INSTALLATION INSTRUCTIONS
Installation Overview:
Installation Step 1: Mount and Wire All System Components
Warning:
It is up to the system designer to appropriately handle the open circuit
condition of the stow signal. In the open circuit mode there is no source to turn off the
stow signal load, which may lead to erroneous signal indications if not handled properly.
The stow signal is capable of sinking 250mA maximum. Exceeding this value may blow
the internal fuse and the stow output will no longer be able to provide a ground.
Important:
Most test lights draw in excess of 1A.
Monitor Mounting –
 4”-150# Flat Faced Flange: Attach 4”-150# ANSI pattern
companion flange to water supply pipe so that the bolt
pattern will allow the monitor to be installed in the straight
ahead position. Alignment is correct when the straight
ahead position is centered between adjacent flange holes.
Attach monitor inlet flange to companion flange on water
supply pipe with eight (8) 2½” 5/8-11 UNC grade 5,
carbon steel or stainless steel bolts & nuts. Seal flange joint
with gasket, or suitable flange sealant. Most wafer type
butterfly valves have seats that serve as flange gaskets, and
separate gaskets or sealant is not required. Apply Loctite
242 or equivalent to bolt threads before tightening nuts.
Torque to 60-70 ft-lbs.
Warning:
When installing the monitor on a raised face companion flange, it is critical
that the bolts be tightened uniformly to prevent misalignment of the monitor relative to
the flange or valve. If the monitor becomes misaligned, the base flange will fracture and
fail when the bolts on the “high” side are tightened.
