5. Prefi ll and Sanitize the Storage Tank (continued)
E) Thread ball valve onto tank.
F) Insert one end of 3/8” yellow tubing into ball valve.
G) Connect supplied 3/8” x 1/4” adaptor to other end of yellow tubing.
H) Connect free end of orange feed water tubing to 1/4” side of adaptor.
I) Open feedwater valve and tank valve and allow tank to fi ll (about 3 minutes).
J) To open feedwater valve, turn handle to the left (counterclockwise).
K) Turn off feedwater valve and tank valve.
L) Remove orange tubing from adaptor then remove adaptor from yellow tubing. The tubing may need to
be cut for removal due to line pressure. Refer to Figure 6.
M) Set tank aside for at least 15 minutes for disinfection.
6. Install the Drain Connection (Figure 4)
For basement installations, the drain saddle is generally not used. Instead, the RO reject line is routed so
that it drains into a laundry sink, fl oor drain or standpipe through an approved air gap.
Undercounter Installations:
The drain saddle assembly is designed to fi t around a standard 1 1/2” O.D. drain pipe. For smaller (lavatory
type) or larger (ABS pipe) drains, consult your Aqua-Pure
®
distributor.
NOTE: The drain saddle should always be installed above (before) the trap and on the vertical or horizontal
tailpiece. Never install the drain saddle close to the outlet of a garbage disposal or dishwashing drain be-
cause plugging of the RO drain line may occur.
A) Position threaded half of drain saddle at selected location and mark the spot through the opening.
B) Drill a 1/4” hole at the marked spot through one side of drain tailpiece.
C) Position both halves of drain saddle on drain pipe so the threaded opening lines up with the hole in the
drain pipe.
D) Use bolts and nuts to clamp drain saddle onto drain pipe. Do not overtighten and make sure that there is
equal space between saddle halves on each side. CAUTION: Overtightening could result in a cartridge
crack, which may lead to fl uid leaking.
E) Wrap PTFE tap on thread of drain saddle elbow and tighten into drain saddle. Orient elbow in the direc-
tion of RO faucet location.
7. Install the Faucet
NOTE: Undercounter installations require a faucet with faucet air gap module. See Figures 1 and 2.
A wide variety of RO faucet mounting situations can be encountered, the most common being stainless
steel and ceramic on metal sinks.
The faucet should be positioned so that it empties into the sink and the spout swivels freely for convenience.
If the sink already has a hole provided that can accommodate the RO faucet, then no drilling is required and
you can proceed to the section on mounting the faucet.
NOTE: Sprayers can be disconnected to provide a suitable hole for the RO faucet. A pipe cap or plug will
be required to seal the sprayer connection on the existing faucet.
• Before starting the undercounter installation procedure, inspect the condition of the drain piping, especially in
older homes where the traps and tailpieces can be deceptively thin and frail.
• Some state and local plumbing codes may prohibit the use of saddle-type valves and/or drain connections. See
page 2 for list of states. Optional feed valve assemblies can be purchased. See page 15 for further information.
