4.0 INSTALLATION
1. Remove cap screw and washer in end of valve
body nearest port having pressure measured.
(See Figure 3, No. 1).
2. Coat o-ring on pressure switch mounting
surface with hydraulic oil. (See Figure 3, No. 2).
3. Install pressure switch on end of valve using
cap screws provided with switch; torque to 3
FT-LBS (4-N-M). (See Figure 3, No. 3)
NOTE: The switch may be oriented in either
direction parallel to the length of the valve. Din
plug may be oriented every 90°.

5.0 PRESSURE SWITCH ADJUSTMENT

1. Loosen lock nut counter-clockwise.
2. Using 10mm wrench turn adjustment screw
clockwise to increase or counter-clockwise to
decrease pressure.
3. Tighten lock nut (3 FT-LBS [4-N-M]) clockwise
while holding pressure setting with wrench.
(See graph, Figure 4, for settings [graph is
only a rough guideline; to find switching points
more precisely use a pressure gauge]).

Adjustment Distance – "S" [M]
Note: Adjustment distance "S" in Figure 4 is
measured from end of adjustment screw to the
switch body (where lock nut snugs up against).
6.0 MANIFOLD MOUNT SECTION
Necessary dimensions for manifold mount hole
are contained in Figure 5.

7.0 ELECTRICAL CONNECTION

For pumps equipped with an electrical enclosure,
the electrical cord for the pressure switch plugs
directly into the left side of the enclosure. The
correct receptacle for the pressure switch is
illustrated on the enclosure lid. Remove the cover
and jumper wire from the receptacle before
attempting to plug the cord in. The cord end is
keyed such that it goes into that one receptacle
only. Do not force the cord end into the
receptacle. Check to insure that you have chosen
the correct receptacle, and that the jumper wire
has been removed from that receptacle.
