The temperature of the water is determined by the power setting and regulation of water flowing
through the unit (see table on hot water output).
If temperature control knob (1) is set to "off" and water flow knob (2) is opened a cold shower is
available.
CAUTION:
Turning flow control knob (2) slowly anti clockwise uses any residual heat in the appliance and
prevents short periods of increased temperature if water is drawn away again.
Variations in inlet temperature and flow caused by the water mains are not detected by the
appliance. A reduction in the flow and/or an increase in the inlet temperature raises the water
temperature.
If there is a pressure tank (for the water supply) in the building, the rapid changes on the water
pressure, deriving from switching on/off of the pressure tank, can effect the temperature of the
water relieved from the shower head!
Note: A safety valve is triggered if the shower hose is kinked or the shower head is furred.
Water escapes from the rear of the appliance.
Hot water output
DE 04200
Voltage V
Formula: cold water inlet temperature + flow at switch on = hot water outlet temperature
Example: For 220 V / 3.4 kW and 2.5 l/min
15 ºC + 19 K = 34 ºC
DE 04200
Voltage V
Formula: cold water inlet temperature + temperature increase (at l/min) = hot water outlet temperature
Example: For 220 V / 3.4 kW and 1.8 l/min
15 ºC + 26.4 K = 41.4 ºC
