Introduction
Please Note: This Product Manual is intended for use by qualified Service Technicians only.
Use of the advice and material enclosed by the end-user could invalidate product warranty,
occupational insurances and present health and safety risks.
We strongly recommend that this Product Manual is not left with the dispenser or end-user but that
instead training is given regarding the simple function operations.
The Boste BK Series (UDC102 Model) is a range of undercounter water dispensers that are connected to the mains water
supply and dispense water through a proprietary swan-neck faucet that is mounted on a worksurface.
There are two models in the range:
BK5 – Cold & Ambient
BK9 – Cold, Sparkling & Ambient
Both models models have robust steel framed cabinets and attractively injection moulded plastic front, side and top
panels.
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).
Both are 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. We recommend fitting a
Pressure Reducing Valve is fitted to all supplies to regulate the pressure to 3.5 bar/355 kPa.
On the carbonated water model, 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.
Dispense is at inlet pressure and controlled via the 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
The Cold Tank can be drained via the two Drain Port on the rear of the machine.
The level control system also incorporates a leak detection device within the cabinet which switches the
machine off in the event of detecting water.
