Check that the appliance is the right size for this pool and its environment.
- Air is trapped in the circuit: purge the installation.
- The water flow rate is too high; reduce the operating speed: (see § « 3.4.2 Operation of the
circulating pump on Heat Line Plus »).
- There is air in the circulating pump; let it run. It will bleed itself.
- The water flow is too low: increase the pressure in the primary circuit and/or check the air
