CAUTION
Tightenthearenutswithatorquewrenchusingthespeciedtighteningmethod.Oth-
erwise,thearenutscouldbreakafteraprolongedperiod,causingrefrigeranttoleak
andgeneratehazardousgasiftherefrigerantcomesintocontactwithaame.
6.6.1. Flaring
UsespecialpipecutterandaretoolexclusiveforR410A.
(1) Cuttheconnectionpipetothenecessarylengthwithapipecutter.
(2) Holdthepipedownwardsothatcuttingswillnotenterthepipeandremoveanyburrs.
(3)
Inserttheare nut (always use the are nutattachedtothe indoor unit(s) and outdoor
unitrespectively)ontothepipeandperformtheareprocessingwithaaretool.Usethe
specialR410Aaretool,ortheconventionalaretool.Leakageofrefrigerantmayresultif
otherarenutsareused.
(4) Protectthepipes bypinchingthem orwithtape topreventdust, dirt, orwaterfrom

6.6.2. Bending pipes
• Ifpipesareshapedbyhand,becarefulnottocollapsethem.
• Donotbendthepipesinananglemorethan90°.
• Whenpipesarerepeatedlybendorstretched,thematerialwillharden,makingitdifcult
tobendorstretchthemanymore.
• Donotbendorstretchthepipesmorethan3times.
CAUTION
•Topreventbreakingofthepipe,avoidsharpbends.
•Ifthepipeisbentrepeatedlyatthesameplace,itwillbreak.
6.6.3. Pipe connection
CAUTION
•Besuretoinstallthepipeagainsttheportontheindoorunitcorrectly.Ifthecenter-
ingis improper,the are nut cannot tighten smoothly. If theare nut is forcedto
turn,thethreadswillbedamaged.
•Donotremovethearenutfromtheindoorunitpipeuntilimmediatelybeforecon-
nectingtheconnectionpipe.
•Holdthetorquewrenchatitsgrip,keepingitintherightanglewiththepipe,inorder
totightenthearenutcorrectly.
•Tightenthe are nuts with a torque wrench using the specied tightening method.
Otherwise,thearenutscouldbreakafteraprolongedperiod,causingrefrigerantto
leakandgeneratehazardousgasiftherefrigerantcomesintocontactwithaame.
CAUTION
•Connectthepipingsothatthecontrolboxcovercaneasilyberemovedforservic-
ingwhennecessary.
•Inordertopreventwaterfromleakingintothecontrolbox,makesurethatthepip-
ingiswellinsulated.
Whentheflarenutistightenedproperlybyyourhand,holdthebodysidecouplingwitha
wrench,thentightenwithatorquewrench.(Seethetablebelowfortheflarenuttightening
