Safety Precautions

• The precautions described herein are classified as WARNING and CAUTION. They both contain important
information regarding safety. Be sure to observe all precautions without fail.

• Meaning of WARNING and CAUTION notices

WARNING..............Failure to follow these instructions properly may result in personal injury or loss of life.

CAUTION...............Failure to observe these instructions properly may result in property damage or personal injury,

which may be serious depending on the circumstances.

• The safety marks shown in this manual have the following meanings:

Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt.

• After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate
the air conditioner and take care of it with the aid of the operation manual.

WARNING

• Ask your dealer or qualified personnel to carry out installation work.

Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire.

• Install the air conditioner in accordance with the instructions in this installation manual.

Improper installation may result in water leakage, electric shocks or fire.

• Be sure to use only the specified accessories and parts for installation work.

Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.

• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.

A foundation of insufficient strength may result in the equipment falling and causing injury.

• Electrical work must be performed in accordance with relevant local and national regulations and with instructions
in this installation manual. Be sure to use a dedicated power supply circuit only.

Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire.

• Use a cable of suitable length.

Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire.

• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal
connections or wires.

Improper connections or securing of wires may result in abnormal heat build-up or fire.

• When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires
so that the control box lid can be securely fastened.

Improper positioning of the control box lid may result in electric shocks, fire or over heating terminals.

• If refrigerant gas leaks during installation, ventilate the area immediately.

Toxic gas may be produced if the refrigerant comes into contact with fire.

• After completing installation, check for refrigerant gas leakage.

Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.

• When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air,
and use only the specified refrigerant (R410A).

The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.

• During installation, attach the refrigerant piping securely before running the compressor.

If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal
pressure in the refrigeration cycle, which may result in equipment damage and even 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 refrigeration cycle, which may result in equipment damage and even injury.

• Be sure to earth the air conditioner.

Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.

• 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 at any place where there is a danger of flammable gas leakage.

In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.

• While following the instructions in this installation manual, install drain piping to ensure proper drainage and
insulate piping to prevent condensation.

Improper drain piping may result in indoor water leakage and property damage.

• Tighten the flare nut according to the specified method such as with a torque wrench.

If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.

• 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.

• The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are not
thermally insulated.

• Sound pressure level is less than 70dB(A).

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.
Locate the unit so that the noise and the discharged hot air will not annoy the neighbors.

7) Install units, power cords and inter-unit wires at least 3m 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 3m 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 condi-

[Apply oil]

1. Installing outdoor unit

1) When installing the outdoor unit, refer to “Precautions for Selecting the Location” and the “Indoor/Outdoor Unit Installation
Drawings”.

2) If drain work is necessary, follow the procedures below.

2. Drain work

1) Use the 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. Refrigerant piping

• Use the flare nut fixed to the main unit. (To prevent cracking of the flare nut by aged deterioration.)

• To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.)

• 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.

nEnglish 6

4. Purging air and checking gas leakage

WARNING

• Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.

• When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.

• R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.

• Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum
pump or the unit.

• When piping work is completed, it is necessary to purge the air and check for gas leakage.

• 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) Apply vacuum pumping. Check that the compound pressure gauge reads –0.1MPa (–76cmHg).

Evacuation for at least 1 hour is recommended.

4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump.

(Leave as is for 4-5 minutes and make sure the coupling meter needle does not go back.
If it does go back, this may indicate the presence of moisture or leaking from connecting parts. After inspecting all the
connection and loosening then retightening the nuts, repeat steps 2-4.)

5) Remove covers 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.

5. Refilling the refrigerant

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

Precautions when adding R410A
Fill from the gas 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.)

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

6. Charging with refrigerant

1)

If the total length of piping for all rooms exceeds the figure listed below, additionally charge with
for each additional meter of piping.

Outdoor capacity class 3MXS40, 3MXS52, 3AMX52
Total length of piping for all rooms 30m

20g

of refrigerant (R410A)

Even though the stop valve is fully closed, the refrigerant may slowly leak out; do not leave the flare nut removed for a long
period of time.

Cautions on pipe 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.

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 0.045kcal/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.

Gas pipe

Liquid pipe O.D.: 6.4mm / Thickness: 0.8mm (C1220T-O)

Gas pipe insulation I.D.: 12-15mm, I.D.: 16-20mm / Thickness: 13mm min.
Liquid pipe insulation I.D.: 8-10mm / Thickness: 10mm min.

Minimum bend radius

3) Use separate thermal insulation pipes for gas and liquid refrigerant pipes.

O.D.: 9.5mm, 12.7mm / Thickness: 0.8mm (C1220T-O)
O.D.: 15.9mm / Thickness: 1.0mm (C1220T-O)

O.D.: 6.4mm, 9.5mm / 30mm or more
O.D.: 12.7mm / 40mm or more
O.D.: 15.9mm / 50mm or more

8. 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.

• Do not use mineral oil on flared part.

• Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.

• Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.

• Never install a dryer to this R410A unit in order to guarantee its lifetime.

• The drying material may dissolve and damage the system.

• Incomplete flaring may cause refrigerant gas leakage.

Wiring correct example

∗ The figure at left shows branch wiring.

• Before starting the test run, measure the voltage at the primary side of the safety breaker. Check that it is 220-240V.

• Check that all liquid and gas stop valves are fully open.

• Check that piping and wiring all match. The wiring error check can be conveniently used for underground wiring and other wiring
that cannot be directly checked.

1. Wiring error check

• This product is capable of automatic correction of wiring error.

• Press the “wiring error check switch” on the outdoor unit service monitor
print board. However, the wiring error check switch will not function for
one minute after the safety breaker is turned on, or depending on the
outside air conditions (See NOTE 2.). Approximately 10–15 minutes
after the switch is pressed, the errors in the connection wiring will be
corrected.

If self-correction is not possible, check the indoor unit wiring and piping
in the usual manner.

NOTE:

15 nEnglish

1) For two rooms, LED 3 and 4 are not displayed, and for three rooms, LED 4 is not displayed.

2) If the outside air temperature is 5°C or less , the wiring error check function will not operate.
