Flushing Debris - Task Force Tips MASTERSTREAM Series Instructions For Installation, Safe Operation And Maintenance

4.0 FLUSHING DEBRIS

Debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach and
reduced fl ow. To remove debris trapped in the nozzle:
1. Shut off fl ow to the nozzle.
2. Move the stream shaper to the wide fog position.
3. For Selectable Nozzles: Turn fl ow selector on front to "FLUSH" position.
For Fixed Nozzles: Remove nozzle to gain access.
For Automatic Nozzles: Carefully unscrew and remove the piston/cylinder.
Notes for 1000 and 1250s Nozzles:
• The cylinder is under about 25 lbs (11Kgf) of spring force. The spring must be compressed to reinstall.
• A long white push rod is part of the cylinder assembly. Pull cylinder straight out until push rod clears shaft.
Notes for 1250, 1500, 2000 and 4000 Nozzles:
• Remove the piston, return spring and cylinder
• Remove the small spring and stainless steel poppet from the center of the shaft as a unit.
4. Remove/fl ush debris.
5. Reassemble the nozzle if necessary.
Figures 5A, 5B, 5C & 5D show the pieces that are removed during the fl ush procedure of Automatic nozzles.
WARNING
©Copyright Task Force Tips, Inc. 1999 - 2011
Large amounts of debris may be unfl ushable and can reduce the fl ow of the nozzle resulting in
an ineffective fl ow. In the event of a blockage, it may be necessary to retreat to a safe area.
