Setting Up the Combi Unit
Flushing and Filling
When installing any Heat pump, we insist on a thorough system flush
prior to connection in line with the Building Regulations for England
and Wales, Part L, 2006. Using the power flusher fill the system with
water and 25% Propylene Glycol, there is no pressure sensor in the
unit so we can operate from 0 -3 bar maximum.
