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.

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
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.
IMPORTANT - the guide must be read before attempting to connect 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.

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

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.
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.

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.
