Installation [All Models]
The boiler must be installed on a horizontal work
surface with sufficient strength to support its weight.
Locate in an area where there is adequate space to
use the boiler safely (e.g. free from risk of congestion
and tripping hazards).
CONNECTION TO MAINS WATER SUPPLY:
Connect the WRAS approved water filling hose
(3/4”BSP) to the inlet connection point on the back
of the boiler and the other end to the mains water
supply, via an accessible isolating tap with a ¾”BSP
thread.
IMPORTANT: If micro-bore pipe is used instead of the
inlet hose supplied, the size must be minimum OD
3/8”(10mm).
The water supply must have a pressure not
exceeding 7bar (96psi), and no lower than 2bar
(28psi).
NOTE: If your water pressure exceeds 7bar, fit a
suitable pressure reduction valve.
*To meet WRAS installation requirements, an
approved single-check valve providing backflow
prevention protection, should be fitted at the point
of connection between the water supply and the
appliances.
NOTE: Water that has been treated by the Reverse
Osmosis process can become aggressive (due to lack
of minerals or Ions), and in extreme cases can cause
leaching and corrosion of pipes, fittings and other
metal parts within the appliance.
If the appliance is being fed by water treated by
Reverse Osmosis, we recommend that the water is
tested regularly.
If you have any queries in respect, please contact our
customer services team.
We regret that Instanta cannot be held
responsible for any machine malfunctions if the
water pressure exceeds that stated. If in doubt,
consult your water supply company
ELECTRICAL CONNECTION:
The boiler must be Earthed.
Your machine is supplied with a standard 13amp
bonded plug with a 13amp fuse.

Technical Information
Outer casing and tank are constructed in type-304 and type-316 grade stainless steel.
The tank is fully insulated with high-temperature polystyrene.
The appliance has electronic control of the main functions. This means that the heating,
filling and temperature are controlled precisely within given parameters.

OVERFLOW:
The drip-tray has a limited capacity and is designed
to handle small spillages and drips only. Wherever
possible, we strongly recommend that it is connected
to a permanent waste outlet using the fitting kit
provided.
If preferred, and as an alternative, the overflow-outlet
can be connected from the back of the machine
using an optional rear-overflow kit (Pt. No: ROFK1)
available from Instanta Spares Department
(01704 501114).
IMPORTANT: Whichever overflow connection is
chosen, the diameter of the pipe used must be no less
than 15mm.
Failure to connect the overflow-outlet to a permanent
waste or drain, could lead to property damage from
flooding.
If in all circumstances, it is absolutely not possible to
direct the boiler overflow-outlet to a permanent waste
or drain, then the mains water supply to the boiler
should be isolated and the unit switched off whenever
it is left unattended for long periods (e.g. overnight).
Whilst every reasonable precaution is taken to
prevent an overflow, Instanta cannot be held
responsible for any damage caused as a result of
incorrect installation or blockage of the overflow
or failure to direct the overflow to a safe outlet.
Operation
First Use (once water and electrical connections have
been made);
• Switch boiler on.
AMBER LIGHT will illuminate to indicate that the
boiler is filling with water.
• Once primed with water, the RED LIGHT will
illuminate to show that it is heating.
• When the boiler reaches the correct temperature
the GREEN LIGHT will show that the boiler is
ready.
IMPORTANT NOTE: In normal daily use, the boiler may
be used as soon as the GREEN LIGHT shows, but on
first install, wait 15 minutes before starting to use.
Regular Daily Use
• Switch boiler on
• Wait for the GREEN LIGHT. The water will then
be at the correct temperature.
• Dispense water via the lever tap.
(CAUTION: Take care as boiler dispenses near-
boiling water).
Cleaning
Clean the external surfaces of the boiler regularly to
maintain good hygiene
Empty the front drip-tray regularly
Wipe external surfaces of the boiler with a damp
cloth. Do not use abrasive materials on the outer
surfaces.
Wipe the draw-off tap each day to keep clean and
also prevent lime-scale deposits from building up
around the tap-outlet.
Maintenance & Service
Information
DESCALING:
The boiler should be periodically checked for scale
build-up…see below:
In hard water areas, the boiler should be descaled
on a regular basis to maintain efficient operation,
minimise energy consumption, and also retain
the water quality. The frequency depends on the
hardness of the local mains water supply and whether
or not a filter cartridge/water softener has been
installed.
TO DE-SCALE:
• Safety Caution: Disconnect machine from power
supply
• Empty the machine through the draw-off tap and
allow to cool
• Lift off the outer-lid.
• Remove tank-lid (four fixing screws).
• Lift out the evaporation plates (inside of tank –
Remember order of removal).
• Remove as much scale as possible by hand.
Any scale which is difficult to remove can be
dissolved by using a de-scaling solution.
4 5

• Wipe clean the level sensing probes.
• Flush with copious amounts of cold water to
ensure all traces of de-scaler are removed before
using the boiler again.
• Replace evaporation plates, tank-lid and outer
lid.
DRAW-OFF TAP:
The tap spring and washer components are subject
to ware & tear. It is advisable to keep a spare tap-
spring and washer in case of emergencies.

Service Warnings And Fault Diagnosis
Your boiler is fitted with an intelligent fault diagnosing
system and is able to detect various fault conditions.
Some of these are less serious and the machine will
continue to operate as normal, while others are more
serious and will disable the unit.
Before calling for service, switch the machine off at
the mains supply. Draw-off a small amount of water
and then switch back on after 10 minutes. If the fault
does not clear, call technical support for advice.

SAFETY CONTROLS:
The majority of possible faults have been covered
above. However, in certain circumstances, one of two
different safety controls within the boiler may have
activated;
1). Over-boil Safety cut-out
Activates if boiler produces excess steam.
This can be due to;
• lime-scale within the tank,
• a temporary interruption in the water supply.
• a faulty temperature sensor or internal
component (triac).
TO RESET BOILER; Switch off at the mains power
supply and allow the boiler to cool down for ten
minutes before switching back on (the safety device
should automatically reset).
EARLIER MODELS: The over-boil cut-out will require
a manual reset. Contact Instanta Technical Support
department for assistance with this.
2). Boil-dry Safety cut-out.
This operates if the boiler has been boiled dry,
for example, due to lime scale build-up or water
starvation.
The boil-dry safety switch will require resetting.
Please contact our Technical Support department for
assistance with this.
Safety Caution: Isolate boiler from power supply before
removing any outer panels or attempting any reset.
In any of these events the indicator lamp will flash red
or green or red and green. If the problem reoccurs
contact the Instanta Service Department
– 01704 502911
