15. Turn the ON/OFF switch to the ON position. The high-pressure pump will
operate and the machine will begin to build pressure. As you are
operating, make sure to watch the pressure gauge on the instrument
panel. The machine is designed to operate at 115 psi (15.2 bar).
NOTE:
Do not allow the pressure to exceed 140 psi. If the pressure exceeds 140 psi,
open the concentrate flow control valve until the pressure gauge shows 140 psi
or less.
As the machine purges the air and fills with water, the pressure will
gradually increase. You should see water flowing from the permeate and
concentrate flow meters. If you do not see flow from these points, turn the
machine off and return to Step 1.
CAUTION:
Never allow the machine to operate without adequate water pressure. This can
cause severely damage to the high-pressure pump.
16. Gradually close the concentrate flow valve. As you close the valve, watch
the pressure gauge and your concentrate flow meter. Close the valve until
your concentrate flow meter displays your design flow, and you do not
exceed 140 psi. If you reach 140 psi before the valve is completely
closed, open the recycle flow control valve one full turn, then continue to
close the concentrate flow control valve. Continue to close the
concentrate flow control valve until it is completely closed and your
pressure is below 140 psi.
The concentrate flow control valve has a drilled orifice to ensure a pre-
determined amount of flow and pressure in the closed position. This
orifice is sized to operate the machine at 75% recovery.
17. With the concentrate flow control valve fully closed and the pressure
below 140 psi, gradually close the recycle flow control valve until the
pressure reaches 140 psi.
Your machine is now operating at the design pressure and flow rates, in a
75% recovery configuration. Your specific needs or conditions may
dictate the need to operate the machine at a lower recovery. If you wish
to operate in a recovery configuration lower than 75%, Step 18 will explain
the necessary steps.
