Step 5. Install the Drain Saddle Assembly
1.
Select the location to install the drain saddle assembly. This is usually on the sink drainpipe and needs to
always be located above the “S” trap.
2.
Position the drain saddle assembly in the selected location and mark the spot through the threaded outlet
with a pencil or marker
3.
Drill a ¼” hole at the marked spot. Strip the backing paper from the adhesive side of the saddle gasket and
position on the inside of the drain saddle, aligning the hole with the threaded outlet. Attach the drain saddle
to the drainpipe, aligning the push-on port with the drilled hole. Tighten the clamp snugly. DO NOT OVER
TIGHTEN.
4.
The black drain tube may be inserted directly into the push-on drain port, using instructions in Step 8. below.
Do not attach poly tube at this time.
Step 6. Install the Tank Valve, Preparing the Storage Tank
1.
Wrap the threaded storage tank nipple with two wraps of Teflon tape. Thread on tank shut- off valve until
snug. Using the wrench, turn an additional ¼ turn. DO NOT OVER TIGHTEN. Open tank valve to the fully
open position.
Step 7. Mounting the RO Unit
1.
While holding the RO unit in its mounting position, mark the holes for the wall screws. Using a 1/8” bit, drill
the pilot holes for the screws. Screw in the mounting screws leaving ¼” protruding. Hang the RO mounting
bracket on the screws and tighten.
2.
If the unit is to be mounted on wallboard, use plastic screw anchors, available at any builder’s supply and
follow the manufacturer’s directions.
3.
DO NOT INSTALL FILTER CARTRIDGES AT THIS TIME.
Spin the filter housing bowls on to the RO unit
and hand-tighten.
Step 8. Connect the System Tubing
!
READ THIS SECTION CAREFULLY. MOST SYSTEM LEAKS ARE CAUSED FROM
IMPROPERLY COMPLETED PUSH-ON JOINTS.
Making and securing a push on connection is simple. First, the tubing should be cut
square and any burrs or rough edges removed. Insert the tube firmly and push until
the tube end contacts the stop. Gently tug the tube backwards to assure a secure
connection. To disconnect, pull the tube while pushing in the collet ring. The joint
may be used over and over again, if necessary.
1.
Connect the cold water supply valve to the first filter housing water inlet push-on fitting (marked “water
inlet”), after cutting the ¼” clear tube to the length required.
2.
Connect the black ¼” tube (marked “to drain”) to the Drain Saddle push-on connection (your black drain
tube is pre-attached to your RO). Please note that the drain line flow restrictor has been installed INSIDE
the black drain tube at the waste elbow, on the membrane housing. Place the storage tank in the location
you have chosen for it. Using the clear ¼” tube connect the system fitting marked “to tank” to the tank valve.
Connect the ¼” tube attached to the faucet to the system fitting marked “to faucet”. If the tubing is not pre-
attached to the faucet, cut the 3/8” clear tubing to the desired length and attach the tube to the fitting at the
base of the faucet shank to the fitting marked “ to faucet” on the RO unit.
3.
You may find that your unit does not have labels attached to indicate the water line and drain line
connections. The photos below are labelled with the correct locations for the water and drain connections.
