INSTALLATION
a) POSITIONING THE UNIT
The heater should be positioned in a convenient place, on a wall that is capable of supporting it safely (refer
to Technical Specification above for weight of boiler). Use the mounting template and fitting kit provided.
Locate in an area where there is adequate space to use the boiler safely (e.g. free from risk of congestion
and tripping hazards).
Position the boiler so that the tap is approximately 400mm above a draining board. Leave sufficient space
around the unit to enable access for servicing, paying particular attention to the position of the top-centre
fixing screw that holds the case in place.
When mounting on wall…screw in the top two screws leaving about 6mm protruding and hang the machine
using the keyhole slots provided. Once the machine is positioned, tighten the top screws and insert the bottom
screw.
Do not block ventilation holes in boiler case
b) ELECTRICAL CONNECTION
The circuit should be protected by its own 13amp double-pole connection unit with flex outlet to BS5733,
alternatively the circuit should have a means of disconnection incorporated in fixed wiring, having a contact
separation of at least 3mm in all poles. Minimum cable size is 1.5mm2. The use of an ELCB is recommended.
- WARNING: This appliance must be earthed.
- Electrical installation should conform to current I.E.E. wiring regulations.
- When using fixed wiring, the bare section of earth must be sleeved to within 8mm of the end.
- Only a qualified electrician should carry out this work.
BASE ENTRY OF CABLE: Use the cable gland. Loosen cable-gripping nut and pass cable through gland, leaving
enough free cable to connect to terminal block. Tighten cable gland grip nut.
Alternative Rear Entry Installation (Electrical): The fixed or flexible cable is connected direct to the terminal block –the cable gland is
not utilised.
DO NOT SWITCH ON UNTIL THE INSTALLATION IS COMPLETE AND THE CASE IS IN PLACE

c) WATER CONNECTION
NOTE: Although it will not harm the boiler, it should not be operated with the water supply turned off.
- Water supply must have a pressure not exceeding 7 bar and no lower than 2 bar. (If the mains water
pressure is below 2 bar a fault situation could arise)
- If water pressure exceeds 7 bar a suitable water pressure reducing valve will need to be fitted to the
water supply to bring it to a level that the machine can cope with. Failure to do so could result in the
boiler overfilling.
THE MANUFACTURERS CANNOT BE HELD RESPONSIBLE FOR ANY MACHINE MALFUNCTION IF THE WATER PRESSURE IS NOT WITHIN THE RANGE
STATED. IF IN DOUBT, CONSULT YOUR WATER SUPPLY COMPANY.
Connect to a suitable cold water drinking supply as below;
- Fit the 15mm push-fit coupling onto the water inlet solenoid pipe and connect to cold water mains
supply using 15mm copper pipe.
NOTE: If micro-bore pipe is used instead of copper pipe, the size must be minimum OD 3/8” (10mm).
- A 15mm stop valve must be fitted between the water supply and the boiler so that it can be isolated.
Water purification filters are available from Instanta to ensure fresh tasting water. In hard water areas,
scale can cause problems. Fitting a scale reducer will help minimise scale but will not eliminate scale
completely.
NOTE: To avoid damage to the appliance, do not use any solder connections whilst pipes are connected to the
boiler.
Alternative Rear Entry Installation (Water Connection): Replace 15mm straight push-fit coupling (supplied) with a 15mm
push-fit elbow. Push firmly onto the inlet solenoid pipe with the elbow facing the wall. Push the 15mm cold water supply
firmly into the elbow.
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 strongly recommend that the water is tested
regularly.
If you have any queries in this respect, please contact our customer services team.
d) OVERFLOW / DRAIN
The fitting kit includes a 15mm, straight push-fit coupling with a small piece of 15mm copper pipe pushed into
it. This connector must be pushed onto the corresponding brass overflow connection on the services-bracket
(alongside the solenoid).
If the overflow is to be extended, remove the copper pipe (supplied) and replace with 15mm pipe of your
chosen length. The pipe must have a continuous fall and should not be longer than 300mm (if a longer run is
required, use 22mm pipe to avoid airlocks. The overflow pipe should have no more than four right angle bends
and should discharge to a safe, visible position.
Alternative Rear Entry Installation (Overflow/Drain): If rear entry has been chosen, the straight push-on coupling must be replaced
with a 15mm push-fit elbow (available from plumber’s merchants). Push the elbow onto the brass overflow connection on the services-
bracket (alongside the solenoid). As described above, the pipe must have a continuous fall etc.
Under certain conditions the overflow pipe could vent steam, hot water or cold water and the manufacturers cannot
be held responsible should damage occur from such discharge if the overflow pipe has not been directed to a suitable
position where overflowing water can run away safely.

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.
VENT PIPE:
A small silicone rubber tube connects the tank-lid to the back panel. Ensure this is connected (and hasn’t come
off in transit) and that the outlet fitting in the back-panel is not obstructed.
e) FITTING CASE:
- Attach the Earth wire connection to bottom of stainless steel boiler-case using M4 screw & washer
supplied.
- Offer up the case to the wall-mounted boiler and plug-in the two communications-leads (from circuit
board to LCD screen and from circuit board to push-button) located on inside of boiler-case.
- With the communications leads and Earth wire connected, carefully position the boiler case onto the
wall-mounted boiler chassis, ensuring that the water-valve outlet pipe locates into the slot-opening in
the plastic cup aperture.
- Secure case in position using M4 screw (supplied) at top and bottom of the case.
**********************************************************

OPERATION
First use (once water and electrical connections have been made);
- Switch the power and water supply on. 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 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 push button will illuminate Red.
- 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 is always at the correct temperature).
IMPORTANT NOTE: In normal daily use, the boiler may be used as soon as the READY indicator comes on, but
on first install, wait 15 minutes before starting to use.
- The boiler is now ready for use.
- Hold cup/teapot under water outlet and press & hold the Red illuminated button to dispense hot
water. “CAUTION BOILING WATER” message will flash 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:
OPTIONAL “TIMED” DISPENSE:
This function is appropriate when the cup/teapot being filled is always the same size/capacity.
To change boiler from “on-demand” default setting to “Timed” dispense:
1) Switch off on front of unit
2) Isolate from mains power supply and wait 10 seconds.
3) Switch boiler back on and at the same time, press & hold the dispense button for 5 seconds.
Boiler will either start to fill with water or the dispense button will begin to flash (depending on
water level in tank).
4) Hold vessel under dispense outlet
5) Press & hold the dispense button to fill 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).
6) 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).
7) To continue, switch boiler back on by pressing the ON/OFF button again.
8) 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 flash 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 flashing, the top-up facility ends and the boiler reverts
back to timed dispense mode.
To change back from “Timed” to standard “on-demand” dispense:
•Follow steps 1 to 4 (as above) then; …
•Press dispense button very briefly (for less than 1½ seconds), to activate the “on-demand” function
again.
•Press ON/OFF button (below display) to save the new setting (boiler will go into standby mode).
•To continue, switch boiler back on again by pressing the ON/OFF button. The boiler will now
dispense for as long as the button is pressed.

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.
OPTIONAL CUP-SUPPORT BRACKET & SPILL-TRAY KIT
An optional CUP-SUPPORT BRACKET & SPILL-TRAY KIT for the WMS6PB is available from Instanta Spares
department (Part No: DBST1/KIT). This support bracket attaches to the underside of the boiler-case allowing
vessels to be placed onto a spill-tray, located beneath the cup recess. This removes the necessity of holding
the cup/teapot by hand when filling.
FILTER COUNTER (Optional if a filter or softener has been fitted):
If an external filter/softener is fitted to the unit there is an optional filter-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 filter when required. Note: This counter is set to ‘Off’ as standard.
To enable filter-counter, proceed as follows:
-Turn machine off on front panel.
-Press & hold “on/off” 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
filter symbol” (default filter setting).
-Press button (short push) to scroll between the different filter settings;
SOFT (13001 litres)
MEDIUM (9001 litres)
HARD (6001 litres)
EMPTY FILTER SYMBOL (No Filter counter)
-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.
-TO RE-SET & CONFIRM NEW SETTINGS; …Press & hold button, screen will go blank but continue to

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.
To de-scale:
-Isolate machine from power supply and allow to cool
-Remove the boiler case (2 screws)
-Remove tank-lid (four fixing screws). The tank is now accessible.
-Lift out the evaporation plates (inside of tank –Remember order of removal).
-Empty water from tank via removable drain plug (Remember to refit drain plug).
-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
boiler again.
-Replace evaporation plates, tank-lid and boiler case.
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, isolate the machine at the mains supply and then switch back on after 10 minutes.
If the fault does not clear, call technical support for advice.
