The following should always be observed for safety
• Please provde an exclusve crcut for the ar condtoner and make
sure that no other electrcal applances are connected to t.
• Be sure to read <The followng should always be observed for
safety> before nstallng the ar condtoner.
• Be sure to observe the cauton specfed here as they nclude
mportant tems related wth safety.
• After readng ths manual, be sure to keep t together wth the
Instructon manual n a handy place on the customer's ste.
Warning
• Dot not nstall the unt by yourself (customer).
Incomplete nstallaton could cause njury due to fre, electrc
shock, the unt fallng or leakage of water. Consult the dealer from
whom you purchased the unt or specal nstaller.
• Install the unt securely n a place whch can bear the weght
of the unt.
When nstalled n an nsuffcent strong place, the unt could fall
and cause njury.
• Use the specfed wres to connect the ndoor and outdoor
unts securely and attach the wres frmly to the termnal
block connectng sectons so that the stress of the wres s not
appled to the sectons.
Incomplete connectng and fxng could cause fre.

1 Safety nstructons
• Do not use ntermedate connecton of the power cord or the
extenson cord and do not connect many devces to one AC
outlet.
It could cause a fre or an electrc shock due to defectve contact,
defectve nsulaton ,exceedng the permssble current, etc.
• Check that the refrgerant gas does not leak after nstallaton
has completed.
If refrgerant gas leaks ndoors, and comes nto contact wth the
fre of a fan heater, space heater, stove, etc., harmful substances
wll be generated.
• Perform the nstallaton securely referrng to the nstallaton
manual.
Incomplete nstallaton could cause a personal njury due to fre,
electrc shock, the unt fallng or leakage of water.
• Perform electrcal work accordng to the nstallaton manual
and be sure to use an exclusve crcut.
If the capacty of the power crcut s nsuffcent or there s
nsuffcent electrcal work, t could result n a fre or an electrc
shock.
• Attach the electrcal cover to the ndoor unt and the servce
panel to the outdoor unt securely.
If the electrcal cover n the ndoor unt and/or the servce panel n
the outdoor unt are not attached securely, t could result n a fre
or an electrc shock due to dust water, etc.

• Be sure to cut off the man power n case of settng up the
ndoor electronc control P. C. Board or wrng works.
It could cause an electrc shock.
• The applance shall be nstalled n accordance wth natonal
wrng regulatons.
• When nstallng or relocatng the unt, make sure that no
substance other than the specfed refrgerant (R410A)
enters the refrgerant crcut.
Any presence of foregn substance such as ar can cause abnormal
pressure rse or an exploson.
• Perform earthng.
Do not connect the earth wre to a gas ppe, water ppe, lghtnng
rod or telephone earth wre. Defectve earthng could cause an
electrc shock.
• Do not nstall the unt n a place where an nflammable gas
leaks.
If gas leaks and accumulates n the area surroundng the unt, t
could cause an exploson.
• Fasten a flare nut wth torque wrench as specfed n ths
manual.
When fastened too tght, a flare nut may break after a long perod
and cause a leakage of refrgerant.
• Install an earth leakage breaker dependng on the nstallaton
place (where t s humd).

5.2 Flarng work
Main cause of gas leakage is defect in flaring work. Perform flaring work correctly in the following
procedure.
1. Ppe cuttng
• Cut the cooper ppe correctly wth ppe cutter.
2. Burrs removal
• Completely remove all burrs from the cut cross secton of the ppe.
• Put the end of the copper ppe downward to prevent burrs from droppng n the ppe.
3. Puttng nut on
• Remove flare nuts attached to ndoor and outdoor unts, then put them on ppe havng completed
burr removal.
(Not possble to put them on after flarng work).
• Flare nut for R410A ppe may dffer from R22 ppe dependng on the dameter of ppe.
4. Flarng work
• Perform flarng work usng flarng tool as shown below.

5. Check
• Compare the flared work wth the fgure below.
• If flare s noted to be defectve, cut off the flared secton and perform flarng work agan.

Note: Fasten a flare nut with a torque wrench as specified in the table below. When
fastened too tight, a flare nut may be broken after a long period and cause a leakage of
refrigerant.
1. Indoor unt connecton
• Connect both lqud ppe and gas ppe to ndoor unt.
- Apply a thn coat of refrgeraton ol to the seat surface of ppe.
- For connecton, algn the center of both ppe and unon, then tghten the frst 3 to 4 turns n flare
nut by hand.
- For tghtenng the unon part of the ndoor unt sde, use the table below as a standard and tghten
the flare nut wth two wrenched. Excessve tghtenng damages the flared secton.

• Connect ppe to the ppe jont part of the stop valve n the same method as the ndoor unt.
- For tghtenng, use the same tghtenng torque appled for ndoor unt and tghten the flare nut
wth torque wrench or spanner.

5.4 Purging procedures • leak test
1. Purgng procedures
1. Connect the refrgerant ppes (both lqud ppe and gas ppe) between the ndoor unt and the
outdoor unt.
2. Remove the servce port cap of the stop valve on the gas ppe sde of the outdoor unt. (The stop
valve wll not work n ts ntal state fresh out of the factory [totally closed wth cap on].)
3. Connect the gauge manfold valve and vacuum pump to the servce port of the stop valve on the
gas ppe sde of the outdoor unt
4. Run the vacuum pump. Vacuumze for more than 15 mnutes.
5. Check the vacuum wth the gauge manfold valve, then close the gauge manfold valve and stop
the vacuum cap.
6. Leave t as s for one or two mnutes. Make sure the ponter of the gauge manfold valve remans
n the same poston. Confrm that the pressure gauge shows -0.101MPa or -760mmHg.
7. Remove the gauge manfold valve quckly from the servce port of the stop valve.

8. After refrgerant ppes are connected and evacuated, fully open all stop valves on both sdes of
gas ppe and lqud ppe.
9. Ppe length up to 15m, no gas charge s needed.
Ppe length exceedng 15m, charge the prescrbed amount of gas.
10.Tghten the cap to the servce port to obtan the ntal status.
11. Retgten the cap.
