UNIVERSAL PRESSURE SWITCHES – INSTRUCTION SHEET
INSTALLATION
WARNING: Make sure that the replacement pressure switch does not exceed the compressor manufacturer’s
air pressure specifications.
See wiring diagram on inside cover of the replacement pressure switch.
1.
Determine what ports on the replacement pressure switch will be in use. Plug those ports that will not be in
use. Add pipe dope to the port plugs. Do not attach accessories at this time.
2.
Make sure the pressure switch is in the off position.
3.
Attach the pressure switch to the compressor, making sure that the Unloader Valve is in the same position as
the original pressure switch unloader valve. The pressure switch unloader valve rotates for ease in
installation. Re-connect the unloader valve tubing. If the unloader valve was not previously in use, simply
ignore the unloader valve on the pressure switch.
4.
Put pipe dope on all male threads. We do not recommend using Teflon tape, as particles of the tape tend to
clog filter screens and regulators.
5.
Remove pressure switch cover and connect any accessories to the pressure switch (Gages, Regulators, and
Safety Valves.)
6.
Re-insert the cable from the motor to the pressure switch.
7.
Move black and white wires out of the way and attach the green ground wire to the frame, using either hole in
the frame.
8.
Attach black wire to T1 terminal. If using screw type terminals, remove quick connect terminals from the
replacement pressure switch.
9.
Attach white wire to T2 terminal.
10. Reconnect line power cable to the pressure switch.
11. Attach green ground wire to second hole in the frame.
12. Attach black wire to terminal L1 (same side as black wire from motor cable).
13. Attach white wire to terminal L2 (same side as white wire form motor cable).
14.
Tuck wires under cover and screw cover back on the pressure switch.
WARNING: NEVER OPERATE COMPRESSOR WITHOUT PRESSURE SWITCH COVER IN PLACE
