| Once the repair work has been completed, check for refrigerant leaks, and check the insulation | ||
| resistance and water drainage. | ||
| Then perform a trial run to check that the air conditioner is running properly. | ||
|
| ||
| After repair work has finished, check there is no trouble. If check is not executed, a fire, electric | ||
Check after | shock or injury may be caused. For a check, turn off the power breaker. | ||
|
| ||
After repair work (installation of front panel and cabinet) has finished, execute a test run to check | |||
repair | |||
there is no generation of smoke or abnormal sound. | |||
| |||
| If check is not executed, a fire or an electric shock is caused. Before test run, install the front | ||
| panel and cabinet. | ||
|
| ||
| Check the following matters before a test run after repairing piping. | ||
| • | Connect the pipes surely and there is no leak of refrigerant. | |
| • | The valve is opened. | |
Do not |
| Running the compressor under condition that the valve closes causes an abnormal high | |
operate the |
| pressure resulted in damage of the parts of the compressor and etc. and moreover if there is | |
unit with the |
| leak of refrigerant at connecting section of pipes, the air is suctioned and causes further | |
valve closed. |
| abnormal high pressure resulted in burst or injury. | |
| Only a qualified installer (∗1) or qualified service person (∗1) is allowed to relocate the air | ||
| conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual | ||
| since a fire, electric shocks, injury, water leakage, noise and/or vibration may result. | ||
|
| ||
| Check the following items after reinstallation. | ||
| 1) The earth wire is correctly connected. | ||
| 2) The power cord is not caught in the product. | ||
| 3) There is no inclination or unsteadiness and the installation is stable. | ||
Check after | If check is not executed, a fire, an electric shock or an injury is caused. | ||
reinstallation |
|
| |
When carrying out the | |||
| |||
| refrigerant pipe. | ||
| Disconnecting the refrigerant pipe with the service valve left open and the compressor still | ||
| operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to | ||
| an abnormally high level, and possibly resulting in reputing, injury, etc. | ||
|
| ||
| When the service panel of the outdoor unit is to be opened in order for the compressor or the | ||
| area around this part to be repaired immediately after the air conditioner has been shut down, set | ||
| the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the | ||
| service panel. | ||
| If you fail to heed this warning, you will run the risk of burning yourself because the compressor | ||
| pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair | ||
| work, wear the kind of insulated | ||
|
| ||
| When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor, | ||
Cooling check | inverter or the areas around these parts to be repaired immediately after the air conditioner has | ||
| been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes | ||
| before opening the service panel. | ||
| If you fail to heed this warning, you will run the risk of burning yourself because the fan motor, | ||
| reactor, inverter heat sink and other parts will be very hot to the touch. | ||
| In addition, before proceeding with the repair work, wear the kind of insulated | ||
| gloves designed to protect electricians. | ||
|
| ||
| Only a qualified installer (∗1) or qualified service person (∗1) is allowed to install the air | ||
| conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks, | ||
| injury, water leakage, noise and/or vibration may result. | ||
|
| ||
| Before starting to install the air conditioner, read carefully through the Installation Manual, and | ||
| follow its instructions to install the air conditioner. | ||
|
| ||
| Do not install the air conditioner in a location that may be subject to a risk of expire to a | ||
| combustible gas. | ||
| If a combustible gas leaks and becomes concentrated around the unit, a fire may occur. | ||
|
| ||
Installation | Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure | ||
themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit | |||
| while the air conditioner is running. | ||
|
| ||
| Install a circuit breaker that meets the specifications in the installation manual and the stipulations | ||
| in the local regulations and laws. | ||
|
| ||
| Install the circuit breaker where it can be easily accessed by the qualified service person (∗1). | ||
|
| ||
| Do not place any combustion appliance in a place where it is directly exposed to the wind of air | ||
| conditioner, otherwise it may cause imperfect combustion. | ||
