Possible extended recirculation of water through the
bypass > 50°C bypass. Check:
• that the humidification capacity set on screen Dc18 is
equal to the no. of nozzles x capacity of each nozzle;
• that the zone can deliver a flow-rate of water ≥ the
minimum flow-rate supplied by the pump;
• that the NTC probe is connected to terminals J5.2-J5.3
• Check pump wear and oil every 1000 operating hours
Pressure measured by Possible small water leaks at the outlet, check tightness
probe RHP < 60 bars of the hose fittings and make sure there are no leaks from
with pump running the drain solenoid valves DR1 and DR2.
Check that the pump is able to deliver the flow-rate
required to satisfy the load provided by the nozzles.
