Transport Transport Check the packaging for visible loss or damage. If no visible damage can be ascertained, place the unit in close proximity to the place of installation and unpack the device. During this procedure, the dryer must always remain in an upright position. The components may be damaged when the unit is tilted or turned upside down.
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 name plate.
Installation Condensate drain Danger! Compressed air and condensate under pressure! The condensate is discharged at system pressure. The drain pipe needs to be secured. Never direct the condensate drain pipe at persons. The dryer is delivered with an already integrated electronically level-controlled BEKOMAT condensate drain. Connect the condensate drain with a collection system or container by properly screwing it on.
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 name plate of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature etc.). Prior to delivery, this dryer was thoroughly tested, packed and checked. Please verify the soundness of the dryer during the initial start-up and check the perfect functioning during the first operating hours.
Start-up Shut down and restart 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 Technical description 11.1 Control panel The control panel explained below is the only dryer user interface. Main switch ON-OFF switch Electronic control unit DMC18 Air and refrigerant-gas flow chart 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.
Technical description 11.5 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. 11.6 Condenser (air-cooled) The condenser is the component in which the gas coming from the compressor is cooled down, condensed and liquefied.
Technical description 11.12 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;...

Dryer is switched on and no service warning/alarm is active. Dryer is off or a service warning/alarm is active. 11.16.6 How to change operating parameters –...
Technical description 11.16.7 Selection of the BEKOMAT drain model The DMC18 controls two types of BEKOMAT drains. The correct settings are carried out in the factory and proper functioning is checked during the final inspection of the dryer. 11.17 Electronically level-controlled BEKOMAT condensate drain The electronically level-controlled BEKOMAT condensate drain boasts a special condensate management which ensures that condensate is discharged safely and without an unnecessary loss of compressed air.

Maintenance, troubleshooting, spare parts and dismantling Prior to carrying out maintenance works at the dryer, switch it off and wait for at least 30 minutes. Caution! Hot surfaces! During operation, several components can reach surface temperatures of more than 140°F (60°C). There is the risk of burns.

Maintenance, troubleshooting, spare parts and dismantling The dryer does not discharge the condensate – see the corresponding point. Extreme pressure drop The dew point is too low – the condensate is frozen and blocks the air – see the in the dryer.
Maintenance, troubleshooting, spare parts and dismantling 12.3 Recommended spare parts Spare parts list is printed on a dedicated sticker applied inside the dryer. On this sticker each spare part is identified with its ID Number and related Spare Part Number. Here below the cross-reference table between ID Numbers and exploded drawings Ref.
Maintenance, troubleshooting, spare parts and dismantling 12.4 Maintenance works at the refrigeration cycle Caution! Refrigerant! Maintenance and repair works at refrigeration systems must only be carried out by service technicians in accordance with the local provisions. The total amount of refrigerant in the system must be collected for recycling purposes, resource recovery or disposal.
