Figure 29 – Components of Dimplex solar pump unit SOLPU1 and SOLPU2

Pump unit connections (1, 2, 10 and 13)

The SOLPU1 pump unit connections can be utilised in three different ways:

-3/4” flat seal at the end of corrugated stainless steel pipe

-3/4”F x 22mm straight connection

-15mm reducing set

The 15mm reducing set is included in the delivery of the SOLPU1 pump unit, the ¾” flat seal is part of the delivery of the Dimplex solar flexible hose SOLFH10/15. The ¾”F x 22mm straight connection has to be provided by the installer.

The SOLPU2 pump unit connections follow the same principle as those of the SOLPU1 except that the connection diameters are increased:

-1” flat seal at the end of corrugated stainless steel pipe

-1”F x 22mm or 1”F x 28mm straight connection

-22mm reducing set

The 22mm reducing set is included in the delivery of the SOLPU2 pump unit, the 1” flat seal should be part of a DN20 corrugated stainless steel hose. Note, the Dimplex solar
