nel.

Before carrying out any work on the unit or accessing internal parts, make sure you have turned off the 

power supply to it.

The compressors and delivery pipes are very hot. Be particularly careful when working near them.

Be particularly careful when working near the finned coils as the aluminium fins are very sharp.

Do not access moving parts without guards.

In units with capacitors and/or inverters, certain components can remain live for several minutes even after 

having turned off the main switch.

Wait 10 minutes before working on the electrical parts of the unit.

Circuits supplied from external sources (made with orange cable) can remain live even after the power sup

-

ply to the unit has been turned off.

Work on the unit only if there is sufficient lighting for the type of work to be carried out.

8.1 Adjustments

All the parameters that control the operation of the unit can be set through the user interface of the control.

Refer to the control manual should modifications be necessary, but contact the manufacturer first.
Any calibration affecting the unit safety must not be changed.
If in any case replacement becomes necessary, it is essential to use components supplied by the manufacturer (in the case 

of adjustable parts) or with the same sizes and characteristics (in the case of fuses).
