1. 

Secure the twin connectors with flat gaskets to the
connections of the sub-mounting kit.
If available:
Fit a flow indicator (accessories) with flat gasket in
place of the twin connector to the heating water
return of the heating circuit without mixer.

2. 

Connect the heating circuits to the connection
pipes of the sub-mounting kit.
Do not alter the position of the heating circuit con-
nections, so the casing can be fitted later.
