4.0 INSTALLATION
Make connections to fi re hose or fi ttings on each side of the Oasis Hydrant Assist Valve
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability
to unscrew the threads and complete loss of thread engagement over time. Per NFPA 1962
(1998 edition), if dissimilar metals are left coupled together an anti-corrosive lubricant should
be applied to the threads. Also, the coupling should be disconnected and inspected at least
quarterly.
CAUTION
Male fi re hose threads are sharp and can cause injury. Be careful when around male hose
threads.
4.1 CHANGING OFFSET OF CRANK HANDLE
REINSTALL CRANK
IN THIS HOLE
IF SHORTER SWING
IS DESIRED
When equipped with a crank handle, two offset positions are available to adjust the
swing radius of the crank and knob as shown in the fi gure below. The longer offset
position offers reduced effort to operate the valve. The shorter offset is available
to avoid interference with other equipment. To change the offset, remove the two
1/4-20 x 1/2” button head cap screws from crank. Place crank in desired position
and replace screws.
5.0 USE
5.1 ATTACHING TO A HYDRANT
Attaching to a hydrant can be easily accomplished by
holding the valve by the strap and allowing it to hang as
shown. Once the coupling is partially threaded, it can be
rotated to an upright position for hose connections. Tighten
coupling when valve is in desired orientation.
5.2 HYDRANT ASSIST OPERATION
Mode 1:
Attach the inlet port marked “Hydrant” either directly to a hydrant, to a supply line connected to a hydrant or to a supply line
1.
connected to the discharge of an assist pumper.
Attach one end of a supply hose to the port on the valve marked “TO FIRE” and the other end to the intake port of the attack
2.
pumper.
Rotate the crank on top of the valve clockwise until the crank stops.
