Safety Precautions
Read these Safety Precautions carefully to ensure correct installation.
This manual classifies the precautions into WARNING and CAUTION.
Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING
...............Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.
CAUTION...............Failure to follow any of CAUTION may result in grave consequences in some cases.
The following safety symbols are used throughout this manual:
After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use
and cleaning of the unit according to the Operation Manual.
Be sure to observe this instruction. Be sure to establish an earth connection. Never attempt.
WARNING
Installation should be left to the dealer or another professional.
Improper installation may cause water leakage, electrical shock, or fire.
Install the air conditioner according to the instructions given in this manual.
Incomplete installation may cause water leakage, electrical shock, or fire.
Be sure to use the supplied or specified installation parts.
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.
Install the air conditioner on a solid base that can support the weight of the unit.
An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
Electrical work should be carried out in accordance with the installation manual and the national electrical wiring
rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire.
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
For wiring, use a cable length enough to cover the entire distance with no connection.
Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock or fire.)
Use the specified types of wires for electrical connections between the indoor and outdoor units.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.
After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force
on the electrical covers or panels.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire.
If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
After all installation is complete, check to make sure that no refrigerant is leaking out.
(The refrigerant produces a toxic gas if exposed to flames.)
When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the
specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
During pump-down, stop the compressor before removing the refrigerant piping.
If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.
During installation, attach the refrigerant piping securely before running the compressor.
If the compressor is not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing
abnormal pressure in the freezer cycle which will lead to breakage and even injury.
Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.
Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks, or fire.
CAUTION
Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage.
If the gas leaks and builds up around the unit, it may catch fire.
Establish drain piping according to the instructions of this manual.
Inadequate piping may cause flooding.
Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.

Choosing an Installation Site
Before choosing the installation site, obtain user approval.
1. Indoor unit.
The indoor unit should be sited in a place where:
1) the restrictions on installation specified in the indoor unit installation drawings are met,
2) both air intake and exhaust have clear paths met,
3) the unit is not in the path of direct sunlight,
4) the unit is away from the source of heat or steam,
5) there is no source of machine oil vapour (this may shorten indoor unit life),
6) cool (warm) air is circulated throughout the room,
7) the unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as they may shorten the
remote control range,
8) the unit is at least 1 metre away from any television or radio set (unit may cause interference with the picture or sound),
9) install at the recommended height (1.8m).
2. Wireless remote controller.
1) Turn on all the fluorescent lamps in the room, if any, and find the site where remote control signals are properly received
by the indoor unit (within 7 metres).

Installation Tips
1. Removing and installing front panel.
• Removal method
1) Place your fingers in the indentations on the main unit (one each on the
left and right sides), and open the panel until it stops.
2) Continue to open the front panel further while sliding the panel to the right
and pulling it toward you in order to disengage the rotating shaft on the
left side. To disengage the rotating shaft on the right side, slide the panel
to the left while pulling it toward you.
• Installation method
Align the tabs of the front panel with the grooves, and push all the way in. Then
close slowly. Push the center of the lower surface of the panel firmly to engage the
tabs.
2. Removing and installing front grille.
• Removal method
1) Remove front panel to remove the air filter.
2) Remove the screws (2) from the front grille.
3) In front of the !!! mark of the front grille, there are 3 upper hooks.
Lightly pull the front grille toward you with one hand, and push down on
the hooks with the fingers of your other hand.
When there is no work space because the unit is close to ceiling
CAUTION
Be sure to wear protection gloves.
Place both hands under the center of the front grille, and while pushing up, pull it toward you.
• Installation method
1) Install the front grille and firmly engage the upper hooks (3 locations).
2) Install 2screws of the front grille.
3) Install the air filter and then mount the front panel.
3. How to set the different addresses.
When two indoor units are installed in one room, the two wireless remote controllers
can be set for different addresses.
1) In the same way as when connecting to an HA system, remove the metal plate
electrical wiring cover.
2) Cut the address jumper (JA) on the printed circuit board.
3) Cut the address jumper (J4) in the remote controller.
