1. Cut off electric supply.
2. Turn the hot water tap on for the period of venting the installation (about 15-30 seconds).
3. Switch power supply on.
The recommended maintenance
needs to be done each time after
a decay of water.
If you do not vent the water
installation, the heater can be
damaged.
Fig.7 Regulation
[7] - back plate
[17] - water inlet coupling
[19] - flow regulating valve
By regulation we understand setting optimal temperature of water, by
limiting the rate of flow.
To reach this purpose do the following:
- shut off electric supplies;
- undo the fixing screw [15]; take the case out of bottom catches [16],
- take the case off;
- set with a tap valve maximum flow of hot water;
- using the flow regulating valve [19] set optimum flow (for instance a
flow that switches on max. power of the heater)
- shut flow with the tap;
- Place the case into two bottom catches [16], screw up the case with
fixing screw [15],
- switch power supplies on.
