USING THE PRESSURE GAUGE:
The pressure gauge is used to monitor the condition of the Sediment
and Carbon Prefilters. With the Sediment and Carbon filters removed, the
gauge will indicate the “actual” tap water input pressure. When the prefilters
are “new”, the pressure shown on the gauge will be slightly less than the
actual tap water pressure and as the filters age, the pressure will drop due
to the sediment that will collect in the prefilters. When the pressure on the
gauge drops below 40 PSI or as the filters collect particulates and the
pressure drop is greater than 15% to 20% of the normal water pressure,
the prefilters are in need of replacement.
NOTE: When the pressure on the pressure gauge drops below the normal
readings; do not assume that the sediment filter is the only cause.
In some geographical areas where the input water contains a high
percentage of very small micron particulates, the carbon filter may
become clogged before the sediment filter. (The filters may look
“new” but still cause the water pressure to drop). Do not judge the
condition of the prefilters by their color, always use the pressure
gauge to determine the condition of the prefilters.
USING THE MANUAL FLUSH VALVE
The Manual Flush Valve can be an important factor in extending the life
of your RO membrane. It helps to flush the accumulated salts from the
membrane surface and also lowers the TDS in the membrane housing. We
recommend that you flush the system for 30 seconds upon startup and
again when shutting the system down.
When the handle is perpendicular to the tubing, the waste water is forced
to pass through the flow restrictor which builds backpressure in the
membrane housing and reverses the osmotic flow to produce pure water.
When the handle is parallel to the tubing, the water flows unimpeded
through the waste water line, resulting in a fast flow across the surface of
the membrane and down the drain line.
