MIRAGE Line Compressors Instruction Manual

Major servicing
The check must carried out periodically, at a frequency that
depends on the dental surgery's workload.
For a dental surgery working eight hours/day fi ve days/week if
the compressor is monitored also by the dental surgery routine maintenance person, it is
suffi cient to arrange a service visit once every six or twelve months.
The major servicing: technician must use exclusively genuine original parts and must not
alter the compressors or their operation or tamper with the safety systems.
Do not weld the compressor air receiver.
Before starting work, read the Instruction Manual and any other relevant documentation
(exploded views, parts lists, wiring diagrams) in the reserved area of our website
www.4-tek.it.
Before carrying out maintenance work on the compressor, disconnect the electrical supply.
Make sure that the compressor reaches the maximum control pressure after each fi lling
cycle and check that the fi lling times are as shown in the table on page 5-03.
Check electrical power consumption in accordance with the values shown on the product
label.
When the compressor starts with diffi culty, check the mains voltage and the capacitance of
the capacitor (check the rating data).
A change in running noise or excessive vibration of the compressor can be a sign of a fault
and the risk of breakdown.
Check that the plant room temperature is no higher than 40°C: compressor operation may
be impaired in higher ambient temperatures.
Check to ensure there is no water in the receiver.
Check to ensure routine maintenance operations are performed correctly; if they are not,
inform the equipment owner of the importance of maintenance to keep the compressor in
good working order.
Change the air-intake fi lters at least once a year (Fig. 1).
