2.1 USE WITH SALT WATER
Use with salt water is permissible provided nozzle is thoroughly cleaned with fresh water after each use. The service life of the nozzle
may be shortened due to the effects of corrosion and is not covered under warranty.
2.2 VARIOUS MODELS AND TERMS
See figures 1A, 1B and 1C for views of the Industrial and Masterstream nozzles. The Masterstream Series Nozzle is available without
halo ring. See catalog for model numbers and details.

Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle to leak or
uncouple under pressure and could cause injury.
Do not couple aluminum to brass. Dissimilar metals coupled together can cause galvanic
corrosion that can result in inability to unscrew threads or complete loss of thread engagement.
Injury can occur from an inadequately supported nozzle. The mounting must be capable of
supporting the nozzle reaction force which can be in excess of 550 LBS (1000 GPM at 100 PSI).
Some volatile liquids can be ignited by static discharge. Static build-up can occur from:
!
Electrochemical separation of charge as water drains through low conductivity, refined
products.
!
Applying foam over a low conductivity liquid of sufficient depth to retain the charge created as
the foam blanket drains.
!
Streaming currents as water or foam is introduced into the storage tank.
Water is a conductor of electricity. Application of water solutions on high voltage equipment can
cause injury or death by electrocution. The amount of current that may be carried back to the nozzle
will depend on the following factors:
!
Voltage of the line or equipment
!
Size of the stream
