Inlet Pressure Regulator
Sporadically, dust or iron particles from the outer tubes during the first installation and
during maintenance operations to external filters can clog the regulator.
To replace the pressure regulator, disconnect inlet and outlet tubes and undo the 2 screws
(a,b) located on the backside of the chiller.
During removal, be careful not to damage the electric wiring or the refrigeration group
pipes.
For reassembly, repeat the same operations in reverse order.
