3. GENERAL SAFETY PRECAUTIONS
(Cont.)
• Before releasing compressed air through a hose
make sure the free end is held securely so that it
cannot whip and cause injury.
• Avoid injury by using a hoist to lift heavy loads.
Check that all chains, hooks, shackles and slings
are in good condition and are of the correct
capacity. They must be tested and approved
according to local safety regulations.
• Cables, chains or ropes should never be applied
to lifting eyes. Always use an appropriate shackle
or hook, properly positioned. Arrange lifting
cables so that there are no sharp bends. Use a
spreader bar to avoid side loads on hooks, eyes
and shackles and never leave a heavy load
unattended.
• When a load is on a hoist stay clear of the danger
area beneath and around it. Keep lifting
acceleration and speed within safe limits.
4. INSTALLATION PRECAUTIONS
• Installation work must only be carried out by
competent personnel under a qualified
supervisor.
• A fused isolator switch must be fitted between the
main power supply and the compressor.
• Precautions must be taken to ensure that no
injury is caused to passers-by through loose
clothing being sucked into compressor intake.
• Ensure that the discharge pipe from the
compressor to the users pipework, receiver or
storage is free to expand and that no flammable
material is within the vicinity. If any such material
is close-by take steps to preclude ignition.
• A manual shut-off valve should be fitted in the
discharge line to allow the compressor to be
isolated. Non return valves cannot be relied upon
for isolating parts from a pressure system. A
safety valve must be installed between any
compressor unit and the isolating valve.
• A pressure reliving device must be fitted to every
pressure vessel, or equipment containing air or
gas above atmospheric pressure. Never remove
or tamper with safety devices, guards or
insulation fitted. In order to limit the risk of
Legionnaires Disease, CompAir UK LTD advise
caution with the use of cooling towers for water
cooling the compressor. Closed circuit or direct
mains cooling is preferred.

• Pipework or other parts with a surface
temperature above 70°C which may be
accidentally touched in normal operation must be
guarded or insulated. Other high temperature
pipework should be clearly marked and all
pipework should be clearly marked.
5. OPERATIONAL PRECAUTIONS
• The compressor must only be operated by
competent personnel under a qualified
supervisor.
• Do not operate compressor with any removable
inspection cover removed e.g. crankcase doors,
valve covers etc.
• Never remove or tamper with safety devices,
guards or insulation materials.
• The compressor must only be operated at the
supply voltage and frequency for which it is
designed. Always isolate power before
maintenance or servicing.
• When mains power is ON, lethal voltages are
present in the electrical circuits and extreme
caution is need when essential work is carried out
on the electrical system. ALWAYS CONSULT A
QUALIFIED ELECTRICIAN BEFORE ANY
SUCH ESSENTIAL WORK.
• 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 appropriate 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.
