Page 11: Exclusion From A Field Of Application
The maximum operating pressure indicated by the manufacturer on the name plate must not be exceeded. It is the installer's responsibility to install the appropriate safety and control devices. Prior to the start-up of the DRS30- DRS125 compressed-air refrigeration dryer, the connected pressure generator (compressor etc.) must be set to the max. -
Page 12: Storage
Allow a sufficient clearance on each side of the dryer for proper ventilation and to facilitate maintenance operations. The dryer does not require attachment to the floor surface. Do not obstruct the ventilation grille (not even partially). Prevent any recirculation of the outgoing cooling air. Protect the dryer against draughts. DRS30-DRS125... -
Page 13: Installation Plan
Note! Contaminated intake air! In the event that the intake air is strongly contaminated (ISO 8573.1 class 3.-3 or poorer quality), we recommend the additional installation of a prefilter (5 micron minimum), to avoid clogging of the heat exchanger. DRS30-DRS125... -

Page 16: Condensate Drain
During the installation and operation of this device, all national regulations regarding electronics and any other federal and state ordinances, as well as local provisions, need to be adhered to. The operator and the user must ensure that the dryer is not operated without panels. DRS30-DRS125... -
Page 17: Initial Start-Up
(flow-rate, temperature of the incoming air, ambient temperature, etc.) During the operation, the refrigerating compressor runs continuously. The dryer needs to be switched on during the entire compressed-air usage time, even if the compressed-air compressor works periodically. DRS30-DRS125... -
Page 18: Shut Down And Restart
The dryer must not be started up more than six times an hour. Wait at least five minutes prior to every restart. The user is responsible for the compliance with these provisions. Irreparable damage can be caused when starting up the device too often. DRS30-DRS125... -

Page 20: Technical Description
The low-pressure gas is resupplied to the compressor, where it is compressed again. It then re-enters the cycle. In phases of a reduced compressed-air load, the excess refrigerant is resupplied automatically to the compressor via the hot gas bypass valve. DRS30-DRS125... -
