5. The boiling, chilled and sparkling supply must
have the venturi T included
(see diagram below)
. The
venturi T requires a type AA drain connection in
accordance with your local plumbing code.
Take feeds from the thermostatic mixing valve,
which is fed by the mains hot and cold feeds.
Connect the john guest 1/2” (12.7mm) to 3/8”
(9.52mm) reducer from the installation kit to
the temperature-controlled outlet port.
This is where you will set your hand-hot tem-
perature and flow rate to the system. We rec-
ommend adding adjustable valves before the
thermostatic valve; this will allow for flow rate
adjustment. (this will maintain the temperature
at or below 111.2°F/44°C).
Using the 3/8” (9.52mm) blue pipe enclosed
cut length to feed the hot mains water inlet on
the left side of the QT553 module.
As part of this installation, you will also install a
separate cold water supply with a 1/2” (12.7mm)
isolation valve. This will control the cold wa-
ter mains feed to the left and the smaller 1/4”
(6.35mm) cold feed into the front right-hand
side of the QT553.
Connect a john guest 1/2”-3/8”(12-9.52mm)
reducer to
this cold isolation valve and run the length of
blue 3/8” (9.52mm) PE pipe ready for connec-
tion to the cold mains water inlet alongside the
hot water inlet.
STEP 2
The QT553 module on the right-hand side of
the cupboard connects the thermostatic hot
and the cold water supply connections as per
previous step (step 1).
Once you have connected the feed from the
thermostatic mixing valve to the QT553 unit,
turn both the hot and the cold services until
50% open.
These connections feed a robust, one-piece
manifold. While a watertight seal should be in-
stantly achieved with the push fittings, it’s im-
portant to observe and listen for any water es-
caping.
Now connect the cold water feed to the right-
hand side of the QT553 using the 1/4” (6.35mm)
PE pipe provided. The speed fitting will make a
watertight seal when the pipe is pushed firmly
into the port labeled PURE INLET.
Note
that this can be fed by a purifier or mains
cold water.
Ventilation will ensure your chiller performs to
its specification
.
Failure to install this will void
the warranty on this module.
The Quatreau chiller carbonator is sited next to
the QT553. Usually, this will be to the left of the
QT553 use the 1/4”PE pipe provided to inter-
connect the QT553 and CS20 units as follows.
• From the QT553 to the CS20
• H2O OUT to WATER IN
• CO² OUT to CO² GAS IN
• CARB IN to SODA WATER OUT
• CHILLED IN to STILL WATER OUT
Ensure that you leave a 1” (25.4mm) gap around
the sides of the chiller unit. This enables ventila-
tion and air movement, without which the sys-
tem will not chill correctly.
If using a purifier to feed the system, ensure it
has been commissioned with a 3bar/50psi re-
act switch before connection. You will use sev-
eral liters of water to commission the Quatreau
system, so it is sensible to commission with
mains water first, then convert to pure once
the system has been purged.
Before installation of the chiller unit, refer to
the cutting template enclosed with the chiller. A
ventilation hole is cut in the cupboard base, and
the vent pipe runs to and cut into the kickboard
using the ventilation grill.
See Pre-Installation specification for more in-
formation.
