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).
