All compatible pressing units from Novopress (ACO203, ECO203, ECO202, ACO202, ACO202XL, EFP202 and AFP202) can be used with the compatible press jaws from Novopress up to 35 mm (metal pipe) and 32 (plastic pipe/ U-contour up to 50mm). The jaws are with their low weight and their compact design the perfect addition for the pressing units and are perfectly adapted to the pipe and fittings systems. Starting from dimension 42 mm (metal pipes) or 40 / 50 mm (plastic pipe, depending on system) Novopress has the press collars, which allow a perfect pressing result and small measurements. All collars for the compatible tools are driven with the adaptor jaws ZB203, ZB221 or ZB222 (second pressing 108 mm). The pressing profiles of the jaws and collars must be free from dirt and deposits. Clean with an agent such as methylated spirit. Follow the manufacturer’s operating instructions and service the pressing tools regularly. To avoid invalidating the warranty and ensure a reliable Pressfitting connection, the pressing tools have to be regularly checked and maintained. This is described in detail in the operating instructions for the tools under Safety, Maintenance and Repairs. The customer receives a service record to certify that this work has been carried out, and an annual service sticker with the next service date is affixed to the pressing tools.
