Warnings about Installation of Receivers
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 infl uences, so take care in where the unit is installed.
• Inverter or rapid-start type fl uorescent lights. (Models without glow lamps)
• Plasma display or LCD televisions.
• Direct sunlight or other sources of bright light.
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.
• Locate where no warm or cold drafts will affect it.
• Locate in a place free from direct sunlight.
• Locate where it will not be affected by any other heat/cold source.
Customer Explanation
Give the Operating Instructions and this manual to the customer after fi nishing the installation.
Use the Operating Instructions to explain to the customer how to use and care for the unit.
Things to remember when wired and wireless remotes are
installed at the same time
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.
(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.
When 1 indoor unit is operated by 2 remote controllers:
Either of the remotes can be set to main/sub.

Installing the Receiver
When using a separately installed receiver as a built-in model, install it to the switch box (fi eld
supply) shown in the diagram on the right, which has been built into the wall on site in advance.
1 Remove the face plate of the receiver by slipping a slotted screwdriver or the like into the cutout on the bottom.
2 Install the receiver with the 2 enclosed small screws.
3 Connect the receiver's wiring (2 cores) with the wiring from the indoor unit. (Refer to the chapter on wiring the
receiver)
When wiring receivers, 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.)
4 Attach the face plate.

When using a separately installed receiver as an exposed model, attach it to a wall where the
receiver can be affi xed.
1 Put a slotted screwdriver or the like into the groove on the bottom of the receiver unit and twist it to remove the
bottom of the case. (Fig. A)
2 To enable the receiver's wiring to stick out from the upper part of the case (thin part at center-top), use side-cutters
or the like to cut a hole in the case big enough for the remote control wiring (sold separately). (Fig. B)
3 Disconnect the wires that were connected at shipment from the connector.
4 After installing the remote control wiring (sold separately) at the position in Fig. C with the enclosed cable tie,
connect it to the connector on the receiver.
5 Shape the remote control wiring at the top of the PCB so it fi ts inside the receiver and after confi guring the wiring
like it is in Fig. D, attach the lower case. When doing this, arrange the head of the cable tie so it face sideways.
6 Remove the face plate and use the woodscrews (2) to install the receiver unit.
7 Use the cord clip that comes enclosed with the remote control wiring to fasten it to the wall.
8 Attach the face plate.
