14. On the front of the water heater unit, you
will find the gas regulator and instructions for
increasing the level of carbonation.
If you wish to feed your QT/QTS553-BCS
from an RO system.
1. First ensure that the storage tank is full.
2. Change the mains feed into the front right
side of the water heater to your RO feed.
3. The Optimum operating pressure from the
RO system to the water heater and chiller is
3Bar / 45psi.
4. Some RO systems have a maximum pres-
sure of 30 psi from the tank when full. You will
therefore need to install a delivery pump set
at 3Bar/45 psi to maintain optimum perfor-
mance.
15. When adjusting, make 1/4 turn adjust-
ments in the desired direction (+/-).
16. After an adjustment, repeat process 11
and 12.
Finally, adjust the flow rate of the mains hot
and cold down to a point where it doesn’t
splash when washing hands. The flow should
be smooth, calm and have the appearance
of a cone at the point where it falls from the
faucet.

SECTION D:

SECTION E:
QUATREAU TOUCH TAP ONLY
Optimum setting for mains Hot
& Cold
NOTE:
If you do not hear the pump activate
during this process, power off the chiller and
repeat processes 6-9.
NOTE:
Starvation of water will damage the
chiller carbonator pump. Do not run the
sparkling function if the RO system has run
out of water or pressure drops below 15psi.
This invalidates the 12 month warranty.
