Installation Installation Place of installation Note! Ambient conditions! In the event that the dryer is not installed under suitable ambient conditions, the ability of the device to condense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and in a loss of efficiency and performance of the dryer.
Installation Installation plan - A - Air compressor Aftercooler Condensate separator Prefilter Bypass group Dryer Compressed-air tank - B - Final filter Bekomat condensate drain Installation type A is recommended when the total consumption corresponds to the throughput rate of the compressor. Installation type B is recommended when the air consumption constantly varies, with peak values which considerably exceed the throughput rate of the compressor.
Installation Connection to the compressed-air system Danger! Compressed air! All works must only be carried out by qualified skilled personnel. Never work on compressed-air systems which are under pressure. The operator or the user must ensure that the dryer is never operated with a pressure exceeding the maximum pressure value indicated on the type plate.
Installation Electrical connections Danger! Supply voltage! The connection to the electric mains should only be carried out by qualified skilled personnel and must correspond to the legal provisions in force in your region. Prior to connecting the device, please check the type plate to avoid exceeding the indicated values. The voltage tolerance is +/- 10%.
Start-up Start-up Preliminary stages Note! Exceeding of the operating parameters! Ensure that the operating parameters comply with the nominal values indicated on the type plate of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature etc.). Prior to delivery, this dryer was thoroughly tested, checked and packed. Please verify the reliability of the dryer during the initial start-up and check the perfect functioning during the first operating hours.
Shut down and restart RA 330-960 eco 3phase - during short-term inactivity (max. two to three days), it is advisable to leave the dryer and the control panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the dryer to wait two hours, until the crankcase heater of the compressor has heated up the oil in the compressor.

Technical description 11.2 Functional description Operating principle – All dryer models described in this manual function according to the same principle. The hot and moisture-loaded air is led into an air/air heat exchanger. Afterwards, the air flows through an evaporator, which is also known as an air/refrigerant heat exchanger.
Technical description 11.4 Refrigerating compressor The employed refrigerating compressors are constructed by leading manufacturers. The hermetically sealed construction is absolutely gastight. The integrated safeguard protects the compressor against overheating and excess current. The protection is automatically reset as soon as the nominal conditions are reached again. 11.5 Condenser The condenser is the component in which the gas coming from the compressor is cooled down, condensed and liquefied.
Technical description 11.9 Hot-gas bypass valve At partial load, the valve directly returns a part of the hot gas to the suction line of the refrigerating compressor. The evaporation temperature and the evaporation pressure remain constant. ADJUSTMENT The hot gas by-pass valve is adjusted during the manufacturing testing phase. As a rule no adjustment is required;...

Technical description 11.12.4 Indication of a Service Warning A service warning is an exceptional event and requires the attention of the operator/service technician. The dryer will not be stopped. When a service warning is active, the Led flashes. When a service warning is no longer active but not reset yet (so it has been stored) Led is continuously on.
Technical description 11.12.6 Operation of the Service Warning / Alarm signal The DMC 51 is equipped with a 12Vdc signal (max 15 mA) to indicate service warning or alarm conditions. Dryer is switched on, no service warning and no alarm (active and not yet reset) are indicated.
