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. DO NOT REMOVE THIS OR CUT THE GREY 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.
