If theairconditioneristransferredto theothers, thismanualshould be tranferredtogether.
!WARNING
The installation orthe maintenance shouldbe performed bythe authorized agency. Or the
non-specialized operation willcausewaterleakage,electricshockorfire etcaccidents.
The installation shouldbe executedasperthe manual, orthe faultyinstallation willcause
waterleakage, electricshockorfire etcaccidents.
Please installtheunit at thespacewhich can beartheweight. Or the unit willdropdown to
cause thehuman injury.
The installation shoulddefend against the typhoon, andthe earthquakeetc.Abnormal
installation willcausethe unit falldown.
Use thecorrect cableandmake reliable earthing. Fixtheterminalfirmlyand theloose
connection willcause heatingorfire etcaccident.
The wiringshould bein shape and can not be raised. Beearthedfirmlyand can not beclipped
bythe electricboxcoverorthe otherplate. The incorrect installation willcause heating orfire.
When setting ortransferring theunit, thereshouldnot be otherairinto the refrigerant system
except forR410A.The gasmixture willcause the abnormalhigh pressurewhich willcause
breakorhumaninjury etcaccidents.
When installation, please usethe accessorieswith the unit orthespecialparts, orit willcause
waterleakage, electricshock, fire, refrigerant leakage etcaccidents.
Don't lead the waterdrainagepipe into the drainage groove with thepoisonousgas, such as
sulphur. Orthe poisonousgaswillenterindoor.
In installation orafterinstallation, please confirm if there isrefriegerant leakage, please take
measuresforventilation. The refrigerant willcause poisonousgasasmeeting fire.
Don't installtheunit at the placewhere there maybe flammablegasleakage. Incase the gas
leaksand gatheraround theunit, it willcause fire.
The drainage pipeshould be installedasperthe manualtoconfirm the fluent drainage. Also
take measuresforheat insulation against dew drop. Incorrect waterpipeinstallation willcause
waterleakage even and makethe thingswet.
Forthe liquid pipe and thegaspipe, take measuresforheat insulation too. If thereisno heat
insulation,the dew drop willwet the things.
Before installation, please read "Safetyprecaution"carefullyto confirm thecorrect installation.
The mentioned precaustion includes"!WARNING"and "!CAUTION".Theprecausioncaused
death orheavyinjuryforfaultyinstallation willbe listed in "!WARNING". Even the cautions
listed in "!CAUTION"also maycause seriousaccident. So bothof them are relatedto the
safety, and should be executed severely.
Afterinstallation, perform atrialandconfirm everything normal, then introducethe operation
manualto the user. Besides, put the manualto theuserand askthemto preserve itcarefully.

When charging refrigerant, the refrigerant must be taken out asliquidstate from the tank.
When installing indoorunit, outdoor, powercable and connecting wire, leave them at least 1m
awayfromthe TVset ortheradioagainst interference forthe imageorthe noise.

(1)Beforeinstallation
1)Beforeinstallation, checkif the model, powersupply, pipe, wiresand partspurchased
respectively are correct.
2)Checkif the indoorsand outdoorscan becombined asthe following.

Air-conditionercan't be
installedintheplacewith
inflammable gas. Or it
willcause firehazard.
The unitshouldbeinstalled at the
strong enough place. Oritwillcause
vibration and noise.
The unit should be
installedat theplace
wherethe cold/hotairor
noise willnot interfere
the neighbours.
The unit isbetternot be installed
at the below places, orit will
cause damage.
The placewhere there is
corrosive gas(spa areaetc).
The placeblowing saltyair
(seaside etc).
Exsitsthestrong coalsmoke.
The placewithhigh humidity.
The placewhere there isdevice
emittingHertzian waves.
Theplacewherevoltage changes
greatly.
In transportation, pleasedon't dismantle the packaging, and movethe unit tothe installation
location ascloselyaspossible.
If the packagingmust be dismantled, hang up the unit with ropeagainst damage.
Don't hang theunit only at two points. When hangingthe unit, don't sit on the unit. Theunit
shouldbe upright.
When removing theunit withthe forklift, put the forkinto the specialhole at bottomof theunit.
When being hanged, therope shouldbe 4 piecesof steelcable withover6mmdiameter.
Put the cushionat thecontact section betweensteelcable and theunit against thedistortion
ordamage.

A.Refrigerantpipeconnection When fastening and loosingthe nut,
operate with double spanners,
becauseonlyone spannercannot
execute firmly.
If threading the nut asnot aiming
at the center, the screw thread will

leakage.
spanner
spanner
connector
nut
Toensure theefficiency, the pipe shouldbe
asshortaspossible.
Daubthe refrigerant oilon the connectorand
the flare nut.
When bending thepipe, thebending semi-
diametershouldbe aslarge aspossible
against thepipe beingbroken orbent.
When connecting the pipe, aim at the center
to thread thenut byhand and tightenit with
the double spanners.
Don't let theimpuritysuchassand, wateretc
into the pipe.
Pipeconnectionmethod:
1. When welding the connectorwith hard solder, charge nitrogeninto the pipe against oxidation.
Orthe oxygen filmin the pipe willclogthe capillaryand the expansion valve, even caue the
deathyaccident.
2. The refrigerant pipeshould be clean. If the waterand the otherimpurityenterthe pipe,
charge the nitrogento clean thepipe. The nitrogenshould flow underthe pressure of about
0.5Mpa and when charging the nitrogen, stop up the end of the pipe byhand toenhance the
pressureinthe pipe, then loose the hand (meanwhilestopup the otherend).
3. The piping installation shouldbe executedafterthestop valvesare closed.
4. Before welding the valve and thepipes,usethe wet cloth tocooldown the valve and the
pipes.
5. When the connection pipeand the branchpipe need to be cut down, please use thespecial
shears and cannot use the saw.
Cautions inpipinginstallation:
Pipematerialandspecs selection
1. Please select the refrigerant pipe of the below material.
Material: the phosphoric oxidizeseamlesscopper pipe, model: C1220T-1/2H (diameter is
over 19.05); C1220T-0(diameter isbelow 15.88).
2. Thicknessand specs:
Confirm the pipe thicknessand specsaccording to the pipe selection method(the unit iswith
R410A, if the pipe over 19.05 is0-type, the pressure preservation willbe bad, thus it must be
1/2H type and overthe min. thickness.
3. The branch pipe must be fromAirwell.
4. When installing the stop valve, refer to the relative operation instruction.
5. The pipe installation shouldbe in the allowablerange.
6. The installation of branch pipe and gather pipe shouldbe performed according to the relative
manual.
