CAUTION
Topreventbreakingofthepipe,avoidsharpbends.
Ifthepipeisbentrepeatedlyatthesameplace,itwillbreak.
• Thepipesareshapedbyyourhands.Becarefulnottocollapsethem.
• BendR70mmormorewithapipebender.
• 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.
• Whenbendingthepipe,donotbenditas

cuttheinsulatingpipewithasharpcutter
asshownonthe right,andbendit after
exposingthepipe.Afterbendingthepipe

CAUTION
BesuretoInstallthepipeagainsttheportontheindoorunitcorrectly.Ifthecentering
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.
Connectthepipingsothatthecontrolboxcovercaneasilyberemovedforservicing
whennecessary.
Inordertopreventwaterfromleakingintothecontrolbox,makesurethatthepiping
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
