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 check­valve 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.

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 (Re­setting 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.
