Range Overview
A comprehensive range of watercoolers, available in two different operational types:
• “Classic”- Reservoir Model
(Cold Water Storage Tank)
• “Direct Chill” Model
(No Stored Drinking Water)
Both types are available as:
• Floorstanding
• Countertop
All Reservoir models are available as either
• Cold and Ambient
• Hot and Cold
Direct Chill models are currently only available as Cold and Ambient.
4
628 & 698 Models
All types
All b & o “Classic” & “Direct Chill” models are self contained machines with robust steel sided cabinets and
attractively moulded front and top panels.
An IEC Power Lead is supplied for connection to the IEC socket found on the rear of all models.
Floorstanding Models
All are supplied with an opening lower door and are prefitted with a removable filter mounting bracket. A water
inlet fitting is provided to the bottom right hand corner.
(Adjustable feet will be standard from 2009).
Countertop Models
A void is provided with the front panel area to accommodate most filter types where external installation in an under
cabinet is not possible.
“Classic” Reservoir Model:
Water is fed into the reservoir via the Float Valve mounted in the Tank Lid. The Float Valve controls the water level in
the tank. Ensure a Pressure Reducing Valve is fitted to all supplies greater than 3.5 bar pressure.
The Baffle Plate inside the Cold Tank maintains separation between the lower chilled water and upper ambient
water. (The cooling system only chills water in the lower part of the Cold Tank).
Dispense is at gravity pressure only via push operated Taps.
The Cold Temperature is thermostatically controlled via the adjustment screw on the back of the machine. This is
factory set and is not necessary to adjust in most cases. (See Controls)
On Hot & Cold versions, the Hot Tank is fed with ambient temperature water from the upper area of the Cold Tank.
The Hot Temperature is thermostatically controlled with sensors on the outside of the Hot Tank. These are preset
and are not adjustable. The system is designed so that the Hot Tank is impossible to run dry under normal usage.
Running dry can only occur if the inlet water is drained using the Drainage Point provided. In the event of running
dry the Overheat sensor would switch off the heater until manually reset.

Installation and Operational Guide
IMPORTANT - the guide must be read before attempting to connect the machine.
Introduction
Congratulations on your wise choice of water cooler. Your Borg & Overström water cooler will provide you with a
continuous supply of water 24 hours a day. To ensure that his product will always perform as it truly should, the
user should initially read this manual thoroughly and follow all the instructions before operation of the unit
commences.
Installation
The water connection to the Borg & Overström water cooler is via a 1/4” supply. The connection can either be made
utilising the bulk head connector found at the rear of the machine or by connecting an in-line straight connector
direct to the pipe inside the rear of the machine. It is advisable that in any case an in-line isolation tap should be
installed on the supply just behind the machine in case of emergency.
Operation Method
1. Having connected the water supply to the rear of the machine, the water supply should be turned on and you will
hear the reservoir within the machine start to fill. Once this has stopped filling, the entire tank should then be
drained and allowed to refill before operation of the machine commences. If in any doubt at this stage please add
some sanitisation fluid to your initial tank of water so as to flush the machine before use. Once the machine has
refilled with water the machine can be connected to the mains supply and switched on.The switch at the rear of the
machine then needs to be turned on before operation can commence.
NB. If your water cooler has a hot water facility please allow time for the hot tank to fill up before turning on. To
draw water into the hot tank, the hot tap must be held open until water starts to dispense.
2. Both LEDs on the display panel should now be showing. After initial chilling operation has been completed the
chilling lens will go off, which is the bottom of the two lenses showing.
Machine Positioning
1. It is important that at least 10cm is left between the back of the machine and the surface against which it is
placed. This is to ensure that the machine does not in any way overheat.
2. The machine must be kept away from any direct sunlight.
3. It is important that the machine is connected to an RCD connected supply making doubly sure that the voltage
supply is compatible with the machine.

Sanitisation & Cleaning
1. Please make sure that the machine has been disconnected from the electrical supply before any cleaning
commences.
2. The lid of the machine should be removed exposing the inside of the water tank. Now press both the cold tap and
the ambient tap to drain all the water from the reservoir until no water can be seen. Remove the baffle plate found
in the centre of the tank passing it around the float valve to remove it completely. At this stage it is possible to see
whether any water has been left in the base of the tank. A hundred miliilitres of sanitising fluid can now be tipped
into the reservoir.
3. The water can be turned on again briefly to half fill the reservoir with sanitising fluid. The upper half of the
reservoir should be cleaned utilising sanitisation wipes supplied by Azure. Whilst the sanitisation fluid is having its
effect, please clean the external casing with Azure sanitisation wipes. Once the sanitisation fluid has been left for a
satisfactory period of time, please flush the water cooler through at least once by turning the water back on. When
this has been completed, the machine can be reassembled and your sanitisation is complete. Please now switch
the power back on. If you have any question regarding sanitisation please do not hesitate to ring Azure Head Office
on 0845 4 50 30 90.

LEAK DETECTOR
Installation and Operational Guide
IMPORTANT - the guide must be read before attempting to connect the machine.
Introduction
Congratulations, you have chosen wisely to add a
Leak Detector to your Borg & Overström water
cooler. This product does not in anyway provide a
guarantee or insurance against any flooding but
provides the means of added prevention. Please
ensure that you read this manual thoroughly before
proceeding, and take note of the installation and
operation procedures to achieve the best results.

628 & 698 Models
Installation & Operation
This product can only be used in conjunction with a Borg & Overström water
cooler.
Please follow the step-by-step procedures for installation:
1. Please fix the Leak Detector as high as possible within the machine.
Ensure that the red lever has sufficient space to be activated. It is
imperative that the electrical connections are facing upwards and the
water pipe is installed into the base of the Leak Controller and that the
Leak Controller is mounted vertically.
2. The detection probes can now be fixed into their locating holes in the
channel within the base plate.
3. The inlet and outlet connection ports for the water are connected via 1/4”
push fit fittings. The pipe already located within the machine must be
connected to the outport on the machine and the supply feed coming into
the machine must therefore be placed into the inport. Find a connection
plug within the back of the machine where the power supply comes in.
Please part the two sections of this connection plug and plug your Leak
Controller into these two connections. Note: This will only work one way
round (you cannot get it wrong).
4. Your Leak Detector is now ready for operation. Please ensure that the
red lever is in the closed position before plugging in your Borg &
Overström water cooler to the mains supply.
RESETTING DETECTOR
In the unlikely event of a leak from a Borg & Overström machine the water detector will automatically shut off both
the power and incoming water supply. Please follow the following procedures to reset the detector to regain normal
operation.
LEAKS & REPAIRS
1. Unplug the machine from the electrical supply. Intially the machine must be left unplugged whilst the repair is
being carried out.
2. Identify the cause of the leak and replace any necessary parts. Once this has been carried out thoroughly dry out
the channel in the base of the cooler. The probes should then be removed from their locating positions,
thoroughly dried and placed back into position.
3. Now push the red lever back into its normal position so as to return to operation. The power can now be
switched back on to the cooler and the machine is ready for operation.
4. In the unlikely event that the red lever should trigger once more, then procedures 1 to 3 should be carried out again.
5. Please note that the electical power to the machine, not just within the machine, must be disconnected for at
least 5 seconds to enable the device to reset. A shorter on-off-on cycle time is unlikely to be long enough, and
the machine on/off switch will not cut the power to the device.
In the event of any queries please call Technical Support on 0845 4 50 30 90.

Sanitisation Guide
Direct Chill Water Coolers
Turn off incoming mains water, briefly press dispense button(s) to release internal water pressure from the
machine and remove filter. If possible temporarily shut off inlet to any hot tank as sanitisation of a hot tank in
continuous use is unnecessary.
Add 100 ml of a proprietary sanitisation fluid to a clean and empty service filter cartridge/dosing device and connect
into machine. Always ensure to use a reputable branded sanitisation fluid for effective action.
Please note: We recommend using a 3% Hydrogen Peroxide concentration base sanitising fluid of reputable
manufacture to the appropriate dilution ratios as supplied with the product or typically 1:30 max. (Stronger
concentrations will require larger dilution rates).
Please remember that most sanitisation fluids (including ozone) contain an active caustic/alkaline agent. Always
use responsibly and with care remembering that due to its alkaline nature unnecessary concentrated/prolonged
contact with any materials, including metals, can cause damage. Always rinse all contact surfaces after use with
clean water.
Turn on incoming water, allow service cartridge/doser to fill and then draw off at least 1 litre of water for the
machine to ingest the solution. Leave solution for 10 minutes inside machine for sanitisation to take effect. During
this time thoroughly clean the machine externally. For this we recommend the use of proprietary disposable
sanitisation wipes. Pay particular attention to the dispense faucet and the push button controls. Remember to
include the drip tray. If a Waste Overflow System is fitted, this may benefit from flushing through with a small
amount of dilute sanitisation fluid. Optionally you may replace the dispense faucet and/or descale it.
After a satisfactory period of time, flush the machine with at least 10 litres of clean water to clear any trace of the
sanitisation fluid. Optionally use test strips to check.
Turn off water and remove the service filter/doser and fit a new filter of reputable quality and suited to the site
conditions. We recommend pre-flushing the new filter to reduce any risk of any loose media in the filter entering
the solenoid valves and possibly causing a malfunction. Retain the service cartridge/doser for reuse.
Turn on incoming water supply and carefully ensure the thorough sanitising of the outside of the machine is
completed. Reconnect power and reset any service/filter life monitors accordingly. Ensure any hot tank inlet is
reconnected and the tank is purged of air before switching heater on again.
ALWAYS ENSURE ANY RESIDUAL AIR HAS BEEN PURGED FROM BOTH
COLD AND HOT SYSTEMS AND ALL IS OPERATIONAL BEFORE LEAVING.

Sanitisation Guide
Reservoir Water Coolers
Please make sure that the machine has both been switched off and disconnected from the electrical supply and
that the water is turned off, use the taps (and drain point if fitted) to drain off all the water, before any cleaning
commences.
The lid of both the machine and the tank should be removed exposing the inside of the water tank. Remove the
baffle plate found in the centre of the tank. Any lime scale or mineral deposits should first be removed by manual
scrubbing with a non-metallic sponge-scouring pad. For stubborn deposits, most domestic brand stainless steel
cleaners can also be used.
If your machine is a Hot & Cold machine please ensure that the inlet to the hot tank is closed off sufficiently to
prevent sanitisation fluid entering the hot system.
If using a service dosing cartridge, please now go straight to no 4. At this stage it is possible to see whether any
water has been left in the base of the tank, 100ml of sanitising fluid can now be tipped into the reservoir. (We
recommend a hydrogen peroxide base sanitising fluid of reputable manufacture using the dilution ratios as
supplied with the product.)
Remove the existing filter and install a filter head to suit the service cartridge if necessary. Empty 100ml of
sanitisation fluid into the service cartridge and connect the cartridge to the filter head.
The water can be turned on again briefly to half fill the reservoir, forming a sanitising solution. The upper half of the
reservoir should be cleaned with sanitisation wipes. Leave for 10 minutes to effect sanitisation, whilst the
sanitisation solution is having its effect, please fully clean the external casing with sanitisation wipes, ensuring
particular attention is paid to the faucets. Once the sanitisation fluid has been left for a satisfactory period of time
please flush the water cooler through at least once with clean water.
When this has been completed, the machine can be reassembled and your sanitisation is complete. Always
remember to replace the filter(s) with the appropriate type(s). (Retain service/dosing cartridges for reuse.) Please
now switch the power back on.
Ozonation is another alternative, but not a recommended method, as we believe the opportunity should always be
taken to inspect the machine internally, remove any scale or mineral build-ups and take interventive action where
appropriate.
ALWAYS PURGE AIR FROM THE COLD AND HOT SYSTEM BEFORE
SWITCHING POWER ON AGAIN.

628 & 698 Models
Descaling Guide
Reservoir Model
Scale deposits will occur whenever water is heated. Higher deposits will occur with harder water and higher
temperatures. Although scale deposits can be reduced through using softened water this is not necessarily
desirable due to the adverse effect on taste. Therefore, it is important that descaling is carried out regularly to
maintain the high efficiency of operation of your appliance.
The frequency of descaling depends on the hardness of the water and the intensity of usage in each case. At least
every 12 months is highly recommended. Although it is primarily the Hot Tank (Water Heater) that requires
descaling, it is also necessary to sometimes carry out some in the cold tank.
Please note: Descaling is to remove the inevitable build up of limescale and should not be
confused with sanitisation, which is a different procedure for maintaining the necessary
hygiene standards for drinking water.
1. Switch off the power and water supply. Drain off water, including Hot Tank. It may be beneficial at this stage to
flush through the hot tank with clean water to remove as much loose scale as possible if the tank appears
particularly scaled up.
2. Carefully fill a suitable pouring jug with approx 2 ½ litres of hot water and add the correct amount of descaler
relevant to the enclosed instructions for safe and effective use.
3. Remove the Top Cover from the appliance (and the lid covering the cold tank on later models).
Carefully remove the Float Valve and Baffle Plate from the Cold Tank.
4. Slowly pour the descaling solution into the Cold Tank. This will drain directly into the Hot Tank. Continue to add
the solution until it also just begins to fill the Cold Tank too. Leave the solution to react with the limescale as
directed.
5. Should limescale be present in Cold Tank, carefully treat the areas concerned using the same solution. Also,
treat any removed parts such as the Float Valve, after checking the directions for use for compatibility. Similarly,
if the outlet taps need treatment, dispense a little solution to draw it into the taps. Examine the small black
rubber water stop seal on the Float Valve for any damage or wear and replace if necessary. DO NOT ROTATE
THE SEAL IF IT IS NOT BEING REPLACED AS THIS COULD AFFECT ITS WATER SEAL SEATING AND ALLOW
SEEPAGE.
6. After an appropriate time, carefully scrub any surface scale to remove it taking care not to damage the part. If
scrubbing of the inside of the taps is required, remove the Front Panel of the appliance and carefully dismantle
the taps by unscrewing the ring under the lever and then drawing the lever mechanism upwards out of the body.
N.B. Before removing the taps, drain off any remaining solution in the cold tank.
7. Reassemble any removed parts as necessary and flush appliance through thoroughly with mains water as
directed (Carry out sanitisation procedure at this point if desired).
8. Finally, allow appliance to refill, check for any leaks and switch on power supply.

Tools Required
10-Ltr Bucket
1Litre jug
*1Pt Long Blade Phillips Screwdriver (250mm blade min)
Flat Blade Screwdriver
Side Cutters
Estimated time 20 minutes
*Preferable, otherwise a standard short bladed version can be used.
1. Switch off the two switches on back of the machine and disconnect the power lead. Isolate the mains water
supply.
2. Fully drain all the water from the machine. The cold water can be drained via the Cold Tap and the hot water via
both the Hot Tap and the Hot Tank drain. CAUTION-THE WATER MAY BE VERY HOT. If the tank is heavily scaled
the drain may be partially or fully blocked requiring more caution. On the Floorstanding machine, the drain is on
the back of the machine and on the Countertop, it is underneath.
3. Remove the two screws at the back of the top Panel and lift off.
4. Carefully remove Tap Cover Panel (as shown by first
squeezing inwards and then out),and disconnect PCB
5. Remove the two screws at the top of the front panel and in the
case of a Floorstanding machine, open the Door Panel and
slacken off the two screws at the bottom. (You may if you prefer,
remove these completely). Remove the front panel by lifting it
upwards slightly first, then away keeping it clear of the taps.
With a Floorstanding machine, the Door Panel will then need
lifting off its lower hinge pin and setting aside.
N.B. Be careful to avoid damaging the high quality finish to the
panels whilst these are removed from the machine.

Azure Technical Advice
Procedure For Checking the Compressor/ Cooling Operation
If the Compressor does not run:
1. Check the LED display
For Cold & Ambient models the green (top) LED should always be on and the Yellow (Bottom) when cooling is
called for. If the green is off then check the machines main power supply and the on/off switch.
For the Hot & Cold models the green (top) LED should always be on. If off, check the machines main power
supply and the COLD on/off switch.
2. Switching on the Compressor measure the current draw. No operation, but a high draw indicates a jammed
compressor (contact Azure Technical Support).
3. The wiring loom can be traced and the live supply check periodically moving towards the compressor (if there is
a break at the Cold Thermostat turn the screw clockwise and check whether this closes the circuit. If this
doesn’t even when at max, the thermostat should be replaced. Alternatively, for testing purposes only, the
thermostat could be bridged).
4. Remove the compressor relay cover and carefully remove the relays. If the power has been even recently
connected to the compressor, the solid stat relay will be energised and will need discharging.
5. Check the Compressor resistance readings.
R
S
C
Approx readings could be:
R-C 12ohms
S-C 34ohms
R-S 46 Ohms (sum of both)
N.B. There should always be some variation between compressors. What should be identified is large
discrepancies/unbalanced readings.
Also, especially in the case of large discrepancies/unbalanced readings, check for continuity between any of the
terminals and the compressor casing. A current will indicate a shorted winding (Contact Azure Technical
support).
6. Checking the relays:
Caution: Ensure the larger relay is discharged if recently energised. (This can be discharged by 2MR, 2W resister
in the circuit).
Clearly, the best and surest way to test the relays is to replace them one by one and check the compressor
operation. Otherwise, each relay component can be basically tested using a meter
The Solid State Relay should read approx
3-6 closed circuit
3 ≈ 36 Ω (Ohms)
The Klichson (overload) should read approx
≈ 1.7Ω (Ohms)
7. Ensure the terminals are clean and good contact is made.
72
628 & 698 Models
If the Compressor Does Run
(Presuming that the Cold water is not being cooled sufficiently)
1. Check the small pipe on the ‘high’ side of the compressor. This should be quite warm after several minutes of
normal operation.
2. Following it to the condenser, check the condenser temperature. Normally the beginning will be warmer,
cooling off towards the end.
• No or very low temperature could indicate a low refrigerant charge. A low current draw would indicate this.
(Contact Azure Technical Support).
• An overly high temperature could indicate a blockage; A high current draw would confirm this. (Contact
Azure Technical Support).
3. Continue to follow the pipe work from the end of the condenser to the dryer.
• A frozen / iced dryer will indicate a blockage (Contact Azure Technical Support) Again; a high current draw
would confirm this.
4. The dryer exits into the capillary tube. Check this for restrictions and NB: This has a very small bore.
5. The Capillary enters the evaporator. This can be checked visually for any obvious signs of deterioration.
6. The evaporator connects back to the ‘low’ side of the Compressor via the suction pipes.
Check this for excessive icing.
Excessive icing could indicate a refrigerant overcharge (Contact Azure Technical Support).
