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 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.

Accessories
Accessories supplied with the outdoor unit:
Precautions for Selecting the Location
1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.
2) Choose a location where the hot air discharged from the unit or the operation noise will not cause a nuisance to the neighbors of
the user.
3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
4) There must be sufficient spaces for carrying the unit into and out of the site.
5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
6) The site must be free from the possibility of flammable gas leakage in a nearby place.
7) Install units, power cords and inter-unit cables at least 3 meter away from television and radio sets. This is to prevent interference
to images and sounds. (Noises may be heard even if they are more than 3 meter away depending on radio wave conditions.)
8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air conditioner.
9) Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away from moisture.
NOTE
Cannot be installed hanging from ceiling or stacked.
CAUTION
When operating the air conditioner in a low outdoor ambient
temperature, be sure to follow the instructions described below.
1) To prevent exposure to wind, install the outdoor unit with its suction
side facing the wall.
2) Never install the outdoor unit at a site where the suction side may
be exposed directly to wind.
3) To prevent exposure to wind, it is recommended to install a baffle
plate on the air discharge side of the outdoor unit.
4) In heavy snowfall areas, select an installation site where the snow will not affect the unit.
Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.
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 70 dB(A).

In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts. (Prepare four sets of M8 or M10
foundation bolts, nuts and washers each which are available on the market.)
It is best to screw in the foundation bolts until their length are 20mm from the foundation surface.
Outdoor Unit Installation
1. Installing outdoor unit.
1) When installing the outdoor unit, refer to “Precautions for Selecting the Location” and the “Outdoor Unit Installation
Drawings.”
2) If drain work is necessary, follow the procedures below.
2. Drain work. (Heat pump-models.)
1) Use drain plug for drainage.
2) If the drain port is covered by a mounting base or floor surface, place
additional foot bases of at least 30mm in height under the outdoor unit’s feet.
3) In cold areas, do not use a drain hose with the outdoor unit.
(Otherwise, drain water may freeze, impairing heating performance.)

3. 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.
4. 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 i refrigeration oil for R410A.)nner surface of the flare. (Use
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.

5. Purging air and checking gas leakage.
When piping work is completed, it is necessary to purge the air and check for gas leakage.
WARNING
1) Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.
2) When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.
3) R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.
4) Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum
pump or the unit.
If using additional refrigerant, perform air purging from the refrigerant pipes and
indoor unit using a vacuum pump, then charge additional refrigerant.
Use a hexagonal wrench (4mm) to operate the stop valve rod.
All refrigerant pipe joints should be tightened with a torque wrench at the specified
tightening torque.
*1. Pipe length vs. vacuum pump run time.
*2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists. Check
all pipe joints and retighten nuts as needed, then repeat steps 2) through 4).
1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve’s service port.
2) Fully open gauge manifold’s low-pressure valve (Lo) and completely close its high-pressure valve (Hi).
(High-pressure valve subsequently requires no operation.)
3) Do vacuum pumping and make sure that the compound pressure gauge reads –0.1MPa (–76cmHg)*1.
4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump.
(Keep this state for a few minutes to make sure that the compound pressure gauge pointer does not swing back.)*2.
5) Remove caps from liquid stop valve and gas stop valve.
6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage.
Using soapy water, check for gas leakage from indoor unit’s flare and outdoor unit’s flare and valve rods.
After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and ch at the specified torques.gas stop valves with a torque wren
Pipe length Up to 15 metres
Run time Not less than 10 min.
