Figure 16: Cooling cover
The cooling coil is installed in the housing cover. For the inlet and outlet of cooling fluid, connection
pieces with cutting ring screw connections according to DIN 2553 are provided on the housing cover
for a connection of a pipe with an external diameter of 10 mm.
Remove the sealing plug from the screw necks prior to assembly and flush the cooling coil to prevent
any contamination of the cooling system. Then, connect the connection pieces with the coolant circuit.
The flow direction of the coolant is irrelevant.
