5 Instructions for the use of pressure equipment according to PED directive 2014/68/EU
The SRHT 20-350 AC compressed-air refrigeration dryer contains pressure equipment in the sense of the 2014/68/EU
Pressure Equipment Directive. Therefore, the entire plant needs to be registered with the supervisory authority if required
in accordance with the local regulations.
For the examination prior to the start-up and for periodic inspections, the national regulations need to be observed, such
as the industrial safety regulation in the Federal Republic of Germany. In countries outside the EU, the respective
regulations in force there need to be adhered to.
The proper use of pressure devices is the basic requirement for safe operation. As regards pressure devices, the
following points need to be observed:
• The SRHT 20-350 AC compressed-air refrigeration dryer must only be employed within the pressure and
temperature range limits indicated by the manufacturer on the name plate.
• No welding must be carried out on the pressure parts.
• The SRHT 20-350 AC compressed-air refrigeration dryer must neither be installed in insufficiently ventilated rooms
nor near heat sources or inflammable substances.
• To avoid fractures resulting from material fatigue, the refrigeration dryer should not be exposed to vibrations
during operation.
• 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 SRHT 20-
350 AC compressed-air refrigeration dryer, the connected pressure generator (compressor etc.) must be set to the
max. permissible operating pressure. The integrated safeguard needs to be checked by an approved inspection
agency.
• The documents related to the SRHT 20-350 AC compressed-air refrigeration dryer (manual, operating instructions,
manufacturer's declaration etc.) must be kept safe for future reference.
• No objects whatsoever must be installed at or placed on the SRHT 20-350 AC compressed-air refrigeration dryer
and the connecting lines.
• Installation of the plant in frost-free places only.
• Operation of the plant is only permissible with fully closed and intact housing and cover panels. Operation of the
plant with damaged housing/cover panels is prohibited.
