2.2.Choosingtheoutdoorunitinstallationlocation
/R32 is heavier than air—as well as other refrigerants—so tends to accumulate at
the base (in the vicinity of the oor). If R32 accumulates around base, it may reach
a ammable concentration in case room is small. To avoid ignition, maintaining a
safe work environment is required by ensuring appropriate ventilation. If a refrig-
erant leak is conrmed in a room or an area where there is insufcient ventilation,
refrain from using of ames until the work environment can be improved by ensur-
ing appropriate ventilation.
•Avoid locations exposed to direct sunlight or other sources of heat.
•Select a location from which noise emitted by the unit will not inconvenience
neighbors.
•Select a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, ow, or accu-
mulate.
•Note that water may drain from the unit during operation.
•Select a level location that can bear the weight and vibration of the unit.
•Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation loca-
tion or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airow
and a malfunction may result.
•Avoid locations exposed to oil, steam, or sulfuric gas.
•Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or ngers may be pinched.
•Refrigerant pipes connection shall be accessible for maintenance purposes.
/Install outdoor units in a place where at least one of the four sides is open, and in
a sufciently large space without depressions. (Fig. 2-2)

2.4.1.Windylocationinstallation
When installing the outdoor unit on a rooftop or other location unprotected from the
wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.
Strong wind entering the air outlet may impede the normal airow and a malfunction
may result.
The following shows three examples of precautions against strong winds.
1Face the air outlet towards the nearest available wall about 50 cm away from the
wall. (Fig. 2-4)
2Install an optional air guide if the unit is installed in a location where strong winds
from a typhoon, etc. may directly enter the air outlet. (Fig. 2-5)

4.Installingtherefrigerantpiping
4.3.Refrigerantpiping(Fig.4-4)
Remove the service panel D(4 screws) and the cover panel front A(2 screws) and
cover panel rear B(4 screws).
1Perform refrigerant piping connections for the indoor/outdoor unit when the out-
door unit’s stop valve is completely closed.
2Vacuum-purge air from the indoor unit and the connection piping.
3After connecting the refrigerant pipes, check the connected pipes and the indoor
unit for gas leaks. (Refer to 4.4. Refrigerant pipe airtight testing method)
4A high-performance vacuum pump is used at the stop valve service port to main-
tain a vacuum for an adequate time (at least one hour after reaching –101 kPa (5
Torr)) in order to vacuum dry the inside of the pipes. Always check the degree of
vacuum at the gauge manifold. If there is any moisture left in the pipe, the degree
of vacuum is sometimes not reached with short-time vacuum application.
After vacuum drying, completely open the stop valves (both liquid and gas) for the
outdoor unit. This completely links the indoor and outdoor refrigerant circuits.
•
If the vacuum drying is inadequate, air and water vapor remain in the refrigerant
circuits and can cause abnormal rise of high pressure, abnormal drop of low
pressure, deterioration of the refrigerating machine oil due to moisture, etc.
• If the stop valves are left closed and the unit is operated, the compressor and
control valves will be damaged.
• Use a leak detector or soapy water to check for gas leaks at the pipe connec-
tion sections of the outdoor unit.
• Do not use the refrigerant from the unit to purge air from the refrigerant lines.
• After the valve work is completed, tighten the valve caps to the correct torque:
20 to 25 N·m (200 to 250 kgf·cm).
Failure to replace and tighten the caps may result in refrigerant leakage. In
addition, do not damage the insides of the valve caps as they act as a seal to
prevent refrigerant leakage.
5Use sealant to seal the ends of the thermal insulation around the pipe connection
sections to prevent water from entering the thermal insulation.

4.4.Refrigerantpipeairtighttestingmethod(Fig.4-5)
(1)
Connect the testing tools.
• Make sure the stop valves ABare closed and do not open them.
• Add pressure to the refrigerant lines through the service port Cof the liquid
stop valve A.
(2)
Do not add pressure to the specied pressure all at once; add pressure little by
little.
1Pressurize to 0.5 MPa (5 kgf/cm2G), wait ve minutes, and make sure the pres-
sure does not decrease.
2Pressurize to 1.5 MPa (15 kgf/cm2G), wait ve minutes, and make sure the
pressure does not decrease.
3Pressurize to 4.15 MPa (41.5 kgf/cm2G) and measure the surrounding tem-
perature and refrigerant pressure.
(3)
If the specied pressure holds for about one day and does not decrease, the pipes
have passed the test and there are no leaks.
• If the surrounding temperature changes by 1 °C, the pressure will change by
about 0.01 MPa (0.1 kgf/cm2G). Make the necessary corrections.
(4)
If the pressure decreases in steps (2) or (3), there is a gas leak. Look for the
source of the gas leak.
4.5.Stopvalveopeningmethod
The stop valve opening method varies according to the outdoor unit model. Use the
appropriate method to open the stop valves.
(1)
Gas side (Fig.4-6)
1Remove the cap, pull the handle toward you and rotate 1/4 turn in a counterclock-
wise direction to open.
2Make sure that the stop valve is open completely, push in the handle and rotate
the cap back to its original position.
(2)
Liquid side (Fig.4-7)
1Remove the cap and turn the valve rod counterclockwise as far as it will go with
the use of a 4 mm hexagonal wrench. Stop turning when it hits the stopper.
(ø9.52: Approximately 10 revolutions)
2Make sure that the stop valve is open completely, push in the handle and rotate
the cap back to its original position.
Refrigerant pipes are protectively wrapped
•The pipes can be protectively wrapped up to a diameter of ø90 before or after
connecting the pipes. Cut out the knockout in the pipe cover following the groove
and wrap the pipes.
Pipe inlet gap
•Use putty or sealant to seal the pipe inlet around the pipes so that no gaps remain.
(If the gaps are not closed, noise may be emitted or water and dust will enter the
unit and breakdown may result.)
4.6.Additionofrefrigerant
•Additional charging is not necessary if the pipe length does not exceed 30 m.
•If the pipe length exceeds 30 m, charge the unit with additional R32 refrigerant
according to the permitted pipe lengths in the chart below.
* When the unit is stopped, charge the unit with the additional refrigerant through
the liquid stop valve after the pipe extensions and indoor unit have been vacu-
umized.
When the unit is operating, add refrigerant to the gas check valve using a
safety charger. Do not add liquid refrigerant directly to the check valve.
* After charging the unit with refrigerant, note the added refrigerant amount on
the service label (attached to the unit).
Refer to the “1.5. Using R32 refrigerant air conditioners” for more information.
•Be careful when installing multiple units. Connecting to an incorrect indoor unit
can lead to abnormally high pressure and have a serious effect on operation
performance.
/ R32 maintenance relling: Before servicing relling the equipment with R32 to
ensure that there is no risk of explosion from electrical sparks it must be ensured
that the equipment machine is 100% disconnected from the mains supply.
IDouble spanner section
(Do not apply a spanner other than to this section.
Doing so would cause coolant leaks.)

(Seal the end of the heat insulation material at the
pipe connection section with whatever seal mate-
rial you have on hand so that water does not inl-
trate the heat insulation material.)

7.1.Beforetestrun
►Aftercompletinginstallationandthewiringandpipingof the indoor and
outdoor units, check for refrigerant leakage, looseness in the power supply
or control wiring, wrong polarity, and no disconnection of one phase in the
supply.
►Usea500-voltmegohmmetertocheckthattheresistancebetweenthepow-
ersupplyterminalsandgroundisatleast1M".
►Donotcarryoutthistestonthecontrolwiring(lowvoltagecircuit)termi-
nals.
Warning:
Donotusetheairconditioneriftheinsulationresistanceislessthan1M".
Insulation resistance
After installation or after the power source to the unit has been cut for an extended
period, the insulation resistance will drop below 1 M"due to refrigerant accumulat-
ing in the compressor. This is not a malfunction. Perform the following procedures.
1. Remove the wires from the compressor and measure the insulation resistance of
the compressor.
2. If the insulation resistance is below 1 M", the compressor is faulty or the resist-
ance dropped due the accumulation of refrigerant in the compressor.
3. After connecting the wires to the compressor, the compressor will start to warm
up after power is supplied. After supplying power for the times indicated below,
measure the insulation resistance again.
• The insulation resistance drops due to accumulation of refrigerant in the com-
pressor. The resistance will rise above 1 M"after the compressor is warmed
up for 12 hours.
(The time necessary to warm up the compressor varies according to atmos-
pheric conditions and refrigerant accumulation.)
• To operate the compressor with refrigerant accumulated in the compressor,
the compressor must be warmed up at least 12 hours to prevent breakdown.
4. If the insulation resistance rises above 1 M", the compressor is not faulty.
Caution:
•The compressor will not operate unless the power supply phase connection
is correct.
• Turnonthepoweratleast12hoursbeforestartingoperation.
-Starting operation immediately after turning on the main power switch can result
in severe damage to internal parts. Keep the power switch turned on during the
operational season.
►Thefollowingsmustbecheckedaswell.
•The outdoor unit is not faulty. LED1 and LED2 on the control board of the outdoor
unit ash when the outdoor unit is faulty.
•Both the gas and liquid stop valves are completely open.
•A protective sheet covers the surface of the DIP switch panel on the control board
of the outdoor unit. Remove the protective sheet to operate the DIP switches eas-
ily.

•After power is supplied, a small clicking noise may be heard from the inside of the
outdoor unit. The electronic expansion valve is opening and closing. The unit is
not faulty.
•A few seconds after the compressor starts, a clanging noise may be heard from
the inside of the outdoor unit. The noise is coming from the check valve due to the
small difference in pressure in the pipes. The unit is not faulty.

8.3.Refrigerantcollecting(pumpdown)
Perform the following procedures to collect the refrigerant when moving the indoor
unit or the outdoor unit.
1Supply power (circuit breaker).
* When power is supplied, make sure that “CENTRALLY CONTROLLED” is not
displayed on the remote controller. If “CENTRALLY CONTROLLED” is dis-
played, the refrigerant collecting (pump down) cannot be completed normally.
* Start-up of the indoor-outdoor communication takes about 3 minutes after the
power (circuit breaker) is turned on. Start the pump-down operation 3 to 4
minutes after the power (circuit breaker) is turned ON.
2After the liquid stop valve is closed, set the SWP switch on the control board of
the outdoor unit to ON. The compressor (outdoor unit) and ventilators (indoor and
outdoor units) start operating and refrigerant collecting operation begins. LED1
and LED2 on the control board of the outdoor unit are lit.
* Only set the SWP switch (push-button type) to ON if the unit is stopped. How-
ever, even if the unit is stopped and the SWP switch is set to ON less than 3
minutes after the compressor stops, the refrigerant collecting operation cannot
be performed. Wait until compressor has been stopped for 3 minutes and then
set the SWP switch to ON again.
3Because the unit automatically stops in about 2 to 3 minutes when the refrigerant
collecting operation is completed (LED1 off, LED2 lit), be sure to quickly close the
gas stop valve. If LED1 is lit and LED2 is off and the outdoor unit is stopped, refrig-
erant collection is not properly performed. Open the liquid stop valve completely,
and then repeat step 2after 3 minutes have passed.
* If the refrigerant collecting operation has been completed normally (LED1 off,
LED2 lit), the unit will remain stopped until the power supply is turned off.
4Turn off the power supply (circuit breaker).
* Note that when the extension piping is very long with large refrigerant amount,
it may not be possible to perform a pump-down operation. When performing
the pump-down operation, make sure that the low pressure is lowered to near
0 MPa (gauge).
Warning:
Whenpumpingdowntherefrigerant,stopthecompressorbeforedisconnect-
ingtherefrigerantpipes.Thecompressormayburstifairetc.getintoit.
