090 - MAINTENANCE
Constant supervision of machine conditions and correct maintenance guarantee reliability and
efficient operation of the entire system over time. This chapter caters for qualified personnel and
addresses scheduled controls and maintenance but also deals with a series of checks that the user
himself can do at the indicated intervals. For example, some simple visual controls of the system’s
main components that require no particular technical skills
Periodic machine maintenance
•
Control of machine structural integrity: the metal panels composing the casing must be firmly
secured to the structure; removable panels and peep panels must not cause irregular vibration or
noise during operation.
•
Control oxidized parts: Rust must be removed; ascertain rust causes, remedy and if necessary
repair.
•
Control of leaks: unusual oil spots on the floor, condensation due to damaged insulation and
leaking piping demand immediate assistance from Epta after-sales service.
•
check the integrity of the electric power line: the power cord connecting the machine to the
power source must be in perfect condition, with no cracks or damage that may jeopardize
insulation. Should repairs be needed, request assistance from the after-sales service.
•
Check the tripping capacity of safety pressure-switches as per the laws in force
•
Check the tripping capacity of the pressure-switches protecting the compressor
