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.
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
very hot, particularly the tap body. Care must be taken to
avoid injury, a burn or scald.
Commissioning
Note: pre- 01/06/02 Cascade boilers had slightly different modes
of operation, please contact Calomax for details.
Turn on the water supply and then switch on the electrical supply.
Ensure that the On/Off switch is in the On position. (Located at the
rear)
The Wait/Ready light will flash yellow (indicating below temperature)
and the unit will slowly fill with water (1.2 L/Min). When water passes
the low level sensor (just below tap level) the element will also be
energised. When the normal operating water level is reached the
Page 6
solenoid will be disabled and the element will continue to heat the
boiler until full operating temperature has been reached. At this point
the Wait/Ready light will show solid orange indicating that the boiler is
full and up to temperature.
Subsequent Use
After the boiler has finished the commissioning cycle, and water is
drawn from the tap, 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
(Re-setting commission mode). In normal use the boiler will always be
at operating temperature indicated by the Wait/Ready light showing a
solid (not flashing) colour. When the boiler is full and ready the light will
be orange and when the boiler is only part full the light will be yellow.
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.
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 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 Cascade 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,
check for scale inside the boiling chamber. The production of scale is a
