6.4.2 Connection to the pipe network
The flow and return connections are located as standard at the side of the casing on the left side of the unit, as seen from the
air intake. The heat exchanger connection is 3/4".
Proceed as follows when connecting up the unit's hydraulic pipework:
Shut off the supply line from the heating medium.
Connect up the pipework.
Remove protective caps from the flow and return.
Seal and screw in connections, holding the nut to prevent it from shearing off and twisting.
Important! Use an appropriate tool (e.g. wrench AF 32) to secure the connecting nut and prevent it from shear-
ing and twisting! Ensure that the connections experience no mechanical tension when fitted!
