connection to each exposed metal part must be less than 1Ω. Use the
power cable supplied. It is the responsibility of the installer to ensure
the power point is earthed.
• All installation and service work must be completed by trained and
suitably qualified tradespeople. Faulty operation due to unqualified
!
persons working on this product, may void warranty coverage.
• As the installer, it is your responsibility to supply and install all valves as
required by local regulations and relevant standards.
• The InstaTap is rated for 230V 50Hz AC operation.
• Do not remove the cover of the under counter chiller, without first
isolating them from the power supply.
• Connect only to a potable (wholesome, cat1) mains water supply.
• Never locate the system near, or clean with water jets.
• Do not expose the InstaTap system to the elements of nature it is not
suitable for outdoor use.
• A pressure limiting valve must be fitted for mains water pressures above
the max. limits stated.
• Use of tools can be hazardous, assess the risks before you start.
• A clearance envelope around the under counter appliance must be
provided to allow adequate ventilation and service access for its safe
and effective use.
• Valve and fitting threads must be sealed appropriately with PTFE tape
where compression seals are not provided.

appliance, ensure power supply cord is not trapped or damaged. If
damaged they must be replaced by an Instanta service provider or a
qualified electrician.
• Instanta cannot be held responsible for any appliance malfunction if
the water pressure exceeds that stated. If in doubt, consult your water
supply company.
• The install rail supplied must be fitted to ensure compliance with the
S.I.1999 No.1148 The Water Supply (Water fittings) Regulations 1999
Schedule 2 requirement.
• Ensure that all installed silicone tubes are shaded from direct sunlight.

• If your InstaTap is left idle before use, for water taste and quality
reasons, any non-use of more than 48 hours, we recommend a system
flush be performed. On first use after a period of non-use, run the
chilled function for 60 seconds to flush the filter and system. Not
flushing the system may affect the water quality. If taste or water quality
issues persist, a filter change and sanitisation may be required.
• The new detachable hose sets supplied with the appliance must be used.
Do not re-use old hose sets.

SECTION 6 Installing the under counter appliance
6.1 Installation preparation
• Before Installation, ensure there is an electrical socket in close proximity to
the intended site of the under counter chiller.
• Install the dispense font in the counter BEFORE locating the under counter
chiller inside the cupboard.
• (This prevents debris when making the cut-out in the counter-top, from
falling onto the under counter chiller, and also allows more space to work
from underneath, making it easier to fit the dispense font).
• Refer to separate installation instructions supplied with the dispense font.
• To achieve the requirement for adequate airflow:
• Cold air is directed into the base of the cupboard, by cutting a slot out of
the cupboard base (just above the kick space) and fitting the stainless steel
grille, supplied.
• Hot air is expelled from the top of the cupboard by cutting a slot out of the
cupboard door or side and fitting the grille, supplied.
Use instructions supplied with individual kit parts.
!
!
Use of tools can be hazardous, assess the risks before you start.
!
!
!
!
!
!
!
!
Valves and fittings must be sealed with PTFE tape if compression
seals are not included.
Water supply pressure range 0.2 - 0.5 MPa. If the mains water
pressure is below 0.2 MPa a fault could arise.
To avoid damage, do not use any solder connections whilst pipes
are connected to the appliance.
CHECK & CONFIRM that the front vent-cover plate on the under
counter chiller has already been removed by the factory, as this is
the main air-intake route to the chiller.

14 Installation instructions & user guide
T210081 v1.00 Sept 2023 - InstaTap Commercial chilled
The InstaTap I2CC20** dry chiller is designed to be fitted underneath a
counter-top, in close proximity to both mains water and electrical supplies.
The chiller is intended to be installed in conjunction with the dispense font,
water install rail and water purification filter…all supplied.
Always site the appliance in a well-ventilated room of sufficient size (avoid
small alcove-rooms with no ventilation).
When installing the I2CC20** under counter chiller, there are TWO very
important parameters which MUST be achieved for a correct installation and
to meet the conditions of the guarantee:
• GOOD VENTILATION AND AIR-FLOW: It is essential that the unit has good
air-flow which is directed into the front air-intake grill.
• HEAT EXPELLED: It is essential that warm exhaust air expelled from the
rear of the under counter chiller, has an effective outlet towards the top of
the cupboard space (to avoid warm air from being re-circulated).
SECTION 6 Installing the under counter appliance
Failure to provide sufficient air-flow an ventilation will seriously
impair the performance of the chiller and may cause
over-heating.
!
6.2 Positioning and ventilation - in cupboard installation
• A clearance envelope both sides
and above each under counter
appliance MUST be provided to
allow service access and ventilation
for the safe and effective use of the
appliance.

6.2.2 Ventilation grilles
• Adequate ventilation must be
provided to allow cold air to be
drawn into the bottom of the
cupboard, and hot air expelled from
the top of the cupboard.
• The inlet and outlet vents supplied
with chilled water systems MUST
be installed to keep cupboard
temperatures below 30oC
• The inlet vent should be placed
directly in front of the under
counter chiller.

Use instructions supplied with the individual system components.
Valves and fittings must be sealed with PTFE
tape if compression seals are not included.
6.4 Connect the water supply
Water supply pressure range 0.2 - 0.5 MPa.
If the mains water pressure is below 0.2 MPa a fault could arise.
To avoid damage, do not use any solder connections whilst pipes
are connected to the appliance.
Instanta cannot be held responsible for any appliance malfunction if the
water pressure is not within the range stated. If in doubt, consult your
water supply company.
• Connect to a wholesome (cat 1) cold drinking water supply using 15mm
copper pipe-work to the install rail.
• The install rail must be fitted, it includes an isolation valve to turn off the
water supply for servicing or repair, as well as a back-flow prevention device
to prevent water from the appliance re-entering the mains water supply.
• When installing ‘push fit’ fittings and pipe-work observe push fit best
practice, see page 19.
• When installing the filter head, use the instructions supplied with it.
• To install and set the water block, use the instructions supplied with it and
refer to page 20.
• When installing the 93705 filter, use the instructions supplied with it and refer
to page 27. The filter must be flushed after installation, see page 28.
• Connect to the appliance water connection point with the 3/4” - 1/4” PF
adaptor and 1/4” flexible pipe supplied.
