Venting
1. Shut off electric supplies to the heater.
2. Turn the flow on (turn the hot water tap on) in order to vent the water installation
(for about 15-30 seconds), until the flow of water becomes constant and even.
3. Turn the flow off (turn the hot water tap off).
4. Switch on the electric supplies.
The venting process must be repeated each time after the water has been
emptied from the unit or pipes.
Operating
The unit is equipped with a differential pressure
switch. It switches heating when there is a proper
water flow through the unit.
There are two indicators on the case:
- green - power supply “on”,
- red - heating “on”.
A user may set the heater on work at lower tem-
perature range by turning the knob in position
I (economic mode - reduced maximum power).
Turning the knob in position II sets the heater
at work at higher temperature range (full power
mode: maximum power = rated power).
Maintenance
1. Cut off power and cold water supplies.
2. Undo the fittings on the inlet pipe.
3. Take the filter out from the fittings at the cold water inlet.
4. Clean the filter and install it in the former position.
5. Connect cold water supply pipe with the inlet connector.
6. Open the cut-off valve on cold water supply pipe - check connections for leaks.
7. Vent the unit and the water system.
