Hose connections should ideally be carried out using the optional accessory, hose sealing
cap DN 100 with hose connector 3x13 mm, 1x19 mm (art. no. 107613). The hose sealing
cap is also included in the convenient connection kit.
If PU foam is used for sealing, the hose surfaces and pipe walls are to be cleaned with water,
and should be dampened slightly with water before foaming; when foaming, make sure that each hose is
covered on all sides with PU foam. To ensure good insertion of foam and proper coating of the hoses,
these should be moved slightly in a longitudinal direction when inserting the PU foam.
