Rotating direction of the Scroll compressors
The scroll compressors and the fans only operate correctly if they rotate in the correct direction. All of
the motors and compressors in the unit are connected so that they rotate correctly.
If the compressors are not connected correctly and are rotating in the wrong direction:
• The compressor will not compress.
• Operating noise will be abnormal.
• Electricity consumption (A) will be low.
• They overheat.

• All side panels except for that of the electrical box, must be fitted, closed and secured with their
corresponding locks before turning the general switch on the unit.
• The unit has a remote control, which means that the fan turbine may start unexpectedly.
To unlock the unit, see "Restarting the HVAC unit in case of fault" in the User Manual.
Where the thermostat screen continues to display the
indicator -1- and any fault code or if the HVAC unit
does not start, contact a Johnson Controls Inc.
Authorised Technical Assistance Service.
1.15 Regular maintenance tasks performed by specialised
personnel
Like any other machine, the unit requires regular maintenance, as the wear to which some of its parts
are subjected can affect its mechanical reliability, electrical consumption and working life.
In order to keep the unit in similar working order to when it was installed and commissioned, a series of
maintenance tasks must be performed every so often.
Furthermore, all maintenance and servicing tasks required by local and national regulations must be
carried out.
D A N G E R
Only a Johnson Controls Inc. Authorised Technical Assistance Service with the appropriate technical
resources and suitably trained personnel may perform the unit maintenance tasks.
C A U T I O N
Johnson Controls Inc. shall not be considered responsible for any damage caused by inappropriate use
or maintenance of the unit that is in any way inconsistent with that described in this document or others
specifically provided with the platform.
