Overview: Preparation

This chapter describes what you have to do and know before going
on-site.

It contains information about:

▪ Preparing the installation site

▪ Preparing the refrigerant piping

▪ Preparing the electrical wiring

5.2

Preparing the installation site

Do NOT install the unit in places often used as work place. In case
of  construction  works  (e.g.  grinding  works)  where  a  lot  of  dust  is
created, the unit MUST be covered.

Choose an installation location with sufficient space for carrying the
unit in and out of the site.

The  appliance  shall  be  stored  in  a  room  without
continuously  operating  ignition  sources  (example:  open
flames, an operating gas appliance or an operating electric
heater).
