Operation – Pull off the ventilation tube for the venting of the material drum on the follower plate. – Open the shut-off valve for the venting of the material drum on the follower plate. Set the control lever of the ram back to As soon as material is visible at the connection for the venting of the material drum, the air has escaped from the material drum.
Operation 5.1.4 Filling and ventilating the proportioning and mixing unit 1. Place a material collecting vessel under the material outlet of the mixing unit (without static mixer). 2. Press the “Start” button on the operating panel. The proportioning cylinders of both components are now pressed out and filled again using the feed pumps.
Operation 5.4 Flushing Flushing the machine is necessary during initial commissioning so that the processing material is not influenced by the test substance with which the machine was tested for fault-free functioning in the factory, when material is changed, when work is interrupted and when decommissioning, in order to flush the processing material out of the machine before it hardens.
Operation 5.6 Decommissioning 1. Close the compressed air shut-off valves at the compressed air connection underneath the operating panel and at the feed pumps, optionally on the pressure vessel. 2. Disassemble the static mixer. The static mixer is only suitable for one-time use and must be properly dis- posed after the end of use.
