System Requirements &
Operation Guidelines
Plumbing
The membranes and high pressure pumps used on the SPECTRUM Systems require continuous flow of
water with a minimum feed pressure of 3.1 bar and must not exceed 38
°
C.
Feed Water Connection
1. Locate the 3/4" FNPT solenoid valve feed water inlet.
2. Attach the inlet piping to the 3/4" FNPT solenoid valve feed water inlet.
3. Be certain that all of the components of the feed water are soluble at the concentrations attained in
the system.
NOTE:
Feed line must be a minimum of 1/2".
Permeate (Product Water) Connection
Locate the threaded 1/2" MNPT fitting on the flow meter labelled “permeate” and attach to storage tank.
The permeate line can be run to the holding tank with PVC fitting or other FDA approved materials. This is
so the material being used does not dissolved into the permeate water.
NOTE:
The pH of the reverse osmosis permeate water will typically be 1 or 2 pH units lower
than the feed water pH. A low pH can be very aggressive to some plumbing materials such
as copper piping.
Concentration (Waste Water) Connection
Locate the 1/2" MNPT connector on the flow meter labelled “concentrate” and attach the line to a drain.
Run the concentrate line to an open drain in a free and unrestricted manner (no back pressure).
CAUTION
NOTE:
Any restrictions or blockage in the drain line can cause back pressure, which
will increase the system’s operating pressure. This can result in damage to the system’s
membranes and components.
