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 fl oor 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 qualifi ed engineer must
install this unit. Plumbing and electrical installation work may be
involved.

To comply with the U.K. Water Supply Regulation a single check­valve must be fi tted 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 where provided, or rigid 15mm pipe in
a manner which complies with UK water regulations 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 fi ne mesh “in line” water fi lter is fi tted in the
pipe work. Failures due to scale and sediment are not covered by
the warranty.

directly connected to a closed waste, as taste problems may occur and
should never be allowed to become blocked or restricted.15mm copper or
‘Speedfi t’ pipe should be used. The drip tray kit provided with the counter
top models allow the option of plumbing the overfl ow 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 overfi ll pipe
being extended as advised, any subsequent damage incurred will be the
responsibility of the installer.

CLEANING

Avoid using any abrasive materials. Wiping the outer casing
with a damp cloth should be suffi cient. 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 qualifi ed engineer.

The Eclipse boiler benefi ts 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
fi rst 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-fi lling.

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

• To stop fi lling, release the handle so it returns to the closed
position.

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 fi tted by a suitably qualifi ed
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 fi ll 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 fi ll 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 fi nished 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.

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.

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 fl ush 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 re­commissioning 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 fi lling with water to the level of the draw-off tap before
switching on the electrical supply to the boiler.

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 fi rst reinstating the water supply.

If the unit requires servicing the red service indicator will fl ash 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-fi lled 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 fl ush 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 fi lter.
The unit can be used normally while the service indicator is fl ashing
a 4x pulse. For further assistance, contact our service department
on 0113 249 6681 e-mail [e-mail]. or fi nd 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.

General function

The printed circuit board (PCB) controls the heating and fi lling
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.

In addition, the Eclipse range of boilers carry an additional
12 month back to base warranty.

Some factors are beyond our control and would invalidate the
warranty offered. These include:
Incorrect installation
High / Low water pressure
Incorrect voltage supply
Accidental damage
Limescale build-up
The last item can be a particular problem for water dispensing

equipment in hard-water areas. All hot water equipment should be
serviced and de-scaled by approved organisations on a regular
basis to avoid a damaging build-up of limescale.

Although our boilers incorporate scale-inhibitor technology, we
recommend that a taste, odour and scale fi lter should be fi tted
where appropriate.
