WIRED REMOTE CONTROL UNIT AND EXTERNAL CONNECT KIT (OPTIONAL)
BEFORE INSTALL WIRED REMOTE CONTROL UNIT
• The wired remote control unit and the external connect kit are options. They aren't included in main body of air-
conditioner.
• When you use wired remote control unit, some functions may not be used.
•
please use the recommended wired remote control unit.
(Before installing, Please read the FEATURES AND FUNCTIONS section of OPERATING MANUAL to confirm the
concerned contents.)
CAUTION
(1) Before installing, be sure to disconnect all power supply.
(2) Don't touch the heat exchanger.
(3) During installing or removing operation, be sure not to have wire catched by parts or draw it hard. Or it
may result troubles to the air-conditioner.
(4) Avoid place in direct sunlight.
(5) Select place that will not be affected by the heat from a stove, etc.
(6) Insure the length of wire is not over the recommended maxuim length.
(7) Before setting up the wired remote control unit, please confirm whether air-conditioner can receive the

PUMP DOWN OPERATION (FORCED COOLING OPERATION)
Screws (3 position)
To avoid discharging refrigerant into the atmosphere at the time of relocation or disposal, recover refrigerant by doing the cooling operation or
forced cooling operation according to the following procedure. (When the cooling operation cannot start in winter, and so on, start the forced
cooling operation.)
(1) Do the air purging of the charge hose by connecting the charging hose of gauge manifold to the charging port of 3 way valve and opening the
low-pressure valve slightly.

During the pump-down operation, make sure that the compressor is turned off before you remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2 way or 3 way valve open. This may cause abnormal
pressure in the refrigeration cycle that leads to breakage and even injury.

REMOTE CONTROL UNIT INSTALLATION
CAUTION
(1) Check that the indoor unit correctly receives the
signal from the remote control unit, then install
the remote control unit holder.
(2) Select the remote control unit holder selection
site by paying careful attention to the following:
Avoid places in direct sunlight.
Select a place that will not be affected by the heat
from a stove, etc.
1. REMOTE CONTROL UNIT HOLDER INSTALLATION
• Install the remote control unit with a distance of 23 ft(7
m) between the remote control unit and the photocell
as the criteria. However, when installing the remote con-
trol unit, check that it operates positively.
• Install the remote control unit holder to a wall, pillar,
etc. with the tapping screw (Fig.20).
IMPORTANT
This product has been designed and manufactured to meet ENERGY STAR criteria for energy efficiency when matched
with appropriate coil components. However, proper refrigerant charge and proper air flow are critical to achieve rated
capacity and efficiency. Installation of this product should follow the manufacturer's refrigerant charging and air flow
instructions. Failure to confirm proper charge and air flow may reduce energy efficiency and shorten equipment life.
The method of adjusting inter-unit wire harness
To connect inter-unit wire harness to the terminal correctly, please
refer to Fig. 19 to adjust the length of the part of Inter-unit Wire
harness ahead from conduit holder.

CAUTION
(1) The power source capacity must be the sum of
the air conditioner current and the current of other
electrical appliances. When the current contracted
capacity is insufficient, change the contracted ca-
pacity.
(2) When the voltage is low and the air conditioner is
difficult to start, contact the power company the
voltage raised.
CUSTOMER GUIDANCE
Explain the following to the customer in accordance with the operat-
ing manual:
(1) Starting and stopping method, operation switching, temperature
adjustment, timer, air flow switching, and other remote control unit
operations.
(2) Air filter removal and cleaning, and how to use the air louvers.
(3) Give the operating and installation manuals to the customer.
