Installation must be done by the installer or its service agent.
Install the unit correctly according to the installation manual.
When installing the unit in a small place, take measures in order to keep the refrigerant concentration from
exceeding allowable safety limits in the event of a refrigerant leak.
If any gas or impurities except R-410A refrigerant get into the refrigerant pipe, serious problems may occur and
this may cause injury.
Install the unit safely on a place that can support its weight.
