Preconditions for installation
22 HDK-MT350_EN_04
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.

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 (see also the installation example on page 23).

A pressure maintaining valve must be installed downstream of the dryer (see
also page 16). Adjust the pressure maintaining valve to 10–15 bar below
operating pressure.

Make sure the following minimum input pressures are permanently applied to
the dryer:
—
HDK-MT of pressure level 100 bar: at least 50 bar
—
HDK-MT of pressure level 250 bar and 350 bar: at least 100 bar

All pipes, couplings, and connections must have the correct diameter and
match the operating pressure.
Hazard caused by exceeding the limit values!
A safety device must be provided in order to protect against the maximum
permissible operating pressure from being exceeded.
The safety device must be installed so that the dryer is reliably protected
from exceeding the maximum permitted operating pressure even when
the temperature of the compressed gas increases.
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.
