Requirements for installation
For a correct installation of the the dryer following preconditions must be met on
the part of the owner.
Connections and lines for the infeed and outfeed of compressed air must be
provided.
A compressed air inlet valve as well as a compressed air outlet valve must be
installed by the owner, so that the dryer can be installed and maintained in a
depressurised condition.
A pressure retention valve must be installed downstream of the dryer when
the compressor is operated in cut-out mode (see Page 16). The pressure
retension valve is set to 80% of the operating pressure.
Steps must be taken to ensure that the dryer pressure does not drop below
the minimum input pressure:
—
HDK-MT, pressure level 100 bar: min. 50 bar
—
HDK-MT pressure level 350 bar: min. 100 bar
All pipes, couplings, and connections must have the correct diameter and
match the operating pressure.
A safety device must be provided in order to prevent the maximum
permissible operating pressure and the permissible temperature being
exceeded.
The data required to meet these preconditions are contained in the technical
documentation attached in the annex.
Warning!
If the above preconditions are not complied with, a safe operation of the
dryer cannot be assured. Also, the functionality of the dryer may be
detrimentally affected.
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.
► Check the bolt connections and retighten if necessary, as they could have
worked loose during transportation.
► Remove plugs on the pressure inlet and outlet.
All piping must be free from any stress and tension whatever!
Pipes subject to stress may burst due to the load placed on them during
operation. This may cause damage to property and personal injury.
► Use suitable pipes to connect the dryer to the compressed air system.
► The connection lines are to be installed at a slight incline in the direction of
the prefilter.
