5.2.2 FLUSH CONTROL
Small debris passes may get caught inside the nozzle. This trapped material will cause poor stream quality, shortened reach, and
reduced flow. To remove small debris, the nozzle may be flushed as follows:
• While still flowing water, rotate the index ring counterclockwise (as viewed from behind the nozzle) to the Flush setting. This
will open the nozzle allowing debris to pass through.
• During flush the nozzle reaction will decrease as the pattern becomes wider and the pressure drops. The nozzle operator must
be prepared for an increase of nozzle reaction when returning the nozzle from the flush position to retain control of the nozzle.
• Rotate the index ring out of flush to continue normal operations.
WARNING Large amounts or pieces of debris may be unflushable and can reduce the flow of the nozzle
resulting in an ineffective flow. In the event of a blockage, it may be necessary to retreat to a safe
area, uncouple the nozzle and remove debris.
5.2.3 SHUTOFF SETTING (TIP-ONLY MODELS)
On Tip Only models, the index ring has a shutoffsetting to stop the nozzle flow. To shut offthe nozzle, rotate the index ring clockwise
(as seen from the operating position behind the nozzle) into the “OFF” position. Rotate counterclockwise into a flow setting to open
the nozzle.
5.3 PATTERN CONTROL
TFT’s nozzles have full pattern control from straight stream to wide fog. Turning the stream shaper clockwise (as seen from the
operating position behind the nozzle) moves the shaper to the straight stream position. Turning the shaper counterclockwise will
result in an increasingly wider pattern.
Since the stream trim point varies with flow, the stream should be “trimmed” after changing the flow to obtain the straightest and
farthest reaching stream. To properly trim the stream, first open the pattern to narrow fog. Then close the stream to parallel to give
maximum reach. Note: Turning the shaper further forward will cause stream crossover and reduce the effective reach of the
nozzle.
The nozzle reaction is greatest when the shaper is in the straight stream position. The nozzle operator must be prepared for a change
in reaction as the pattern is changed.
Care must be taken to avoid dents or nicks in the nozzle tip because they can seriously affect the stream reach.
5.4 QUADRACUP NOZZLES
The QuadraCup nozzle is capable of producing aspirated foam as well as conventional straight stream and wide protective fog
patterns. The QuadraCup functions just like the QuadraFog nozzle when the aspirating sleeve is in the retracted position.
To use the aspirating feature of the QuadraCup, slide the aspirating sleeve portion of the nozzle forward. Rotation of the shaper while
the sleeve is extended provides the nozzle operator control of reach and aspiration. If an immediate wide protective fog pattern is
needed, the sleeve can be retracted instantly to its regular position.
5.0 NOZZLE CONTROLS
5.1 FLOW CONTROL
Nozzle control valves must be opened slowly to eliminate unnecessary strain on the hose and couplings, and reduce pressure
surges.
Nozzles attached to an in-service hose shall be stored in the offposition
5.1.1 LEVER TYPE FLOW CONTROL (BALL VALVE)
Models with a ball valve are shut offwhen the valve handle is fully forward. Pulling back on the handle opens the valve. TFT
recommends the use of a pistol grip for easier handling. For additional stress reduction, a hose rope or strap may also be used. This
permits more effective use and ease of advancement, while minimizing strain and fatigue. Note: In partially open positions, a ball
valve will cause turbulence and adversely affect stream quality.
5.2 INDEX RING
5.2.1 FLOW SETTING
The index ring is marked with various flow settings. Turn the index ring so the desired setting lines up with the silver indicator pin. A
spring-loaded detent is provided at each flow setting. The nozzle will flow the indicated amount when the pressure at the nozzle is
100 psi (7 bar) on standard versions, or 75 psi (5 bar) on low pressure versions.
