MOUNTING AND INSTALLATION
The Model ADPS is typically mounted in an upright position on a flat surface by two 1/4" screws
through the mounting flanges on the base or by two 1/4-20 screws into the back of the base.
See Fig. 1 for mounting dimensions. Locate the switch where vibration, shock and ambient
temperature fluctuations are minimal. To avoid damage to the switch, always hold a wrench
on the pressure connection hex when tightening pressure connections. Never tighten the
pressure connection by turning the switch housing into the fitting.

WIRING
Use properly rated temperature supply wire for the anticipated service temperature. Make all
electrical connections in accordance with the National Electrical Code and local regulations.
A wiring check may be performed by manually actuating the switch actuator on the side of the
snap-action switch inside the enclosure. (See Fig. 3)
NOTE:
Do not loosen or remove the two (2)
screws that secure the switch to the switch mounting bracket.
