4.0 INSTALLATION
4.1 MOUNTING THE VALVE
Screw the large coupling to a pump manifold or fi re water discharge port and tighten securely. The valve position indicator should be
clearly visible, but need not be level.
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 (2013
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.
4.2 CHANGING OFFSET OF CRANK HANDLE
When equipped with a crank handle, two offset positions are available
to adjust the swing radius of the crank and knob as shown in fi gure
4.2. The longer offset position offers reduced effort to operate the
valve. The shorter offset is available to avoid interference with other
equipment on the apparatus. To change the offset, remove two 1/4”-
20 x 1/2” button head cap screws from crank. Place crank in desired
position and replace screws. Apply Blue Loc-Tite thread locking
compound to all of the screw threads.

4.3 CHANGING COUPLING LOCK-OUT
To change a coupling from rigid to full time swivel, use a
7/32” Allen driver to back out the lockout screw until the
coupling moves freely.
To change a coupling from full time swivel to rigid, Rotate
the coupling until the lockout screw is aligned with the
Air Vent/Bleed Valve on the top of the valve body. Use
a 7/32” Allen driver to tighten the lockout screw into the
lockout divot in the elbow. Do not tighten the screw onto
the polymer bearing strip.
