Identify a suitable location for the undercounter unit. It should
be positioned within 1.0m of the faucet, and within 2.0m of
suitable services connections. Allow enough space to t the
ventilation ducting system.

When planning and providing
for the connection to the

easily accessible service isolator
ttings and for the position of an
external water lter.
Identify a suitable position for the
swan neck faucet. A 33-35mm
(max) hole is required.
When positioning to drain over
an existing sink bowl, allow for
the reach of the swan neck or
otherwise the position of any
optional drip tray.

Also allow for the height of
the swan neck under any

Carefully form the needed hole,
using the correct type of cutter
for the work surface material.
Observe all local occupational
health and safety requirements.
Remove the back nut and washer
from the faucet and carefully
feed the connecting pipe tail
and ribbon cable through the
hole formed in the work surface.
Ensure the sealing O ring is pre-
tted in the base of the faucet.
You may want to apply a thin
bead of silicone sealant also.
With the faucet control panel in
the right position, carefully ret
the back washer and nut. Take
care not to over-tighten.

Ventilation System Installation
When Borg & Overström undercounter units
are installed inside a cabinet or
housing, adequate ventilation is
recommended to ensure that they operate
satisfactorily.
During a cooling cycle it is normal for the
unit to produce heat, and the purpose of
ventilation is to provide a supply of air
that can absorb the generated heat which
would otherwise accumulate inside the
cabinet or housing, and reduce the cooling
performance of the unit. The amount of heat
generated by the cooling cycle depends
directly upon the amount of usage – the
higher the usage, the more heat produced.
To provide adequate ventilation we
recommend that air grilles/vents are tted
as supplied (or vent apertures formed) in
the cabinet to allow an airow as shown
below. Normally this should be enough for
all situations.
Important: Before making any cuts into the
cupboard or kick board, ensure the area to
be cut is free from water pipes or electrical
cables. There is a risk of serious injury
or death if electrical cables are cut, and
signicant damage to property if a water
pipe is cut.
Using the template provided, carefully mark and cut the aperture to the edge of the cabinet.

Borg & Overström GB10Install & Operation Manual
Situate the Simple-t ventilation base in place centrally over the aperture. Ensuring that there is a minimum of 30mm air gap to
each side.

The S2 appliance must be placed carefully in position on the ventilation base to ensure the chimney is located correctly in the
chimney aperture at the rear of the base. After installation the vents at the front of the cabinet and to the sides of the ventilation base
must not be obstructed. Any obstructions will adversely affect the airow to the appliance causing potential for poor performance,
over heating or fridge failure.

Locate the machine in a
suitable enclosure, ensuring
that the supplied ventilation kit
can be installed.
Connect the u1 tap to the
water outlet.
Connect the faucet connection
harness to the tap control
panel membrane.
*Connect the CO2 supply
from gas regulator, ensuring
the pressure is set to max 58
PSI (4 bar), and turn on the
supply.
Connect the chiller to the
water supply and open the
mains supply isolation valve.
Connect the unit to the
electrical supply and turn on.
After approximately 10
minutes, the compressor and
fan will stop as the chiller has
reached its normal operating
temperature.
*The carbonator should be
purged of air by activating the
sparkling water dispense for
approximately 20 seconds.
*Isolate the water supply
and activate the sparkling
water dispense. When the
water system has emptied,
allow gas to be expelled for
approximately 5 seconds.
Immediately after this 5
second period restore the
water supply and allow the
system to rell.
Dispense ambient, still and
sparkling water, in turn,
to purge any air from the
system. The time to do this
may vary depending on the
length of pipe between the
unit and the tap.

lid away
Locate the ow control adjuster,
this can be found on top of the
carbonator can, connected to
the central port of the can.
Loosen the lock nut, but do
not remove. Flow can then be adjusted
by turning the adjuster screw,
anti-clockwise to increase ow
and clockwise to restrict ow.
After each adjustment the ow
rate should be timed.
Sparkling Water Flow Rate - Sparkling Versions Only
NOTE: The soda water ow rate is set to 35ml/sec at a CO2 pressure of 58 PSI (4 bar). To
adjust the soda water ow rate follow these steps:
Once the correct ow rate is achieved reverse steps 1, 2 and 3.

Pre-ush the new lter 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.
Pay particular attention to the
dispense faucet and the push
button controls. For this use
Bioguard External Sanitiser &
Clear Spray and Sanitising
Wipes.
Attend to any cosmetic marks
with Bioguard Rejuvenator &
Protector as needed.
Remember to include the drip
tray. If a Waste Overow
System is tted, empty this
and ush through with a small
amount of sanitisation uid if
needed.

Please note that this sanitisation uid contains 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.
Avoid skin contact and wear
protective gloves when
