Be careful not to bend ordamage the connection pipe. Do not overtighten the joint nut. Overtightening the jointnut can cause leakage.Hex nut diameter6mm9.52mm12mm16mm19mm15-2031-3550-5560-6570-75Tightening torque (N·m)If you find the electrical wiring is of insufficient length for correct installation, please contact anauthorized service shop.• The electric wiring must be correctly connected. Incorrect connection can cause spare parts tomalfunction.• Tighten the terminal screw correctly.• After tightening the screw, lightly pull the wire to confirm that it is firmly in place.• If the ground wire is incorrectly connected, there is danger of electric shock.• The cover plate must be attached, and the connection must be tight. Incorrect installation canlet moisture enter in, which increases the danger of fire or electric shock.• The piping can extend out from the right, right rear,left, or left rear.1. When routing the piping and wiring from the left orright side of the indoor unit, you can cut off theframe tailings if necessary. (Show in Fig.7)(1) Cut off tailings 1 when routing the wiring only;(2) Cut off tailing 1 and tailing 2 when routing boththe wiring and piping.2. Remove the piping from the body case, wrap thepiping electrical wiring and water pipe with tapeand pull them through the piping hole. (See Fig.8)3. Hang the mounting slots for the indoor unit on theupper tabs of the rear panel and check if it iscorrectly attached. (See Fig.9)4. The installation height should be 2.5m or abovethe floor.1. Align the center of the piping flare with the valve.2. Screw in the flare nut by hand and then tighten the nutwith a spanner and torque wrench to the specified torque.Indoor unit installationInstall the connection pipe
