Filter Stocking Strategies
•
Although each Mineral Mizer arrives with a complete filter set, all practices will benefit by ordering an
annual service kit (DWS-RPKSD*) once installation is complete. This ensures the immediate availability
of each filter type until the practice’s unique filter replacement interval(s) emerge.
•
Mineral Mizers processing soft feed water (TDS < 150 ppm) may require only the DWS-RPKSD*
annually, depending on volume of DI water produced. In this case, all the filters should be changed.
•
Mineral Mizers supplied with hard feed water (TDS > 150 ppm) may require the DWS-RPKSD* annually
and 1 or more DWS-LRDC2s between annual service intervals. In this case, the practice may elect to
change only the pre-filter at the annual service interval and the DI filters when they are exhausted (TDS
> 5 ppm). If the weekly volume of DI water produced is consistent, a DI filter service interval unique to
the practice will emerge.
•
Feed water with high sediment content will cause clogging of the pre-filter. As the pre-filter clogs,
production of DI water diminishes only slightly until the end of the pre-filter’s productivity, making it
appear that the Mineral Mizer stops working abruptly. This practice should keep 1 or more pre-filters
in stock and may wish to change the pre-filter proactively once a clogging pattern emerges.
•
Be aware of changes to your DI water usage pattern / volume that may consume more DI water than
originally anticipated, resulting in more frequent changes of the DI filters. Some possibilities include
consumption by staff, taking water for home use or new boiled water applications.
Changing Filters
1.
Turn off the water supply by closing the Inline Valve on the Feed Water Tube.
2.
If this filter change is the result of a high TDS water reading (TDS ppm >5), discard the Tank water by
opening the Chrome Faucet over the sink until water flow stops. Release the valve.
3.
Close the Tank valve.
4.
Replace only one Filter at a time. Note the color dot for the Filter Sump upon which you are working.
Using the Sump Wrench, remove the Filter Sump and discard its filter and water. Remove the plastic
shrink wrap from the Filter and place it in the Filter Sump. Reinstall the Sump on the filter cap. Hand-
tighten the Filter Sump so it is snug. Repeat this step until all
filters for this service interval are replaced.
5.
Turn on the water supply by opening the Inline Valve on the
Feed Water Tube (inline to tube direction) and inspect the
Mineral Mizer and tank for leaks. Tighten the Filter Sumps
with the Sump Wrench if necessary.
6.
Open the Tank valve (inline to tubing direction).
7.
The Mineral Mizer is now producing water. To check the
mineral content, slide the Water Quality Monitor’s switch to
the
DI
position. Turn the monitor on by pushing its ON/OFF
switch. The display shows the water’s mineral content,
expressed in ppm TDS. This number will normally be in the
000 - 002 range. If the number is higher than 004, allow the
tank to fill until the display is consistently in the 000 – 002
range and then discard the water as before. This should take
no more than a few minutes.
Water Quality Monitor slide switch settings
FEED
- Displays the mineral content of the feed
(tap) water.
RO
– Displays the mineral content of RO water.
DI
– Displays the mineral content of the DI
water coming out of the red faucet or
dispensing gun, destined for your boiled water
applications.
