1  INTRODUCTION
Prior to the initial start-up of the AR05 units, the people
involved should be thoroughly familiar with these instructions
and the specifi c project data for the installation site.
The AR05 heat pumps are designed to provide a very high
level of safety and reliability making installation, start-up,
operation and maintenance easier and more secure. They will
provide safe and reliable service when operated within their
application range.
The procedures in this manual are arranged in the sequence
required for machine installation, start-up, operation and
maintenance.
Be sure you understand and follow the procedures and safety
precautions contained in the instructions supplied with the
machine, as well as those listed in this guide, such as:
protective clothing such as gloves, safety glasses, safety
shoes and appropriate tools, and suitable qualifi cations
(electrical, air conditioning, local legislation).
To fi nd out, if these products comply with European direc-
tives (machine safety, low voltage, electromagnetic compati-
bility, equipment under pressure, etc.) check the declarations of
conformity for these products.
