6 Preparation

6.1 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

6.2 Preparing the installation site

Choose  an  installation  location  with  sufficient  space  to  transport  the  unit  in  and
out of the 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.

WARNING

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).

6.2.1 Installation site requirements of the outdoor unit

INFORMATION

Also read the following requirements:

General  installation  site  requirements.  See  the  "General  safety  precautions"
chapter.

Service space requirements. See the "Technical data" chapter.

Refrigerant  piping  requirements  (length,  height  difference).  See  further  in  this
"Preparation" chapter.

CAUTION

Appliance NOT accessible to the general public. Install it in a secured area, protected
from easy access.

This unit is suitable for installation in a commercial and light industrial environment.

NOTICE

The equipment described in this manual may cause electronic noise generated from
radio-frequency energy. The equipment complies to specifications that are designed
to  provide  reasonable  protection  against  such  interference.  However,  there  is  no
guarantee that interference will not occur in a particular installation.

It  is  therefore  recommended  to  install  the  equipment  and  electric  wires  in  such  a
way that they keep a proper distance from stereo equipment, personal computers,
etc.
