CTA Instruction Manual MPE READ THIS MANUAL ATTENTIVELY BEFORE INSTALLING OR USING THE APPLIANCE ! These symbols inform you about dangers and the measures to be taken to avoid them. The comments in bold type emphasise the key points to observe to ensure you use your drier correctly. 1 Introduction 1.1 Principle Your Mastéria drier dries air by refrigeration. Hot, wet compressed air entering the Mastéria drier is cooled by an exchanger down to the programmed dew point temperature.
CTA Instruction Manual MPE 2 Safety Everyone involved in installing, using and servicing Mastéria dryers is concerned by this manual and must have read and understood the instructions given below. ! Danger of electric shock and burns: every badly connected or misused electrical appliance is dangerous. For your personal safety and that of all the people who will approach this appliance, rigorously follow all the security instructions given in this manual.
CTA Instruction Manual Take all appropriate precautions when welding or carrying out any other repairs which release heat, flames or sparks. Protect all components in the vicinity with non-flammable material. Drain lubrication system parts or components containing oil if working close to them. Never use a naked flame as a light to inspect the drier. MPE If non-flammable chlorinated hydrocarbons are used for cleaning, take all safety precautions to prevent injury from the toxic vapours released.
CTA Instruction Manual MPE 3 Installation ! The installation procedures described in this chapter must only be executed by qualified personnel. The following procedure must be scrupulously respected or the safety of all staff could be at risk. 3.1 Inspection Immediately after unpacking the drier, check that it is undamaged. If necessary, make a damage claim to the carrier who delivered the equipment. ! Never install or use an appliance damaged during shipment. 3.
CTA Instruction Manual They must act directly on the tank with no intermediate position and possess a discharge capacity higher than the quantity of air inlet to the tanks, calibrated and sealed at the safety pressure of your network which must always be under 20 bars. 7. Connect the compressed air to be treated to the drier inlet (lower port) with pipes which do not place stresses and strains on the appliance. 8.
CTA Instruction Manual MPE 4 Use 4.1 First start up ! Only start up the drier once you have thoroughly tested all the hydraulic, refrigeration and electrical connections. 1. Close the isolating valves on the drier and open the by-pass valve. 2. Check that the master switch is set to O. 3. Start the air compressor 4. Set the master switch to I. The drier digital display panel comes ON. 5. The refrigerating compressor and the fan start after a 2 minute safety time-out. 6.

CTA Instruction Manual MPE 5.3 Changing purging duration General Comments Condensate purging automatically starts every 5 minutes for duration adjustable from 1 to 20 seconds. The factory setting meets nominal drier operation conditions. However, you may have to: • Increase the duration of purging if the temperature of the air to be treated is higher than nominal and if you find liquid phase water downstream from the drier.

CTA Instruction Manual MPE MPE 010 to 125 1. Replace the upper panel by sliding it forwards to engage the lock tabs. Screw up the rear screws of the upper panel. Otherwise, replace the front panel by sliding it downwards to engage the lock tabs. Screw up the lower screws of the front panel. Then 2. Unlock the power supply cut-out switches. 3. Unlock the upstream and downstream valves and the by-pass valve. You can now start up the drier and return it to the network. 6.
CTA Instruction Manual MPE 7.2 Solenoid valve maintenance * General comments The solenoid valve must always be protected by a filter to ensure that solid particles do not prevent it from opening and closing correctly. If particles do get through the filter and cause faulty operation of the solenoid purge valve, it is must be dismantled and cleaned. Procedure 1. Close the manual valve on the purging line (see refrigeration/pneumatic circuit diagram) 2. Disconnect the solenoid valve power supply 3.
CTA Instruction Manual MPE Important: • • This schedule is based on average operating conditions. In some cases it may be necessary to increase maintenance frequency. Clean the condensate purge filter on the purging system 1 week after start-up. *You must comply with the recommendations at the beginning of this chapter. 9 Alarm When temperature sensor is broken or short circuited, the first digit point (see diagram § 5.1) will blink and the display show value ‘’00’’.
CTA Instruction Manual MPE 11 Troubleshooting PROBLEM A. Dew point too high CAUSE SYMPTOM REMEDY Compressed air temperature too high. The digital display panel indicates a value > 4C° permanently Return the air inlet temperature to within the limits. Compressed air flow rate too high. Ditto Correct the air flow rate to within the limits of the drier. Compressed air pressure too low. Ditto Correct the pressure to within the limits. Ambient temperature Too high.
CTA Instruction Manual PROBLEM E. CAUSE All the LEDs on the electronic board are OFF as if the power supply had failed. Repair or replace the fan. Press the red re-set button on the pressure controller. Ambient temperature Too high. Ambient air temperature conditions higher than maximum authorised value Return the ambient temperature to within the limits by, for example, increasing room ventilation. Press the red re-set button on the pressure controller.
