Warnings about Installation of Receivers  
Main/sub remote controllers will work regardless of which indoor unit they are installed to.  
The wireless remote uses a very weak infrared light for its signal, which can result in the signal not  
being received because of the following influences, so take care in where the unit is installed.  
• Inverter or rapid-start type fluorescent lights. (Models without glow lamps)  
• Plasma display or LCD televisions.

Warnings about Installing Remote Controllers  
If a remote controller is to be operated from a remote control holder that is hung on a wall, turn  
on the lights in the room as well as any electrical appliances and then check to make sure the air  
conditioner works with the remote controller in the location where it will be installed. If it works,  
continue with installation.  
If the air conditioner is to be switched from the main sensor to a remote control sensor, pay attention  
to the following when installing.

Two remote controllers can be used to control the unit if the wireless remote controller is installed at the  
same time as the wired remote controller.  
Spacer  
(Up to 2 remotes [a wireless remote controller and the wired remote controller] can be installed.)  
When using 2 remotes, one or more units can be operated by the remotes.  
<Note> When wiring remote controllers, be sure to double-check the terminal numbers of the indoor unit before  
connecting them so there are no mistakes in the wiring. (Damage will occur if high voltage [e.g. supply  
voltage] is applied.)  
<Note> It is not possible to use more than one wireless remote controller with one indoor unit. (A receiver located  
separately can be used at the same time.)  
<Note> If both a wireless and a wired remote controller are to be installed and used at the same time, one of  
them must be set up as the sub remote controller.  
If the wired remote controller is to be the sub remote, change the wired remote controller to the sub remote.  
If the wireless remote controller is to be the secondary, turn the #3 switch on the wireless receiver (operation  
panel) from OFF to ON.

<Note 1> If the wiring to the operation panel is bundled together with other wiring, such as the incoming line from  
the power source, it can cause a malfunction, so avoid doing so.
