2.6. Other system components: fancoils Climma fancoils have to be installed in a technical space inside or close to the cabin they have to cool/heat. Fancoils need to be properly secured on a leveled surface in order to operate correctly and remove the condensation.
Page 7: Other System Components: Fresh Water Circuit
Water pressure in the circuit must be between 1 and 1.5 Bar (14.5 and 22 psig). FRESH WATER PUMP (CIRCULATION PUMP) The fresh water pump must be installed near the Climma DC chiller. The pump has to be installed on the return line of the fresh water circuit, pumping water directly in the chiller and then to the fancoils.
