<Detection method> This alarm goes off when the pressures detected by the circulating fluid pressure
sensor (for discharge) reach the following values.
- Standard pump: The alarm will not be generated.
- Option T (High pressure pump): 0.70 MPa
- Option MT (High pressure pump for pure water): 0.60 MPa

Replace the main board.
See section "4.5.16
Replacement of main board
& communication board".
The heat exchanger, which is
an evaporator and a part of
the refrigerant circuit, needs
to be replaced. Only a
specialized operator is
allowed to handle the
refrigerant circuit.
See document No. HRX-MM-
Q014 for replacement.
