Model Overview
© Copyright Borg & Overström.
This manual is printed by Borg & Overström and shall not be reproduced or copied in anyway.
All Models
All models are self-contained machines
with robust steel framed cabinets and
attractively injection moulded plastic
front, side and top panels. There is
sufcient space internally for most lters
to be tted behind the door 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).
The level control system also
incorporates a leak detection device
within the cabinet which isolates
the water to the unit in the event of
detecting a water leak.
Chilled
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).
Ambient
Water bypasses the cold tank for the
ambient dispense option.
Sparkling
Water is chilled as it passes through
the coil immediately before dispense
or being pumped under pressure into
the carbonator which it tted inside the
same coil. The carbonator is also level
controlled and allows the sparkling
effect to occur through saturation with
CO2.
Hot
The hot water is provided by 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 lls
the tank and hot water is dispensed. The
water ow is controlled by a solenoid.
Introduction
A range of compact water dispensers, available in four different operational types:
• Chilled & Ambient
• Chilled, Ambient & Sparkling
• Chilled, Ambient & Hot
• Chilled, Hot & Sparkling

CO2 Bottle Installation (Sparkling Versions Only)
IMPORTANT! ALWAYS ENSURE SECURITY CLIPS ARE
USED ON ALL WATER AND CO2 CONNECTIONS.

hour
Attach the regulator to the disposable
CO2 bottle, ensuring the regulator is
closed.
Connect the assembled CO2 bottle and
regulator to the machine using 1/4 inch
pipe.
After completing the water installation,
turn on the soda power switch and the
pump will run. Do not open the regulator
valve until the carbonated switch has
been turned on.
We recommend between 3.5 - 5 bar.
Do not exceed 5 bar pressure.
Flush through approximately 10 litres of
water. Check and adjust the CO2 pressure
accordingly.
It will be necessary to leave the machine for
up to 1 hour for sparkling water to develop,
by absorbing the CO2.
