with the control onto the back insulation.
Now the front insulation can be slipped over the control
retainer and be pushed onto the back insulation until it
clicks into position.

liquid and carry out leakage test. Set the pump speed to
suit either the number of collectors or the collector sur-
face area. If required, fine adjustment is carried out with
the ball valve within the flow measuring device.

thermal insulation.

tailed in the separate operating instructions supplied
with each transmission station.
