Automatic-Fill Water Boiler
USER INSTRUCTION
MANUAL

1.0 - INTRODUCTION
Your new Water Boiler is designed to give years of trouble-free service provided that the
instructions contained in this manual are followed.
All new series Instanta products are energy efficient, simple to operate and easy to service.
2.0 - WARNINGS & PRECAUTIONS
Please read the following carefully before starting work on this equipment.
A competent installation engineer should install this appliance in accordance with the
installation instructions for this appliance and all relevant local and national standards
including the following:
. Health and Safety at Works Act
. IEE regulations
. Local and national building regulations
. BS Codes of practice
. Water supply regulations
All personnel must be provided with sufficient and appropriate training in the safe use of this
appliance.
In line with Health and Safety requirements we recommend that a risk assessment be carried
out after the boiler has been installed.
A warning notice displayed next to the machine is often helpful in notifying users that the
appliance contains and dispenses near boiling water.
During normal use of the boiler, certain surfaces will become hot (especially the draw off
tap(s)). Care should be taken to avoid potential injury from burns and scalding whilst
operating this appliance.
Scale formation within the hot water appliances can be problematic in hard water areas.
Damage to the appliance caused by excessive scale build up may invalidate the warranty. See
notes on de-scaling.
Drawings, parts lists, circuit/wiring diagrams are the sole property of Instanta Limited and
must not be reproduced with consent.
3.0 - CHECK LIST
Before starting installation check that you have the following parts:
1. Drip Tray
2. Drip tray drain-kit
3. Food-quality flexible hose (3/4”bsp)
4. Instruction booklet

4.0 - INSTALLATION
a) WATER CONNECTION
Connect the WRAS approved hose (supplied) to the back of the boiler and the other end to the
mains water supply, via an accessible isolating tap with a ¾”BSP thread.
The hose supplied with the machine is manufactured from materials which have been approved for drinking water.
Do not use washing machine hoses (usually red, black or blue) as they are not suitable for drinking water and will
cause a bad taste.
The water supply must have a pressure not exceeding 7 bar (96psi), and no lower than 2 bar
(28psi).
If your water pressure exceeds 7-bar, fit a suitable pressure reduction valve.
INSTANTA CANNOT BE HELD RESPONSIBLE FOR ANY MACHINE MALFUNCTION IF THE WATER
PRESSURE EXCEEDS THAT STATED. IF IN DOUBT, CONSULT YOUR WATER SUPPLY COMPANY.
Water purification filters are available to ensure fresh water. Also, scale reduction filters are
available for hard water areas. Fitting a scale reducer will help minimise scale but will not
eliminate scale completely. Please contact Instanta Spares Department 01704 502905) for
details.
b) 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.
Whilst 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.
c) ELECTRICAL CONNECTION
Your machine is supplied with a standard 3-pin bonded plug and lead with 13amp fuse.
5.0 - OPERATION
SWITCHING BOILER ON FOR THE FIRST TIME:
After the electrical and water connections have been made, the boiler is ready to be used.
- Switch on machine - 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. (on initial prime, wait 10 minutes before drawing water)

6.0 - IN 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(s) on the front of the boiler (CAUTION: Take care as
boiler dispenses near-boiling water).
7.0 - CLEANING
Clean the external surfaces of the boiler with a damp cloth to maintain hygiene. Do not use
abrasive material on the outer surface of the machine. Wipe the draw-off tap daily to remove
any lime-scale deposits and check that the outlet is clear.
TO CLEAN THE PROBES:
- Disconnect machine from the power supply.
- Lift off outer-lid. After removing the lid the tank is accessible.
- Remove the tank lid by taking out the fixing screws.
- Lift out the baffle plates on the inside of the tank (note the position of these plates so that you
can replace them correctly).
- Wipe clean the level sensing probes using a non-metallic scourer. It is important to ensure that
you also clean the white insulators.
- Reassemble and switch the boiler back on.
8.0 - MAINTENANCE
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.
Draw-Off Tap: The draw-off tap components are subject to wear & tear. We strongly
recommend that the tap is inspected periodically (at least once a year as part of a general
maintenance routine). It is advisable to keep a spare tap spring and washer in case of
emergencies.
Spare parts and accessories are available from Instanta Limited –Tel: [phone]
DE-SCALING:
- Disconnect machine from the power supply,
- Empty the machine through the draw off tap and allow too cool down.
- Lift off the outer-lid. After removing the lid the tank is accessible.
- Remove the tank lid by taking out the four fixing screws.
- Lift out the baffle plates on the inside of the tank.
- Remove as much scale as possible by hand. Any scale which is difficult to remove can be
dissolved by using a solution of de-scaler.
- Wipe clean the level sensing probes.
- Ensure all traces of de-scaler are removed before using the boiler again.
9.0 - SERVICE WARNINGS AND FAULT DIAGNOSIS
Your boiler is fitted with an intelligent fault diagnosing system and is able to detect the fault
conditions below:
1 Flashing Green - The bottom probe is scaled up
2 Flashing Orange - The water supply is off
3 Flashing Red - An internal component has failed. Contact Instanta
Service Department –01704 502911
4 Flashing Red & Green - As 3 above

10.0 –FAULT FINDING
The majority of possible faults have been covered previously. However, in certain
circumstances, safely controls within the boiler may be activated.
There are two safety over-heat cut-outs in your boiler.
1). Over-boil safety cut-out –this will be activated should the boiler produce excess steam.
This can be due to;
- lime-scale within the tank,
- a temporary interruption in the water supply.
- a faulty temperature sensor.
To reset boiler, switch off at the mains power supply and allow the boiler to cool for ten
minutes before switching back on.
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.
To reset boiler, Isolate from mains power supply. Remove the back panel and push the small
red reset button in the element cut-out.
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
11.0 - GUARANTEE
Your boiler is guaranteed for twelve months from date of installation. In the event of a
problem arising during the guarantee period please contact the Instanta Service Department
quoting the Model type and Serial Number and the fault description. Failure to quote the
serial number may result in delays
Our guarantee includes on site labour and parts for problems caused by fault of manufacture
and component failure with the following exclusions:
1Problems caused by hard water and lime scale. We regret that we cannot be held
responsible for problems caused by hard water
2 Dripping Taps. These components are subject to wear and tear but in the event of a
tap failing within twelve months of installation, we will be pleased to replace the tap
assembly by post. Fitting is very simple and requires no tools. An engineer call out is
not necessary.
