1. GENERAL RECOMMENDATIONS
The purpose of this Manual is to provide users with instructions for installing, commissioning, using and
maintaining the units.
It does not contain the complete description of all the maintenance operations guaranteeing the unit’s long
life and reliability. Only the services of a qualied technician can guarantee the unit’s safe operation over a
long service life.
Please read the following safety precautions very carefully before installing the unit.
All refrigerant piping work, electrical work, air-tightness test, and brazing work must be performed by
qualied personnel.
1.1. SAFETY DIRECTIONS
This product contains R32 refrigerant that has a minimal environmental impact, thanks to its low value of
Global Warming Potential (GWP).
According to ISO 817, R32 refrigerant is classied as A2L, which is slightly ammable, since the ame
propagation rate is low, and non-toxic.
R32 refrigerant can burn slowly when all the following conditions are present:
² The concentration is between the lower and upper ammability limit (LFL & UFL).
² T Wind velocity < propagation of ame velocity
² Energy of the ignition source > Minimum ignition energy
1.2. INFORMATION ON THE REFRIGERANT USED
Follow the safety rules in forces when you are working on your appliance.
The installation, commissioning, use and maintenance of these units should be performed by qualied
personnel having a knowledge of standards and local regulations, as well as experience of this type of
equipment.
This appliance has not been designed for use by persons (including children) with reduced physical, sensorial
or mental faculties or by persons without any experience or knowledge of heating systems, unless they act
under the safety and supervision of a responsible person or have received prior training concerning the use
of the appliance.
The unit should be handled using lifting and handling equipment appropriate to the unit's size and weight.
Given the high refrigerant temperatures present at certain points in the cooling circuit, access to the area
protected by the panels is strictly reserved for qualied personnel only. These panels are easily opened with
a special tool. This tool should be kept by the installers or by the maintenance company.
Any wiring produced on site must comply with the corresponding national electrical regulations.
Make sure that the power supply and its frequency are adapted to the required electric current of operation,
taking into account specic conditions of the location and the current required for any other appliance
connected to the same circuit.
The unit must be EARTHED to avoid any risks caused by insulation defects.
It is forbidden to start any work on the electrical components if water or high humidity is present on the
installation site.
