Trane CGA Series, Installation Operation & Maintenance

Page: 23 / 24

Maintenance
Maintenance operations are fundamental in order to keep the units running properly, both purely functional and
energetically points of view. Every Trane unit comes with a logbook, in which the user or the person delegated to
machine maintenance can keep all the required notes, in order to keep a historical log of the Trane unit. A lack of notes
in the logbook could be considered proof of careless maintenance.
Sight check of the under pressure vessels state
The risks due to the pressure inside the circuit have benne eliminated or (when it is not possible) reduced by means of
safety devices. It is important to check periodically the status of these devices and to carry out the components
inspections and replacement as follows.
Check at least once per year the under pressure vessels state.
It is important to check that the surface does not get rusty and that neither corrosion nor deformations are visible.
In case the superficial oxidisation and the corrosion are not properly controlled and stopped in time, cause a thickness
reduction with a consequent reduction of the vessel mechanical resistance.
Use antioxidant paint or products to protect.
