9.3 IMPULSE TRIGGER VALVE SYSTEM NOZZLE COLORED PISTOL GRIPS
The TFT Impulse Trigger Valve System nozzles are supplied with black pistol grip covers. The pistol grip covers are available from TFT
in various colors for those departments wishing to color code the nozzle to the discharge controls. Follow the steps below to change the
pistol grip cover.
1. Orient nozzle vertically. This keeps the dampening fluid in the pistol grip from spilling
out.
2. Remove the Cap. (1/2 in square drive) The Adjusting Screw (3/16 in Allen Wrench) may
need to be turned in or removed to be able to engage the square pocket in the cap.
Note the position of the Adjusting Screw before moving it.
3. Slide off the Pistol Grip Cover and install a new one. Be sure the Pistol Grip Cover’s
internal rib is toward the back of the nozzle.
4. Reinstall the Cap until it bottoms out on its shoulder.
5. Reinstall or reposition the Adjusting Screw if it has been moved from its original
location.
6. Flow nozzle to check performance of slow closer. Adjust as needed.
