EASYpure® II
1. Turn off the EASYpure II and disconnect it from the power supply.
Remove the power cord.
2. Disconnect incoming water line at quick disconnect. Depressurize the
system by opening the optional remote dispenser or unit draw-off
valve, allowing water to drain until no more water flows from the
valve(s).
Note Some water will drain from the ultrafilter when you disconnect it.
Have a container ready to hold the ultrafilter and catch the water while it
drains. Water could also drain from the tubing of the EASYpure II onto
your bench or floor. To avoid slipping and falling, clean up all spills.
3. Follow the instructions for ultrafilter installation found under
Ultrafilter Installation (Section 6), removing the old ultrafilter the same
way that is described in Push-to-Connect Fitting Tubing Removal
(Section 6).
4. Clean the EASYpure II. Refer to the Cleaning procedure at the
beginning of this section.
Replace the 0.2 micron final filter whenever any of the following
conditions occur: the product water flow rate is reduced, there is bacteria
break through, when cartridges are replaced, or when system is cleaned.
The 0.2 micron final filter is shipped assembled with a bell. To replace the
0.2 micron final filter assembly on draw-off valve or remote dispenser:
1. Remove the old 0.2 micron final filter assembly by turning it to the left
to unscrew it from the draw-off valve.
Note It is suggested that PTFE tape be applied to the threads of the 0.2
micron final filter to ensure a tight seal.
2. 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.
3. Rinse 5-10 liters of water through the filter to drain prior to using the
product water.
