When the firefighter changes the gallonage setting on the Select-O-
Flow nozzle, a change in engine pressure will have to be made to compen-
sate for the change in hose friction loss and appliance loss. If this adjust-
ment in engine pressure is not made, the gallonage indicated by the nozzle
setting will not be produced.
CAUTION
Care should be taken when opening and closing the shutoff. Rapid
closure and/or opening may cause pressure surge or “water hammer”
which could result in equipment failure, with associated potential injury
to firefighters.
MAINTENANCE AND CARE
The Select-O-Flow series of nozzles is designed and manufactured to
give you years of trouble-free service. Since the nozzle is the firefighter's
first line of defense against the fire, it should be treated with care. It is not
designed as a battering ram, sledge hammer or forcible entry tool.
Weekly visual inspections and monthly operational checks should
ensure excellent reliability. These inspections may be done daily in active
companies. All nozzles should be flow tested before entering any hazard-
ous environment to ensure equipment is operating properly.
If the nozzle tip becomes hard to rotate (change patterns), remove tip
from nozzle and clean acme threads between the tip and center barrel.
Prior to reassembly of nozzle tip to center barrel, apply light coating of
silicone grease (Dow-Corning #7 or equivalent) to acme threads. Refer to
enclosed parts drawing for assembly and disassembly sequence. Clean
excess grease from nozzle after assembly to prevent adhesion of dirt and
ash to close clearance parts.
With a minimum amount of care your Select-O-Flow will give you
years of excellent service. If you have any further questions pertaining to
these nozzles, please feel free to call on us at any time. Thank you for
choosing Elkhart for your fire suppression needs!
