SAFETY
PAGE 10
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. They must be suitably sized for the pressure and flowrate of the gas
involved. For specific details, contact Reavell.
Never remove or tamper with safety devices, guards or insulation material.
In order to limit the risk of Legionnaires Disease, Reavell advise caution with the use of cooling towers
for water cooling the compressor. Potable water should be used, treated where necessary to prevent
harmful bacteria from entering the compressed air. Cooling tower manufacturers should be contacted
for suitable maintenance schedules to prevent persons coming into contact with harmful bacteria.
Closed circuit or direct mains cooling is preferred.
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 ensure vertical lift and 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.
1.7.5 OPERATIONAL PRECAUTIONS
The compressor must only be operated by competent personnel under a qualified supervisor.
Ensure that all instructions concerning operation and maintenance are strictly followed and that the
complete installation with all accessories and safety devices are kept in good order.
Do not operate the compressor module, or any other parts of the equipment with any inspection cover
removed. e.g. compressor crankcase doors, valve covers,dispenser panel etc.
Never remove or tamper with safety devices, guards or insulation material.
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.
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
needed when essential work is carried out on the electrical system.
ALWAYS CONSULT A QUALIFIED ELECTRICIAN BEFORE ANY SUCH ESSENTIAL WORK.
If the compressor is equipped with a Remote Control device, attach warning notices stating
“THIS
UNIT CAN BE STARTED REMOTELY ” in prominent locations around the equipment.
As a further safeguard, take adequate precautions that no one is working or checking the unit before
attempting to switch on the remotely controlled equipment. Attach a
“CHECK THAT ALL PERSONNEL
ARE CLEAR OF UNIT BEFORE STARTING” or similar notice.
If there is any indication that the compressor is overheating it must be shut down. (
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 (if applicable) when working on a unit recently shut-down.
