1. Notes
1.1 Selecting an installation site for IDU
• Enough space for installation and maintenance.
• The ceiling is level, and the structure is strong enough to support the weight of IDU; take reinforcement
measures when necessary.
• Airflow in/out of the machine is not obstructed, and the external air exerts minimum impact.
• Easy to supply airflow to every corner in the room.
• Easy to drain fluids from the connected piping and water discharge piping.
• No direct heat radiation.
• Avoid installation in narrow spaces or where there are more stringent noise requirements.
CAUTION:
Installing the unit in the following places may cause it to malfunction (please enquire if it is unavoidable):
• Places that contain mineral oil such as machine oil for cutting.
• Places with high salt content in the air such as the sea.
• Areas like hot springs where there are corrosive gases like sulphur gases.
• Factories with major voltage fluctuations in the power supplies.
• Places like a car or cabin room.
• Areas filled with cooking oil and gas like kitchens.
• Places where strong electromagnetic waves are present.
• Places where flammable gases or materials are present.
• Areas where there is evaporation of acid or alkaline gases.
• Other special environmental conditions.
1.2 Selecting an installation site for ODU
• Enough space for installation and maintenance.
• Unobstructed airflow in/out of the unit; no strong breeze.
• The site should be dry and well-ventilated.
• The supporting surface should be flat and able to bear the weight of the unit. The ODU should be able to be
installed horizontally without increasing vibration and noise. Take reinforcement measures when necessary.
• The operating noise and the discharged air should not affect neighbours.
• There should be no leakage of flammable gas nearby.
• It should be easy to install the connecting pipes and complete electrical connections.
• The level difference of connection pipes and the lengths of connection pipes must be within the allowed
ranges.
CAUTION:
• Choose the correct move-in path.
• Carry the device in its original package.
• Electrical insulation measures can be taken in accordance with relevant technical specifications of electrical
equipment if the air conditioner is to be installed onto the metal part of a building.
• If the height difference is greater than the allowed level difference, it is recommended to place the ODU above
the IDU.
