Flow regulation
1. Open the hot water tap to the maximum water
ow rate.

Proper ow settings optimise unit performance. Tem-
perature of water depends on the ow rate - higher
ow rate lower water temperature.
Faults

The guarantee does not cover the above repairs.
If there is a fault in the appliance (the heater does not work and all the above reasons
do not occur), contact the seller.
