EXTRAORDINARY MAINTENANCE
TO BE CARRIED OUT BY A TRAINED AUTHORIZED TECHNICIAN, USING ORIGINAL SPARE PARTS
The frequency of checks is linked to the load of
work at the surgery. For surgeries working eight
hours a day, five days a week, a visit every twelve
months will suffice, provided the machines are also
monitored by staff trained for routine maintenance.
Technicians in charge of special maintenance
operations must use only original spare parts,
they must not alter the machines or their operation
and must not modify the safety devices. Most
importantly, they must not perform welds on the
compressor tank. Before intervening, refer to the
instruction manual, exploded drawings and wiring
diagrams. Before you get close to the compressor
remove power, if the main disconnection switch is
far from the compressor and cannot be visually
monitored, place a padlock on the switch.
Make sure that with each charge the compressor
reaches the maximum pressure value, the
charging time is approximately 45/55 seconds
while regeneration and cooling time is a third of the
charging time. Check electrical absorption. Every
time the compressor stops, a small amount of dry
air is counter flowed to dry the silica gel, if this is
not the case check or replace the solenoid valve
(13). When the compressor has difficulty reaching
steady state, check power voltage and condenser
capacity. Every six months check the absorptions
with clamp-on ammeter.
Check for leaks in the machine, in the pipework
and in the chairs. Check suction of each cylinder
(6 or 8 bar); the air drawn must not be less than
6000 N l/h. Replace any burned out bulbs in the
switchboard, replace any relays and contactors
that form sparks or that have worn out contacts. Do
not alter operation and electrical and mechanical
protections. Changes in operating noise may be
a sign of malfunction and danger of breaking; it
is therefore a good idea to replace noisy heads.
Check the temperature in the plant room, with a
temperature above 35 °C the air-drying system will
not operate correctly. Check that there is no water
in the tank or units. Check that routine maintenance
is performed correctly, otherwise we recommend
that you take responsibility for maintenance, with
the approval of the professional or of the owners.
Replacement of Hepa H14 filter. The Hepa H14 filter
is always delivered with an instruction sheet for
filter assembly and maintenance. In an environment
with clean air it is sufficient to clean the filters (A)
every 12 months. Before servicing the (L/S) filter
in addition to removing the current, it is necessary
to close the tap that connects the compressor
and drain out the air from the tank by opening the
tap (8). The Hepa H14 filter cannot be placed in an
autoclave. Spare cartridges are available; follow
the instructions (included in the filter).
If you need a more detailed description, we invite
you to refer to the operation manual of compressor
AC200 and AC300. You can find it on our website
