Water Quality Setpoint
The water quality setpoint can be adjusted from 0-999. If set to 999, the water quality lamp will always remain green. To
set the water quality setpoint, press the Setpoint key. The display will alternate between the setpoint and SP. Use a small
screwdriver to adjust the SP adjustment to the desired setpoint value. Press the Setpoint key to return the display to the
water quality display.
Calibration
To adjust the calibration of the water quality, measure the water with a meter calibrated to a known standard. Using a
small screwdriver, adjust the CAL adjustment to get the correct reading on the display.
Initial System Start-Up
Refer to the P&ID on page 31 for valve and gauge locations.
Note:
Pump throttle valve CV-1 is only available on systems with Sta-Rite Multistage pumps
(L-14A,
L-24A: 50Hz Only; L-34A, L-44A, L-54A, L-64A All Voltages)
. Systems with Procon pumps do not have CV-1.
1. Direct the product water tubing to drain.
2. Open the feed water supply valve.
3. Open the system pressure (pump throttle) control valve (CV-1) fully counterclockwise (if applicable). Open the
concentrate control valve (CV-2) fully counterclockwise. Close the recycle valve (CV-3).
4. Press the power button to turn the system on. Note inlet water pressure must be at least 40 psi.
Caution:
If the pump chatters loudly, it is starving for water (cavitating). Turn the unit OFF
immediately to prevent pump damage. Correct the low pressure condition before proceeding.
5. If incoming pressure is too high, an inlet pressure regulator (not included) may be installed. This should be set at
40 psi.
6. Some fittings may have loosened during shipment. Check for leaks at all tube fittings and threaded joints.
7. Allow the unit to run for at least 30 minutes to flush the preservative solution from the system.
8. Once the preservative solution has been flushed from the system, shut down the system by pressing the ‘power’
button and redirect the permeate flow to desired product storage tank or down-stream equipment.
9. Restart
system.
