General Information; Use With Salt Water - Task Force Tips ZN Series Instructions For Installation, Safe Operation And Maintenance

2.0 GENERAL INFORMATION

The Task Force Tips ZN, ZM and Masterstream nozzles are deluge nozzles with clean far reaching straight stream. They are
adjustable from straight stream to a dense fog pattern. Their rugged construction is compatible with the use of fresh water as well as
fi re fi ghting foam solutions. A summary of each nozzle's characteristics is shown in the tables below.

NOTES ON TABLES:
• 2 ½ inch NH female threads are standard. Other threads and coupling sizes can be specifi ed at time of order.
• ZM & ZN series nozzle are hardcoat anodized ANSI 356 aluminum.
• Masterstream series nozzle is constructed of hardcoat anodized 6061-T6 aluminum.
• Masterstream series nozzle is also available in automatic pressure control models. See catalog for details.
• Temperature Rating: -25°F to 135°F (-32° C to 57°C) for ZN and Masterstream nozzles;
-40°F to 135°F (-40°C to 57°C) for ZM nozzles.

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.

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 665 LBS (1250 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, refi ned
products.
• Applying foam over a low conductivity liquid of suffi cient 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 • Distance from the nozzle to the line or equipment
Size of the stream • Whether the stream is solid or broken
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.
The nozzle may become damaged if allowed to freeze while containing water. Always drain after
use to avoid damage and possible loss of use.
