9.8 Printed Circuit Board replacement (PCB)
In the 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.
9.9 Adjusting the Water Temperature Set Point
The temperature potentiometer (Pot) is pre-set at Heatrae Sadia and
will only require adjustment in exceptional circumstances. Contact
Heatrae Sadia 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
causing the unit to trip the overheat cut-out device.
9.10 On / Off Switch
The On / Off switch is positioned at the rear of the machine. When
in the off position the unit will cease to function & the light on the
fascia will go out.
NOTE: This switch must not be used to isolate the electrical supply for
servicing / maintenance. When maintaining / servicing the unit the
power cord must be removed from the mains supply.
