Cap.5 _ Handling and installation 5 - HANDLING AND INSTALLATION UNPACKING Standard series compressors are sent fully assembled, with the flex hoses separate. The compressor is packed in a cardboard box on a pallet to simplify handling and transport. The box containing the compressor must be moved according to the instructions shown on the box itself.
Cap.5 _ Handling and installation INSTALLATION WARNING Before proceeding with the installation tasks described below, read Chapter 3 “SAFETY REGULATIONS” carefully. 5.3.1 Positioning - Position the compressor in the designated area and check it is level. For compressor dimensions please consult section 4.3 “Technical characteristics”. - Check that the area in which the compressor is to min.
Cap.5 _ Handling and installation 5.3.3 Electrical connection The compressor is supplied with an electrical lead Model: MCH-8/EM and, depending on the model, with a plug (see Schuko plug supplied diagram at right). To connect up to the power supply just insert the plug in the mains power socket.
CHECKS TO BE RUN AT THE START OF EACH WORKING DAY Inspect the exterior of the compressor (couplings, pipes, pneumatic components etc.) and check for any oil leaks. Replace parts where necessary or contact AEROTECNICA COLTRI. 6.2.1 Lubricating oil level check Check that the lubricating oil level (a) is within acceptable limits (i.e.
If the compressor fails to shut down immediately after pressing the emergency pushbutton disconnect the compressor from the power supply and contact AEROTECNICA COLTRI. WARNING It is forbidden to alter pressure parameters without authorisation from AEROTECNICA COLTRI.
It is forbidden to refill them at a pressure greater than that indicated. IMPORTANT Should the safety valve fail to work properly contact the AEROTECNICA COLTRI assistance service. M M C C H H 8 8 - - 1 1 1 1 / / E E M M - - M M C C H H 1 1 3 3 - - 1 1 6 6 / / E E T T...

Cap.6 _ Using the compressor TANK REFILL IMPORTANT During refill the operator must be in the work area. It is advisable, during the bottle refill phase, to submerge the bottles in cold water so as to reduce the pressure drop. WARNING During bottle refill those not involved in the refill procedure must maintain a safety distance of at least 3 metres.
Page 42
Cap.6 _ Using the compressor To refill bottles proceed as follows: - Fit the hose connector (a) to the bottle valve (b). - Screw in the fixing knob (c) until it is completely tightened. - Check that the bleed tap (f) is closed by rotating it clockwise.
Cap.7 _ Maintenance 7 - MAINTENANCE WARNING Maintenance tasks must only be carried out by the AEROTECNICA COLTRI Customer Assistance Service or qualified personnel. DANGER All maintenance tasks must be carried out with the compressor off and the power lead unplugged from the mains socket.
Cap.7 _ Maintenance CHECKING AND CHANGING THE LUBRICATING OIL After putting the compressor into service the lubricating oil must be changed after the first 50 working hours.
