A range of compact water dispensers, available as a Reservoir (gravity fed) system and a Direct Chill system:

• Reservoir Chilled & Ambient
• Reservoir Chilled & Hot
• Direct Chill Chilled & Ambient
• Direct Chill Chilled & Hot
• Direct Chill Chilled, Ambient & Hot
• Direct Chill Chilled, Hot & Sparkling
• Direct Chill Chilled, Ambient & Sparkling

The b3 model is available as countertop and floor standing in three colours.

All Models
All models are self-contained machines with robust steel chassis and attractively injection moulded plastic front and top panels. For floorstanding models there is sufficient space internally for most filters.
For countertop models any filters would need to be fitted externally. An IEC Power Lead is supplied for
connection to the IEC socket found on the rear of all models (An additional Schuko type is supplied for the European market).

Chilled
Water is fed into the insulated cold tank under mains pressure. We strongly recommend a Pressure Reducing Valve is fitted to all supplies to regulate the
pressure to 3.5 bar/355 KPat. The cold tank is chilled via the evaporation coil of the capillary controlled refrigeration compression system. The cold temperature is thermostatically controlled via the
adjustment screw on the cold thermostat. This is factory set and is not necessary to adjust in most cases (see Controls).

Ambient
Water bypasses the cold tank for the
ambient dispense.

Sparkling
Water is chilled as it passes through the coil immediately before dispense or being pumped under pressure into the carbonator which it fitted inside the same coil. The carbonator is also level controlled and
allows the sparkling effect to occur through saturation with CO2.

Hot
Hot water is provided by a hot water tank with an external heating element. Water is supplied directly into the tank under gravity fed pressure, and when full hot water is dispensed by displacement. On
sparkling models – hot water is provided by a hot water tank with an integrated heater element. The water is supplied directly into the tank under the pressure as connected into the back of the unit. The water fills the tank and hot water is dispensed by
displacement. The water flow is controlled by solenoid valves on all models.

Direct Chill
Borg & Overström Direct Chill utilises innovative technology to chill water instantly. We recommend this system for more demanding environments
because of its optimum dispense performance and unrivalled hygienic qualities. Superior to the gravity
fed Reservoir system, Direct Chill technology chills water on demand for the ultimate drinking experience.

Chilled
On/Off Switch: at rear of machine, switches cooling operation on/off.

Cold Thermostat: At rear of machine.

NOTE: on a Direct Chill model this is located inside.

Cold Button: Push to dispense chilled water.

Reservoir/Direct Chill models – Cold & Ambient only:

Top Green LED: Cooling operation is switched on.

Bottom Green LED: Colour shows compressor is in operation.

Ambient
Ambient Button: Push to dispense ambient water.

Sparkling
Sparkling switch: Switches sparkling operation on/off.

Sparkling Button: Press to dispense sparkling water.

Yellow LED (bottom RH): Colours to show the sparkling operation is switched on.

Hot
On/Off Switch: The hot water heating mode is controlled by a switch on the back of the unit, next to the cooling mode switch. This switch is labelled “Hot”.

Hot Thermostat: regulated by a pre-set, nonadjustable sensor on the tank.

Hot Button: press to dispense hot water.
Lock Button: toggles on and off the dispense
of hot water.

Red LED (on hot water icon): Colours to show heating mode is enabled.

Reservoir/Direct Chill Models – Cold & Hot only:

Top Red LED: Hot operation is switched on.

Top Green LED: Cooling operation is switched on.

Bottom Red LED: Heater element active according to thermostatic demand.

Bottom Green LED: Colours to show cooling down operation is active.

10A Fuse: On rear of machine, integral with IEC socket.

On reservoir models remove the Carbon bag from the cold tank. Connect and turn on the water supply. Then connect the power supply.

Dispense from all options (to confirm water supply).

Turn on the cold switch (located at the rear on the unit) to begin the chilling process. Turn on the hot switch (also located at the rear on the unit) to activate the heating element.

The relevant indicator lights will be lit.

Flush through 10 litres of water before use.

Chilled Dispense:
When the top Green LED is on the cooling circuit is activated. When the bottom Green LED is on the compressor is operating.

Hot Dispense:
When the top Red LED is onheating circuit is activated. When the bottom Red LED is on the heating element is activated.

Sparkling Dispense:
When the Yellow LED is on the carbonation circuit is activated.

Allow up to 1 hour for the water to reach its minimum
temperature.

The temperature of the chilled water can be set from 4c to 10c. When the chilling LED is off the set temperature has been reached. This can take up to one hour.

NOTE: All maintenance operations must be carried out with the dispenser switched off.

Please make sure the machine is completely disconnected from the electricity before carrying out any maintenance work.

Turn off the water supply.

To drain cold and ambient units, simply push each dispense button until no water dispense. For cold and hot dispensers push the dispense until no water dispenses and then remove both drain port caps to empty the water tanks.

NOTE: Before beginning the sanitation process please ensure that water is turned off at the mains and refer to the sanitisation liquid MSDS documentation for further information. Use bioguard hand gel and ensure gloves are worn.

For reservoir variants always ensure that the hot water outlet is plugged before beginning this procedure (use gloves). Never push the hot water button during the sanitisation procedure.

Remove the top panel by undoing 2x screws at the rear
of the dispenser.

Remove the polystyrene lid. Gently lift the plastic lid from the tank, taking care not to disconnect the plumbing.

Dispense chilled water until the baffle plate is accessible.

Insert the Hot tank sanitisation plug into the centre of the hot tank, press down firmly. Refit the plastic lid to the tank.

Follow steps 1-12below.
Once the sanitisation procedure is complete repeat step 3 and reverse step 4 above, then remove the Hot tank sanitisation plug and replace the plastic lid firmly on the tank, then replace the polystyrene lid and top panel. Ensuring the screws are done up before leaving.

Briefly press chilled/ambient dispense buttons to release internal water pressure from the machine.

Remove the existing cartridge.

Add 25 ml of Sterizen® 30 Internal Water Cooler Sanitiser fluid to a clean and empty service filter cartridge.

Connect to machine.

Turn on incoming water, allow service cartridge/doser to fill.

Dispense water using the cold button until the water
appears pink. Repeat with sparkling button if present.
Briefly press the ambient button too.

Leave the solution inside machine for sanitisation
(minimum 5 minutes) while thoroughly cleaning the
machine externally, pay particular attention to the dispense faucet and buttons.

Remember to include the drip tray. If a Waste Overflow
System is fitted, empty this and flush through with a small amount of sanitisation fluid if needed.

When the external cleaning (after a minimum of 5 minutes) is completed, flush the machine using the chilled button with clean water until the dispense water runs clear. Repeat briefly with the ambient button.

Turn off water and remove the service filter. Retain service filter for reuse.

Fit new filter. Turn on incoming water supply.

Pre-flush the new filter to waste using the ambient button until the water appears clear and is free of air. Flush through a small amount of water to check all functions.
