• Make sure the O-ring and the groove are clean and in good condition.
• Remove the G
1⁄8
plug from the port on the fl ange, the regulator, or the valve
with a 3 mm hex key wrench.
• Clean the mounting surface around the port.
• Make sure that the surface is clean and in good condition.
• Mount the switch onto the port using the M4 x 20 mm socket head screws.
• Make sure that the O-ring is located in the groove.
• Tighten the screws snugly, not exceeding 22 lb-in.
• Perform a leak test to verify that no leakage occurs around the O-ring.
• No venting is required with the gas pressure switch. It has a built in restricting
orifi ce.
Setpoint Calibration
The setpoint dial of the gas pressure switch is factory calibrated with
increasing pressure. Due to hysteresis the switch will actuate at a slightly
lower point when the pressure decreases.
Adjusting the Setpoint
• Disconnect all power to the switch before beginning to prevent electrical
shock and equipment damage.
• Remove the clear cover from the switch.
• Adjust the setpoint to the desired operating pressure by turning the dial
clockwise to increase the setpoint or counterclockwise to decrease it.
• Turn dial until the white arrow on the yellow dial face is at the desired
operating pressure.
• Aft er adjusting the setpoint for normal operation, check to see that the
gas pressure switch operates as intended.
• Use an accurate pressure gauge connected upstream from the switch
to measure the actual pressure.
• Replace clear cover.
Automatic Reset
The NC contact of the gas pressure switch breaks when pressure rises to
the setpoint. It makes automatically when pressure falls below setpoint.

Wiring
• Disconnect all power to the pressure switch before beginning the wiring to
prevent electrical shock and equipment damage.
• All wiring must comply with local electrical codes, ordinances, and regula-
tions.
• Do not exceed the switch ratings given in the specifi cations and on the switch.
• Remove the clear cover from the switch.
• Route the wires through the conduit connector.
• Connect the wiring to the appropriate screw terminals on the terminal strip.
• These switches require a conduit seal to meet 4.1.3.2 of NFPA 86 20
11.
