Introduction Introduction The Barnstead EASYpure LF is a line-fed water purification system designed to provide Type I reagent-grade water with extremely low organic content. It uses a three-stage deionization process combined with a 0.2 micron filter to polish pretreated water (distilled, deionized, or reverse osmosis) to produce water with a resistivity of up to 18.3 megohms-cm and with a total organic carbon content of less than 15 ppb.
Specifications Specifications Dimensions and Clearance Requirements. EASYpure LF dimensions - 12 7/8" W X 19" D X 17 1/8" H (32.7 cm X 48.3 cm X 43.5 cm). Clearances: Sides - 4" (10.2 cm) minimum to allow air flow. Above - 12" (30.5 cm) minimum for removal of the top cover. Cartridge replacement requires that you be able to access the back of the unit and open the cartridge access door (total depth, unit + open door, = 34") (86.4 cm).
Declaration of Conformity Barnstead|Thermolyne hereby declares under its sole responsibility that this product conforms with the technical requirements of the following standards: EMC: EN 50081-1 Generic Emission Standard; EN 50082-1 Generic Immunity Standard; Safety: IEC 1010-1-92 Safety requirements for electrical equipment for measurement, control, and laboratory use; Part I: General Requirements per the provisions of the Electromagnetic Compatability Directive 89/336/EEC, as amended by 92/31/EEC and 93/
Unpackaging and Installation NOTE Cartridges and the 0.2 micron final filter are not provided with the EASYpure LF and must be ordered separately. WARNING Do not locate the EASYpure LF directly over equipment that requires electrical service. Routine maintenance of this unit may involve water spillage and subsequent electrical shock hazard if improperly located. Do not use in the presence of flammable or combustible materials; fire or explosion may result.
Tubing Adapter Installation Tubing Adapter Installation CAUTION 1. Completely disassemble the fitting. Refer to Figure 3 to familiarize yourself with the names of the component parts. 2. Make sure the tubing is cut off reasonably square and that no plastic burrs or ridges are present. 3. Place the grab ring and back-up ring in the hex nut in the order and orientation shown in Figure 3. Thread the nut onto the adapter. DO NOT use the o-ring at this time. 4.
Wall Mounting Wall Mounting Install the wall bracket on the wall in a location that is accessible to water and convenient to use. A minimum of 4 fasteners must be used. WARNING Do not locate the EASYpure LF directly over equipment that requires electrical service. Routine maintenance of this unit may involve water spillage and subsequent electrical shock hazard if improperly located. CAUTION Wall composition, condition and construction, as well as fastener type, must be considered when mounting this unit.
WALL MOUNTING 9. NOTE Ensure there are no kinks in the tubing that could restrict water flow. NOTE Outlet of feedwater storage tank must be above or at the same level as the inlet valve on the EASYpure LF. Install the four screws removed in step 7 through the bottom of the wall bracket and into the EASYpure LF. 10. Snake the tubing removed in step 4 through the hole in the EASYpure LF floor and the wall bracket and attach it to the quick disconnect body installed on the side of the bracket. 11.

Initial Operation NOTE If the EASYpure LF is wall mounted, rotate the EASYpure LF until the cartridge access door faces forward and the EASYpure LF locks into place. Initial Operation Cartridge Installation and Rinse Up NOTE The EASYpure LF’s cartridges must be installed in the proper order. NOTE The upper end cap is the one with the right-angle turn and the two flanges. The lower end cap extends straight out from the cartridge. NOTE 1.
Normal Operation Normal Operation 1. NOTE On initial startup, the purity meter may display “ERR.” This is caused by air in the cell and should be replaced by a resistivity reading almost immediately. If “ERR” does not go out after the pump has run for a minute or if it appears any time while the EASYpure LF is in operation, refer to the Troubleshooting section of this manual. NOTE For low organic applications, draw off 50 to 100 ml of water from system and discard prior to drawing water for use.
Installing Float or Pressure Switch Installing Float or Pressure Switch Accessories D0606 (float switch) and D2706 (pressure switch) are designed to protect the EASYpure LF pump by alerting the EASYpure LF of an inadequate feedwater condition so that the pump can be shut down. Use the following instructions for installation. 1. Disconnect electrical power. 2. If using D0606 float switch, follow the installation instructions included with the float switch for installation to tank. 3.
Maintenance and Servicing WARNING Disconnect from the power supply prior to maintenance and servicing. Refer servicing to qualified personnel. Do not disassemble water lines or remove cartridges where spilled water could contact equipment that requires electrical service. Disassembly of water lines and removal of cartridges will result in water spillage. Electrical shock hazard could result.
MAINTENANCE AND SERVICING NOTE Used cartridges may be recycled. See P.U.R.E. information packed with new cartridges. CAUTION Do not overtighten the 0.2 micron filter assembly onto the Luer fitting or use excessive force in seating it. The filter and/or Luer fitting can be damaged by overtightening or excessive force. NOTE If a newly installed 0.2 micron filter clogs rapidly after installation, the EASYpure LF may need to be sanitized to remove bacterial contaminants. See System Sanitization.
MAINTENANCE AND SERVICING WARNING 3. Depressurize system by opening the draw-off valve. 4. Open the cartridge access door in the rear of the unit by sliding the latch down and pulling the door toward you. The door will swing down. 5. Remove exhausted cartridge in the right-hand position by pulling it first up and then out. 6. Remove a D50245 sanitization cartridge from its packaging. Press the upper end cap of the D50245 sanitization cartridge into the upper right position until it bottoms out. 7.
MAINTENANCE AND SERVICING WARNING Replace fuses with those of the same type and rating. (See Parts Listing) 8. Replace fuse drawer. 9. Replace cover, power cord, and pump interlock plug. 10. Reconnect unit to power supply, and connect incoming water line at quick disconnect. Printed Circuit Board Replacement WARNING Depressurize system prior to opening cartridge access door. 1. Turn system off. 2. Disconnect incoming water line at quick disconnect. Depressurize system by opening outlet valve.

Replace the top cover. 16. Reconnect the power cord and the pump interlock plug to the unit, and reconnect the unit to the power supply.
Troubleshooting Troubleshooting Problem EASYpure LF completely inactive. (pump not operating, control panel not lit, etc.). Possible Causes No electrical power to EASYpure LF. Solutions Ensure that the EASYpure LF power cord is connected to a live power source and completely plugged into electrical outlet. Make sure power entry module switch is on. Fuses blown. Replace the fuses as indicated in the Fuse Replacement section. Pump runs, but no display (no digital display).
TROUBLESHOOTING Problem Possible Causes Solutions 0.2 micron final filter clogs rapidly after replacement. EASYpure LF contaminated with bacteria. Sanitize EASYpure LF according to the instructions in System Sanitization. Replace the 0.2 filter assembly as indicated in the 0.2 Micron Filter Replacement section. Short cartridge life. Cartridges being used are beyond expiration date Check the expiration date. Cartridges begin to lose capacity after being stored two years from the date of manufacture.
