tape).

nozzle body into the fitting.

Mounting the DCM style nozzle with gasket (optional)
The nozzle must be located 1' from the top of the enclosure in order to achieve proper distri-
bution of agent. The DCM nozzle is provided in either 1/2" NPT or 3/4" NPT thread on the inlet
and outlet. With proper installation material, the nozzle can be mounted from the outside in
bag houses, dust collectors, and machining centers. To prevent obstructions to the nozzle ori-
fice, the foil gasket must be used. The nozzle must be installed in the calculation area and
should never be directly over sensitive equipment or devices. Modifications to the DCM noz-
zles are not allowed.
