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 adequate production rate and
extended membrane life.
Sediment Prefilter Replacement
Materials Required:
Sediment prefilter (SF-MT-0.5-10),
Filter Wrench (WR-UNIV)
Procedure:
1. Turn off water supply to the system.
2. Using the provided filter housing wrench, remove the first housing on
the left. Unscrew it clockwise as viewed from the top.
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-tight-
ening will damage housings and void your warranty.
6. Proceed with carbon block filter replacement.
