Key Plumbing System Component Overview (cont.)
Double Union Check Valve
This check valve is plumbed on the product
manifold and isolates the 5 micron reclaim
water from the fresh water bypass loop.
Reclaim water flows in the down direction.
Should the system go to fresh water bypass,
it “checks” the fresh water from flowing back
through the reclaim system thus going out
the “Treated” line to the wash equipment.
Fresh Water Bypass Solenoid Valve
The Fresh Water Bypass Solenoid on the
Reclaim System is a back-up water source
and will open should a major system fault
occur that stops the pump from running or
the system is placed in hand mode and a
wash activation signal is present. The valve
will vary in size depending on system model
but the purpose remains the same.
NOTE:
The valve may not close if the incoming
pressure exceeds 70psi.
Treated Water Line Components
The treated water line manifold is a unionized
assembly that is plumbed out to the wash
equipment. The line size should not be
reduced at the reclaim system connection.
If necesary, reduce the line at the point of
delivery. (ie at the pump or valve)
Pressure Transducer
The pressure transducer (as noted on page
40) works in conjunction with the PLC and
the VFD to deliver a steady 40psi to the wash
equipment. The VFD will “max out” at 60 Hz
in which case the pressure may not reach
40psi.
NOTE: the “Gen 3” transducer is a
0-10 volt DC device vs the older reclaims
using a 4-20mA device.

5 Micron Water
Pressure Gauge
This is a 0-100psi pressure gauge which
reflects treated water delivery pressure.
