Installation Continued
10. Connecting the Saddle Valve
(A)
Locate pre-installed white plastic tubing found on the left hand side of the RO system.
Slide the brass compression nut onto the tubing, followed by the white plastic ferrule. The
long tapered end of the ferrule should face towards the end of the tubing and the tubing
should extend through the ferrule about 1/4-inch. Place white insert into end of tubing.
(B)
Insert white plastic tubing into saddle valve and hand-tighten compression nut. Using a
wrench, tighten nut 1 to 1 1/2 turns.
11. Installing the Membrane
(A)
Using the housing wrench, unscrew the middle (membrane) housing.
NOTE:
Do not unwrap the tape around the membrane; it is part of the membrane. Do
not squeeze the membrane.
(B)
Turn locking device clockwise to remove. Grasp the membrane by the central tube (the
end with the two o-rings). Before insertion, lightly lubricate the brine seal with the silicone
lubricant (included with membrane).
(C)
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.
After the membrane is seated, lightly lubricate the membrane o-rings with a small amount
of silicone lubricant.
(D)
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.
CAUTION:
The housing o-ring provides the watertight 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.
12. Faucet Operation
(A)
For controlled water flow, push the handle down.
(B)
For constant water flow, lift the faucet handle to lock it in the open position.
13. Battery Installation (RO-3500 only)
(A)
Remove manifold cover.
(B)
Plug battery into leads.
(C)
Place battery in holder at the front of unit and replace cover.
14. System Startup
NOTE:
The reverse osmosis membrane is treated with a food grade sanitizing agent
that may cause an undesirable taste. Although it is not harmful, it should be
flushed from the system.
NOTE:
The post-polishing filter may contain fine black carbon particles. These fines are
harmless, but may make the water appear gray in color. The carbon fines are
flushed from the system with the first tank full of water.
NOTE:
The RO system does not produce a high volume of water on demand as an
ordinary filter does. Water is produced at a slow, drop-by-drop rate. The system
requires about 6-12 hours to fill the storage tank. As water is taken from the
tank, the system automatically starts the cycle of replacing the water and then
stops water production when the tank is full.
CAUTION:
Visually check the entire system for leaks. Remove the manifold cover and
check the top of the manifold for leaks. If a leak is present, see Troubleshooting
on page 12.
(A)
Turn off valve at top of storage tank.
(B)
Turn on the cold water supply.
(C)
Completely open saddle valve until it comes to a stop.
(D)
Lift the faucet handle to lock it in the open position and let it drip for 30-minutes.
NOTE:
On the Model RO-3500, if the test button is pushed during the first 30-minutes of
flushing, you may get an amber rather than a green light indication. This is due
to the disinfectant agent being flushed from the membrane and is not a problem.
(E)
Close the saddle valve and wait for the faucet to stop dripping. Place a tray under the
system and remove the left (post-polishing) filter housing. Dump the water from the
housing into the sink and insert a white post-polishing filter with the black gasket end
facing up. Check the housing o-ring to make sure it is properly seated and screw the
housing back onto the manifold. HAND TIGHTEN ONLY.
