WSO 25-1 Sprinkler Installation

the primary filter.
2. Remove the 1/2-in pipe plug from sprinkler tap.
3. Apply pipe sealant to the sprinkler threads.

Each sprinkler requires a 1-in
supply line at 20 to 60 psig water
pressure.

Thoroughly clean any collected
coolants or material from the
collector prior to drilling to reduce the risk of
combustion. Failure to comply may result in

adjacent to the HEPA/95% DOP if so equipped.
7. Re-install top exhaust panel and plumb the water
supply to the ½-in pipe plug.
