Range Overview
A range of compact countertop water dispensers, available in two different operational
types:
• 818 Cold and Ambient (Low Pressure Tank System)
• 818 CS Cold and Sparkling (Direct Chill System)
Both types are available as:
• Countertop
• With optional base cabinet (Close fitting to create Floor Standing style appearance)

All Types
All B&O 818 Sport models are self contained machines with robust steel framed cabinets and attractively injection
moulded plastic front, side and top panels. There is sufficient space internally for most filters to be fitted behind
the right side panel.
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).
Optional Floorstanding Base Cabinet
A sturdy, steel-sided cabinet with an opening door and service access ports in the rear panel. Adjustable feet are
standard.
818 Cold and Ambient Model
Water is fed into the insulated Cold Tank under mains pressure. We strongly recommend fitting a Pressure
Reducing Valve is fitted to all supplies to regulate the pressure to 3.5 bar/355 kPa. Water bypasses the cold tank
for the ambient dispense option. The cold tank is chilled via the outer evaporation coil of the capillary controlled
refrigeration compression system.
Dispense is at inlet pressure via the DC current operated solenoid valves.
The Cold Temperature is thermostatically controlled via the adjustment screw on the back of the machine. This
setting is factory set and is not necessary to adjust in most cases (see Controls).
The Cold Tank can be drained via the lower of the two Drain Ports on the rear of the machine.
818 Cold and Sparkling Model
A Direct Chill cold water dispenser where water is used as the cooling medium in the Direct Chill tank. This is
automatically filled and controlled by the level control system upon installation. This tank is then chilled via the
outer evaporation coil of the capillary controlled refrigeration compression system.
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.
The level control system also incorporates a leak detection device within the cabinet which switches the machine
off in the event of detecting water.
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).
The Cold Tank can be drained via the upper of the two Drain Parts on the rear of the machine.

Base Cabinet
Either 818 model is designed to fit straight onto the top of the cabinet. Ensure the feet of the machine securely
locate in the nesting positions.
The Door Panel is hinged and fastened with Magnetic Catches. The Cabinet can be levelled using the adjustable
feet. Service entry points are positioned in the back of the cabinet.
Every Base Cabinet is supplied with a Level Sensor Kit, comprising:
• Water Container
• Sensor Unit (c/w 2 no. CR3032 batteries)
• Drip Tray with Drainage Outlet
Simply exchange the Drip Trays, connect the Drainage Tubing, that is pre-fitted down the front left hand side of the
cabinet, into the top of the container and remove the transit seal from around the float shaft to enable operation.
A warning tone will sound when the water rises. Upon emptying the container, the warning tone will stop.

Operation
1. After connecting the water the tank will begin to fill. Put the
plug in the socket and the indicator lights will be lit. Try
pressing the cold water button to see if water comes out.
When water flows out of the dispenser, the cold power switch
may be turned on and it is ready to use. Please do not turn on
the power switch until water flows out of the machine, to avoid
damage. Allow up to one hour for minimum temperature
water. Flush through 10 litres of water.
2. When the cold power switch is
turned on, the chilling LED will be
on. When the set temperature is
reached, the LED will go out.

chilling LEDs will show. The temperature of cold
water can be set from 4°C to 10°C. When the chilling
LED is off the set temperature has been reached.
1. After connecting the water the tank will begin to fill
with water. Plug in the power and the indicator LEDs
will be on. Try pressing the cold button until the water
comes out. When water flows out of the dispenser,
the power switch may be turned on and the machine

This machine is equipped with a leakage detection device. When leaking is detected, the power will be cut off
automatically.
When the power has been cut off:
1. Unplug the machine, then remove the left side plate.
2. Detection probe found in the bottom front left hand corner and dry probes and machine with a dry cloth.
3. Plug in the machine to test if the leaking has stopped.
