Step 2a:
Inlet/Supply Connection to Unit:
Orange/Red tubing
Connect the installed orange/red tubing from the installed Inlet/Supply Connection to the location
of the unit labeled “FEED”. This is the raw supply water into the system.
• For all 3-& 4-Stage Units, “FEED” is into the “Pre-Filter” housing on the bracket
• For all 5-Stage Units, “FEED” is into the “Sediment” housing on the bracket
Step 2b:
Faucet Connection to Unit:
Blue tubing
Connect the installed blue tubing from the installed dispenser/faucet to the location on the unit
labeled “FAUCET”. This is the filtered water from the system.
• For all 3-Stage Units, “FAUCET” comes from the “Postfilter” housing on the bracket
• For all 4-Stage Units, “FAUCET” comes from single quick connect fitting on the In-Line
“Postfilter” on top of the unit
• For all 5-Stage Units, “FAUCET” comes from the “Postfilter” housing on the bracket
Step 2c:
Unit Connection to Storage Tank:
Yellow tubing
Connect the yellow tubing from the location on the unit labeled “TANK” to the installed Tank
Valve on Storage Tank. The fitting on the unit will always be a 3-way, swivel “T” quick connect
fitting and may have an inserted sample yellow tube (remove sample).
• For all 3-Stage Units, “TANK” is located at 3-way, swivel “T” quick connect fitting at the back
of the bracket behind “Postfilter” housing
• For all 4-& 5-Stage Units, “TANK” is located at 3-way, swivel “T” quick connect fitting on the
In-Line “Postfilter” on top of the unit
Step 2d:
Unit Connection to Drain Connection(s):
Black tubing (1/4” and 3/8”)
Air Gap:
Connect the black 1/4” tubing from the location on the unit labeled “DRAIN” to the 1/4”
barb on the air gap adaptor. Then, connect the black 3/8” tube from the 3/8” barb on
the air gap adaptor to the 3/8” quick connect fitting installed on the drain saddle.
Non Air Gap:
Connect the black 1/4” tubing from location on the unit labeled “DRAIN” to the 1/4”
quick connect fitting installed on the drain saddle.
• For all Units, “DRAIN” is located behind the membrane housing at the back/top of the bracket at the
RSR control valve (this valve has 5 other installed connections). The “DRAIN” fitting may have an
inserted black sample tube
