LOCATION
INSTALLATION AND MAINTENANCE
All metallic 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
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.
Calomax products have been tested and found
to comply with the requirements of the Water
Supply (Water Fittings) Regulations 1999
for England and Wales Water Bylaws 2000,
Scotland and the Water Regulations Ireland.
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 or wall
suitable for the working weight of the boiler. Allow clearance for
ventilation and for the easy removal of the outer casing lid and front
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 may be involved.

COLD WATER INLET
TO COMPLY WITH U.K. WATER SUPPLY
REGULATIONS A SINGLE CHECK VALVE MUST
BE FITTED. 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 where provided, or rigid 15mm pipe in a manner
which complies with UK water regulations via an appropriate
isolating valve. Always use the new hose supplied (counter-top
models only). Do not reuse old hoses. 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. Failures due to scale and sediment are not covered by
the warranty.
3 point fixing wall bracket
.for wall mounted range
Hang the boiler on the wall bracket
and secure into place with 4th fixing.
The electrical cable should be
routed as shown.
The use of 6mm Rawl-Bolts is
recommended to secure the
bracket to a wall of appropriate
construction to support the
working weight of the boiler.

ACCESS INSTRUCTIONS
Access to the internals of the machine is gained by the removal of
the front panel. Prise off the outercasing lid from its mounting clips.
remove the top two panel mounting screws, and the third bottom
mounting screw (where fitted). Remove the cover.
The 3C5C model does not have the third screw, it is fitted with two
more clips at the bottom of the panel which can be prised off.

Page 7
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. The drip tray kit provided with the counter
top models allow the option of plumbing the overflow pipe to discharge
into the drip tray and then plumbing the drip tray to a safe and visible
point of discharge. If the machine is operated without the overfill pipe
being extended as advised, any subsequent damage incurred will be the
responsibility of the installer.
If the boiler is required to
drip or overflow into the
drip tray, the configuration
of pipework may be altered
as follows. Remove the
machine front panel and
unclip the pipework elbow.
Carefully pull the elbow
in the direction of the
arrow, out of the silicone
connecting tube on the
end of the main water pipe.
The silicone connecting
tube will now direct water
into the drip tray.

This equipment is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible
for their safety.
Children should be supervised to ensure that they do not play with the
appliance
In the event of the power supply lead to the boiler becoming damaged,
the appliance must be removed from service. A replacement genuine part
is available from Calomax Ltd, and must be fitted by a suitably qualified
engineer
Commissioning
Turn on the water supply and then switch on the electrical supply.
When the power switch is pressed on the front fascia the Wait light
will illuminate and the unit will fill with water (1.3 L/Min). When water
reaches the low water level sensor, the element will be energised and
the solenoid will continue to fill the boiler to the normal operating water
level. When the water has reached the normal operating temperature,
the Wait light will extinguish and the ready light will illuminate. At this
time the full light will be illuminated indicating that the machine has
reached full capacity of boiling water.
Subsequent Use
After the boiler has finished the commissioning cycle, and water is
drawn from the tap, water will be replenished 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
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.
ELECTRICAL CONNECTIONS
The boiler should be connected to a 240v ac 13A electrical supply,
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.

Page 9
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 parts. 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.
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.
The Eclipse 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. De-scaling may be required within the
first 12 months. This is not covered under the product’s warranty as it is
not a fault.
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.
at operating temperature indicated by the Ready light being illuminated.
The full light will be illuminated only when the boiler is full of boiling
water. By pressing the symbol on the upper fascia label, the
economy feature is selected. This feature reduces the working capacity
of the appliance by approximately half.The full light will be disabled.

When the red service indicator light on the front of the boiler is
illuminated, the machine has been starved of water 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.
If the unit requires servicing the red 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 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 check for debris in the solenoid valve 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
Access to internal components can be gained by the removal
of the outer casing lid and front panel. 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.
SERVICE INSTRUCTIONS

De-scale
To gain access to internals of the water tank, the body lid must be
removed. Remove the 4 screws, break the lid gasket seal and lift 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 manufacturer’s recommendations. This will prevent health
and safety issues, taste problems and potential damage to the
appliance. All trace of these chemicals must be removed 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 sensors and insulating gaskets, to avoid a false signal
being transmitted through the scale to the boiler body. Failure
to remove this scale and/or moisture will 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 will 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.

Page 20
General function
The printed circuit board (PCB) controls the heating and filling
functions of the boiler by monitoring the thermistor and level
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.
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 unlikely 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.
