6.4.1 Connection to the pipe network
The flow and return connections protrude laterally from the housing. The heat exchanger connection dimensions are:
1" (series 54+55)
1 ¼" (series 56)
Proceed as follows when connecting up the unit's hydraulic pipework:
Disconnect the supply line from the medium.
Connect up the pipework.
Remove protective caps from the flow and return.
Seal the valve connections and screw in place.
Important! Use an appropriate tool (e.g. pipe wrench) to prevent connection spigots from being sheared off and
twisted. Ensure that the connections are installed tension-free!
