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

long service life.
Please read the following safety precautions very carefully before installing the unit.
1.1. SAFETY DIRECTIONS
Cutoff power supply before starting to work on the appliance.
When making the hydraulic connections, ensure that no impurities are introduced into the pipe work.
The fan-coil units may contain a small amount of oil incompatible with plastic polyethylene piping (PER/
HTA/PVC). The coil should be rinsed out before use to avoid any problem.
It is the installer’s responsibilityto contact their pipe supplierand take into account the general instructions
for the use of plastic pipes.
The manufacturer declines any responsibility and the warranty becomes void if these instructions are
not respected.
If you meet a problem, please call the Technical Department of your area.

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.
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,

2. INSPECTION AND STORAGE
At the time of receiving the equipment carefully cross check all the elements against the shipping documents
in order to ensure that all the crates and boxes have been received. Inspect all the units for any visible or
hidden damage.
In the event of shipping damage, write precise details of the damage on the shipper’s delivery note and
send immediately a registered letter to the shipper within 48 hours, clearly stating the damage caused.
Forward a copy of this letter to the manufacturer or his representative.
Never store or transport the unit upside down. Do not stand or transport the machines with casing on end.
For storing, each carton is marked with "up" arrows. It must be stored indoors, completely protected from
rain, snow etc. The unit must not be damaged by changes in the weather (high and low temperatures).
Excessively high temperatures (above 60 °C) can harm certain plastic materials and cause permanent
damage. Moreover, the performance of certain electrical or electronic components can be impaired.
The appliances are delivered fully assembled, factory tested and ready to operate.
