    MSC4000 - MSC15000 USER GUIDE Start Up Procedure Preliminary Checks Before starting the dryer, verify that the compressed air valves are closed so there is no airflow through the dryer, the dryer supply voltage is correct, and there is sufficient water supply to the unit (water cooled).
  • Page 8 MSC4000 - MSC15000 USER GUIDE • SLOWLY close the air bypass valve until the dryer is under an air load. Note: Fast opening of air valves could damage the heat exchangers. At this time, complete the following start up form. Note: The refrigerant compressor may require additional oil added.

  • Page 29: Mrd Drains

    MSC4000 - MSC15000 USER GUIDE MRD Drains The MRD is designed to reliably discharge condensate while preventing the loss of valuable compressed air. Rising condensate in the sump actuates a mechanical float switch operating the drain valve. The drain valve remains open until the sump is empty. The MRD only discharges condensate. No compressed air is wasted.

  • Page 31: Routine Maintenance

    MSC4000 - MSC15000 USER GUIDE Routine Maintenance This section covers the various components that require periodic maintenance and/or replacement. Coalescing Filter Element The coalescing filter element should be check Biannually. On units with the standard control panel, check the pressure drop across the unit by using air pressure gauges upstream and downstream of the dryer using the closest possible gauges to the dryer.
  • Page 32 MSC4000 - MSC15000 USER GUIDE The refrigeration pressure switches should be checked monthly to ensure that they are adjusted to the proper settings. Please refer to the applicable electrical drawings for your unit. Compressor Oil Level The oil level in the compressor should be checked daily. The refrigeration system should never need oil unless the system is leaking or has been recently repaired.

  • Page 33: For The Refrigeration Technician

    This section is a list of hints and instructions for the skilled serviceman and relating specifically to the Parker Airtek Dual Mode refrigeration system. Recharging Dryer - Refrigerant, Oil and Dryers Refer to the dryer information tag on the front of the unit for the approximate charge needed for each unit. The relatively large charge is needed because of the flooded-shell evaporators.

  • Page 34: Refrigerant Control Valves

    Unloader solenoids operate with greater differentials and so are more likely to fail. Parker Airtek uses valves with a rated life of more than two million operations. When they finally wear out, the usual symptom is failure to close. The valves can usually be restored by installing a diaphragm repair kit available from Parker Airtek or the valve’s local distributor.

  • Page 35: Factory Assistance

    A short call may save a long troubleshooting experience. Instructions for Ordering Parts All parts orders should be placed with your Parker Airtek Dealer. Should you not know the dealer in your area, contact Parker-FAF. When ordering parts, specify dryer model and serial numbers to insure receiving proper parts (see nameplate on unit).

  • Page 36: Diagnostic Codes

    MSC4000 - MSC15000 USER GUIDE Diagnostic Codes Diagnostic Code “E1” Shutdown on Open Dew Point Circuit The dew point sensing circuit is devised of three parts. The dew point probe, cable and digital control board. The combination of these parts measures the air temperature leaving the evaporator.

  • Page 37: Diagnostic Code "E3" Shutdown On High Super Heat

    MSC4000 - MSC15000 USER GUIDE Should the display on the digital control board change from a “E2” to a “E1”, the short is in the dew point probe. Replace it. If the display continues to show a “E2” disconnect power to the unit and locate the connection between the cable and digital control board, and disconnect it.

  • Page 38: Diagnostic Code "E4" Shutdown On Freeze Protection

    MSC4000 - MSC15000 USER GUIDE D) Expansion Valve Stuck Closed Test by applying heat (hair dryer) to TXV sensing bulb located just after the flood level control for about 30-45 seconds. This should cause the unit to flood back and lower the super heat. To check this, take a temperature reading on the suction accumulator, it should be extremely cold, if it is not, your expansion valve is stuck closed.
  • Page 39 MSC4000 - MSC15000 USER GUIDE If you have determined that the valve is not getting energized electrically, then the valve may have malfunctioned mechanically. Determining this is relatively easy. When the dryer is refrigerating and the Power Saver Active light is off we know that the unloader solenoid should be closed.

  • Page 40: Diagnostic Code "E6" Shutdown On Low Suction Psi

    MSC4000 - MSC15000 USER GUIDE Diagnostic Code “E6” Shutdown on Low Suction PSI If the suction pressure of the refrigeration system drops 20 psi (1.4 bar g) or lower it will break contact through the low-pressure switch. This in turn breaks power to the refrigerant compressor for protection.

  • Page 41: Diagnostic Code "E7" Shutdown On High Head Psi

    MSC4000 - MSC15000 USER GUIDE a) You need to first check the coil of the liquid line valve to ensure that it is functioning. The easiest way to verify if the coil is energized is to take a screwdriver and touch it to the screw or post on the top of the coil.
  • Page 42 MSC4000 - MSC15000 USER GUIDE High Ambient - Take a temperature reading at the condenser, anything over 100ºF (38ºC) is no good. High Compressed Air Flow - Compare HP or CFM and run time to the rating of the dryer. High Inlet Compressed Air Temperature - To test take a temperature reading with an infrared temperature gun on the inlet pipe.

  • Page 43: Diagnostic Code "E9" Drain Shutdown

    MSC4000 - MSC15000 USER GUIDE You need to first check the coil of the liquid line valve to ensure that it is functioning. The easiest way to verify if the coil is energized is to take a screwdriver or a piece of metal and touch it to the screw or post on the top metal to the screw or post.
