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 40°C D.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.
