I have been installed for 1 month 1 DAKIN heat pump with 2 spits. The problem comes from a Spit that makes a sound of "water flow (no apparent leakage) after air diffusion and occasional squealing" could you tell me if this is normal and if not what can it come from.

The flow noise you hear comes from the circulation of heat transfer fluid or condensation in the air conditioner. The squeaking probably comes from a fan bearing. All this is not normal with new equipment. Submit a complaint to your installer.
