Signs, instruction plates and danger zones at the dryer Hazard areas on the dryer Hazard caused by overpressure Hazard caused by electrical voltage Hazard caused by overpressure Hazard caused by sudden air ejection during expansion Symbol in operating Hazard area instructions Warning against hazardous electrical voltage Different parts of the dryer carry electrical current.
For your own safety Intended use of the dryer The dryer is exclusively intended for drying compressed air. Depending on defined input conditions, it dries compressed air for industrial use. The dryer is designed for compressed air, which is free from aggressive water, oil, and solid matter constituents.

Safety notes on specific operating phases Start-up Warning against sudden air ejection! During expansion the pressure is released suddenly through the muffler: A loud expansion noise is caused which may damage your hearing. Particles carried in the air can injure your eyes or skin. Always wear eye and ear protection, therefore, when you are in the vicinity of the dryer! Hazard due to a sudden release of pressure!
Page 13
For your own safety Maintenance of the dryer and fault removal Hazard due to a sudden release of pressure! Never remove any parts of the dryer, or manipulate the same in any way, for as long as the plant is still pressurised! A sudden escape of pressure may cause serious injuries.

Technical product description The stored humidity is then removed again from the drying agent and re- introduced into the ambient environment. To this end, the two vessels alternate between different operating modes. Whilst in one vessel, compressed air is de- humidified (adsorption), in the other vessel the humid drying agent is prepared for another charge (regeneration).
Available options Available options The following options are available for the dryer: Start-up device Auxiliary heater Bypass line Signalling contacts of control system Compressor synchronisation Dewpoint-sensing control Condensate drain pipe for preliminary and afterfilter ...

Technical product description Dewpoint-sensing control With a dewpoint-sensing control system, you can operate the dryer in fixed or variable cycles. In the fixed cycle, switchover is effected after a fixed time period (usually after 10 minutes). In the variable cycle, the switchover is effected in relation to the dew point reached and the charging of the drying agent.
Information on transportation packaging Transportation, installation and storage Danger due to incorrect transportation! The dryer must be transported by authorized and qualified specialist personnel only. During transportation all applicable national regulations for accident prevention must be complied with. Otherwise there is a risk of personal injury.
Transportation, installation and storage Transporting and installing the dryer Requirements for the installation site The conditions at the installation site have a large influence on the functional capability of the dryer and the service life of the drying agent. In order to ensure a mode of operation, which is as continuous as possible, and low maintenance, the installation site must meet the following requirements: The installation site must be located within a building - protected against...
Installing and anchoring Installing and anchoring Installing ► Remove the packaging of the dryer. ► Screw the enclosed ring bolts into the drilled holes on the upper valve block. ► Attach suitable lifting gear to the ring bolts. ► Place the dryer at its installation site. Transport by crane Anchoring the dryer The upright stand profiles of the dryer are provided with four pre-drilled...
Page 21
Transportation, installation and storage In order to store the dryer proceed as follows: ► Take dryer out of operation as described on page 35. ► Ensure that the compressed air inlet valve installed by the owner, and the installed compressed air outlet valve installed by the owner, are both closed, and that the dryer is depressurised.
Preconditions for installation Installation Only authorized and qualified specialist personnel may carry out work on pipes and electrical systems. As soon as the dryer has been set up at its installation location, you can install the compressed air infeed and outlet lines make the electrical connections. Preconditions for installation For a correct installation the following preconditions must be met on the part of the owner.
Installation Connect piping In order to ensure that the dryer operates optimally, the dryer must be assembled into the compressed air system free of all stresses. ► Ensure before connection that all infeed and outfeed compressed air lines and valves are clean and undamaged. ►...
Installing the electrical connection Installing the electrical connection Warning against electrical voltage Only qualified specialist personnel may carry out work on the electrical system! Installing the supply cable The components of the dryer have been connected to the control cabinet at the factory.

Installation Connecting the external signalling lines For compressor synchronisation The controller is fitted as standard with a digital input which makes the dryer regeneration dependent on operation of the compressor (switch S1 on the controller’s circuit board, see also figure below). If switch S1 is in the ON position, operation of the compressor and dryer regeneration run synchronously: When the compressor is stopped, the dryer regeneration also stops.
Requirements for initial start-up Start-up Note: You can order the initial commissioning and start-up from the manufacturer and have your personnel trained by the manufacturer. For telephone number, see page 6. Carry out all prescribed tests and checks. Before start-up, ensure that no tools or other foreign parts have been left ...
Start-up Setting times of the operating phases In its standard version the dryer is delivered with a time-dependent control system. The phase sequence occurs in a fixed cycle. With the optional dewpoint-sensing control, the dryer can also be operated at variable cycles (depending on the dewpoint).

Start-up Open compressed air supply and switch on dryer For start-up, please proceed in the sequence shown here. ► Ensure that the compressed air inlet and outlet valves installed by the owner are closed (see installation example on page 23). ►...
Changing cycle mode (optional) Operate dryer immediately in the compressed air system ► Ensure that the compressed air system downstream of the dryer is pressurised or that a start-up device (option, see page 16) was installed into the compressed air system directly downstream of the dryer. The importance of this increases with the size of the compressed air system downstream of the dryer.
Page 33
Start-up Which cycle modes can I choose? If the dryer is connected to a compressor synchronisation system and is equipped with the dewpoint-sensing control option, these two optional devices can only started together. The compressor synchronisation has thereby precedence over the dewpoint-sensing control. Compressor synchronisation (optional) If compressor synchronisation is enabled, the dryer can only be operated in conjunction with the compressor.
With dewpoint-sensing control (optional) Monitoring dryer operation The dryer operates fully automatically. However, you should carry out the regular checks described in the Chapter Maintenance and repair of the dryer. Warning against sudden air ejection! During expansion the pressure is released suddenly through the muffler: ...
Shutdown and restart dryer Shutdown and restart dryer In the following cases, the dryer must be fully shut down and depressurised: In the event of an emergency or malfunction For maintenance work For dismantling Risk of injury from escaping compressed air! Never remove any parts of the dryer, or manipulate the same in any way, as long as the unit is pressurised! Suddenly escaping compressed air might cause serious injuries.
If work is to be carried out on the electrical system If work is to be carried out on the electrical system ► Depressurise and shut down the dryer, following the instructions in the above chapter. Risk of injury due to voltage-carrying parts! The electrical supply cable and external power lines are live even after the dryer is switched off and, in the event of body contact, may cause serious injury! Before carrying out any work on the electrical system, the...
