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.
• The English text is the original instruction. Other languages are translations of the original instructions.
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 the supply cord is damaged, it must be replaced by the manufacturer, a service agent or similarly qualified
persons in order to avoid a hazard.
• 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.

–,
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) to avoid accidental touching, it is recommended to install the unit higher than 2,5m.
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).
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.
• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for
commercial and household use by lay persons.
• Sound pressure level is less than 70dB(A).
• Before obtaining access to terminal devices, all power supply circuits must be interrupted.

5. Drain piping.
1) Connect the drain hose, as described right.
2) Remove the air filters and pour some water into the drain pan to check the water flows
smoothly.
3) If drain hose extension or embedded drain piping is required, use appropriate parts that match the hose front end.
[Figure of Hose Front End]
4) When extending the drain hose, use a commercially available
extension hose with an inner diameter of 16 mm. Be sure to
thermally insulate the indoor section of the extension hose.
5) When connecting a rigid polyvinyl chloride pipe
(nominal diameter 13mm) directly to the drain
hose attached to the indoor unit as with
embedded piping work, use any commercially
available drain socket (nominal diameter 13mm)
as a joint.
Refrigerant Piping Work
1. Flaring the pipe end.
1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing
downward so that the chips do not enter the pipe.
3) Put the flare nut on the pipe.
4) Flare the pipe.
5) Check that the flaring is properly made.
WARNING
1) Do not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.
4) Do never install a drier to this R410A unit in order to guarantee its lifetime.
5) The drying material may dissolve and damage the system.
6) Incomplete flaring may cause refrigerant gas leakage.
The drain hose should
be inclined downward.
No trap is permitted.
Do not put the end
of the hose in water.

Refrigerant Piping Work
2. Refrigerant piping.
CAUTION
1) Use the flare nut fixed to the main unit. (To prevent cracking of the flare nut by aged deterioration.)
2) To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.)
3) Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage.
Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand. Then tighten them fully with the torque wrenches.
2-1. Caution on piping handling.
1) Protect the open end of the pipe against dust and moisture.
2) All pipe bends should be as gentle as possible. Use a pipe bender
for bending.
2-2. Selection of copper and heat insulation materials.
• When using commercial copper pipes and fittings, observe the following:
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045 kcal/(mh•°C))
Refrigerant gas pipe’s surface temperature reaches 110°C max.
Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation
dimensions as below.
3) Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
