1 INTRODUCTION
This manual provides information on the standard functions and procedures of all units in the series and is an
important supporting document for qualified personnel, but can never replace it.
All units are delivered with wiring diagrams, certified drawings, nameplate; and DOC (Declaration Of
Conformity); these documents show all technical data for the unit you have bought. In case of any discrepancies
between the contents of the manual and the documentation provided with the unit, always rely on the unit because it
is an integral part of this manual.
Read this manual carefully before installing and starting up the unit.
Improper installation could result in electric shock, short-circuits, leaks, fire or other damage to the equipment or injure
to people.
The unit must be installed by professional operators / technicians in compliance with the laws in force in the country
of installation.
The start up of the unit must also be performed by authorized and trained personnel and all activities must be carried
out in compliance, in full compliance with local laws and regulations.
INSTALLATION AND START UP ARE ABOSOLUTELY FORBIDDEN IF ALL INSTRUCTIONS CONTAINED IN
THIS MANUAL ARE NOT CLEAR.
If you are unsure about assistance and for more information, contact an authorized representative of the
manufacturer.
1.1 Precautions against residual risks
1. install the unit according to the instructions set out in this manual
2. regularly carry out all the maintenance operations foreseen in this manual
3. wear protective equipment (gloves, eye protection, hard hat, etc.) suited to the work in hand; do not wear clothes
or accessories that can get caught or sucked in by flows of air; tie back long hair before entering the unit
4. before opening the machine panelling make sure that it is firmly hinged to the machine
5. the fins on heat exchangers and the edges of metal components and panels can cause cuts
6. do not remove the guards from mobile components while the unit is operating
7. make sure that mobile component guards are fitted correctly before restarting the unit
8. fans, motors and belts drives might be running: before entering, always wait for these to stop and take appropriate
measures to prevent them from starting up
9. the surfaces of the machine and pipes can get very hot or cold and cause the risk of scalding
10. never exceed the maximum pressure limit (PS) of the water circuit of the unit.
11. before removing parts on the pressurised water circuits, close the section of the piping concerned and drain the
fluid gradually to stabilise the pressure at the atmospheric level
12. do not use your hands to check possible refrigerant leaks
13. disable the unit from the mains using the main switch before opening the control panel
14. check that the unit has been grounded correctly before starting it
15. install the machine in a suitable area; in particular, do not install it outdoors if it is intended for use indoors
16. do not use cables with inadequate sections nor extension cord connections, even for very short periods or
emergencies
17. for units with power correction capacitors, wait 5 minutes after removing the electric power supply before
accessing the inside of the switch board
18. if the unit is equipped with centrifugal compressors with integrated inverter, disconnect it from the mains and wait
a minimum of 20 minutes before accessing it to carry out maintenance: residual energy in the components, which
takes at least this length of time to dissipate, poses the risk of electrocution
19. the unit contains pressurised refrigerant gas: the pressurised equipment must not be touched except during
maintenance, which must be entrusted to qualified and authorised personnel
20. connect up the utilities to the unit following the indications set out in this manual and on the panelling of the unit
itself
21. In order to avoid an environmental risk, make sure that any leaking fluid is collected in suitable devices in
accordance with local regulations.
22. if a part needs to be dismantled, make sure it is correctly re-assembled before starting the unit
23. when the rules in force require the installation of fire-fighting systems near the machine, check that these are
suitable for extinguishing fires on electrical equipment and on the lubricating oil of the compressor and the
refrigerant, as specified on the safety data sheets of these fluids
24. when the unit is equipped with devices for venting overpressure (safety valves): when these valves are triggered,
the refrigerant gas is released at a high temperature and speed; prevent the release of gas from harming people
