Maintenance continued

8.
Make up a sanitizing solution of 1/3 teaspoon (1.5 ml) of household bleach and 1 gallon
(3.8L) of clean, potable water in a bucket. Mix solution well.
NOTE:
Excessive concentrations of bleach may damage plastic and rubber
components. Rinse all parts that contact bleach thoroughly with clean, potable
water.
9.
Lightly lubricate each housing o-ring with a coating of clean silicone grease. With two
fingers, press each o-ringsecurely into groove below the threads of the housing.
CAUTION:
The housing o-ring provides the water-tight seal between the cap and the
bottom of the housing. It is important that the o-ring be properly seated in the
groove below the threads of the housing or a water leak could occur.
10.
Add one cup or 8 oz. (236 ml) of sanitizing solution to each filter housing and install them
onto the manifold. (DO NOT INSTALL FILTERS OR MEMBRANE AT THIS TIME)
NOTE:
TIGHTEN FILTER HOUSINGS BY HAND ONLY. DO NOT USE WRENCH.
11.
Slowly open source water at the saddle valve until completely open.
12.
Open the drinking water faucet. Close the faucet as soon as water begins to flow from the
spout.
13.
Wait 5 minutes, then close the source water at the saddle valve.
14.
Wait 25 minutes, then open the drinking water faucet and let the water flow to drain.
NOTE:
Do not attempt to remove the filter housings until the water flow stops.
15.
Remove the filter housings and dispose of the water. Rinse the housings thoroughly with
clean, potable water.
16.
Place the empty post-polishing filter housing on the left side of the unit. HAND TIGHTEN
ONLY.
NOTE:
DO NOT put the USL-CC (post-polishing) filter into the housing at this time. It will
be put into the housing after the membrane has been flushed.
17.
Insert the USL-NCR (pre-filter) cartridge into the right housing and attach to the right side
of the unit. HAND TIGHTEN ONLY.
NOTE:
Use the silicone lubricant supplied with the membrane for Steps 18,19 & 21.
18.
Lightly lubricate the inside of the membrane (middle) threaded cap. (See diagram 1)
19.
Lightly lubricate both sides of the brine seal. (See diagram 2)
20.
Gently slide the membrane into the housing. Pressing on the central tube of the membrane
from the top only, push the membrane fully into the housing until the central tube is flush
with the top of the housing. Be sure to push the membrane straight down into the housing.
If the membrane is not centered in the housing, the locking device will not fit properly.
21.
After the membrane is seated, lightly lubricate the two small o-rings at the end of the
membrane. Also, lightly lubricate both brine ring o-rings. (See diagram 1)
CAUTION:
The rubber o-rings provide the water-tight seal between the cap and the
housing. It is important that the o-ring be properly seated in the groove below
the threads of the housing or a water leak could occur.
22.
Insert, then turn the locking device counter-clockwise. Screw the housing back onto the
RO system until it is hand-tight. DO NOT OVER TIGHTEN.
23.
To complete the flushing of the membrane and USL-CC (post-polishing filter) and assembly
of the unit go to Step 14 System Startup on page 7.
