Section 5 Figure 5-1. Front View Locating the Unit Installation Figure 5-2. Back View 1. Place the EASYpure II RF on a bench top convenient to your work area, noting the Clearance Requirements. If wall mounting is required contact Technical Services. 2. Using 1/2" I.D. tubing and tubing connectors (user supplied), connect the overflow drain tubing (lower left corner of the rear of the unit) to an atmospherically vented sink or floor drain.
Section 5 Installation Cartridge Installation Refer to Figure 5-3 for the procedure below. 1. Open cartridge access door in the rear of the unit by pushing the door latch down. 2. Remove a new Pretreatment cartridge from its plastic bag. 3. Wet the o-rings with water on both end caps. 4. Press the upper end cap into the pretreatment position until it bottoms out. 5. Lower the cartridge and insert the lower end cap \into the lower socket until it is firmly seated. 6.
Section 6 STOP Controls STANDBY START Figure 6-1. Control Panel Power Switch Control Panel Switches The power switch on the EASYpure II RF is located on the back right side of the unit directly above the power cord receptacle. The EASYpure II RF control panel incorporates three switches and a digital display.
Section 6 Controls Display In addition to displaying the temperature compensated (25°C) resistivity in megohms, the display also indicates operational modes and error indicators. The following is what can appear on the display: SbY Er1 rEC Er4 IdL Er5 Add Note On initial start-up, the purity meter may display “Er.1”. This is caused by air in the cell and should soon be replaced by a resistivity reading. If “Er.1” does not go out after the pump has run for a minute.
Section 6 Controls Standby (“SbY”) Idle Mode (“IdL”) Thermo Scientific In STANDBY (“SbY”) mode, the pump will restart for ten minutes out of every hour (i.e 50 minutes off, 10 minutes on). The display reads “rEC” which indicates recirculation. This will allow the unit to produce high quality water quickly upon being placed in Run Mode. It is recommended that the EASYpure II RF be placed in Standby Mode during non-work hours.
Section 7 Initial Operation Note Cartridge rinse up procedure must be followed after each cartridge and/or filter replacement. s Note In the event that the feedwater reservoir is overfilled, allow the excess water to drain from the reservoir through the overflow drain tubing before replacing the Ventgard cap. This will prevent wetting the filter element. s Warning Use a properly grounded electrical outlet of correct voltage and current handling capacity.
Section 7 Initial Operation Filling and Rinse Up (continued) 8. Place suitable container under draw-off valve. Open draw-off valve. 9. Press START and rinse one complete reservoir volume of water through the cartridges to drain. 10. Close draw-off valve. 11. Remove hose barb connection from draw-off valve. Keep hose barb for future use. 12. Remove the new 0.2 micron final filter assembly from its bag and insert it into the draw-off valve. Gently tighten, turning the filter to the right.
Section 8 Normal Operation Note When the unit is first put in the Run Mode, the display will show 10.0 for a few seconds. This is an arbitrary number that indicates the unit is running. Any number that appears after 10.0 indicates purity. s Operation 1. Remove the Ventgard cap. Do not allow water to enter the Ventgard cap. 2. Carefully pour pretreated feedwater into the feedwater reservoir until the water is level with the top of the sight gauge. Replace the Ventgard cap. 3.
Section 8 Normal Operation Feedwater Replenishment As water is drawn off from the EASYpure II RF, the feedwater reservoir will require refilling. This will be indicated by a low water level in the sight gauge or by the message “Add” on the display. To refill the reservoir: 1. Remove the Ventgard cap. Do not allow water to enter the Ventgard cap. 2. Carefully pour pretreated feedwater into the feedwater reservoir until the water is level with the top of the sight gauge. Replace the Ventgard cap. 3.
Section 9 Maintenance and Servicing Frequency of cleaning is difficult to determine because of variability in feedwater and usage. Cleaning is necessary when residual deposits are evident inside the feedwater reservoir or if a new 0.2 micron final filter clogs rapidly after installation even though the cartridges were properly rinsed before the 0.2 micron final filter was installed. To sanitize the EASYpure II RF, remove the 0.2 micron final filter and attach the hose barb that came installed on the unit.
Section 9 Maintenance and Servicing System Sanitation 1. Drain the system. a. Place the 0.2 micron final filter over a sink or place a bucket or other suitable large container under the filter and draw off water as described under Water Draw-Off in the Operation section of this manual. Draw off water until the water level in the feedwater reservoir is lowered to the point that the reservoir float switch disables the pump. Lift draw-off valve to closed position. b.
Section 9 Maintenance and Servicing System Sanitation (continued) 6. Drain the system as described in step 1 of this section. 7. Refill the reservoir with suitable feedwater and recirculate the water through the system for ten minutes. 8. Drain the system as described in Step 1 of this procedure. 9. Remove the empty cartridge tubes according to the instructions in the Cartridge Removal section. Drain and retain the empty cartridge tubes for future use. Remove the hose barb from the draw-off valve. 10.

Section 9 Maintenance and Servicing Cleaning Resistivity Cell (continued) 9. Carefully remove and discard the o-ring before cleaning the cell. 10. Wash the cell in a mild detergent solution followed by a 10% Hydrochloric or 10% Sulfuric acid solution (follow acid manufacturers warnings and recommended handling procedures found on package labels and Material Safety Data Sheets). This may be done in an ultrasonic cleaner or with a soft brush.
Section 9 Maintenance and Servicing Cartridge Replacement The frequency with which cartridges will need to be replaced is dependent on your feedwater characteristics, your purity requirements, and your daily usage. Replace the cartridges when the product water purity drops below acceptable levels of resistivity or when organic levels become too high. Remember, used cartridges can be recycled; see P.U.R.E. information packed with your new cartridges. Figure 9-2.
Section 9 Maintenance and Servicing Cartridge Removal (continued) 5. Wet the o-rings with water on both end caps. 6. Press upper end cap into pretreatment position until it bottoms out. 7. Lower the cartridge and insert the lower end cap into the lower socket until it is firmly seated. 8. Repeat Steps 3-7 with the EASYpure ULTRApure cartridge, placing it in position 2 and the EASYpure High Purity/Low TOC cartridge, placing it in position 3. Be sure to remove and replace one cartridge at a time. 9.
Section 9 Maintenance and Servicing Ventgard Cap Replacement Fuse Replacement The purifying media and filter in the Ventgard filter element have a limited capacity. Therefore, the Ventgard cap should be replaced every 120 days. The Ventgard cap is shipped as a complete unit; replacement involves simply removing the new Ventgard cap from its plastic storage bag and placing it on the reservoir.
