Periodic checks
The ACX2281 service station must be checked over
regularly as set by local legislation.
The following checks should be performed to ensure safe and
reliable operation:
—
Make sure no corrosion or leakage is present in the
internal cylinder and other metallic parts of the equipment
(under normal conditions the internal cylinder life is at
least 20 years).
—
If automatic safety valve trips, contact technical support
to have unit inspected, resolve any issues and replace
valve if necessary.
—
If the safety pressure switch trips, check the connection
of the cables and correct connection to the PCB. Contact
technical support for additional assistance.
—
Check that external charging hoses - both red (HP) and
blue (LP) - are in good order and undamaged. In the case
of damaged hoses, discontinue use of ACX2281 until
replacement hoses are procured.
—
Verify that vacuum pump oil and filter dryer have been
replaced according to schedule for proper functioning
equipment.
