Reattach the service PCB cover and switch box cover and turn
the power back ON.

NOTICE

Take  care  that  while  running  forced  cooling  operation,  the
water  temperature  remains  higher  than  5°C  (see
temperature  read  out  of  the  indoor  unit).  You  can  achieve
this, for example, by activating all fans of the fan coil units.
