8. Place the black housing O-ring on the housing rim and carefully screw
the lid back on to the base. (Fig. D)
9. Reconnect the black tubing to the membrane feed push fitting.
10. Unscrew the rightmost housing and remove the DI cartridge. Screw the
empty housing back on and hand-tighten.
11. Turn the system on and run both the product and waste water lines to a
drain for one hour.
12. Using the built-in TDS meter, determine the membrane rejection rate.
The system must be running to perform this step. (See “Using The Three-
Probe TDS Meter” on page 8 and “Membrane Rejection Test” on page 11.
You may skip step 2 on page 11 as the system has already been running.)
13. If the membrane rejection rate is 96% or higher, turn the system off and
reinstall the DI cartridge.
NOTE: Make sure the DI cartridge is in the
correct orientation and that the rubber
gasket is positioned correctly. Hand-
tighten the housing only. Use of the
included filter wrench is not necessary
or recommended for tightening the
housing.
14. If the rejection rate is below 96%, run the system
for another hour and repeat step 12.
15. The system is now ready for use.
