STEP 1 : Install Air-Gap Faucet (See Fig. 3)
The faucet (2640) may be installed on the counter-top or the sink, as
desired. For counter-top installation, position faucet on the counter-top
beside the sink where it will not be obstructed from above or below.
NOTE: The faucet has a 3/8" black drain tube and a ¼" grey drain tube
pre-attached to it. A flow restrictor is inserted at the end of the grey
tube. (fig 3A). CAUTION:
TUBE or the system will not be able to produce filtered water.
For laminate countertops, mark the location and drill a 7/8" hole.
Note: For granite or other stone countertops, hole should be drilled only
by a professional. Do not attempt to do this yourself to prevent breakage.
a) Insert the faucet tubing (1/4" grey and 3/8" black) first through the countertop hole
followed by the faucet with drain hole in faucet body facing sink.
b) Install slotted washer (2650-4), spacer (2650-5), bottom washer (2650-6) and lock-nut
(2650-7). Tighten lock-nut while someone holds the faucet so it does not turn.
c) Put a compression nut (1030-15) and a ring (1008-3) on one end of the blue tube
(2622) and push the sleeve (1603) into the end of the tube (see Fig. 3). Insert the tube
into the threaded stem of the faucet, and secure it in place by tightening the
compression nut with a wrench. Have someone hold the tap to prevent it from turning
while tightening the nut.
STEP 2: Make Drain Connection
a) Mark a spot on the vertical drain pipe under sink and drill a 3/8" hole in it, preferably
facing direction of faucet. Make sure not to drill right through the other side of the
pipe.
b) Peel the protective film off the sponge gasket and apply to inside of drain saddle
(2618), using care to align sponge gasket hole with drain saddle hole.
c) Mount the drain saddle on the drain pipe and align the drain saddle hole with the 3/8"
drilled hole (use a flashlight to see clearly). Use a drill bit or any narrow straight object
to confirm that the two holes are aligned. Tighten the saddle nuts and firmly secure
the saddle in place. Do not over-tighten. (see Fig. 4)
d) Mark the black drain tube 3/4" from end and insert firmly until mark touches the end
of the fitting.
e) Connect 3/8" black drain tube from faucet to drain saddle by inserting it firmly until it
can go in no further. CAUTION: This is a gravity drain line and should be as short as
possible (See Fig. 1) or water can leak out of the air-gap hole in the faucet. Cut off any
excess tube.
STEP 3: Mounting the main unit
Locate best side wall position for mounting unit under-sink near faucet.
NOTE: Leave a minimum of 5 inches clearance below sumps to allow for removal of cartridges. The higher and
closer to the front you mount the unit, the better it will be for regular maintenance/servicing.
a) Unpack unit and pull post-filter (IM200) towards front to expose mounting bracket (2613). Mark mounting bracket
screw locations using mounting bracket as a template and set unit aside.
b) Partially screw the two mounting screws (1011-0) into screw locations.
use round-head nuts and bolts (not supplied) to mount bracket. Install pre-filters and membrane as per
instructions below before mounting unit on the wall.
c) Remove wrapping from sediment pre-filter (HP1) and push it into the head carefully.
and rotate clockwise 1/8 turn to align the sump grooves with lugs on the head (2501) to lock position (fig 5).
Repeat procedure for second pre-filter (model CF2).
