d) 1-SOL re-assembly instructions:
1) Valve body:
1.1) Parts must be replaced in the order and orientation shown in the exploded view
Diagram 5
in
Section VII
.
1.2) To assemble the diaphragm assembly, torque the lock nut with input torque of
45-55 in-lbs. Apply one (1) drop of appropriate thread locking liquid to the lock
nut threads.
1.3) When assembling the diaphragm assembly to the valve body, the diaphragm
tab should be positioned as follows:
1” NPT port size - the diaphragm tab is located over the outlet port of the
body.
1-1/2” NPT port size - the diaphragm tab should be located 30 degrees
counter-clockwise from the outlet port when viewed from
the diaphragm side.
Ensure the diaphragm bolt holes and flow holes line up with the appropriate
bolt and flow holes in the valve body.
1.4) Replace valve cover and tighten cover screws with an input torque of 110-150
in-lbs.
1.5) Install the snubber, plunger wave washer, stop, seal retainer and plunger
return spring in the sleeve. Install flange seal and tighten at sleeve flange using
wrench nut with an input torque of 130-150 in-lbs.
2) Solenoid:
2.1) With the solenoid repositioned on the sleeve, slide washer over sleeve, replace
nut, and tighten nut with an input torque of 45-53 in-lbs.
NOTE:
Never apply electricity to a solenoid valve without ensuring that the
solenoid is properly installed on the valve sleeve. The resulting high in-
rush of current can result in an electrical short in the solenoid.
2.2) Rewire and connect valve power leads to 1TB5 (#6R) and 1TB2 (#2W3) for
normal operation. Refer to Electrical Schematic
Diagram 4
in
Section VII
.
2.3) Tighten conduit union to complete installation.
