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 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.

6
Max temp error. The maximum temperature
reached is lower than 92°c during the calibration
process.
Check your height above sea level.
Call Zip Service.
7
Over temp error. A constant temperature over
103°C has been reached during the calibration
process.
Make sure there is an airgap in the vent
line.
Call Zip service.
8
Calibration error, water temperature is falling
or constant when maximum element power is
applied.
When water runs from the outlet tap turn
water supply off to unit. Restart calibration.
