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 tap
top under the plastic paddle. This can be achieved by inserting the probe up
from behind the paddle without losing water.
Warning-
the water may be boiling - show extra care.
5. Test that in every instance the electrical resistance does not exceed 1 ohm.
