% drop in pressure during pulse.
