5.1.2 FLUSHING DEBRIS
WARNING
Large amounts of debris may be unfl ushable and can reduce the fl ow of the nozzle resulting in
an ineff ective fl ow. In the event of a blockage, it may be necessary to retreat to a safe area.
Debris in the water may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach, and
reduced fl ow. Debris can usually be cleared by moving the shaper to the wide fog position at high fl ow for a couple seconds and then
resuming operation. If debris remains trapped in the nozzle;
1) Shut off fl ow to the nozzle.
2) Move the stream shaper to the wide fog position.
3) Unscrew baffl e retaining screw using a 3/16” allen wrench.
4) Remove baffl e retaining screw, spring washer, baffl e, and seat.
5) Remove debris. Flow water to fl ush if necessary.
6) Apply blue loctite to screw threads. Reinstall seat, baffl e, spring washer, and baffl e retaining screw (make sure seat is
centered on baffl e and orient spring washer as shown below)
7) Torque baffl e retaining screw to 180 in-lb (20 N m)
5.2 ASPIRATING SLEEVE
The Bubble Cup nozzle is capable of producing aspirated foam as well as a conventional straight stream and wide protective fog
pattern. The Bubble Cup functions just like a fog nozzle when the aspirating sleeve is in the retracted position as in fi gure A below.
To use the aspirating feature of the Bubble Cup, grip the aspiration sleeve and pull it forward to it’s extended position.
In the extended position fog patterns are disabled in order to aspirate foam. Adjusting the shaper’s position will control aspiration and
reach. The aspirator may be gripped and pushed back to it’s retracted position if fog patterns are needed.
