Trouble Shooting

Principle. An electronic ballast (choke) provides the correct voltage and current for
the lamp. The circuit board monitors the current to the lamp and if it is not present,
illuminates the red alarm light and sounds the alarm buzzer (a "squealing" noise).
An orange light indicates the power is on.

WARNING: When servicing or attending your Steriflo
ensure power is switched off and lead unplugged. Electrical
connections should be serviced only by qualified persons. If any
electrical supply lead is damaged, it must only be replaced by an
electrically qualified person.
Care should also be taken when servicing or disassembling the
unit and associated pipework to avoid possible injury from
pressurised water. Unplug power, relieve pressure by opening a
tap on the discharge side of the unit and allow any water in the
unit to cool before attempting to dismantle.
