SETTING COMPRESSOR PRESSURE

Setting Pressure Switch in the Compressor

Set pressure switch only when pressure is applied to the system. A gauge must be

fitted in order to check pressure.

(1) Unscrew stop “A” with screwdriver.

(2) The maximum switching pressure must be adjusted first, this is done by rotating

knob “B” (clockwise raises the pressure).

(3) To adjust minimum switching pressure, depress knob “B” and rotate as before.

(4) Screw in stop “A”.

(5) Enter cut-in and cutout valves on label.

Remote Controls

 RC/1 is a rotary switch.

 RC/2 and RC/3 are 3 button controls.

Remote controls can be fitted to each compressor. When transferring control from

the front panel of unit to the remote control device, it is a good practice to set the

compressor panel control to the hold position. When the remote circuit is switched

back to the compressor panel circuit the mast will then be on hold and therefore

maintain its position.

The RC/2 will normally be used for DC operation of AC powered compressor units.

Please note that a separate power supply unit is installed within the compressor to

supply a DC output.

The RC/3 is a standard remote control similar to the RC/1 but with 3 button

operation.
