Electric shock

completely from all power sources, ensure that it

cannot be switched back on, and verify that it is

safely isolated from supply.

DANGER!

The housing of the high voltage unit may

not be opened or damaged as there are

parts inside it that are under high voltage.

Non-compliance with the above may

result in serious or fatal injuries.

DANGER!

Earthing of the boiler is required
