SEDIMENT PREFILTER REPLACEMENT:
A Sediment Filter will usually last approx. 4-6 months, depending on the quality of
the tap water and quantity of water being produced. (The life span of the filter is
determined by the turbidity, iron content, organics, and total particulate volume
in your water source). The best way to determine when your Sediment Prefilter
needs replacement is to monitor the Pressure Gauge. When you have a drop in
pressure of15-20% below your normal gauge pressure, replace the filter. To verify
this, run water through the system without the filter in its housing. If the pressure
returns to your normal house pressure without the filter, you will know the filter
you just took out was plugged up and causing the pressure drop.
**NOTE: A drop in the system’s production is, in most cases, an indication that
the sediment filter has become saturated with contaminants and will need to be
replaced. If you remove the sediment and the pressure does not return to normal,
the carbon filter may be plugged. If your water contains a great deal of sediment
or chlorine, the prefilters may require more frequent changes to maintain ade-
quate production rate and extended membrane life.
Sediment Prefilter Replacement Procedure
Materials Required:
0.5 micron MicroTec™ Sediment Filter (SF-MT-0.5 -10),
Filter Wrench
1.
Turn off water supply to the system.
2.
Refer to Fig. A (System Picture). Using the provided filter housing wrench,
remove the first housing on the left. Unscrew it counterclockwise as viewed
from the bottom.
3.
Remove the old filter and discard.
4.
Thoroughly wash the housing with a mixture of hot soapy water and a few
teaspoons of household bleach. Rinse well with clean hot water.
5.
Insert the new prefilter into the housing. Screw the housing back onto the
assembly and hand-tighten
only
.
NOTE: Do not use filter wrench to tighten housings. Over-tightening
will damage housings and void your warranty.
6.
Proceed with carbon block filter replacement, if needed.
NOTE: If your water contains a great deal of sediment or chlorine,
the prefilters may require more frequent changes to maintain
adequate production rate and extended membrane life.
