4230 Series (Remote Operation)
The nozzles in the 4230 remote family can be connected
to a controller, such as the SPR-2000
™
controller,
so that each nozzle has its own Liquid , Atomize air, and
On/Off air supply. The compressed air will turn the nozzle
on and off. The liquid and atomize air are used to create
the nozzle spray.
1. Connect the clear nylon tubing to the Liquid port of
the nozzle. Route the tubing to the valve stack. Ensure
that there is no fluid pressure on the valve stack, and
plug a 90 degree male quick disconnect fitting into the
appropriate female quick disconnect of the valve stack.
2. Remove the nut from the male quick disconnect and
trim the tube length such that it will just slide over the
barb on the fitting.
3. Slide the nut onto the hose and then push the tube
onto the barb of the quick disconnect. Tighten down the
nut with a 3/8” wrench. Repeat for the remaining valve/
nozzle combinations.
