Direction of Piping
|
| ! WARNING | ||
| ● | Please request your sales agent or qualified technician to install your unit. Water leakage, short circuit or fire may occur if you | ||
|
| do the installation work yourself. | ||
|
|
|
|
|
| ● | Please observe the instructions stated in the installation manual during the process of installation. Improper installation may | ||
|
| cause water leakage, electric shock and fire. | ||
|
|
|
|
|
| ● | Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the | ||
|
| units may collapse and impose danger. | ||
|
|
|
|
|
| ● | Observe the rules and regulations of the electrical installation and the methods described in the installation manual when | ||
|
| dealing with the electrical work. Use power cables approved by the authorities of your country. | ||
|
|
|
|
|
| ● | Be sure to use the specified wire for connecting the indoor and outdoor units. Please ensure that the connections are tight | ||
|
| after the conductors of the wire are inserted into the terminals. Improper insertion and loose contact may cause | ||
|
| and fire. | ||
|
|
|
| |
| ● | Please use the specified components for installation work. Otherwise, the units may collapse or water leakage, electric shock | ||
|
| and fire may occur. | ||
|
|
|
|
|
| ● | Be sure to use the specified piping set for R410A. Otherwise, this may result in broken copper pipes or faults. | ||
|
|
|
| |
| ● | When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigeration cycle. Otherwise, | ||
|
| pressure in the refrigeration cycle may become abnormally high so that a rupture may be caused. | ||
|
|
|
| |
| ● | Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fire, a poisonous | ||
|
| gas may occur. |
