Operating

The unit switches on automatically right after
reaching appropriate rate of flow. When the
rate of flow rises the second step switches
on. A user may set the heater on work at
lower temperature range by turning the
knob in position I (economic mode - reduced
maximum power). Turning the knob in posi-
tion II sets the heater at work at higher tem-
perature range (full power mode: maximum
power = rated power).
There are two indicators on the case:
green - power supply "on",
red
- heating "on".
