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 of 15-20% 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 adequate production rate and extended membrane life.
Sediment Prefilter Replacement
Materials Required:
0.5 micron MicroTec™ Sediment Filter (SF-MT-0.5 -10),
Filter Wrench
Procedure:
1. Turn off water supply to the system.
2. Refer to Fig. A (System Diagram). Using the provided filter housing wrench,
remove the 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. Install the new prefilter onto the round port in the head of 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 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.
