It is important that all previously mentioned preparations have been
carried out before the heat pump is connected to the heating system. Also
ensure the system has been power fl ushed before it is connected to the
heat pump. Flushing protects the heat pump from contamination.
Oxygen must not enter the system. The heat pump is only intended
to work in oxygen free systems. If oxygen enters the system it causes
corrosion in the heat pump which could block the fi lter on the heating
