6. Resin Change
6.1 Capacity
Since the HydroPower
®
Ultra resin filter is used at different water filling points
with various degrees of hardness, the available quantity of completely
desalinated water differs.
The conductivity measurement is used to monitor water quality.
If a conductivity measurement indicates a value of >10 ppm, the resin is
depleted. The Ultra Resin Pack must be replaced.
Raw water quality can be determined in various ways:
a) Information from responsible water works (indication of overall hardness).
b) By measuring the mineral content with UNGER TDS-Meter

6.2 Resin Change - Ultra Resin Pack
REMOVE USED ULTRA RESIN PACKS
1. Close the water line.
2. Close the valve at bottom Water In of the filter (fig. A) and disconnect the hose.
3. Open the valve again, to let the water out of the system (fig. B).
4. Now remove the upper hose.
5. Press yellow FastLock Opening lever (fig. C) to get pressure out of the vessel.
6. Fix the base unit with your feet, press the top cap slightly down and use a
counter-clockwise 1/8 turn to release top cap assembly; remove and set aside
(fig. D).
7. Reach into housing and remove exhausted Ultra Resin Packs(s) by hand with the
rubber handle (fig. E); discard according to local regulations. Be sure that the valve at
the bottom is still open as this simplyfies the removal of the resin packs.

Install new Ultra Resin Packs by hand (fig. F) – be sure to seat bags with handle
facing up!
