8.0 USE OF NOZZLES
Many factors contribute to the extinguishment of a fi re. Among the most important is delivering water at a fl ow rate suffi cient to
absorb heat faster than it is being generated. The fl ow rate depends largely on the pump discharge pressure and hose friction loss.
It can be calculated using a hydraulic equation such as:
PDP = NP + FL + DL + EL
PDP
= Pump discharge pressure in PSI
NP
= Nozzle pressure in PSI
FL
= Hose friction loss in PSI
DL
= Device loss in PSI
EL
= Elevation loss in PSI

9.0 COLOR CODED VALVE HANDLE AND PISTOL GRIP
The TFT nozzle with lever type valve handles are supplied with black valve handle covers and pistol grips. The handle covers and
pistol grips are available from TFT in various colors for those departments wishing to color code the nozzle to the discharge controls.
A colored handle cover set will be sent upon receipt of the warranty card by TFT. Your department’s name can also be engraved on
the covers (see warranty card for more information).
Handle covers are replaceable by removing the four screws that hold the handle covers in place. Use a 3/32” Allen wrench when
replacing screws. Pistol grip is replaceable by following TFT instruction sheet LTT-108.
For standardization NFPA 1901 (A-4-9.3) recommends the following color code scheme:
Preconnect #1 or Bumper Jump Line
Preconnect or discharge #2
Preconnect or discharge #3
Preconnect or discharge #4
Preconnect or discharge #5
Preconnect or discharge #6
Preconnect or discharge #7
