LOCATION
To comply with recommendations
from the health and safety executive
it is important that due consideration
be given to safe operation of the
controls of the boiler. The boiler
should therefore be mounted in such
a manner that the operator can stand
directly facing the machine with the
controls at a recommended height
from the floor of 1200mm +/- 100mm.
Consideration should also be given
to the servicing requirements of the
machine. The maximum and minimum
ambient operating conditions must be between 5 °C and 35 °C.
The appliance is not suitable for installation where a water jet
could be used. Install the boiler on a surface suitable for near
boiling temperatures and the working weight of the boiler. Allow
adequate clearance for ventiation and for the easy removal of
the outer casing lid and rear panel. Calomax ltd recommend a
minimum clearance of 50mm on all sides of the boiler A suitably
qualified engineer must install this unit. Plumbing and electrical
installation work is involved.
INSTALLATION
All metalic components of the machine, in direct contact with
drinking water are manufactured from high quality 304 grade
stainless steel, or non ferrous materials, providing maximum
resistance to corrosion.
CONSTRUCTION
The boiler must be installed in a location where access is
restricted to operators that are suitably trained, or where
untrained operators of the machine can be supervised by trained
personnel.

COLD WATER INLET
To comply with the U.K. Water Supply Regulation a single check-
valve must be fitted to the supply. BEFORE CONNECTING, THE
SUPPLY PIPE MUST BE THOROUGHLY FLUSHED OUT TO
ENSURE THAT FOREIGN MATTER DOES NOT BLOCK OR
ENTER THE SOLENOID VALVE
The boiler must be connected to a potable water supply using the
food grade hose provided, in a manner which complies with UK
water regulations. The hose should be connected to a ½” (15mm)
drinking water supply via an appropriate isolating valve. The
supply must provide a constant pressure of between 20 KPa and
1000 KPa (0.2 to 10 Bar).
If the water supply contains excessive solids in suspension it is
recommended that a fine mesh “in line” water filter is fitted in the
pipe work after the stop cock. Failures due to scale and sediment
are not covered by the warranty.

ELECTRICAL CONNECTIONS
The boiler is supplied with a fitted plug and lead and should be plugged
into a 240v 13A electrical socket, capable of carrying a load of 3kW. The
installation of a residual current device (RCD) having a rated residual
operating current not exceeding 30 mA is advisable.
USER INSTRUCTIONS
During normal operation some external parts will become
hot. Care must be taken to avoid injury, a burn or scald.
Commissioning
1. Turn water supply on
2. Turn electrical supply on
On initial switch-on only
After a few seconds delay for the electronics to charge up, the boiler will
begin filling with water and the ‘Ready’ light will flash to indicate wait. If the
key switch is in the ‘on’ position the push button will flash to indicate wait,
at this point the button is disabled. When water reaches the low level sensor
(element covered) the element will be energised as well as the solenoid.
When the selected operating level is reached the solenoid will turn off and
the element will remain on until full operating temperature is reached.
With the key switch in the ‘ON’ position the push button will stop flashing
and show solid colour when the boiler is up to full temperature and the
button will be enabled, at this point the ‘ Ready’ light will stop flashing and
show solid colour and the ‘Full’ light will also be illuminated.
VENT & OVERFLOW
The vent / overflow pipe must be extended and laid with a continuous
fall, discharging to a safe and visible point. The pipe should not be directly
connected to a closed waste, as taste problems may occur and should
never be allowed to become blocked or restricted. One way this could
be connected is via a tundish arrangement. 15mm copper or ‘Speedfit’
pipe should be used. If the machine is operated without the overfill pipe
being extended as advised, any subsequent damage incurred will be the
responsibility of the installer.

Page 7
On subsequent operation of the boiler
The boiler will fill and heat in cycles. It will allow only a limited amount of
water to enter the unit at any one time and then switch off the solenoid and
energise the element.
Note:
When the green service indicator light on the front of the boiler is showing
solid colour, the machine has been starved of water for in excess of 20
minutes and the solenoid valve has been disabled to prevent damage to the
solenoid coil through overheat. To re-energise the solenoid, the unit must
be disconnected from the electrical supply and then switched back on, after
first reinstating the water supply.
Subsequent Use
After the boiler has finished the commissioning cycle, and water is drawn
from the dispense valve, water will be replaced in short cycles (Small
amount of water and then heat) the solenoid and element will never be
on at the same time unless the boiler is switched off and on again (Re-
setting commission mode). In normal use the boiler will always be at
operating temperature indicated by the Ready light showing a solid (not
flashing) colour. When the boiler is full and ready the Full light will also
be illuminated. When the key switch is turned on the dispense button will
illuminate with solid colour to indicate water is available.
e Energy saving system
When the energy saving button is pressed and illuminated, the normal
operating capacity of the boiler is reduced from 9 litres to 5 litres, with a
subsequent reduction in energy consumption to maintain the lower volume
of stored boiling water. This is recommended for use at off-peak periods
when demand is low.
SCALE
The production of scale is a natural phenomenon and commonly occurs
in hot water systems. The nature of the scale produced and its rate of
formation varies widely throughout the country.
To ensure continuous, reliable operation, the boiler should be regularly
de-scaled by a suitably qualified engineer. Suitable chemical de-scalants
must only be used if the manufacturers recommendations are strictly

Page 8
• hold a cup below the dispense valve or place large vessels on the
drip tray. Care must be taken to avoid injury through splashing or
over-filling.
• To begin filling, enable the dispense valve by turning on the key
switch (button will illuminate). Pressing the dispense button will
allow water to flow from the valve.
• To stop filling, release the dispense button.
NEVER PASS YOUR HAND BENEATH THE NOZZLE.
• Please retain these instructions for future reference
• Ensure that a suitable drip tray is positioned below the dispense
valve. This will help keep the surrounding work surfaces and floor
free from drips or splashes. Various options are available and are
outlined on the Accessories page of this booklet.
• All de-scaling and servicing must be performed by a suitably
qualified engineer.
GENERAL NOTES
GENERAL OPERATION
adhered to. This is to prevent health and safety issues, taste problems
and potential damage to the appliance. Misuse of such chemicals is not
covered by the product warranty.
The Quantum-e boiler benefits from an integral scale inhibitor, this is not
a scale eliminator and its effects will differ according to the water quality
in your area. To ensure trouble free operation, periodically check for
scale inside the boiling chamber. The production of scale is a natural
phenomenon and some de-scaling may be required within the first 12
months. This is not covered under the products warranty as it is not a
fault. If the water supply contains excessive solids in suspension it is
recommended that a fine mesh “in line” water filter is fitted in the pipe
work after the stop cock.
CLEANING
Avoid using any abrasive materials. Wiping the outer casing
with a damp cloth should be sufficient. Some stainless steel
cleaning products may not be suitable for plastic and must not
come in contact with the plastic fascia. Always disconnect the
electrical supply before cleaning.
NEVER USE A SPRAY JET OR ANY OTHER METHOD WHICH COULD
CAUSE WATER TO ENTER THE ELECTRICAL CHAMBER.

If the unit requires servicing the service indicator will flash a sequence
of light pulses . A 2x or 3x-light pulse generally indicates that the low
or normal level probes require de-scaling.
A 4x-light pulse means the water level has reached the high level
sensor and the likelihood is that the energy saving or normal level
sensor requires de-scaling, or the machine has over-filled due to debris
trapped in the solenoid valve. The debris can be removed by drawing
plenty of water from the dispense valve, causing the solenoid valve to
operate and flush out the obstruction. The machine will reset itself once
the problem has cleared. If this does not rectify the problem, turn off
the water supply and remove the flexible hose to check for debris in the
valve’s filter. The unit can be used normally while the service indicator
is flashing a 4x pulse. For further assistance, contact our service
department on 0113 249 6681 e-mail [email protected]. or find
a local service engineer at www.calomax.co.uk
Note:
When the green service indicator light on the front of the boiler is showing
solid colour, the machine has been starved of water for in excess of 20
minutes and the solenoid valve has been disabled to prevent damage to the
solenoid coil through overheat. To re-energise the solenoid, the unit must
be disconnected from the electrical supply and then switched back on, after
first reinstating the water supply.
Once the outer casing is removed, access to the Service Area has
been gained. This access must be restricted to persons having
knowledge and practical experience of the appliance, in particular
as far as safety and hygiene are concerned.
De-scale
To gain access to internal components, the body lid must
be removed. The lid incorporates a condenser mechanism

which must be fitted the correct way round. The lid is labelled
accordingly. To remove the lid, break the lid gasket seal and pull
the lid forward and up, to the front of the machine before lifting it
clear of the body.
Note: Whenever the body lid has been removed from the boiler a new
lid gasket may be required to ensure a steam-tight joint. Damage to the
unit caused by a poor lid seal is not covered by warranty.
Scale deposits should be removed from all internal surfaces,
particularly the heating element, thermistor and level sensors by
gently tapping or scraping. If the deposits are soft, use a nylon
pad and flush out. Abrasive cleaning materials containing scouring
powders and detergents must not be used, such materials can
cause taste problems.
Suitable chemical de-scalants must only be used in accordance
with the manufacturers recommendations. This will prevent health
and safety issues, taste problems and potential damage to the
appliance. All trace of these chemicals must be removed from
the appliance before re-commissioning the unit . Misuse of such
chemicals is not covered by the product warranty.
IMPORTANT Before re-commissioning the boiler it is important
that all scale and moisture is removed from the level sensor
insulating gaskets, to avoid a false signal being transmitted
through the scale to the boiler body. Failure to remove this
scale and/or moisture could cause the sensor to indicate to the
PCB that water is covering the element, whether or not water
is present. In this situation the PCB could energise the element
causing failure. If in doubt, protect the element by hand filling
with water to the level of the draw-off tap before switching on
the electrical supply to the boiler.
General function
The printed circuit board (PCB) controls the heating and filling
functions of the boiler by monitoring the thermistor and level

Page 15
sensors. The PCB also controls the external light unit to indicate
the current state of the boiler. Red and yellow LED’S on the circuit
board indicate whether the PCB has energised the element or
solenoid respectively.
The auxiliary PCB controls the dispense valve, push buttons and
key switch functions.
Should an element fail and need to be replaced, it may be
necessary to replace the lid gasket to ensure a reliable steam-tight
seal. Note: the element has a permanent ‘Live’ feed, and the
‘Neutral’ is switched.
Printed Circuit Board replacement (PCB)
In the event of a PCB failing and a replacement being required, full
instructions will be supplied. It is important to note however, that the
Triac PCB must be securely mounted against the copper heat-sink
to ensure reliable heat dissipation. Heat transfer compound is also
supplied with all replacement circuit boards.
Adjusting the Water Temperature Set Point
The temperature potentiometer (Pot) is pre-set at Calomax and
will only require adjustment in exceptional circumstances. Contact
Calomax for advice.
Water boils at different temperatures depending on barometric
pressure. The temperature should not be tuned higher than 98°C, or
over boiling may occur during low barometric pressure conditions,
causing the unit to trip the overheat cut-out device.
