Piping and Valve installation
General instructions for installation Pipes should be supported in such a way that the weight of the pipes is not taken by the screen In locating the supports, take care to ensure that the pipes do not cause stress to the screen The supports must allow for thermal expansion of the pipes If not, connections and screen body will be damaged! Piping Feed, accept, reject, reject dilution, rotor dilution, sealwater, deaeration, junk trap, emptying/flushing

Tension Principle
Power transmission in Andritz screens: V-belts Gearbox - only in large special units
NOTE! Do not tension the belts over the recommended area!
To prevent the screen from plugging one of the most important of the instruments is the pressure difference control alarm
Inspection before operation Check belt tensioning, the direction of the motor rotation, foundation, foundation bolts and “V-belt pulley taperlocks” Check that the interior is clean and that no foreign objects have entered the screen Inspect the pipe supports Remove the screen cylinder before starting the screen for the first time (not always necessary, normally according to Andritz start-up supervisor instructions)

Safety instructions
During Operation Check the maximum feed pressure of the screen from the dimensional drawing appended to the instructions Do not use the screen at a temperature higher than notified while the order was being made When the operating temperature exceeds 65C (prEN563), even short-term surface contact may cause skin burn All original guards of the screen must be appropriately fastened while the screen is running - do not remove them during operation! All maintenance of the screen and its drive motor is forbidden during operation, except: lubrication of bearings adjusting sealing water flow and pressure de-aeration of the screen
