NOTE
If the outdoor unit makes noises at low outside temperatures, even although it is switched off, this is not a
malfunction. This is the winding of the compressor being run briefly in order to heat up the oil within it and
also to guarantee the viscosity at low ambient temperatures. If you do not use the unit in the winter then
you can switch off the breaker. Switch it back on again at least 12 hours before the next time that the unit
will be required!
