on air gap faucet. Push on firmly until it seats.
E) Feed the air gap tubing and threaded nipple
through sink/counter mounting hole and orient the
faucet as discussed with the customer.
F) From below sink/counter assemble the white
spacer (open end up, open side toward air gap), flat
washer and hex nut on threaded nipple and tighten
by hand.
G) Back off on hex nut just enough to slide slotted
washer between white spacer and underside of
sink/counter (with open side of slotted washer closest
to air gap tubes).
H) After rechecking faucet orientation, tighten hex nut
(9/16" wrench or deep socket) until faucet feels secure.
I) From above the sink make any minor orientation
corrections by turning the faucet with a padded
adjustable wrench.
NOTE: Flats on chrome faucet may be used for
tightening with an adjustable wrench. Use care not
to mar chrome finish.
J. Make Initial Tubing Connections (Fig. 1)
For Basement Installation See Appendix
Undercounter Installation:
A) It is advantageous to make some of the tubing
connections at this time since access to the compo-
nents is much easier now that the undersink area is
less cramped.
B) The orange 1/4" tubing should already have been
connected to the feed valve with a 1/4" brass com-
pression nut, insert and plastic sleeve.
C) Connect 1/4" Blue tubing out of faucet to 3/8" x
1/4" union to 3/8" Blue tubing.
D) Connect the length of blue 3/8" tubing to faucet
fitting.
E) Route black 3/8" tubing from faucet air gap mod-
ule to drain saddle so that it slopes continuously
downward without loops or low spots. Cut to proper
length and connect to drain elbow by pushing tubing
through nut then hand tightening nut onto body.
F) Connect length of yellow 1/4" tubing to "Tank"
connection on purification assembly.
K. Install The Purification Assembly And
Storage Tank
For Basement Installation See Appendix
Undercounter Installation:
The purification assembly is usually mounted
to the right or left sink cabinet sidewall, taking into
consideration the space available and the tank loca-
tion. Generally, the tank is placed in the rear of the
sink cabinet while the purification assembly is posi-
tioned toward the front for better accessibility.
To mount purification assembly elevate it at
least 2" off the cabinet floor, while keeping level,
mark the location of the mounting holes on the cabi-
net sidewall. Make small pilot holes with an awl or
drill and screw in the two mounting screws, leaving
just enough protruding to allow bracket mounting
slots to slide over them.
NOTE: If the cabinet sidewalls are not of solid con-
struction, the purification assembly can be set on
the cabinet floor and held against the sidewall with
the mounting screws. However, the purification
assembly will then need to be lifted from mounting
screws in order to remove filter housings.
The tank may be oriented either vertically or
horizontally. It is generally placed to the rear of the
cabinet but can be set in the front center (between
the sink basins) for ease access if space permits.
L. Make Final Tubing Connections (Fig. 1)
For Basement Installation See Appendix
With all of the components in place, the final
tubing connections can be made. When routing tub-
ing between components, several guidelines should
be observed.
• Tubing runs should generally follow the contour of
the cabinets rather then interfere with the cabinet
storage area.
• Strive for neatness and an orderly tubing "flow"
using fasteners (e.g. insulated staples) to secure
the tubing.
• Arrange the tubing so there are no sharp bends
and leave some "play" in the tubing for ease of
servicing, then cut tubing to the desired length.
• Try to keep the tubing from the purification assembly
to the tank and faucet as short as practical for good flow.
Undersink Installation
A) Connect orange 1/4" tubing from feed water
valve to "Feed" connection on purification assembly.
B) Connect blue 3/8" tubing from faucet to the
"Faucet" connection on purification assembly.
