– 1 – Precautions for safety Please read this Installation Manual carefully before installing the Air Conditioner. • This Manual describes the installation method of the indoor unit. Installing, starting up, and servicing air--conditioning equipment can be hazardous due to system pressures, •...
Important notices • For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the compressor before disconnecting the refrigerant pipe. If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.
– 3 – Selection of installation place Installation under high-humidity atmosphere In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere Avoid installing in the following places (dew-point temperature: 73 °F (22.8 °C) or higher). Select a location for the indoor unit where the cool or warm air will circulate evenly.
