INTRODUCTION
————————————————————
The Q-C and Q-CS units are direct chill
cooler systems designed to provide
chilled water by passing water through
a stainless steel water coil in the “cold
block”. Additionally Q-CS units are
designed to provide chilled carbonated
water.

INSTALLATION AND COMMISSIONING
——————————————————————————————————————————
Locate the machine in a suitable enclosure, ensuring that there is suitable ventilation.
Care must be taken to ensure that hot air from the exhaust vent is not recirculated into
the air intake. This will have an adverse effect on performance and will reduce fridge life.
During operation air is drawn into the unit through the ventilation openings in the base
(and unit sides for the Q-C20) and then exhausted through the ventilation openings to
the rear of the unit.

NOTE: At this stage do not connect the
unit to the electrical supply.
————————————————————
• Using 1/4” PE pipe, connect the
‘Water Out’ port, found on the front
right of the chiller, to the inlet on the
Quatreau system. This is located on
the left side of the system as you look
at it.
• Connect the ‘Water In’ port of
the chiller to the H2O port of the
Quatreau system.
• Check that the interconnection to the
Quatreau tap is fixed in place then
dispense water from the Quatreau
tap to purge air from the chiller.
• Once all air has been purged from
the system, connect the unit to the
electrical supply and turn on. The
compressor and fan will start
• After approximately 5-10 minutes,
the compressor and fan will stop as
the chiller has reached its normal
operating temperature.
NOTE: The time taken for the chiller to
reach operating temperature will vary
depending on ambient temperature,
humidity and the temperature of the
incoming water supply.

• Connect the ‘Water In’ port of the
chiller to the “H2O OUT” port of the
Quatreau Boiler system.
• Connect the Co2 Cannister (Set at
40-45 psi – 3 Bar).
• Turn water on.
• Using the Quatreau Tap, activate
the chilled water function until all
the air has been purged from the
system and a clean flow of water is
observed.
• Power system on and then
Immediately Select and then
Deselect the Sparkling Function. This
will allow the pump to receive the
water it needs.
• Once the pump has finished running
10-20 Seconds, power down the
Chiller Unit.
• Purge Co2 Water through the tap for
10 Seconds by selecting the Sparkling
Function.
• Power system on again and then
Immediately Select and then
Deselect the Sparkling Function. This
will allow the pump to receive the
water it needs.
• After approximately 10 minutes,
the compressor and fan will stop as
the chiller has reached its normal
operating temperature.
• The Chiller carbonator Unit is
commissioned.

SODA FLOW RATE ADJUSTMENT & UNIT
CLEANING
————————————————————
The Soda flow rate is factory set to
dispense at 30 ml per second at a
gas pressure of 2.7BarG. However, if an
alternative flow rate is required follow the
steps below:
1. Locate the flow adjuster screw on the
side of the unit.
2. To increase the flow rate turn the
screw anti-clockwise.
3. To reduce flow rate turn the screw
clockwise.
4. Adjustments can be made with either
a large flat head screw driver or with a
6mm Alan Key.
5. It is recommended to make
incremental changes of no more
than a 1/8th of a turn at a time until
desired flow rate is achieved.
————————————————————
GENERAL CLEANING – OUTER CASING
————————————————————
Important: It is recommended that the
procedure should be performed at least
every 6 months.
Condenser
At regular intervals, determined by local
environmental conditions, the condenser
should be thoroughly cleaned with a
small stiff brush and/or a vacuum cleaner.
Do not use screwdrivers or other sharp
implements which may puncture the
tubes and damage the fins.
Warning: Failure to clean the condenser
can shorten the life of the compressor
causing premature failure of the unit.
Outer Panels
Clean the outside panels, pay particular
attention to the edges of the panels
where spillage could have ingressed
and the area around the base of the
unit. If necessary, remove the unit and
thoroughly clean around the base and
floor.
Sanitisation
Important: It is recommended that the
procedure is performed during initial
installation and at least every year at time
of service.
————————————————————
PREPARE THE UNIT
————————————————————
For this procedure you will need a
Pureh2o3 sterilisation system from The
Pureh2o Company.
1. Disconnect the power supply to the
chiller unit.
2. solate the water inlet to the chiller unit,
disconnect and insert into the ‘feed
in’ port on the Pureh2o3 sterilisation
system.
3. Connect the outlet of the Pureh2o3
system back into the chiller.
To sterilize the internal pipe work.
1. Activate the chilled water flow at the
tap.
2. Apply power to the Pureh2o3 system.
3. Allow chilled water to flow for 30
seconds.
4. Stop the chilled water flow.
5. Immediately disconnect the power to
the Pureh2o3 system.
6. Wait for 5 minutes then repeat the
process.
The O3 (ozone) emitted in this procedure
will effectively sterilise the internal pipe
work without the need for chemicals.
Recommission the Unit
Reverse steps 1 – 3, and allow the unit to
complete a cooling cycle.

Prior to any fault finding, please ensure all
water connections to the chiller are sound
and that the incoming water is turned on.
Also ensure that all electrical connections
to the chiller and in the chiller are secure
and in good condition, and that the
power is on.
If the above are satisfied, ensure that the
chiller has had adequate time to reach
operating temperature.

REMOVAL, TRANSPORTATION & DISPOSAL
————————————————————
Important: Before removal from the
installation, ensure all electrical,
product and gas connections are
disconnected.
DISPOSAL OF SCRAP UNITS
It is illegal to simply scrap a refrigeration
unit. Before a unit can be scrapped
it must first have the gas removed by
a specialist using special equipment.
Please contact Pure H2O, who will be
happy to provide a quotation for disposal.
TRANSPORTATION
Important: This unit must be transported
in an upright position.
As with all refrigeration systems, irreparable
damage can be caused by laying the
unit on its side or even transporting upside
down. Where the unit is transported by
a carrier, the carton should always be
marked in a conspicuous manner, the
correct upright position in which it must be
handled.
If a unit has been transported incorrectly
it should be placed in the correct upright
position and left for 24 hours before
attempting to run the system.
Failure to observe the above precautions
could seriously damage the system, and
would void any warranty.
