LOCATION

INSTALLATION AND MAINTENANCE

All metallic components of the machine, in direct contact with drinking
water are manufactured from high quality 316 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 positioned 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 +/- 200mm.

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.

Consideration should also be given to the servicing requirements of the
machine and individual user requirements must always be taken into
account. The minimum and maximum ambient operating conditions
are 5 °C and 35 °C respectively. The appliance is not suitable for
installation where a water jet could be used. Install the boiler on a
surface 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 recommend a minimum clearance of 50mm on
all sides of the boiler. A suitably qualified engineer should install this
unit. Plumbing and electrical installation work may be involved.

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.

TO COMPLY WITH UK 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 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. Do not reuse old hoses. Do not use red or
blue washing machine hoses as these will impart an unpleasant taste
to the water. The water supply must provide a constant pressure of
between 20 KPa and 1000 KPa (0.2 to 10 Bar).
If the water supply contains solids in suspension it is recommended
that an “in line” water filter is fitted in the pipe work. Problems caused
by scale and sediment are not covered by the warranty.

ACCESS INSTRUCTIONS

Access to the internals of the machine is gained by the removal
of the front panel. It is advised to remove the cup stand drawer
before removing front panel. To remove the drawer pull the latch up
underneath the cup stand and slide the stand out. Calomax advise
to place the drawer back in its housing after the front panel has been
screwed back into place to avoid damage. When replacing the drawer
ensure there are no wires trapped behing the drawer to avoid pulling
them out.

VENT / OVERFLOW

The vent / overflow pipe should be extended and laid with a continuous
fall, discharging to a safe and visible point via either of the two

options advised: ‘Via the drip tray’ or ‘By-passing the drip tray’,
both options are shown on the opposite page. 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 installed without the vent / overflow pipe being
extended as advised, any subsequent damage incurred will be the
responsibility of the installer. Further information, including diagrams,
can be found under the ‘Installation Guide’ section on our website.

After removing the cup stand pull off the outercasing lid from its
mounting clips. Do not pull the cup rails as this may damage the lid.
Remove the top two panel mounting screws, the cover is fitted with
two more clips at the bottom of the panel which can be pulled off to
gain access to the internal workings of the boiler.

Via the drip tray

Remove the packaging cap and
replace the end stop on the back
of the drip tray with the straight
push fit connector supplied. Then
connect 15mm pipe to the other
end of the connector and run
it to a safe and visible point of
discharge.

The boiler will have a packaging cap on the
vent / overflow pipe underneath the boiler.
THIS MUST BE REMOVED.
Pull this off in the direction of the arrow.

VENT / OVERFLOW CONFIGURATION OPTIONS

By-passing the drip tray

Remove the packaging cap and
attach the elbow push fit connector
to the vent / overflow pipe on the
bottom of the boiler. Then connect
15mm pipe to the other end of the
connector and run it to a safe and
visible point of discharge.

Only authorised personnel who have been instructed in the safe and
proper use of the equipment should be allowed to use this machine.
Boiling water is discharged from the tap and due care and diligence
should be exercised at all times.
In the event of the power supply lead to the boiler becoming damaged,
the appliance must be removed from service. For 3kW models, a
replacement genuine part is available from Calomax which must be
fitted by a suitably qualified engineer in order to avoid a hazard.

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 at a flow rate of

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.

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 3kW models should be connected to a 240V ac 13A electrical
supply, via the fitted plug and lead.
The 6kW models require fixed wiring to the internal terminal block.
A means of disconnection must be provided in which at least 3mm
separation between the live and neutral poles of the supply exist.
The 6kW models require the connection of an external equipotential

The installation of a residual current device (RCD) having a rated
residual operating current not exceeding 30 mA is advisable.

bonding conductor. This is located on the tap bracket
inside the boiler, accessible when first installing the boiler.
It is indicated by the equipotential symbol.

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. Further information on scale, including a postcode
search facility for water hardness in your area can be found under the
‘Water Filter Advice’ section on our website.

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
volume 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 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
panel, the ‘Eco’ feature is selected. This feature reduces the working
capacity of the appliance by approximately half. The ‘Full’ light will be
disabled.

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.
