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

maintenance of the HVAC unit, which includes anything inconsistent with that described in this document
