Warning: this appliance must be earthed.
Following remedial service the earthing continuity of the heater must be
checked by a qualified technician using an appliance tester, or continuity tester
of accuracy Class 5 or better. Class 5 denotes an accuracy of 5% full scale
deflection.
1. Isolate power supply.
2. Set meter to 0 ohm with leads connected together.
3. Connect one test lead to the earth pin on the three pin plug.
4. Connect the other test lead to a bare patch of metal (preferably on the edge)
of the top of the cover, then to the front cover of the unit, and then to the metal
part of the tap.
Warning-
the water may be boiling - show extra care.
5. Test that in every instance the electrical resistance does not exceed 1 ohm.
Earthing Continuity Verification
If required, an earth continuity test can be
performed by testing between the earth pin on
the products lead and a exposed piece of metal
on the case and the tap body.
