Remarks
Details on foundation work, duct work, insulation work, electrical wiring, power source switch, and other items shall be referred to the Installation
Manual.
Due to continuing improvement, above specifications may be subject to change without notice.
The ambient temperature of the Heat Source Unit needs to be kept below 104°FD.B. (40°CD.B.)
The ambient relative humidity of the Heat Source Unit needs to be kept below 80%.
The Heat Source Unit should not be installed at outdoor.
Be sure to mount a strainer (more than 50 meshes) at the water inlet piping of the unit.
Be sure to provide interlocking for the unit operation and water circuit.
Install the supplied insulation material to the unused drain-socket.
When installing insulation material around both water and refrigerant piping, follow the installation manual.
The cooling tower and the water circuit must be a closed circuit (water is not exposed to the atmosphere).
Add brine to circulating water when a unit is operating at water temperature below 50°F (10°C), and turn DipSW4 (773) ON before power ON.
It is recommended to set the brine concentration to a percentage that will keep the freezing temperature at -15°C or less.
