Commissioning
If the selected outflow temperature is not reached when the tap is fully
opened, then the water flow through the device exceeds the capacity
of the device (Thermoflow
TM
Elex 8.5/12/15/18/21/24). In this case, the
flow should be reduced with the hot water valve. There is a danger of
scalding at outflow temperatures exceeding 108°F.
Operation
The integrated flow control valve accommodates changes in water
pressure and thus maintains a fairly constant temperature.
This unit is intended for use with shower heads with a low pressure loss.
Mixer taps and thermostatic mixer taps should be of a design compati-
ble with devices with flow control.
Fittings for vented systems should not be used!
Suggestion: To ensure that the minimum flow (switch-on flow) of a water-
pressure operated device is reached, the pressure loss (head loss) of the
device, fittings, shower head, shower hose and piping should all be
considered when installing the device.
Typical pressure losses at a water flow of approx. 2.6 GPM:
• Mixer tap: 5.8 - 11.6 PSI
• Thermostatic mixer tap: 4.4 - 7.3 PSI
• Shower head: 4.4 - 21.8 PSI
The electronically regulated continuous-flow water heater with automat-
ic temperature adjustment keeps the outflow temperature constant.
This takes place regardless of the feed temperature, up to the
temperature limit.
The device has push-buttons to switch it on and off, and arrow keys to
adjust the heat ing. Blue: decrease heating performance, red: increase
heating performance.
Adjust the temperature settings as desired.
