electrical components while voltage is applied
unless it is necessary for measurements, tests or
adjustments. Such work should be carried out only
by a qualified electrician equipped with the proper
tools and wearing appropriate body protection
against electrical hazards.
On a unit equipped with an Automatic Start/Stop
system, attach a sign stating 'THIS UNIT MAY
START WITHOUT WARNING' next to the display
panel.
On a unit equipped with an Automatic Restart
device, attach a warning notice stating 'THIS UNIT
HAS BEEN MODIFIED AND WILL START
AUTOMATICALLY ON APPLICATION OF POWER'
next to the display panel and on the inside of the
unit next to the starter contactors.
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
to make sure there is no one checking or working
on the unit before attempting to switch on remotely
controlled equipment. Attach a 'CHECK THAT ALL
PERSONNEL ARE CLEAR OF THE UNIT BEFORE
STARTING' or similar warning notice to the remote
start equipment.
Parts of the compressor, auxiliary equipment and
pipework with a working temperature in excess of
80°C must be insulated or guarded and clearly
marked in accordance with the local safety code.
If there is any indication that the compressor is
overheating it must be shut down and the cause
investigated. Beware of burns from hot metal parts,
hot oil and water when working on a unit which has
recently been shut down.
The compressor must not be operated at pressures
above the nominal pressure given on the data plate.
The compressor must not be operated in ambient
temperatures outside of those given under 'Leading
Particulars'.
The 'Noise at Work Regulations 1989' suggest that
ear protectors should be worn where noise levels are
85 dB(A) or higher.
Be aware that high noise levels can interfere with
communication.
6. MAINTENANCE AND REPAIR PRECAUTIONS
Maintenance, repairs or modifications must only be
carried out by competent personnel under a qualified
supervisor.
If replacement parts are needed use only CompAir
Genuine Parts.
Before removing any panels from the enclosure, if
fitted, or dismantling any part of the unit, carry out
the following preparatory operations:-
1. Isolate the compressor unit from the main
electrical power supply. Lock the isolator in the
'OFF' position and remove the fuses.
2. Attach a label to the isolator switch and
display panel carrying the warning 'WORK IN
PROGRESS - DO NOT APPLY VOLTAGE'. Do
not switch on electrical power or attempt to
start the unit if a warning label is attached.
3. Close the isolating valve between the
compressor unit and the users pipework. Close
the isolating valve in the cooling water inlet
pipe. Attach a label to each valve carrying the
warning 'WORK IN PROGRESS - DO NOT
OPEN'
4. Check that all pressurised air trapped in the
system is released to atmosphere. Check that
all pressure gauges on the display panel
register zero.
5. Ensure that the cooling water system has
been drained on water cooled models.
6. Check that the drain valve on the delivery
manifold is clear and air pressure released.
7. Open the manual drain cock to ensure that
pressurised air trapped between the first and
second stages has been released.
8. Stand clear of the valve covers when removing
the securing screws.
