Up Flow Membranes
1. Loosen bolts on bottom end cap clamp and slide the clamp down out of the
way.
2. Firmly grasp housing end cap(s) and using a rocking motion, remove them
from the housing(s)
3. Remove plastic wrapping/packaging from the membrane element(s).
4. Remove membrane brine seal from membrane. (Figure 18)
5. Insert membrane into housing allowing brine seal end to extend below
housing.
6.
Re install brine seal noting orientation direction on flow label. Lightly lubricate
the membrane brine seal and all O-rings located in the membrane housing
caps with a good quality, silicone O-ring lubricant (
DO NOT
use petroleum-
based lubricants).
7. Re-install the lower end cap assembly into housings using rocking motion.
8. Re-install the lower band clamp and snug bolts equally to maintain an even gap between the clamp halves.
9. Ensure the membrane product adapter is fully seated inside the housing cap at the bottom of the housing.
10. Repeat steps 10-18 for remaining membranes.
11. Re-install the top housing end cap assembly into housing(s) using rocking motion.
12. Re-install the band clamp and snug bolts equally to maintain an even gap between the clamp halves.
13. Repeat steps 20-21 on any remaining housing end cap assemblies.
14. Turn on water supply.
15. Turn on power.
16.
Perform system startup and flush procedure (
See 2.4. System Startup and Flush Procedure).
17. Inspect system for leaks.
!
MEMBRANES ARE SHIPPED WITH AN ANTI-BACTERIAL PRESERVATIVE. OPERATE THE SYSTEM FOR 1 HOUR THE
TO ASSURE MEMBRANE HAS BEEN COMPLETELY FLUSHED. DO NOT USE WATER PRODUCED DURING THIS RUN-IN
PERIOD.
3.7. Monitoring System Performance
Your system will be operating at its peak performance after about 24 hours of operation. You should develop a daily log to track pre-filter
pressure, post filter pressure, system pressure, feed water TDS, permeate TDS, permeate flow rate, and waste flow rate. This will allow
you to see any developing performance trends or alert you to system changes that will require you to intervene. It will also be helpful for
your dealer or Waterite technical personnel to have this information available to help troubleshoot your system, should it be necessary.
The table provided in Section 8 will help you get started.
The TDS meter should be recalibrated every 6-12 months using a commercially available calibration solution. Contact your dealer for
more information.
3.8. Auto Flush Feature
For feed water TDS above 1000ppm, it is strongly recommended that a periodic flush be done to remove sediments and mineral build-
ups from the membrane surface. The auto flush program purges high concentrations of dissolved solids out of the system. This helps
minimize scale and fouling. To enable auto flush, see
2.2. Controller Programs and 2.3. Switching Between programs.
