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.

indicator -1- and any fault code or if the HVAC unit
does not start, contact a Johnson Controls Inc.

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

or maintenance of the unit that is in any way inconsistent with that described in this document or others
specifically provided with the platform.
