DRAIN FLOW CONTROL
The flow control is required for proper operation of the
Reverse Osmosis system. See Fig. 27. The flow con-
trol, located inside the push-in elbow fitting on the
drain port of the Reverse Osmosis filter assembly,
keeps water flowing through the membrane at the
required rate. This ensures that the system produces
the best quality product water.
Periodically check the flow control to be sure the small
hole through it is clean and unrestricted.
If the flow control requires service, review the explod-
ed view in Fig. 27. Assemble and disassemble as
shown. If the flow control remains in the manifold when
the push-in elbow fitting is removed, you will need to
remove the drain port's collet and o-ring, as shown in
the next section, to retrieve it.
CHANGE COLLET AND O-RING
1. Remove the collet and o-ring from the fitting with a
small screwdriver. Do not scratch the internal walls
of the collet port. See Figs. 28 & 29.
2. Clean collet port, lubricate with silicone-based lubri-
cant, and insert the o-ring seal into the bottom of the
port. See Figs. 28 & 29.
3. Push the collet inward until it locks in place. See
Figs. 28 & 29.
CHANGE BATTERY
To change battery, complete the following steps.
1. Remove the screw on the right side of the faucet
base. See Fig. 30.
2. Press the battery housing upwards from the front
faucet base until it releases from the faucet base.
See Fig. 30.
3. Replace the battery (CR 2032 or equivalent). Place
battery into the holder with the positive (+) side fac-
ing the back of the holder.
4. When the battery is installed the LED will flash six
times and turn off. This indicates the battery is fully
charged. After the six flashes, the timer enters the 6
month time cycle. If it repeatedly flashes two times,
it is not a fully charged battery.
5. Re-install the battery housing and firmly tighten the
mounting screw. See Fig. 30.
