1.6 APPLICATION DATA
Safety precautions
• Please read these “Safety Precautions” first then accurately execute the installation work.
• Though the precautionary points indicated herein are divided under two headings, WARNING and CAUTION , those points which are
related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section. However,
there is also a possibility of serious consequences in relationship to the points listed in the CAUTION section as well. In either case, important
safety related information is indicated, so by all means, properly observe all that is mentioned.
• After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please expla in operating methods
as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.
Moreover, ask the customer to keep this sheet together with the owner’s manual.
WARNING
• To disconnect the appliance from the mains supply this appliance must be connected to the mains by means of a circuit breaker or a switch (use
a recognized 20A) with a contact separation of at least 3mm.
• The appliance shall be installed in accordance with national wiring regulations.
• This system should be applied to places as households, residences and the like. Application to inferior environment such as engineering shop
could cause equipment malfunction.
• Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires.
• Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage,
electric shocks and fires.
• For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a
falling of the unit.
• For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment,
and local regulations as well as the installation instructions, and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires.
• Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection
part, through properly securing it improper connection or securing can result in heat generation or fire.
• Take care that wiring does not rise upward, and accurately install the lid/service panel. It’s improper installation can also result heat generation
or fire.
• When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R22) within
the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
• Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water
leakage, electric shock, fire and refrigerant leakage.
• Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with fire, refrigerant could generate toxic gas.
• Confirm after the foundation construction work that refrigerant does not leak.
If coming in contact with fire of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the room could generate toxic gas.
CAUTION
• Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire.
Improper placement of ground wires can result in electric shock.
• The installation of an earth leakage breaker is necessary depending on the established location of the unit.
No installing an earth leakage breaker may result in electric shock.
• Do not install the unit where there is a concern about leakage of combustible gas.
The rare even of leaked gas collecting around the unit could result in an outbreak of fire.
• For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation.
Inadequate plumbing can result in water leakage and water damage to interior items.
• Install the outdoor unit so that the aluminum fins on the air heat exchanger cannot be touched. Failure to observe this may result in injury.
• Do not place objects near the outdoor unit or allow leaves to gather around the unit. If there are objects or leaves around the outdoor unit, small
animals may enter unit and contact electrical parts resulting in break down, emission of smoke or flame.
Cautions for installation
① The system should be applied to places as households, residences and the like.
② The equipment shall be installed in accordance with national wiring regulations.
③ The connection to the fixed wiring of the mains supply must be made via a double pole isolating switch with a contact gap of at least
3mm in each pole.
④ When the outdoor unit has a possibility of being overturned or being displaced and fall from its original installation position , the
outdoor unit should be fixed in its position by use of anchor bolts or wires.

Earthing work
① Cover the connection portion of the refrigerant piping with the
pipe cover and seal them.
If neglecting to do so, moisture occurs on the piping and water
will drip out.
② Finishing and fixing
ⓐ Tie up the piping with wrapping tape, and shape it so that it con-
forms to which the pipe is attached.
ⓑ Fix them with clamps as right figure.

• Earth work shall be carried out without fail in order to prevent electric shock and noise generation.
• The connection of the earth cable to the following substances causes dangerous failures, therefore it shall never be done.
City water pipe, Town gas pipe, TV antenna, lightning conductor, telephone line, etc.
Trial run and operation
① Conduct trial run after confirming that there is no gas leaks.
② When conducting trial run set the remote control thermostat to continuous operation position. However when the power source is cut
off or when the unit’s operation switch is turned off or was turned to fan operation position, the unit will not go into opera tion in
order to protect the compressor.
③ Explain to the customer on the correct usage of the air-conditioner in simple layman’s terms.
④ Make sure that drain flows properly.

(2) Unit ON/OFF button
When the remote control batteries become weak, or if the remote control is lost or malfunctioning, this button may be used to
turn the unit on and off.
(a) Operation
Push the button once to place the unit in the automatic mode. Push it once more to turn the unit off.
(b) Details of operation
The unit will go into the automatic mode in which it automatically determines, from room temperature (as detected by
sensor), whether to go into the cooling or thermal dry modes.
(3) Auto restart function
(a)
Auto restart function records the operational status of the air-conditioner immediately prior to be switched off by a power
cut, and then automatically resumes operations after the power has been restored.
(b)
The following settings will be cancelled:
(i) Timer settings
(ii) HIGH POWER operations
Notes (1) Auto restart function is set at on when the air-conditioner is shipped from the factory.
Consult with your dealer if this function needs to be switched off.
(2) When power failure ocurrs, the timer setting is cancelled. Once power is resumed, reset
the timer.
(3)
If the jumper wire (J7) “AUTO RESTART” is cut, auto restart is disabled. (See the diagram
at right)
(4) Custom cord switching procedure
If two wireless remote control are installed in one room, in order to prevent wrong
operation due to mixed signals, please modify the printed circuit board in the indoor
unit’s control box and the remote control using the following procedure. Be sure to
modify both boards. If only one board is modied, receiving (and operation) can-
not be done.
(a) Modifying the indoor unit’s printed circuit board
Take out the printed circuit board from the control box and cut off jumper
wire (J6) using wire cutters.
After cutting of the jumper wire, take measures to prevent contact with the other
the lead wires, etc.
(b) Modifying the wireless remote control
(i) Remove the battery.
(ii) Cut the jumper wire shown in the gure at right.
