Servicing should be carried out with the power switch off and the
chlorinator disconnected from the power point. Where is it absolutely
necessary to power the unit for service then it shall be powered from the
unearthed secondary of a safety isolation transformer or by means of an
approved earth leakage detection unit.
The chlorinator is a prescribed item under NSW law and cannot be
modified in any way.
As part of servicing the following safety checks need to be performed on
the chlorinator:
•
The interior of the unit has not been modified or tampered with
in any way.
•
There is adequate separation between mains and extra low
voltage parts.
•
All insulating panels are in place and terminal connections are
tight.
•
Earth pin of power cord to all external metal parts of the
chlorinator to have a resistance value not exceeding 0.1ohm.
•
Megger power cord active and neutral at 500 V D.C. to all
external metal work and output cell terminals in turn.
Resistance value not to be less than 2 meg ohm.
•
Visually ensure that all parts of the unit are in good condition.
Insulation on power cords is in good condition and any
corrosion on the pins of the power cord plug to be rectified.
Place a sticker on the underside of the unit identifying the Company that
carried out the service, date of service, safety check carried out and the
signature of the service technician that carried out the work.
