A pressure - operated Automatic Shutoff (ASO) Valve and a Float Valve are
provided for convenient filling of a storage reservoir.
NOTE: SpectraPure does not recommend using the Float Valve for topoff
due to evaporation. The short duration of the fill cycle when using
a float valve will rapidly deplete the life of the DI cartridges due
to TDS creep. Instead, we recommend the use of high/low float
switches in the reservoir/sump to extend the fill cycle and minimize
the effects of TDS creep. (see SpectraPure part number LLC-SVC-
2FLT-2-10)
The Manual Flush Valve may be used to periodically rinse the accumulated
impurities and concentrated waste water from the surface of the RO
membrane to help increase the life of the membrane. The Manual Flush
Valve is located in parallel with the flow restrictor (see page 9) and, when
opened, provides a high-flow bypass of waste water used to purge
concentrated brine from the membrane housing and rapidly flush any
particulates from the membrane surface. This is especially useful in hard
water conditions. We recommend that the valve be turned ON for 30
seconds at the start of a fill cycle and at the end of a fill cycle. BE SURE to
turn the Flush Valve OFF before making product water.
