Heating system supply pipe and return pipe

▪ Install a filter (max mesh size 0.7 mm) in the heating system's return pipe to protect the unit against foreign particles.
▪ Install the supply line with all the accompanying components.
▪ Ensure that the correctly dimensioned system pump is connected to the heating system's supply line, and connect the system
pump's control cables to the correct terminal block (see connection of system pump).
▪ Install the return line with all the accompanying components.
▪ Insulate the supply and return lines.
6.3 Noise information
To prevent disturbing noise from the heat pump the following recommendations should be observed:
▪ The heat pump's pipe connections cause vibration. In order to prevent this vibration spreading to the heating system and frame,
the pipes should be connected and laid with particular care.
▪ The brine and heat transfer fluid should normally be connected to the heat pump by means of a flexible hose.
▪ Pipes must not be attached to roofs or walls facing noise-sensitive areas.
▪ In cases where attachment of pipes to sensitive construction elements cannot be avoided, special elastic pipe attachments should
be used.
▪ Not correctly adjusted feet, can cause unwanted noise.
