NSTRUCTIONS
1. 3” NPT Base
Apply an appropriate thread sealant to the 3” NPT nipple. Thread the monitor base
onto the nipple. Ensure that the alignment of the fixed monitor base for the 8500-03X
and 8593-03X/294-11REV.06X is in the correct position for access to the left/right
hand wheel. Alignment for other monitors is not critical as the monitor is capable of
360º continuous rotation.
2. 3” 150# Flat Faced Flange
Attach a 3" 150 lb. class ANSI pattern companion flange to the water supply pipe.
Elkhart Brass recommends using the 81315001 Companion Flange Kit. Ensure that
the alignment of the fixed monitor base for the 8500-03X and 8593-03X/294-
11REV.06X is in the correct position for access to the left/right hand wheel. Attach
the monitor inlet flange to the companion flange on the water supply pipe with four (4)
5/8-11 UNC grade 5 carbon steel or stainless steel bolts, 2-1/2 inches long, with nuts.
If a wafer type butterfly valve is installed between the monitor and the companion
flange, required bolt length will be 4-1/2 inches. Seal the flange joint with a 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
to the bolt threads, then thread on the nuts, and torque them to 60-70 ft-lbs uniformly
in increments of approximately 20ft-lbs.
3. 4” 150# Flat Faced Flange
Ensure that the alignment of the fixed monitor base for the 8500-03X and 8593-
03X/294-11REV.06X is in the correct position for access to the left/right hand wheel.
Attach 4" 150 lb. class ANSI pattern companion flange to water supply pipe. Elkhart
Brass recommends using the 81317001 Companion Flange Kit. Attach monitor inlet
flange to companion flange on water supply pipe with eight (8) 5/8-11 UNC grade 5
carbon steel or stainless steel bolts, 2-1/2 inches long, with nuts. If a wafer type
butterfly valve is installed between the monitor and the companion flange, required
bolt length will be 4-1/2 inches. 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 to bolt threads,
then thread on nuts, and torque to 60-70 ft-lbs uniformly in increments of
approximately 20ft-lbs.
Warning:
When installing monitor on a raised face companion flange or butterfly
valve, it is critical that bolts be tightened uniformly to prevent cocking of the monitor relative to the
flange or valve. If the monitor becomes cocked, (see Figure 1) the monitor cast flange base will
fracture and fail when the bolts on the "high" side are tightened.
