Please take note of the following important points when installing.
• Do not install the unit where leakage of flammable gas may occur.
If gas leaks and accumulates around the unit, it may cause fire ignition.
• Do not overcharge the unit.
This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.
• This unit is designed for indoor installation only.
• Installation work should be done by authorized dealer or qualified contractor.
• Install the unit at a suitable minimum distance or shortest path to the coupling fan coil unit.
• There should be sufficient space for piping connection, service and maintenance. (Refer to Figure 2)
• The area should be isolated from vibration and noise.
• Ensure the area is free from water leakage.
• This unit will be mounted on the ceiling by the support of four threaded rods. (Refer to Figure 4)
• Ensure that the supports are strong enough and properly anchored to withstand the weight of the unit.
• Use isolator rubber (natural rubber) with hardness of 35° for better noise and vibration control.
• Do not locate the drainage system at any point above the drain connection.
