wrench techniques are used. The installer must use two wrenches, so that stress is not
applied to the shear portion of the valve during tightening.

Connecting Pump/Dispenser Inlet Pipes
Installation
For model 9850KXTW1, refer to
“Model 9850KXTW1 Shear Valve Configuration”
For more information, refer to
To connect pump/dispenser inlet pipes, proceed as follows:
1
To maximize the installation versatility, units are shipped without the inlet piping. The installer
provides and installs the plumbing in the lower hydraulics cabinet. Where required, use the
UL-approved sealant suitable for the applicable fuel type.
Note: For hazardous fuel applications, flexible or non-metallic pipes or hoses must not be
used within the hydraulics cabinet or the shear valve may not operate correctly during
an accident. Flexible or non-metallic pipes or hoses must not be connected directly to
the Shear Valve for DEF applications.
2
Ensure that you remove any shipping plugs or caps that may be present in pipes, shear valves,
and unions. Leaving the mounting bolts a little loose at this point will require adjustment when
you install the piping.
Notes: 1) The contractor-supplied pipe and fittings must be a 1-1/2-inch NPT Schedule 40
black iron. Flexible or non-metallic pipes or hoses must not be used within the
dispenser.
2) For Super-Hi and Ultra-Hi units, the contractor-supplied pipe and fittings must be a
2-inch NPT schedule 40 black iron. Flexible or non-metallic pipes or hoses must not
be used within the dispenser.
3
Loosely connect the union halves together (see
on
Do not use a pry (crow) bar to position the pump/dispenser over the conduit or pipes.
This can damage valves, conduit, or other parts of the unit. Do not stress the unit’s
hydraulics, mounting frame, mechanical computer, and so on, by attempting to connect
parts that are vertically too short.
