This device prevents any wastewater from the
drain from reverse migration into the tap sys-
tem. It will be required by law in most countries.
INSTALLING QUATREAU SMART TAP™
INSTALLING AIRGAP DRAIN
SECTION THREE
INSTALLING THE TYPE AA
(AIR GAP) DRAIN
Your kitchen design will, of course, dictate
where you can install it safely.
4. The standalone tap should be sited on the
right-hand side of the sink with the spout far-
thest away (at the back) from the user or to the
back of the sink in a front-to-back orientation.
Before you start cutting, ensure that you have
set up a jig or a template device to prevent the
drill bit from moving when you cut.
If you purchased a stand-alone SmartTap™,
(unless special order), the icons will be orien-
tated to sit on the right-hand side of the sink
with the spout facing to the left over the sink.
The spout will be to the back of the control
panel.
6. Once the hole(s) is prepared, remove any
rough edges or bits of wood and place the tap
carefully into the hole, ensuring that the comms
cable is dropped into the hole first to prevent
damage.
8. Using the fixing nut (and washer if required)
provided, gently tighten to the underside of the
worksurface to prevent the tap base (or drip
tray) from moving. Once secure, remove any
excess silicone using a wet finger to run around
the edges pushing into the corners to create a
smooth finish. If the drainer appears to be lifting
on one side use a weight to hold it down while
the silicon sets.
1. Open the drain-off kit and type AA air gap
found in the installation kit. Be careful not to
lose any parts. Locate a suitable position on
the approved sanitary drain where the saddle
clamp can be fixed and ensure that the check
valve, elbow and air-gap device can sit vertical-
ly without obstruction.
2. Place the saddle valve in a position to allow
proper gravity fall from the faucet through the
air gap into the saddle valve.
3. Fix in place and connect the elbow, check-
valve, and finally, the AA airgap fitting and check
it fits. The top of the AA airgap should be at
least 6”(152.4mm) below the work surface to
ensure a gravity fall when connected to the
VenturiT™ onto the SmartTap™ boiling pipe.
4-6”(101-152mm) below the work surface (this
comes later).
4. When you are happy, the parts all fit, and the
air gap fitting is fixed, pointing directly upward.
Remove components and use the piercing
blade or a drill to cut through the waste pipe.
This part connects to the internal thread on the
saddle clamp. Once cut, remove this cutting de-
vice completely and discard it.
7. Run a bead of silicone around the edge of
the holes or around the edge of the tap base
unit and carefully place the SmartTap™ into the
worksurface ensuring that the comms cable is
hanging free underneath the worksurface.
5. If installing the integrated drip tray (QST-D),
locate it in the center of the worktop with con-
trols to the right-hand side.
THE COMMS CABLE
CONNECTS INTO THE
BACK-LEFT SIDE OF
THE QST553-B. THE
QST553 MUST BE
LOCATED CLOSE TO
THIS CABLE WITH-
OUT CAUSING IT TO
STRETCH.
5. Now assemble the drain-off kit with the el-
bow, check valve, and AA fitting tightening all the
collars to create a firm fix. The check valve and
the airgap creates two (2) different forms of
backflow prevention.
