12.5 Coolers
General
Keep the coolers clean to maintain their efficiency.
Never use a high pressure water jet to clean the compressor.
Instructions for air-cooled compressors
• Stop the compressor, close the air outlet valve and switch off the voltage.
• Cover all parts under the coolers.
• Remove any dirt from the coolers with a fibre brush. Never use a wire brush or metal objects.
• Next, clean with an air jet in the reverse direction to normal flow. Use low pressure air. If necessary,
the pressure may be increased up to 6 bar(e) (87 psig).
• If it is necessary to wash the coolers with a cleaning agent, consult Atlas Copco.
