Remove a new 0.2 micron filter and bell assembly from its bag and insert it into Luer fitting. Gently turn it clockwise until it is fully seated in Luer fitting. 14. Remove protective cap from filter bell. 15. Flush 5-10 liters of water through filter to waste. 14

15 Normal Operation On initial start-up, purity meter may display ERR. This is caused by air in cell and should be replaced by a resistivity reading almost immediately. If ERR does not go out after pump has run for a minute or if it appears any time while EASYpure LF is in operation, refer to Troubleshooting section of this manual. 1. Press START button on front of EASYpure LF. The EASYpure LF s pump will begin to run and Purity meter will display resistivity of water in megohm-cm. 2. Allow water s resistivity to rise to desired purity before drawing off water. For low organic applications, draw off 50 to 100 ml of water from system and discard prior to drawing water for use. Water Draw off 1. Remove protective cap from filter bell. 2. Depress draw-off lever. 3. When draw off is complete, lift draw-off lever and replace protective cap on filter bell. Run and Standby Modes Since not all qualities of permissible feedwater will reach maximum resistivity after one pass through unit s cartridges (especially as cartridges near exhaustion), EASYpure LF has two operational modes. 15

16 NORMAL OPERATION In run mode, pump continuously recirculates water through cartridges. This is mode that unit enters upon start-up. If water will be drawn from EASYpure LF on a continuous basis throughout day, it is recommended that EASYpure LF be left in run mode. In run mode, purity meter display indicates resistivity of water available for draw off. In standby mode, pump runs for ten minutes out of every hour (i.e. ten minutes on, fifty minutes off). If water will be drawn from unit only infrequently, it is recommended that unit be put into standby mode. To put unit into standby mode, press STANDBY button on front of unit. The purity meter s digital display will display Sby to indicate that unit is in standby mode. 16
