LOCATION

COLD WATER INLET

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

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 to the draw-off tap handle 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 left hand side panel panel. Calomax
ltd recommend a minimum clearance of 50mm on all sides of the boiler
except the left hand side which requires minimum fo 150 mm clearance
for maintenance. A suitably qualified engineer must install this unit.
Plumbing and electrical installation work is involved.

To comply with the U.K. Water Supply Regulation a single check-

valve

must be fitted to the supply.

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.

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

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.15mm copper
or ‘Speedfit’ pipe should be used. If the machine is operated without

ELECTRICAL CONNECTIONS

Kudos6 Dual-flow boilers require fixed wiring to the rear terminal block.
A means of disconnection must be provided in which at least 3mm
seperation between the live and neutral poles of the supply exists.

Kudos9 Dual-flow boilers require fixed wiring to a 3 phase 4 wire supply in
which at least 3mm seperation exists in the three phases of the supply (but
not the neutral).

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
very hot, particularly the tap body. Care must be taken to
avoid injury, a burn or scald.

Commissioning

Turn on the water supply and then switch on the electrical supply.
The Wait/Ready light will flash yellow and the unit will pulse with water
(8L/Min). When water reaches the normal operating level sensor, the
solenoid will be disabled and the element will be energised. When a
band of water around the draw off tap has reached the normal operating
temperature, the Wait/Ready light will show solid yellow colour (indicating
water available). The elements will remain energised until the full capacity
has reached normal operating temperature, indicated by the wait/ready
light turning to solid a orange colour.

Subsequent Use

After the boiler has finished the commissioning cycle and water is drawn
from the tap, water will be replaced in pulses automatically by the solenoid

the overfill pipe being extended as advised, any subsequent damage
incurred will be the responsibility of the installer.

Page 7

The element(s) may be also be energized at the same time. If water is
drawn from the machine but boiling water is still available, the Wait/Ready
light will be illuminated solid yellow. If full draw off capacity is removed the
boiler may cool, indicated by the Wait/Ready light flashing yellow.

Note:

When the green service indicator light on the front of the boiler is showing
solid colour, the header tank sensor has been starved of water for in
excess of 30 seconds and the bottom thermistor has been disabled. To
reinstate normal operation the water supply needs to be re-applied.

If the service indicator light flashes, this indicates that the water level has
reached the high level sensor and the likelihood is that the 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 tap, 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. When the
service light is flashing, the element is disabled and the boiler may cool.

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 de­scaled by a suitably qualified engineer. Suitable chemical de-scalants must
only be used if the manufacturers recommendations are strictly 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 Kudos range of boilers benefit 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.

GENERAL

NOTES

GENERAL OPERATION

• Hold a cup below the tap or place large vessels on the drip tray.
Care must be taken to avoid injury through splashing or over-filling.

• To begin filling, pull the handle forward or push it backward – hot
water begins to flow. If the tap is opened fully it can be locked open
(for filling large vessels) in this state the boiler must never be left
unattended.

• To stop filling, release the handle so it returns to the closed
position. AS STANDARD THIS BOILER IS FITTED WITH
AN EXTENDED NOZZLE DESIGNED FOR FILLING LARGE
VESSELS. DUE TO THIS, WATER WILL CONTINUE TO FLOW
FOR SEVERAL SECONDS AFTER THE TAP HAS BEEN
CLOSED NEVER PASS YOUR HAND BENEATH THE NOZZLE.

• Please retain these instructions for future reference

• Ensure that a suitable drip tray is positioned below the tap nozzle.

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 (page 9).

• All de-scaling and servicing must be performed by a suitably
qualified engineer.

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.
