6.9. Connecting the pipe
CAUTION
Tightenthenutwithatorquewrenchasspecied.Overtightenednutcouldbreak•
after a prolonged period, and may cause a refrigerant leakage. If the leaking refriger-
antisexposedtoadirectame,itmayproduceatoxicgas.
Hold the torque wrench at its grip, keeping it in the right angle with the pipe, in order •
to tighten the nut correctly.
Connectthepipingsothatthecontrolboxcovercaneasilyberemovedforservicing.•
Topreventinowingofwatertothecontrolbox,makesurethatthepipingisproperly•
insulated.
6.9.1. Check the surface of the connection piping, the end face
Usespecialpipecutter.
(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) Protect the pipesbypinching them orwithtape to preventdust, dirt, orwaterfrom
entering the pipes.

6.9.2. Bending pipes
•Thepipesareshapedbyyourhands.Becarefulnottocollapsethem.
•Donotbendthepipesinananglemorethan90°
•Whenpipesarerepeatedlybent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. •
