Installation
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.
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.
Wherever possible, we strongly recommend that it is
connected to a permanent waste.
We have provided two overflow outlet/connection
points to choose from;
1). The normal overflow is directed to the
drip-tray.
2). Alternative overflow is at the back of the
machine.
If the drip-tray option [1] is to be used for the
overflow, we can supply a 15mm fitting kit (Pt. No:
DTK2) available from Instanta Spares Department
(01704 502905). This can be fitted into the base of
the drip-tray in place of the rubber blanking plug.
If the rear overflow option is chosen [2], the front
overflow-pipe [behind curved-front panel], must be
blocked-off using the tapered-rubber blanking bung
provided. Pipe-work should then be provided
between the rear-overflow connection
[1/2”bsp-15mm] and a suitable waste/drain
[NOTE: Whichever overflow connection is chosen,
the diameter of the pipe used must be no less than
15mm and an air gap provided within 300mm of
the connection point. Failure to provide an air gap
within this distance could cause an air lock which
would stop the water discharging in the event of an
overflow].
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.
The screen will run through an initial self-diagnostic
check before starting to fill with water (screen reads;
“BOILER FILLING”).
Once primed with water, the boiler will begin to heat
(screen reads; “BOILER HEATING”).
When the correct temperature has been reached, the
display will simply read “BOILER READY”.
The boiler will then continue in a heat/fill cycle until the
tank is at full capacity. (During the heat/fill cycle, small
amounts of water are added to ensure the water at
the tap is always at the correct temperature).
IMPORTANT NOTE: In normal daily use, the boiler
may be used as soon as the “BOILER READY”
message is displayed, but on first install, wait at
least 15 minutes before starting to use.
Regular Daily Use
Switch boiler on and wait for the screen to show
“BOILER READY”. The water will then be at the
correct temperature.
Dispense water by pressing button.
(CAUTION: Boiler dispenses near-boiling water).
Eco Mode / Power Saving
The ECO mode is activated by pressing the ECO
button. The screen reads “ECO MODE ACTIVE”.
This saves energy by switching the boiler operating
capacity to half volume, ideal on quiet days in the
season. Simply push the ECO button again to revert
to full capacity.

Standby Power Consumption: The typical amount
of energy used by the boiler when idling (not used) is:
0.09kw/hr
Leave on overnight or switch off? As a general rule
of thumb…a 12-litre capacity water boiler such as
the DB2000 which is left idle for 10 hours or MORE,
would be better switched off and back on again the
following day. If left idle for LESS than 10 hours, it
would be more energy-efficient to leave it switched
on.
Program Mode
The LCD display in conjunction with the On/Off
button gives access to the program menu which
allows various settings to be selected.
Most of the menus should not be accessed or
changed because they are factory set, however,
water temperature and optional lock mode may need
to be set-up on site.
To access the program menu:
• Switch the boiler off and back on again - within
a few seconds of the boiler being switched
on again, press and hold the On/Off button in
for approximately 10 seconds, until the display
reads “PROGRAM MODE”.
• Continue to press the On/Off button to proceed
through the menu selections until the desired
mode is reached.
• To select mode, hold button in for 3 seconds.
PROGRAM TEMP SET:
The boiler temperature is factory set to operate at
around 98oC. This temperature can be adjusted
in 1oC increments between 80 and 990C. Follow
instructions as above, scrolling through menu until
“TEMP SET” is reached - hold button down for 3
seconds to select. Continue pushing button until
desired temperature is displayed - push and hold
button in for 3 seconds to set temperature. Continue
to scroll through menu until “PROGRAM EXIT” is
displayed – again push and hold button for 3 seconds
to exit program mode.
PROGRAM LOCK [OPTIONAL]:
The DB2000 has an optional programmable locking
system, which can restrict its use where Health and
Safety is a concern or in High Security environments.
Before activating “Lock Mode”, the optional key
(supplied) must be synced to the machine as follows:
a) Enter program mode as described above and scroll
through menu until the display shows “PROGRAM
LEARN KEYS”. Hold for 3 seconds to select
“LEARN KEYS…WAITING”. Touch the key against
the sensor (situated directly below LCD display
window) – When a new key is touched, a short bleep
can be heard and the display will show “LEARNT”.
To continue through the menu, push & hold button
for 3 seconds.
b) Continue scrolling through menu until “PROGRAM
LOCK MODE” is displayed – push and hold button
for 3 seconds to select. There are four distinct lock-
modes to choose from (push button to scroll through
each option) as follows:
1) NONE/OPEN - (Standard default setting) the key
function is disabled.
2) TOGGLE - Using the key fob turns the boiler on
and off sequentially.
3) TIMED - The boiler can be used for a preset time
(see below).
4) ONE-SHOT - A single drink…(plus 4 seconds of
“top-up” in case button was released too quickly
or drink has settled).
TIMED (3) - If “TIMED” option is selected, scroll
through menu until “PROGRAM OPEN TIME” is
displayed. Push and hold for 3 seconds to select
– display shows “OPEN TIME” and the number
of minutes. To set open time, push the ON/OFF
button to INCREASE minutes and the ECO Button
to DECREASE minutes. Press and hold for 3
seconds to confirm [Open Time determines how
long the machine stays available for use, in minutes
(programmable between 1 and 200 minutes].
c) Choose the desired lock-mode: push & hold button
for 3 seconds to select.
d) To exit program mode, scroll through menu until
“EXIT PROGRAM” is displayed – push & hold button
for 3 seconds to exit.
Other Menu Options for Lock & Programmable Keys:
PROGRAM CHECK KEYS: This allows the validity
of keys to be checked - the display shows “CHECK
KEY…WAITING” and acknowledges any valid key
with message “VALID KEY” and a short bleep (when
key is touched against the sensor).
DELETE KEYS: This allows the deletion of a specific
key. The display will show “DELETE KEYS…
WAITING”. Any key now touched against the sensor
will be deleted.

ERASE ALL: This function clears all keys from the
memory. It will ask for confirmation by pressing “eco”
button. Should you not wish to clear the keys, simply
press the “On/Off” button as normal to exit the menu.
Each DB2000 boiler can sync with 24 different keys,
all with a unique combination. A key can be learnt by
more than one machine to allow its use in multiple
areas of the same building.

Cleaning
The external surfaces of the machine can be kept
clean by wiping with a damp cloth. A good quality
stainless steel cleaner will keep the machine in its
original condition. The plastic top trim may also be
cleaned with a damp cloth. Do not use abrasive
material on the outer surface of the machine.
Maintenance & Service
Information
The boiler should be periodically checked for scale
build-up. The frequency depends upon hardness
of the water and whether or not an effective scale
reducer is fitted.
Apart from cleaning/de-scaling the level sensors and
tank, no regular maintenance should be required.
DE-SCALING:
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.
Full de-scale of Tank & Probes:
• Disconnect machine from power supply.
• Empty the machine and allow to cool.
• Remove outer-lid (spring-clips).
• Remove tank-lid (four/six 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.
• Wipe clean the level sensing probes
(using non-metallic scourer).
• 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.
Clean & de-scale the Probes:
• Disconnect machine from power supply.
• Remove outer-lid (spring-clips).
• Remove tank-lid (four/six fixing screws).
• Lift out the evaporation plates (inside of tank –
Remember order of removal).
• Wipe clean the level sensing probes using a
non-metallic scourer. It is important to clean
the white insulators as well.
• Replace evaporation plates, tank-lid and
outer lid.
Service Warnings & Fault
Diagnostics
The DB2000 is fitted with an intelligent fault
diagnosing system. There are two levels of diagnosis.
1 Simple warnings - accompanied by the
illumination of a red exclamation mark.
Your boiler will continue to operate as normal
whilst displaying these warnings.
2 Critical faults - accompanied by the illumination
of a red spanner.
6

SIMPLE WARNINGS (1) The following messages may be seen. The display will
alternate between the boiler status and the warning
message. To clear message, switch boiler off at the mains
supply and back on. These messages, which are not
critical, should be dealt with when it is convenient;
CHECK WATER Interruption in water supply. Check stop valve is turned
on and no kinks restricting inlet hose.
Check no debris in the water inlet valve.
Message can also indicate low in-coming mains water
pressure.
NO WATER
Can occur on initial installation or following a service/
maintenance.
Lower probe cannot sense water after 6 minutes.
Usually caused by interruption in water supply.
Check stop valve and inlet hose etc. (as above).
Fault can also be caused by limescale (see Message
CLEAN PROBES below). Once water supply is rectified
or probes cleaned, boiler must be switched off and back
on to reset.
CLEAN PROBES
(+1 or +2)
Limescale build up on one or more of the 5 level
sensors.
(+1) indicates that the lower sensor is coated in scale
(+2) indicates that one of the upper 3 sensors are coated
in scale. Clean probes as described in “DE-SCALING”
above.
CRITICAL WARNINGS (2): In the event of a serious malfunction, the Red spanner
in the display will illuminate together with the message
CALL SUPPLIER, alternating with one of the following
messages;
THERMISTOR OC Temperature sensor has become disconnected or is
faulty. Contact supplier.
HEAT/THERM FAIL Either the Over-boil or Boil-dry safety cut-outs have
activated. Switch boiler off and back on after 5 minutes.
If the Over-boil cut-out has operated, the boiler will reset
and work as normal.
If the Boil-dry cut-out has operated, the boiler will not
heat and the message will reoccur in about an hour.
OVERFILL Water level has risen to the highest Overfill sensor.
If a previous CLEAN PROBES message has been
ignored, simply clean the probes as described in
“DE-SCALING” above.
If this does not solve problem, the boiler has overfilled.
This can be caused by a faulty water inlet valve or very
high or low incoming water pressure. Contact supplier.
The majority of possible faults have been covered
above. However, in certain circumstances, safety
controls within the boiler may be activated. There are
two resettable safety cut-outs in your boiler:
1). Over-boil safety cut-out: activates should the boiler
produce excess steam. This can be due to:
• Limescale within the tank
• A temporary interruption in the water supply
• Over use of the boiler, beyond its capacity
• A faulty temperature sensor (covered by
Warranty)
2). Boil-dry safety cut-out: this will activate if the boiler
has been boiled dry, for example due to lime-scale
build up or water starvation.
The safety cut-outs are manually resettable.
Safety First: Isolate from mains power
supply before resetting. If in doubt, first
contact Instanta Service Department
