INSTALLATION

2.1

SET-UP AND INSTALLATION

Once at the installation location, the adsorption dryers of the series HC-3 – HC-239,
which are supplied with a base frame, must be positioned so that all sides are easily
accessible. Should vibrations occur on the installation location, the adsorption dryer
is to be placed onto vibration dampeners.

Since the adsorption dryer has already been completely wired at our factory, the
customer only has to connect the power supply cable to the terminal strip according
to the supplied wiring diagrams.

Warning!

Use the appropriate, load-rated lifting equipment
and observe safe lifting procedures during all
operations of installation.

The equipment should be unloaded as close as
possible to the installation site to minimize any
chances of equipment damage.
