E. Install the R.O. Membrane
Disconnect the tubing from the end cap of the
membrane housing. Then, unscrew the end cap
from the membrane housing. Insert the membrane
as illustrated below. The o-rings on the product
water tube of the membrane MUST BE FULLY
SEATED in the membrane housing for proper
operation. Also make sure that the brine seal on the
membrane seals with no gaps or wrinkles inside the
membrane housing. Once the membrane is
installed, replace the end cap and reconnect the
tubing.
The RO membrane contains a special preservative.
To insure that all the preservative is flushed from
the system before use, DO NOT use the first two
tankfuls of water produced by the system.
F. Make Initial Tubing Connections
It is advantageous to make some of the tubing
connections at this time, since the under-sink work
area is not so crowded and access to the
components is easier.
G. Install the R.O. and Storage Assemblies
The R.O. assembly is usually mounted to the right
or left sink cabinet sidewall, taking into con-
sideration the space available and the tank
location. Generally, the tank is placed in the rear of
the cabinet while the R.O. assembly is positioned
toward the front for cartridge accessibility.
To mount the R.O. assembly elevate at least 2" off
the cabinet floor and, while keeping level, mark the
location of the mounting holes on cabinet sidewall.
Make small pilot holes with an awl or drill and screw
in the two mounting screws, leaving just enough
protruding to allow bracket mounting slots to slide
over them.
NOTE: If the cabinet sidewalls are not of solid
construction, the purification assembly can be set
on the cabinet floor and held against the sidewall
with the mounting screws.
The tank may be oriented either vertically or
horizontally. It is generally placed to the rear of the
cabinet but can be set in the front center (between
the sink basins) for ease of access if space permits.
H. Make Final Tubing Connections
With all of the components in place, the final tubing
connections can be made. When routing tubing
between components, several guidelines should be
observed.
Tubing runs should generally follow the con-
tour of the cabinets rather than interfere with
the cabinet storage area.
Strive for neatness and an orderly tubing
“flow” using fasteners (e.g. insulated
staples) to secure the tubing. Cut tubing to
the desired length.
Arrange the tubing so there are no sharp
bends and leave some “play” in the tubing
for ease of servicing.
Try to keep the tubing from the R.O.
assembly to the tank and faucet as short as
practical for good flow.
Be sure to install the Leak Stop Valve in the
feed water line next to, or under the RO
assembly. Note the arrow on the Leak Stop
Valve indicating the direction of flow.
Secure the valve with screws or double-
sided tape.
I. Install Ice Maker Hookup (optional)
Note: Check with refrigerator or icemaker
manufacturer for compatibility with your refrigerator
model. Some icemakers require higher line
pressure to operate properly; a pump model
(QCRO-50-PUMP or SRO-100) may be required.
Hooking up an ice maker involves connecting a tee
with shut off valve into the faucet tubing and routing
tubing over to the refrigerator. Do not hookup to
existing copper tubing.
Before turning off the existing tap water supply to a
refrigerator ice maker, always shut off the ice
maker first (usually by lifting the lever arm above
the bin to the upper most position). The ice maker
should only be turned on again after the R.O.
system has been drained several times and the
tank has a full supply of water.
