ELECTRICAL CONNECTIONS
Cascade-6A boilers require xed wiring to the rear terminal block.
A means of disconnection must be provided in which at least 3mm
separation between the live and neutral poles of the supply exists.
( Double pole isolating switch ).
The installation of a residual current device (RCD) having a rated
residual operating current not exceeding 30 mA is advisable.
USER INSTRUCTIONS
Commissioning
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.
Turn on the water supply and then switch on the electrical supply.
The Wait/Ready light will ash yellow (indicating below temperature)
and the unit will slowly ll with water (1.2 L/Min). When water passes
the low level sensor (just below tap level) the elements will also be
energized. When the normal operating water level is reached the
solenoid will be disabled and the elements 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.
VENT & OVERFLOW
The vent / over ow 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
‘Speed t’ pipe should be used.
Note
Although the machine will operate without this pipe being extended,
failure to do so will mean the surroundings are susceptible to damage
from any discharge
Subsequent Use
After the boiler has nished 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 elements 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 ashing) 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 rst reinstating the water supply.
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 quali ed engineer. Suitable chemical de-
scalants must only be used if the manufacturer’s 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-6A boiler bene 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. The production of scale is a
natural phenomenon and some de-scaling may be required within the
rst 12 months. This is not covered under the product’s warranty as it is
not a fault.
