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 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 name plate.
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 Shut down (see Section 11.1 "Control panel") • Ensure that the dew point temperature indicated on the electronic control unit is stable. • Interrupt the compressed-air supply. • After a few minutes, stop the dryer by switching off the main switch on the control panel (pos. 1). Restart (see Section 11.1 "Control panel") •...

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 11.10 Refrigerant pressure switches LPS – HPS – PV To ensure the operational reliability and the protection of the dryer, a series of pressure switches are installed in the gas cycle. LPS : Low-pressure guard on the suction side of the compressor, which is triggered when the pressure drops below the predetermined value.
