Please note: applying the Dryer for higher than standard ambient and / or air inlet temperature will derate the performance. ‡ Pressure switches are factory set and must ON NO ACCOUNT be altered from the above settings. § For voltage tolerance refer to respective schematic wiring diagram. Electrical Description Description of Components 1. "ON / OFF" Switch This switches the live side of the power supply to the circuit. All models are fitted with a rotary type cam switch. 2. Compressor (complete with control box) The compressor is a single phase type and incorporates a "start" circuit to avoid risk of a stalled motor on startup. 3. General The air cooled condenser fan will run under the control of the controller sensing the temperature in the compressor discharge line. Controller The above controller is fitted on the C series of compressed air dryers. It is used to control the fan and the hot gas valve (if fitted). It also displays the dewpoint temperature and controls the time settings for the drain valve. This time setting can be changed to suit the site requirements as follows. Note: the “TEMP IN” and “TEMP OUT” buttons are not functional on the C series compressed air dryers 1. Valve Close Time (the time the valve is closed between discharges. Variable between 1 & 20 mins) Hold the “UP” button for 15 seconds. The display will start blinking, displaying the valve close time. Press the “UP” or “DOWN” arrows while the display is blinking to change the setting. If any other button is pressed, the display will return to original display and ignore the new setting. After the new value has been set, leave the controller for 15 seconds. The display will return to the dewpoint value, and the new setting will be stored. 2. Valve Open Time (the time the valve is open to discharge. Variable between 4 & 20 secs) Hold the “CLOCK” button for 15 seconds. The display will start blinking, displaying the valve open time. Press the “UP” or “DOWN” arrows while the display is blinking to change the setting. If any other button is pressed, the display will return to original display and ignore the new setting. After the new value has been set, leave the controller for 15 seconds. The display will return to the dewpoint value, and the new setting will be stored. Wiring Diagrams To assist understanding of the electrical circuitry the following wiring diagrams are included: Model Numbers Schematic Wiring Diagram Number C9-1, C14-1, C19-1 PS1061-C-011 C31-2, C39-2, C58-2 PS1061-C-012 C92-3, C120-3, C147-3 PS1061-C-013 C175-4, C238-4 PS1061-C-014 Control of Refrigerant Discharge By international agreement, the worldwide use of certain refrigerants will be reduced in stages. To this end, listed below are suggestions on how refrigeration engineers can contribute by the discontinuing of releasing any refrigerant gas to the atmosphere. Release of refrigerant to the atmosphere is an offence under Section 33 of the Environmental Protection Act 1990. DO NOT . . . DO . . . (1) Blow off refrigerants to atmosphere. (1) Pump down into a receiver or empty cylinder using Reclaim Equipment. (2) Use refrigerants to clean coils etc. (2) Clean coils etc. using a hand brush, vacuum or compressed air. (3) Leak test using pure refrigerant. (3) Leak test using Nitrogen and just a trace of refrigerant gas. (4) Recharge before mending leaks. (4) Find and mend leaks before recharging system. (5) Dispose refrigerant gas to waste. (5) Send used refrigerant gas back for reprocessing. Note: ...
