B. Boiler temperature adjustment
See chapter 4 page 2 (Programming - Installation sub-menu).
C. Heating element replacement
The heating element is part of the boiler assembly. It cannot be replaced as a separate item in the
field. Rather than disassembling the heating element separately the boiler is replaced as a
single assembly (See boiler replacement on page 1).
The dry running safety device is integrated in the heating element connector.
It consists of two components:
(1) A bi-metal plate that switches the heating element off when the temperature becomes too
high.
(2) A plastic pin that will melt to disconnect the power supply to the heating element in case the
bi-metal does not function properly. (back-up safety)
The heating element or the boiler should be discarded if this safety device has been actuated.
To remove the heating element from the boiler:
1. Remove the boiler lid (4 screws).
2. Remove the retaining screws of the heating element.
3. Take the heating element out of the boiler.
The heating element itself can be very hot!
Be careful and take proper measures when handling.
4. Reassemble in reverse order.
Make sure that the sealing ring between boiler and the heating element is correctly placed
when the heating element is being installed.
