•
Do not open starter compartment to touch electrical components while voltage is applied unless it is
necessary for measurement, test or adjustment. Such work should always be carried out by a qualified.
Electrician with appropriates tools and protection against an electrical hazard.
•
If the unit is equipped with a Remote Control device, attach warning notices stating "THIS UNIT CAN BE
STARTED REMOTELY" in prominent locations, one on the outside of the unit, the other inside the
control compartment.
•
As a further safeguard, take adequate precautions that no one is working or checking the unit before
attempting to switch on remotely controlled equipment. Attach a "CHECK THAT ALL PERSONNEL ARE
CLEAR OF UNIT BEFORE STARTING" or similar notice.
•
Compressed air and gas piping, together with cooling water piping and other parts, with surface
temperature greater than 70°C and may be accidentally touched, should be guarded or insulated.
•
If there is any indication that the compressor is overheating it must be shutdown. (A high air or gas
temperature switch is fitted as standard to guard against operating with excessive temperature). Beware
of burns from hot oil and water when working on a unit recently shutdown.
•
Do not operate the unit when guards provided for protection for all rotating and reciprocating parts have
been removed for essential maintenance. Secure guards following any servicing or repair.
•
Local noise regulations must be observed. Ear defenders are suggested by Noise at Work Regulations
1989 when the level is greater than 85 dB A at one meter. Be aware high noise levels can interfere with
communication.
1.4.6 MAINTENANCE & REPAIR PRECAUTIONS
•
Competent persons under qualified supervisor must carry out maintenance repair and modifications.
•
The compressor will have a preserving oil applied to interior surfaces (Oil lubricated models). Oil free
models will have desiccant bags in valve covers and distance pieces.
•
Handling components such as seals, gaskets and diaphragms should not present a personnel hazard.
Preservation oils again should not present a personnel hazard if handled under normal handling
practices.
•
Whilst compressors are asbestos free, treat all damaged gaskets as asbestos - when the Asbestos at
work regulations apply.
•
Viton 'O' seals under normal operating conditions are safe.
•
However, should there be a fire within the compressor or these seals are likely to exceed a temperature
of 300°C the material will decompose.
•
Degraded Viton gives off Hydrogen Fluoride fumes and if in contact with the skin an acid formed
causes severe burns.
•
If Viton seals appear charred or gummy do not touch with unprotected hands: use neoprene or PVC
gloves.
•
Wash the area with limewater and avoid breathing any fumes. If contamination of the skin occurs washes
with limewater and seeks medical advice.
Pre-Maintenance Operation
•
Isolate the compressor from the main electrical supply. Lock the isolator in the OFF position and remove
fuses.
•
Attach a label " WORK IN PROGRESS - DO NOT APPLY VOLTAGE" .
•
Close the isolating valve between the compression unit and user's pipework. Close the isolating valve in
the cooling water inlet pipe. Attach a label "WORK IN PROGRESS - DO NOT OPEN".
•
Check that all pressurised gas trapped in the system is released to atmosphere or safely to gas storage.
Check that all pressure gauges register zero.
•
Ensure that the cooling water system has been drained.
•
Check that the drain valve on the delivery manifold is clear and gas pressure has been released.
•
Check that all interstage drains are open to ensure any gas trapped between stages has been released.
