8.2 INSTALLATION PRECAUTIONS
Installation work must only be carried out by competent personnel under
a “PERMIT TO WORK”
system
A fused isolator switch must be fitted between the main power supply and the compressor. The isolator
shall be suitably sized and be in accordance with Section 7.2 of EN 60204-1:2006 & A1:2009.
If not requested with the supplied equipment, suitably sized over-current protection must be provided to
protect the power circuit. The protection shall be in accordance with Section 7.2 of EN 60204-1:2006 &
A1:2009.
Guards must be fitted to make sure that Foreign Objects cannot be drawn into cooling air intake
ducting or louvers.
Ensure that the discharge gas piping from the compressor module to the users pipework, gas storage
cylinders or gas dispensing system 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. They must be suitably sized for the pressure and flowrate of the gas
involved. For specific details, contact Gardner Denver.
To minimse the risk of Legionnaires Disease, Gardner Denver advise caution with the use of cooling
towers for water cooling the compressor. Potable water should be used, and treated where necessary
to prevent harmful bacteria from entering the compressed air. The cooling tower manufacturers
maintenance schedules should be observed to prevent the development of harmful bacteria. Closed
circuit or direct mains cooling is preferred.
Always use an appropriate shackles or hooks, 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.
