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:
Be sure to observe this instruction.		Be sure to establish an earth connection.	Never attempt.

•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.

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.

English

• 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).

Accessories

It is on the bottom of the packing case.

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.

Construct a large canopy. Construct a pedestal.

Install the unit high enough off the ground to prevent burying in snow.

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)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 gas stop valves with a torque wrench at the specified torques. *1. Pipe length vs. vacuum pump run time.

Pipe length	Up to 15 metres
Run time	Not less than 10 min.

*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).

6. Refilling the refrigerant.

Check the type of refrigerant to be used on the machine nameplate.

Precautions when adding R410A

Fill from the liquid pipe in liquid form.

It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.

1)Before filling, check whether the cylinder has a siphon attached or not. (It should have something like “liquid filling siphon attached” displayed on it.)

Filling a cylinder with an attached siphon

Stand the cylinder upright when filling.

There is a siphon pipe inside, so the cylinder need not be upside-down to fill with liquid.

Filling other cylinders

Turn the cylinder upside-down when filling.

• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.

Pump Down Operation

In order to protect the environment, be sure to pump down when relocating or disposing of the unit.

1)Remove the valve cap from liquid stop valve and gas stop valve.

2)Carry out forced cooling operation.

3)After five to ten minutes, close the liquid stop valve with a hexagonal wrench.

4)After two to three minutes, close the gas stop valve and stop forced cooling operation.

How to force cooling operation mode

 Using the indoor unit operation/stop button

Press the indoor unit operation/stop button for at least five seconds. (Operation will start.)

•Forced cooling operation will stop automatically after around 15 minutes. To force a test run to stop, press the indoor unit operation/stop button.

Using the main unit’s remote controller

1)Press the “operation/stop” button. (Operation will start.)

2)Press the temperature button and the “operation select” button at the same time.

3)Press the “operation select” button twice.

Wiring

WARNING

1)Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical shock, or fire.

2)Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the terminal block.) Doing so may cause electric shock or fire.

3)Be sure to install an earth leakage breaker. (One that can handle higher harmonics.)

(This unit uses an inverter, which means that it must be used an earth leakage breaker capable handling harmonics in order to prevent malfunctioning of the earth leakage breaker itself.)

4)Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.

5)Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.

•Do not turn ON the power supply until all work is completed.

1)Strip the insulation from the wire (20mm).

2)Connect the connecting wires between the indoor and outdoor units so that the terminal numbers match. Tighten the terminal screws securely. We recommend a flathead screwdriver be used to tighten the screws. The screws are packed with the terminal board.

Firmly fix the wires with

the terminal screws.
