UATREAU TOUCH
INSTALLING THE QT553-B
————————————————————
STEP 1
Install the Thermostatic valve in
accordance with instructions, onto
the hot and cold mains. Using the John
Guest 1/2” - 3/8” reducer included in your
instillation kit, connect to the temperature
controlled outlet port (this will maintain
temperature at or below 42C).
Using the 3/8” blue pipe enclosed cut a
length to feed the hot mains water inlet on
the left side of the QT553-B module.
As part of this installation you will also
install a separate cold water supply with
a 1/2” isolation valve. This will control the
cold water mains feed to the left and the
smaller 1/4” cold feed into the front right
hand side of the QT553-B.
Connect a John Guest 1/2” -3/8” reducer
to this cold isolation valve and run a length
of blue 3/8” PE pipe ready for connection
to the cold mains water inlet alongside the
hot water inlet.
To create the secondary cold inlet feed
connect the 3/8” reducing T into the same
3/8” pipe at the closest point to isolator
and run a length of 1/4” pipe to the pure
inlet on the right hand side of the QT553-B.
Also connect the 1/4” isolation valve just
before the inlet. This will be sued for control
purposes.
STEP 2
With the QT553-B (boiler control module)
module on the right hand side of the
cupboard connect the thermostatic hot
and the mains cold connections using
the 3/8” blue PE pipe enclosed in your
installation kit.
Attach the blue 3/8 pipe enclosed to the
3/8 ports at the back left hand side of the
unit. Note that hot is furthest to the back
and cold is attached in front of the hot.
Both ports are laser etched hot / cold. Turn
both the hot and cold services until 50%
open. These connections feed a robust,
one piece manifold. Whilst a water tight
seal should be instantly achieved with the
push fittings, its important to observe and
listen for any water escaping.
The manifold is very robust and should
cope with transit but, in the event of the
system being dropped damage may
occur. In this event call your supplier and
request a new 553 manifold.
Now connect the cold water feed to the
top front right hand side of the 553-B.
using the 1/4” PE pipe provided. The speed
fitting will make a water tight 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.
If using a purifier to feed the system ensure
it has been commissioned with a 50psi
