09System Mounting
IMPORTANT NOTESThe system should be mounted at EYE LEVEL.
Care must be taken to ensure the system and all protruding components are clear of all enclosure accesses (doors and covers) and conduit, pipe, tubing or cable entries.
LH, RH, TM, BM and WM configurations are intended for mounting adjacent to the protected enclosure.
LH, RH, TM & BM configurations are also suitable for 2" schedule 40 pipe mounting.
Determine the mounting configuration of your system using the diagrams on pages 9 & 10.
Remove and save the manila envelope (containing the enclosure warning nameplate) which may be taped to the outer surface of the mounting flange.
Although all purge systems are factory tested and calibrated, we strongly suggest a bench test of basic functions prior to installation.

IMPORTANT NOTE: NFPA 496 requires the use of an alarm or an indicator to detect the loss of safe enclosure pressure. In addition, the NFPA 496 requires that if an indicator alone is utilized, a protective gas supply alarm must also be installed between the last valve in the protective gas supply and the protected enclosure. Therefore, the protective gas supply to all LPS style systems must be equipped with the above mentioned protective gas supply alarm. Exception: systems utilizing either an EPSK or GPSK enclosure pressure loss alarm switch accessory will satisfy the above mentioned NFPA requirement.
