INSTALLATION
Note: Make sure that port o-rings are correctly placed inside o-ring groove.

1. Affix solenoid valve to actuator and tighten screws.
2. Disconnect solenoid wire hood.
Note: Terminal designation (1) Positive (2) Neutral (3) Ground.
3. Energize solenoid valve several times and test for leaks and proper operation.
Note: Solenoid nut should be hand tight.

MANUAL OVERRIDE
The Proximity solenoid valve comes equipped with a manual override. A small push
button located between the valve body and the coil allows for the overriding of the
solenoid if necessary. The normal position for the button head is in a raised
position. Rotation of the button in the counter clockwise direction will manually
override the solenoid and lock the solenoid in the disengaged position until the
screw head is returned to its original position.

Solenoid Classification
The Proximity solenoid valve is designed to IP65 standard.

NEMA 4, 4X: Watertight and dust tight - indoor and outdoor. Protects against
windblown dust, rain, splashing water and hose directed water. Also corrosion
resistant.

WIRING
Wire in accordance with the National Electrical Code and local regulations.

To aid in the wiring, the solenoid on the SN may be rotated 360°. For unwired
models it is recommended to use 18 AWG copper wire rated at 90°C or greater.

Wiring the SN with DIN connector. See Figure 3.
1. Remove center screw and pull wiring assembly from the body.
2. Remove gasket and place small screw driver in slot to pry out the terminal block
from the cover.
3. Thread wire through the gland nut, gland gasket, washer and connector cover.
4. Connect wires to proper terminals on the terminal block.
5. Snap terminal block back into the cover. The connector cover may be rotated in
90° increments to position the cable entry as needed for the application. Reinstall
the center screw and screw back into the solenoid body.

MAINTENANCE/REPAIR
Upon final installation of the Series SN, no routine maintenance is required. The
Series SN is not field serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
