4. Installing the Drain Clamp
NOTE: If you have a single-basin sink with a disposal unit, call Technical Support
for options.
NOTE: Before installing the drain clamp, check the drainpipes under the sink
for corrosion. Corroded pipes should be replaced before continuing with
installation.
(A) Attach the drain clamp to a vertical section of the drainpipe, about 6" above
the trap. Make sure the opening on the drain clamp is facing towards the
drinking water faucet.
(B) Using the fitting hole of the drain clamp as a guide, drill a 1/4" hole through
one side of the drainpipe.
(C) Remove the drain clamp from the drainpipe and enlarge the hole with a
3/8" drill bit. Use a file to remove rough edges from the drilled hole.
(D) Make sure the black rubber gasket is adhered to the inside of the drain clamp
and place the drain clamp assembly over the drilled hole. Look through the
hole and position the clamp so that the center of the clamp hole is slightly
higher (about 1/16") than the center of the drilled hole. Tighten the clamp
securely.
(E) Screw the plastic compression nut onto the drain clamp until hand-tight.
5. Connecting the Faucet to the Drain
This is a gravity drain line. Any loops, kinks or sharp bends must be
CAUTION
eliminated before proceeding. Failure to create a straight line to the
drain may result in reject water leaking through the air gap in the
faucet onto the countertop and below the faucet.
(A) Align the larger reject 3/8" red tubing from the faucet with the compression
nut on the drain clamp. Create as straight and smooth a path as possible with
the tubing. Do not kink tube. Cut the tubing squarely and remove any internal
and external burrs. Insert inner tube insert (white cone) into end of 3/8" red
tubing. Remove compression nut from the drain clamp. Place compression
nut on end of 3/8" red tubing.
(B) Insert the tubing into the drain port until it stops. Tighten the compression nut
with fingers, then tighten 1 to 2 turns with a wrench to secure tubing to drain
port.
6. Mounting the System
When selecting a mounting location of the system and tank, take
WARNING:
into consideration the length of tubing required for connection
between components. Some installation sites may require more
tubing than provided in the kit.
(A) Select a location under the sink, or other suitable area where the system will
be installed.
NOTE: The system carton can be used to determine the operational footprint
required for installation of the system and replacement cartridges.
(Figure 6)
(B) Mount the system vertically. Ensure mounting is level. Remove filter
cartridges for easier access to bracket mounting holes. Place a pencil mark
in the upper slots of the bracket mounting holes. (Figure 4b). Alternate
mounting option: If mounting the system near the floor, place the pencil
marks above each of the mounting holes on the bracket to ensure enough
space resides below the cartridge and the floor for cartridge replacement
(Figure 4c). Use the 3/32" drill bit to create pilot holes for mounting.
The system should be mounted to a firm, solid surface that is
WARNING:
able to support the weight of the system.
7. Connecting the Faucet to the System
(A) Determine the length of plastic blue tubing needed to connect to the outlet
(right) side of the filter from the faucet. Be sure to allow enough tubing to
prevent kinking and cut the tubing squarely. Use a marker to mark one end of
the tubing 5/8" from the end. Wet the end of the 3/8" tube and push into the
outlet (right) connection of the system up to the mark.
Do not bend or crimp tube while inserting.
CAUTION
(B) Gently pull back on the tube to ensure it is connected properly.
