[6] Notification to design/select HEX (Refrigerant - Water) Warranty for SPILIT solution • Specifications of AHU and compatibility with regulations must be confirmed by your company. • Selection of an apporopriate AHU (with appropriate specifications to match those of units connected to the AHU such as configuration, dimension, life-span, vibration, noise level, or features) must be made by your company.
• The water velocity in pipes should be kept within certain limits of material to avoid erosion,corrosion and excessive noise generation. Be aware, and take care of , that local velocities in small pipes, bends and similar obstructions can exceed the values of previous page. e.g.) Copper : 1.5m/s Warning • Use clean enough water which meets water quality standards. The deterioration of water quality may result in the system breakdown or the water leakage. • Never use anything other than water as a medium.

12. Troubleshooting A flowing water sound or occasional hissing sound is heard. ■ Thease sounds can be heard when refrigerant is flowing in the indoor unit, refrigerant pipe or when the refrigerant is chaging. Water does not heat or cool well. ■ Clean the filter of water piping. (Flow is reduced when the filter is dirty or clogged.) ■ Check the temperature adjustment and adjust the set temperature. ■ Make sure that there is plenty of space around the outdoor unit.
