GFS Differential Air Pressure Switch Installation
Electrical
Connect Insert a conduit tube with 1/2” thread and tighten with a torque of 2.5 Nm.
Assemble flex- and conductors accordingly.
Note: This is a low voltage circuit. Do not run low voltage conductors with high voltage
conductors.
Make and verify connections per supplied system wiring diagram. The connections are
intended for 0.25" (6.3 mm) crimp-type sockets. The switch (P) in the pressure switch is
designed as a change-over contact. Pole 3 (COM) closes to pole 2 (NO) at increasing
pressure and to pole 1 (NC) at decreasing pressure.

Switching Pressure Adjustment
Caution! Make absolutely sure that no voltage is applied to the electrical connections,
before any settings on the pressure switch are carried out.
Set the desired pressure, which trips the switch at decreasing pressure, on the setting
button using a screwdriver. When the pressure falls, the switch returns into its resting
position, as soon as the pressure falls below the set switching differential. Place the
cover and screw it to the pressure switch. Do not operate the system until the housing is
closed. Check the trip and reset pressure by slowly increasing and decreasing pressure.
Switch should be adjusted so that it makes upon vent fan enabling and opens when fan
stops.
