(6) Cautions for wireless remote conntroller operation
As wireless remote controller is operated by infrared rays as a signal, make sure to explain to customers the following matters
regarding the operating distance and protection from jamming.
¡ Operate it by directing the remote controller switch correctly to the receiver amp section.
¡ Operating distance is shown below, but it may become shorter or longer depending on circumstances.
¡ When its receiving section is directly under the sun or strong illumination, or covered by dust or behind an obstacle, the
operating distance may become shorter or it may not work.
¡ A hook for fixing the remote controller is provided for to keep the controller

Scope possible for receiving under illumination at
receiving section of 600 lux.
By switching the dip switch (SW3-3) on the indoor unit printed circuit board ("Specify the following switch number."), the operation
mode can be changed to the quiet mode (mild mode). Confirm at installation and change if necessary.
6.5.2 Installation of the wired remote controller (Optional parts)
(1) Selection of installation location
Following locations should be avoided:
(a) Where exposed to direct sunlight
(b) Near the heat source
(c) Highly humid area or where splashed with water
(d) Uneven installation surface
(2) Selection of installation location
Exposed installation
(a) Remove the remote controller case.
● Insert finger nails between the upper (white) and lower
(brown) cases and ply them to open.
Upper case (white)
(b) Remote controller cords can be taken out upward only as
shown below.
Top
(Cord take-out direction)
● Cut the remote controller lower case off at the top and thin
section with a nipper, knife or other and remove burrs from
the cut with a file or other.
(c) Secure the remote controller lower case on the wall with 2
pieces of wood-screws.

(5) Electrical wiring
™ This air conditioning system should be notificated to supply authority before connection to power supply system.
(a) Selection of size of power supply and interconnecting wires.
OIMPORTANT
● Electric wiring work should be conducted only by authorized personnel.
● Use copper conductor only.
● Power source wires and Interconnecting wires shall not be lighter than polychloroprene
sheathed flexible cord (design HO5RN-F IEC 57).
● Do not connect more than three wires to the terminal block.
● Use round type crimped terminal lugs with insulated grip on the end of the wires.
¡ Select wire sizes and circuit protection from Table 2.

Wiring diagram
™ Wiring diagram is fixed at the backside
of service panel.
THIS UNIT WILL BE STARTED INSTANTLY WITHOUT "ON" OPERATION WHEN ELECTRIC
POWER IS SUPPLIED.
BE SURE TO EXECUTE "OFF" OPERATION BEFORE ELECTRIC POWER IS
DISCONNECTED FOR SERVICING.
● This unit has a function of automatic restart system after recovering power stoppage.
DO NOT LEAVE OUTDOOR UNIT WITH THE SERVICE PANEL OPENED.
● When the service panel is removed, high voltage portion and high temperature areas are
exposed.
OIMPORTANT
● Check that the service valves are fully opened without fail before operation.
● Turn on the power for over 12 hours to energize the crankcase heater in advance of
operation.
● Wait more than 3 minutes to restart the unit after stop.
¡ Run the unit continuously for about 30 minutes, and check the following.
™ Suction pressure at check joint on the compressor suction pipe.
™ Discharge pressure at check joint on the compressor discharge pipe (for Heat pump model), or at check joint of service
valve for gas pipe (for cooling only model).
™ Temperature difference between return air and supply air for Indoor unit.
¡ Refer to “Check Indicator Table” on wiring diagram of Outdoor unit or “User’s manual” of Indoor unit for diagnosis of operation
