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 1.5bar (20psi)
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.
The product can be connected to a standard domestic 13amp outlet.
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 outlet using the fitting kit
provided.
If preferred, and as an alternative, the overflow can be connected from the back of the machine using
an optional rear-overflow kit (Pt. No: ROFK1) available from Instanta Spares Department (01704
502905).
IMPORTANT: Whichever overflow connection is chosen, the diameter of the pipe used must be no less
than 15mm.
NOTE: Where it is absolutely not possible to direct the boiler overflow outlet to a permanent waste as
described above, then for peace of mind, we strongly advise that the boiler be switched off and the
mains water supply isolated overnight.

5
Failure to connect the overflow-outlet to a permanent waste or drain, could lead to property damage
from flooding.
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 light up red and will run through an initial self-diagnostic check before starting
to fill 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 has been reached, the display will change from Red to White
and will simply read “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 “READY” message
is displayed, but on first install, wait at least 15 minutes before starting to use.
•The boiler is now ready for use.
REGULAR DAILY USE
Switch boiler on and wait for the screen to turn white and show “READY” message. The water will then
be at the correct temperature.
Dispense water via the lever tap. (CAUTION: Boiler dispenses near-boiling water).
SETTING & ADJUSTING FILTER MONITOR (Optional):
The unit as a built-in optional filter monitor. This monitor can be used with any external water filter or
softener. To turn this option on as below:
-Turn machine off.
-Press & hold “on/off” button (for approximately 12 seconds) until red screen shows “PR” in top-
right corner, then release button. Temperature setting is displayed.
-Press & hold button (long push) for approximately 5 seconds until screen changes to show
“Empty Filter Symbol” (default filter setting - OFF).
-Press button (short push) to scroll between the different filter settings;
SOFT
MEDIUM
HARD
EMPTY FILTER SYMBOL (No Filter monitor)
Hard and Soft Water: The effectiveness of the filter will be reduced in hard water areas (and should be
replaced more frequently), or extended in soft water areas where scale is less of a problem.
-With the required filter 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.

6
TO RESET AND CONFRIM SEETING;…Press & hold button, screen will go blank but continue to hold, until
‘READY’ message is displayed on a RED screen.
If in doubt as to the hardness of water supplied in your area, consult your local water authority or Instanta Technical
Support.
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 the fitting of and regular replacement of a scale
reduction filter. (eg. AQ35 available from Instanta Spares)
To de-scale:
-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.
-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.
