2. Peel back the bag from the cut end and use it as a holder to
insert the RO Membrane, O-Rings first, into the Membrane
Housing (see Figure 9).
3. Push the RO membrane into the housing until it seats. The end of
the membrane should be about 3/8” into the housing.
4. Check the O-Ring on the membrane housing shoulder to make
sure it is seated in place.
5. Screw the membrane housing cap back onto the membrane
housing. Firmly hand tighten the cap on the housing, but do not
overtighten it and do not use a wrench.
Flushing the System
1. Open the cold water supply valve and the Cold Water Saddle
Valve, allowing the water to enter your system.
2. Open the RO faucet and let it run for one hour.
3. Close the RO faucet and open the storage tank valve. Check the
system for leaks.
4. Put the RO unit under the sink.
5. Let the RO unit charge for at least 6 hours. Periodically check for
leaks. Then open the RO faucet and let the water run until the air
and carbon fines are out of the system. Close the faucet.
6. Let the system charge for approximately another 6 hours.
7. Open the RO faucet and let the water run until the water comes
out at a slow drip or stops. Close the faucet and allow the system
to fill.
Your system is now ready for use.
TDS MONITOR OPERATION
Once the drinking water system installation is complete, run water
from the RO faucet and watch the LED in the base of the faucet.
• A green light will appear if the product water TDS is below the
set point. No action is required.
• An amber light will appear if the product water TDS is above the
set point. Proceed with Steps 1 and 2 below.
1. Run a few cups of water through the faucet and see if the LED
changes to green.
2. If the color of the LED does not change, run the water until the
storage tank is empty.
Allow the tank to refill and recheck it. If the LED is still amber, the
drinking water system may require service.
• If the LED is blank, replace the battery.
PRE-FILTER CARTRIDGE CHANGE
(TO1 AND CB1)
NOTICE:
Do not disconnect any tubing for this operation!
1. Turn off the water supply either at the Cold Water Saddle Valve
or the cold water supply valve.
2. Close the valve on the storage tank.
3. Open the RO faucet until the water stops running; close the
faucet.
4. Pull the RO unit out from under the sink (don’t bring the storage
tank out) and put it in a shallow pan on the floor in front of the
sink.
NOTICE:
Do not disconnect any tubing!
5. Using the plastic tank wrench supplied, remove Pre-Filter Tanks
TO1 and CB1. Be careful – the tanks will be full of water.
6. Remove the used cartridges and dispose of them.
7. Check the tank O-Rings to be sure that they are seated properly.
Apply vegetable oil to the O-Rings.
8. Rinse the tanks with clear water (no soap) and wipe them out
with a clean rag or paper towel.
9. Put the replacement filter cartridges into the tanks and reinstall
the tanks.
NOTICE:
The
carbon
filter cartridge (dark grey) goes onto the
tank head marked TO1 (toward the prefilter inlet). The
CB
filter
cartridge (white) goes onto the tank head marked CB1 (toward
the unit outlet).
10. Screw the filter tanks onto the tank heads firmly hand tight.
NOTICE: Do not
use the wrench to tighten the filter tanks – you
could crack the tanks or the tank heads. Tighten them hand-
tight only.
POST FILTER REMOVAL AND
INSTALLATION
1. Note that the large end of the R200 Post Filter is on the same
end of the unit as the membrane housing cap. The new Post
Filter must be installed with the same orientation.
2. Disconnect the tubing from the old Post Filter (see Figures 5 and
6) and pull it out of the brackets holding it to the RO membrane
housing.
3. Insert the yellow tubing into the input end of the new Post Filter.
Push it in firmly until it stops (about 5/8” of tubing should go
into the connector).
NOTICE:
Before reconnecting the filter note the flow direction
arrow on the filter. Be sure it is installed correctly.
4. Insert the blue tubing into the output end of the new Post Filter.
Push it in firmly until it stops (about 5/8” of tubing should go
into the connector).
5. Snap the new Post Filter into its brackets on the RO membrane
housing (inlet end toward the Membrane Housing Cap).
6. Open the RO faucet, the valve on the storage tank, and the
water supply valve. Flush the system until the water stops run-
ning or slows down to a slow drip. This will flush the ‘carbon
fines’ (very small particles of carbon that are present in a new
cartridge) out of the system.
7. Turn off the faucet and check for leaks. Carefully tighten any-
thing that is leaking. Do not overtighten fittings.
8. Put the RO unit back under the sink and let it charge for at least
6 hours. After 6 hours, check for leaks. Open the RO faucet and
let the water run until the air and carbon fines are out of the
system. Close the faucet.
9. Let the system charge for approximately another 6 hours.
Your system is now ready for use.
