Fault finding, initial observations
1. The adequate supply and pressure of the water (min. 100kPa).
2. Make sure the cold water inlet and the hot water outlet are not
connected in reverse.
3. The main switch or circuit breaker is switched on.
4. The fuse/circuit breaker is not blown/triggered.
5. Flow rate from cold supply is adequate for the installed Hotrun.
Hint. Try to disconnect the hot water flexi and run it into a bucket
and see if there is warm water coming through. If so the problems
are being caused by new tap ware or blockages in aerators or
restrictors.
