WAHLBACH 18kW, 21kW, 24kW Instructions De Montage Et D'utilisation page 20

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 compatible
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 shower water flow of approx. 10L/min.
• Mixer tap: 0.4 - 0.8bar
• Thermostatic mixer tap: 0.3 - 0.5bar
• Shower head: 0.3 - 1.5bar.

The electronically-regulated continuous-flow water heater with automatic performance ad-
justment keeps the outflow temperature constant. This takes place irrespective of the feed
temperature, up to the performance limit. The hot water outflow temperature is infinitely
variable.
User instructions:
• The appliance shall have a control panel
• with a display that is able to continuously monitor the level you have set
• there are also push-buttons to switch the appliance on and off, and the
arrows can be used to increase or decrease the temperature levels:

Without a temperature limiter, high temperatures may be reached at
draw-off points. Keep children away from the draw-off points. Danger
of scalding!
The device should be isolated from the electricity supply before any
work is done on live components.
Remove the fuses or isolate the device in another way.

These are typical values. Depending on the circumstances,
there may be slight differences between the declared values
and actual measured values.
It may happen that the declared values are
not achieved because the flow rate is too
high for the nominal power rating of the
device.
On delivery the device is set to level 3.
