E4H Series
Operation & Maintenance Manual

17

sure to watch the pressure gauge on the instrument panel. The machine is
designed to operate at 220 psi (15.2 bar).
NOTE: Do not allow the pressure to exceed 250 psi (17.3 bar). If the pressure

exceeds 250 psi (17.3 bar), open the concentrate flow control valve until the
pressure gauge shows 250 psi (17.3 bar) or less.
As the machine purges the air and fills with water, the pressure will gradually
increase. You should see water flowing through the permeate and
concentrate flow meters. If you do not see flow, turn the machine off and

return to step 1.

NEVER ALLOW THE MACHINE TO OPERATE WITHOUT ADEQUATE WATER
PRESSURE. THIS CAN CAUSE SEVERE DAMAGE TO THE HIGH-PRESSURE PUMP.

15. Gradually close the concentrate flow control 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 250 psi (17.3 bar). If you reach 250 psi (17.3 bar) 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 250 psi (17.3 bar).

The concentrate flow control valve has a drilled orifice to ensure a

predetermined amount of flow and pressure in the closed position. This orifice
is sized to operate the machine at 75% recovery.

16. With the concentrate flow control valve fully closed and the pressure below

250 psi (17.3 bar), gradually close the recycle flow control valve until the
pressure reaches 250 psi (17.3 bar).

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 17 will explain the necessary

steps.

17. Your machine is equipped with flow meters and a pressure gauge that will

assist you in setting alternate flow rates for variable recoveries. If you wish to
operate at a recovery lower than 75% you must ensure that the flow rates for
the permeate and concentrate are at desired levels. Some minor adjustments

in the concentrate and recycle flow control valves may be necessary.

See Table 1 for specified flow rates for various machine recoveries. When you
have selected your desired flow rate, gradually adjust the concentrate flow
control valve to achieve desired flow and use the recycle valve to bring the
operating pressure up to 250 psi (17.3 bar).
