Sprinkler systems place a large quantity of water in the dust collector when activated. Provide adequate drainage to remove water. Excess water weight can cause the leg structure to collapse.

Optional fire control sprinklers are available for all models operating under negative pressure. Donaldson Torit supplied sprinklers require a minimum of 15 psig water pressure to each module. The volume of water discharged per sprinkler head is 20 gallons per minute.

Consult with local authorities when installing fire control systems on dust collection equipment.

1. Open the front access doors to access the sprinkler tap located in the dirty-air plenum.

2. Apply pipe sealant to the threads of the pipe reducer located on the sprinkler assembly.

3. Thread the sprinkler assembly onto the 1-inch diameter sprinkler tap.
