SAFETY NOTICES
For your safety, we draw your attention to the following warning and caution marks throughout the manual; the
safe operation of an ATC chiller always remains the responsibility of the operator. This equipment is intended to
be used as a liquid temperature conditioning device –it requires no external pump, nor any further manipulation
of temperature. If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
Caution; Failure to comply with a caution will invalidate product warranty and absolve ATC from any
liability, howsoever caused, and could result in permanent damage to equipment.
Caution; Filling/topping up of the tank should only be undertaken with the unit switched off, to prevent
back-filling of the fluid.
Caution; The high integrity refrigeration system contains no user-serviceable parts. Repair and service
requires specialized knowledge and tools to be provided by ATC or its local agent. Any unauthorized
tampering with the refrigeration system automatically invalidates warranty.
Warning; Very cold surfaces and gases, lower than -20°C (-40°F). Severe frostbite hazard.
Warning; Opening the refrigeration system may expose the operator to toxic and corrosive compounds
(HFCs). Take protective measures including suitable eye protection.
Warning; Gases may exceed 15 barg (220psig) during operation.
Warning; Refrigerant is class A1. It does not support combustion but is oxygen depleting. Review
equipment rating label for specific refrigerants and CO2e.
Warning; Water and electricity are in close proximity. Always ensure the unit is isolated before service.
The R-series is protected from overcurrent by mains fusing. Never bypass these components.
Warning; Failure to comply with a ‘warning’ may result in personal injury or death. ATC does not accept
any liability for injury caused through use of this equipment.
Warning; After switching off, the fan blades slow to a stop. Do not open until the fan has stopped
rotating.

UNPACKING UNITS WEIGHING OVER 18kg (40lbs) WITHOUT CASTORS
1
Please check that both the packaging and the unit are undamaged. If there is any doubt, it is vital that you
inform both ATC and the carrier. There are no hidden shipping bolts or other fixings. You should inspect the
packaging for signs of transit damage before signing for the unit, and if possible, unpack the unit before
signing. Once you have signed for the goods, ATC cannot be held responsible for any transit damage
subsequently found.
2
As the unit is >18kg, ATC must recommend that 2 persons are used to lift by hand, or a crane.
3
Remove the unit from its original packaging and ensure that there is no packaging left around the cooling
ducts. There is no internal product packaging that requires the chiller to be opened.
4
Please retain all packaging in the unlikely event that the chiller needs to be returned to our local
representatives.

R10 & R20 SITE & ENVIRONMENTAL REQUIREMENTS
1
Rack mount –this product is only intended to be used with a ventilated standard 19”rack cabinet. R10 is a
6U high unit and R20 is an 8U high unit. Both units are 560mm deep. Both units require 4-off end user-
supplied M6 bolts to secure to rack cabinet upright rails. ATC strongly recommends the use of support guides
that run from the front upright rail to the back upright rail of the rack cabinet to support the weight of the
chiller.
2
Clean, dust-free environment –the R10 & R20 units use external axial frame fans to provide airflow for
cooling the pump motor, compressor and condenser. Do not block these vents. The system will shut down in
the event the motor high temperature or refrigeration system high pressure switches are triggered.
3
Non-condensing ambient temperature –+5°C to +40°C (+39°F to +104°F). This prevents build-up of
moisture on internal components.
4
Humidity - 80% for ambient temperatures up to +31°C (+88°F), decreasing linearly to 50% relative humidity
at +40°C (+104°F) ambient temperature.

The power inlet module itself is rated 10A 250V. The user must provide protective earth at IEC type C14
appliance inlet. See product rating label for fuse specification. Mains fuses are typically UL-compliant and T
speed rated with high breaking (rupture) capacity. Supply fuses are rear mounted. Secondary fuses
protecting individual components are internally-mounted.
6
Clearance –the rack form factor limits clearance considerations to the rear face of the unit. Ensure there is
sufficient room at the rear of the product to remove the power cable without obstruction. Ensure bend radius
of your chosen hose/tube/pipework is not compromised. The front face of the R10 has no vents, but the R20
does –it is a suction vent. Left and right-hand side clearance is dictated by the rack cabinet, but both R10 &
R20 have suction vents on those faces.
7
Plumbing –tubing, piping or hose must be clean and compatible with the fluid to be used. The chiller is
compatible with deionized water and water-glycol mixtures such as Hexid fluid.
8
Indoor use only –altitude up to 2000m.
9
Installation category –transient overvoltage category II; Pollution degree 2. Temporary overvoltages
occurring on mains supply are acceptable within limits defined in the aforementioned categories.
Caution; Always use ATC recommended fluids in your chiller –many other anti-freeze mixtures have the
potential to corrode your application and to damage seals in the chiller.

INSTALLATION FOR WATER-COOLED UNITS WITH 1/2" BSPPF FITTINGS
This guide applies to the following product groups;
-K-Series, R-Series and G-Series refrigerated units, where heatload is carried away by water supply.
-XR- and XF-Series water-to-water heat exchangers, where heatload is carried away by water supply.
HOSE RECOMMENDATIONS
Having ensured that your installation meets all site requirements, it is best practice that the fluid lines between
your application and the chiller have the following characteristics.
1
Short in length –this reduces friction-based pressure drop and addition ambient heat load.
2
Large diameter bore –at least 12mm (1/2”).
3
Free from 90° bends –to limit the effects of water hammer. If this cannot be avoided, sharp changes of
direction should be minimized so far as possible. Doing this correctly can yield higher pump performance
and extend time between maintenance intervals. It will also reduce electrical energy consumption.
4
Clean –If your installation is to existing pipe work, it is good practice to flush the system with either a
commercially available central heating cleaner or 5% acetic acid solution. The system should be flushed
clean with tap water to remove all traces of cleaner prior to filling the system. Failing this, it is recommended
to use a domestic bleach in solution with tap water, diluted to the point where the bleach can longer be
smelled by human nose.
5
Opaque, ideally black –to inhibit light passing through the tube and algae building up. Alternatively, solid
ABS or copper pipe can be used where application chemistry allows.
6
Insulation, where low temperature process is planned –the process line from chiller to application
contains the feed of low temperature fluid. Insulation prevents heat from entering this line and can promote
better stability. Uninsulated return lines are helpful where free cooling can be obtained by allowing heat to
transfer to air –likewise, insulating the return line is helpful if the fluid temperature is below ambient.
Caution; Never use transparent tubing. UV light will pass through, prompting growth of organic
contamination.
CONNECTING ADPATERS TO PRODUCT BULKHEAD FITTINGS
1
Standard units are supplied with 1/2” British Standard Pipe Parallel Female (BSPPF) threads (also known
as G threads (ISO228)) by default, for both application/process and house/primary water supply. These
fittings are not valved and will ‘drop’ the volume of the system if left open to atmosphere.
2
Ensure the appropriate thread sealants are used in the fitting of adapters to hose. For metallic mating parts,
we recommend Loctite 577. For plastic adaptors such as those supplied with the product, we recommend
using ~8-12mm wide PTFE tape, wrapped around the male thread before tightening.
3
Ensure that the system is correctly connected. The ‘donut’ labels around the ports are clearly marked with
inlet and outlet symbols and function in both English and French language. Ports marked as outlets mean
fluid leaves the product and must be connected to the process inlet or house water return line.
4
Check all joints are tight and leak free.
5
Where this product is incorporated into other equipment, it is the responsibility of the assembler to ensure
safety.

BACKFILLING
1
In situations where the chiller is situated physically lower than the application being cooled, fluid will apply
pressure to the water circuit of the product.
2
The weakest seal is normally the tank lid, and this is typically where fluid will escape the unit.
3
Ideally, the product will be located higher or level with the product water-line. If this is not possible, a non-
return solenoid valve kit can be installed as an optional standard assembly.
4
Please raise any questions with the sales team on [email protected]m.

FILLING A SYSTEM
a) Check all application valves are open, including solenoid valves and variable position valves.
i) The product will require an open water circuit to pump into.
ii) Any obstructions can increase the time, or entirely prevent the bleeding of air from the system.
b) Remove the cap from the tank lid on the top of the product.
i) Fill the tank to just underneath the bottom of the filling port.
c) Turn your attention to the main power switch.
i) Immediately after toggling this switch assuming that the power cord is connected and turned on at the
wall the product will begin to pump water.
ii) Leave the product to run until it cuts out on the level switch interlock.
iii) Turn the unit off at the mains switch.
iv) Fill the tank again to lift the level switches.
v) Start the product again until the unit cuts out again.
Caution; Do not run the pump dry. Do not deadhead the pump.
d) Repeat steps at c) until the chiller tank water level (if visible) doesn’t drop, and the chiller doesn’t cut-
out on its level switches.
e) With the unit now running;
i) Leave the cap off the tank for >30mins to allow air to escape, or very loosely screwed on to prevent
water splashing out of the tank if the unit has a ‘flow through’ design.
f) Check the application and tubing for signs of leaks whilst the chiller is running.
i) Replace the tank lid fully when satisfied the system is full and bled of air.
DRAINING A SYSTEM
a) Isolate the unit. Have a suitable bucket or drain on-hand.
i) Remove the tank lid to allow air into the system.
ii) Disconnect hoses individually. Be aware hoses as well as the unit are filled with fluid.
iii) Consider using the red transport plugs to block product ports to give yourself time to empty hoses before
continuing to empty the product.
b) Local rules affect where fluid can be disposed of.
i) Ensure hazardous products do not enter the water course and are reclaimed from the unit for professional
disposal.

BASIC PROGRAMMING GUIDE KR1 (ALL MODELS)
This guide may apply to your product if you require general navigation advice and help accessing settings. If you
are planning to change the settings in any way, you may need a copy of the existing settings which are model
dependent, signified by a letter on the end of Annex E-15, i.e. Annex E-15A.
DISPLAY CONTENTS DURING NORMAL OPERATION
1
Physical navigation buttons, up, down, return and enter.
2
8888.8 is the actual read value on input sensor.
3
888.8 is the setpoint value.
4
Rectangles bottom left 1-4 display when output is active.
5
MAN LED shows in manual mode (fixed output value).
6
°C or °F shows units as settable in the ‘inP’ group.
7
AL LED appears when output is beyond a set alarm point.
ACCESS TO SETTINGS
8
Push the return button for more than 5 seconds. The upper display will show PASS while the lower display
will show 0.
9
Using up and down buttons set the programmed password –full access is granted by entering ‘40’. ATC are
not responsible for damage either to the chiller or the connected equipment as a result of changing
parameters without ATC’s oversight.
10
During parameter modification the instrument continues to perform process control. In certain conditions,
when a configuration change can produce a significant change to the process, it is advisable to temporarily
stop the controller from controlling during the programming procedure (control outputs will be OFF).
A password equal to 2000 + the programmed value (i.e. 2000 + 40 = 2040). The control will restart
automatically when the configuration procedure will be manually closed.
11
Push the return button. If the password is correct the display will show the acronym of the first parameter
group ‘inP’. Push button for more than 5 seconds, the instrument will come back to the “standard display”.
12
The configuration parameters are collected in various groups. Every group defines all parameters related
with a specific function (control, alarms, output functions).
13
Push return button for more than 5 seconds, the instrument will come back to the “standard display”. For
specific settings and guidance, review the controller datasheets provided by ATC. If you are not in receipt of
these, please contact ATC using the information in the header of this document.
GENERAL NAVIGATION
14
Return button; A short press allows to exit from the current parameter group and select a new parameter
group. A long press allows you to close the configuration parameter procedure (the instrument will come
back to the “standard display”).
15
Enter button; When the upper display is showing a group and the lower display is blank, this key allows to
enter in the selected group. When the upper display is showing a parameter and the lower display is
showing its value, this key allows to store the selected value for the current parameter and access the next
parameter within the same group.
16
Up button; Allows to increase the value of the selected parameter.
17
Down button; Allows to decrease the value of the selected parameter.
18
Pushing both Return and Enter buttons moves back to the previous group. Press return first to start. The
selection of the group is cyclic (on a carousel), so it is possible to move back around to the group you
require.

POSITIVE DISPLACEMENT PUMPS & DISCRETE PRESSURE RELIEF VALVE
This arrangement comprises a positive displacement pump (most commonly a rotary vane type) with a spring-
loaded pressure relief valve to provide better overpressure setting control with minimal flow losses compared to
fixed orifice bypasses/reliefs. This annex describes ATC’s default settings and how to adjust the system.
It is important to understand the basic principle that all else being equal, higher flow results in a higher demand
for pressure. The motor generates the power required to turn the pump head and create that pressure. The more
restrictive a water circuit is, the higher the pressure required to maintain flowrate. Positive displacement pumps
are designed to generate high pressure and are mechanically tight - their RPM dictates flowrate. See image;
1) Pump discharge –fluid leaves the pump head and enters the gauge-tee assembly. It passes the
temperature sensor at the tee, and when the pressure relief is inactive, fluid heads towards no. 2.
2) Outlet to process –fluid heads out of the product to the application. Whatever restrictions lie
downstream, fluid leaving this point has not passed through the pressure relief valve.
3) Pressure gauge connection –connection to a pressure gauge on the front panel of the product. This
displays the pressure in the water circuit, at the pump outlet, not the application which will be lower.
4) Pressure Relief Valve (PRV) –spring tension in the body of the PRV determines whether fluid travels
through point 2 or passes through to point 7.
5) PRV adjustment knob –rotate clockwise to increase maximum delivery pressure. Rotate anti-clockwise
to limit maximum delivery pressure.
6) PRV adjustment locknut –release this locknut to adjust no.5. Ensure it is tightened once adjustments
are made. If it is not, vibration may cause the adjustment knob to move on itself.
7) Bypass flow outlet –where the pressure requirement to overcome restrictions downstream of no.2 rises
to be higher than the setting at no.5, the spring inside no.4 will compress and allow liquid to start bleeding
through to no.7. It is important to understand that the nature of the spring means there can be no black
and white point for pressure relief setting –the spring will slowly compress and bleed flow until all flow
passes through no.7. When fully bypassing, all flow stays inside the chiller to protect the application.

SETTING THE PRESSURE RELIEF VALVE (BYPASS)
Unless otherwise agreed at point of sale, the default setting for this type of pump and PRV arrangement is
3.33bar (50psi). In the absence of external calibrated pressure gauges, it’s possible to use the chiller itself to set
this value;
8) Isolate the chiller –always isolate before performing work.
9) Disconnect from the application if already connected –review the draining procedure in Annex D.
10)Connect the chiller’s process inlet to process outlet –a short run of hose around 1-2m (3-6ft) will be
adequate.
11)Start the chiller and follow the fill process from Annex D –fluid will now be running through a short
loop with very low pressure required to overcome the restriction.
12)With the chiller running, very slowly kink the short run of hose fitted above –this simulates a
blocked application –this is known as ‘deadheading’the pump. Without PRV, the pump motor would stall
or hoses might blow off. Watch the pressure gauge climb as you apply the kink.
13)The pressure gauge will eventually stop climbing with the hose fully kinked –note the value; this is
the setting of the PRV where all flow is bypassed.
14)Refer to points 5) and 6) above to adjust if required –contact ATC if you’re unsure over whether your
desired setting is reasonable for the product you have.

AIR-COOLED K-, G-, R-SERIES INITIAL TROUBLESHOOTING
#
SYMPTOM
CAUSES
1
Compressor or
pump motor not
running
Large condenser
fan is running, and
control illuminated.
Level switch may have been tripped –check level and top-up to resolve.
High pressure switch may have been tripped;
a) Check fan spins freely and that condenser is clear of debris.
b) Assess whether the ambient temperature is too high.
c) Assess whether ventilation/air circulation is poor.
d) Assess whether surrounding equipment is generating hot air and feeding it into
the chiller air intakes.
If fitted, a low-pressure switch may have been tripped –this indicates refrigerant loss.
A multimeter is required to test this.
If running at a high setpoint, or if operating conditions have changed and raised the
fluid temperature, it is possible the compressor has turned itself on high temperature
internal protection.
2
Noisy operation
Pump motor or fan motor bearings may have failed.
Pump head vane or seal may have failed.
In a 3-phase system, phase rotation may be incorrect.
3
High fluid pressure
/ low flowrate
Fluid lines may have become fouled through solid debris or biological growth.
Ensure biocides or pre-mixed biocidal process fluids are being used.
Ensure hoses are not transparent or translucent –UV light entering prompts growth.
General fluid leak can lead to flow rate failure.
Excess fittings, too many sharp direction changes, too small a diameter hose for
flowrate or hoses too long at the wrong diameter.
4
Fluid collecting or
leaking
Leaks are impossible to diagnose remotely, but usually you will see a pool of fluid on
a lower surface. Do not confuse this with condensation from cold parts of the fridge.
Review the chemical compatibility of your fluid with the chiller. Contact ATC if you are
unsure.
5
Poor cooling
performance
Check fan spins freely and that condenser is clear of debris.
Excess thermal load applied.
Assess whether the ambient temperature is too high.
Assess whether ventilation/air circulation is poor.
Assess whether surrounding equipment is generating hot air and feeding it into the
chiller air intakes.

SYMPTOM
CAUSES
1
Compressor or

illuminated.
Level switch may have been tripped –check level and top-up to resolve.
High pressure switch may have been tripped;
a) Check for sufficient flowrate and pressure of house water.
b) Assess whether the house water temperature is too high.
c) Assess whether any fouling of condenser plate heat exchanger has occurred.
d) Assess whether new equipment has been added to a shared water supply and
contributed to either a lack of water flow (through flow splitting) or whether
additional thermal load has been added to the central water’s chiller/cooler.
If fitted, a low-pressure switch may have been tripped –this indicates refrigerant loss.
A multimeter is required to test this.
If running at a high setpoint, or if operating conditions have changed and raised the
