Delivery Checklist
Before starting installation, check that you have
the following parts;
• Catering Water Boiler
• Drip-tray
• Drip-tray drain tting
(optional - for connecting front drip-tray
to a permanent waste/drain)
• Tapered rubber bung
(optional - for blanking o front outlet
if rear-overow outlet is preferred)
• White water inlet hose (3/4”BSP connection)
• User instructions
Technical Specification
Installation
The boiler must be installed on a horizontal
work surface with sucient 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).
Do not block ventilation holes in boiler case.
Connection to Mains Water Supply:
Connect the WRAS approved water lling hose
supplied (¾” BSP) to the inlet connection point
on the underside 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 ⅜”(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, t a suitable pressure reduction valve.
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.

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 tting kit provided.
If preferred, and as an alternative, the overow-
outlet which enters the front drip-tray, can be
blocked o using the tapered rubber bung
provided and the alternative overow-outlet at
the back of the machine (underside), connected
to a permanent waste/drain.
IMPORTANT: Whichever overow connection is
chosen, the diameter of the pipe used must be
no less than 15mm.
Failure to connect the overow-outlet to
a permanent waste or drain, could lead to
property damage from ooding.
If in all circumstances, it is absolutely not
possible to direct the boiler overow-outlet to a
permanent waste or drain, then the mains water
supply to the boiler should be isolated and the
unit switched o 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. Screen will light up Red and
will run through an initial self-diagnostic check
before starting to ll with water (screen reads;
“NOT READY FILLING”).
• Once primed with water, the boiler
will begin to heat (screen reads;
“NOT READY HEATING”).
• When the correct temperature is achieved,
the display will change from Red to White
and will read “READY”, displaying the water
temperature in degrees C. A warning message
(CAUTION HOT WATER) will also be displayed
and the push button will illuminate Red.
• The boiler will then continue in a heat/ll cycle
until the tank is at full capacity. (During the
heat/ll cycle, small amounts of water are
added to ensure the water is always at the
correct temperature).
IMPORTANT NOTE: In normal daily use, the
boiler may be used as soon as the “READY”
message is displayed, but on rst install,
wait 15 minutes before starting to use.
• The boiler is now ready for use.
• Place cup/teapot on the drip-tray and press
& hold the Red illuminated button to dispense
hot water. “CAUTION BOILING WATER”
message will ash reminding the user to
exercise caution.
• NOTE: The boiler will dispense “on-demand”
which is the default setting (e.g. push & hold
button to dispense water – release button to
stop dispensing). See below for optional
“TIMED” dispense:
4

Optional “Timed” Dispense:
This function is appropriate when the cup/teapot
being lled is always the same size/capacity.
To change boiler from “on-demand” default
setting to “Timed” dispense:
• Switch o on front of unit.
• Unplug from mains power supply and
wait 10 seconds.
• Plug boiler back in and at the same time,
press & hold the dispense button for
5 seconds.
• Boiler will either start to ll with water or
the dispense button will begin to ash
(depending on water level in tank).
• Place vessel on drip-tray.
• Press & hold the dispense button to ll
vessel to the required level. Release button
to stop dispense (NOTE: This can be
repeated as many times as necessary,
to get the level correct).
• Once level in vessel is correct, press
the ON/OFF button (below display) to
save the measured dispense amount
(this saves the setting and puts the
boiler into standby mode).
• To continue, switch boiler back on by
pressing the ON/OFF button again.
• The boiler will now dispense the measured
amount into the cup/teapot, each time the
button is pressed.
Top-up Feature:
• At the end of the timed dispense cycle,
the “CAUTION” message will continue to
ash for a further 5 seconds. During this
5-second window, the water level in the
cup or teapot can be topped-up by simply
pressing & holding the dispense button.
NOTE: Once the “CAUTION” message stops
ashing, the top-up facility ends and the
boiler reverts back to timed dispense mode.
Regular Daily Use
Switch boiler on and wait for the screen to
turn white and show “READY” message and
dispense button to turn red. The water will
then be at the correct temperature. (the unit
will not dispense until the water has reached
temperature and button is illuminated).
Dispense water by pressing illuminated
push-button.
Filter Counter (optional if a filter
or softener has been fitted):
If an external lter/softener is tted to the unit
there is an optional lter-counter installed in
the software. This counter measures the water
passing through the boiler and reminds the
customer (via the display screen) to change the
lter when required. Note: This counter is set
to ‘Off’ as standard.
To enable lter-counter, proceed as follows:
• Turn machine o on front panel.
• Press & hold “on/o” button
(for approximately 12 seconds) until red
screen shows “PR” in centre of screen,
then release button. Temperature setting
is displayed.
• Press & hold button (long push) for
approximately 5 seconds until screen
changes to show “empty lter symbol”
(default lter setting).
• Press button (short push) to scroll between
the dierent lter settings;
SOFT (13001 litres)
MEDIUM (9001 litres)
HARD (6001 litres)
EMPTY FILTER SYMBOL (No Filter counter).
• With the required lter setting selected,
Press & hold button (long push) for 4 seconds
to save.
• Press & hold button (long push) for
approximately 6 seconds until display
goes blank.
• Turn machine back on again.

• TO RE-SET & CONFIRM NEW SETTINGS;
…Press & hold button, screen will go
blank but continue to hold, until “READY”
message is displayed on a red screen.
• The unit can then be switched back on
and used.
If in doubt as to the hardness of water supplied
in your area, consult your local water authority
Preventative Maintenance:
AQ35/KIT – The Instanta AQ35 high-ow
multi-lter delivers the best quality of water
by removing sediment and impurities such as
chlorine. The lter also reduces scale build-up
which results in lower running costs, improved
energy eciency and longer life expectancy.
Filter capacity: up to 13,500 litres.
Available from Instanta Spares Department:
01704 501114.
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.
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 ecient
operation, minimise energy consumption,
and also retain the water quality.
To de-scale:
• Disconnect machine from power supply and
allow to cool.
• Insert a at blade between lid and casing and
twist to pop o the outer-lid.
• Remove tank-lid (four xing 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 dicult to remove can be
dissolved by using a de-scaling solution.
• 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.
