Page 13: Installing And Fixing The Analytical Sieves
Installing and fixing the analytical sieves The AS200 is suitable for use with analytical sieves with outside diameters of up to 215 mm. It is possible to install up to 16 analytical sieves 25 mm high or 8 sieves 50 mm high, plus the base pan in each case. - Page 14 I are to be pressed simultaneously, briefly, to release tension. We recommend using talcum powder if the base pan sticks to the smooth surface of the sieve carrier when removing the sieve stack. 21.11.2001 Retsch GmbH Doc. No E98.014-016.9999 A...

Base pan with water drain, matching the sieve diameter. Preparations Position your AS200 near a water drain. Use a hose to connect the spray nozzle in the clamping cover to a water faucet. Connect the drain from the base pan with the drain or a suitable container to receive the liquid. - Page 32 Never place the AS200 directly in a basin for operation. Fatal electrical shock hazard. During wet sieving always connect the AS200 to a socket which is protected by a ground fault interrupter. Adjust the volume of water applied so that it will just wet the surface of the screen.
