Indoor Unit Installation4Indoor UnitInstallationFig. 3.1-aInstallation Instructions – IndoorUnitPRIOR TO INSTALLATIONBefore installing the indoor unit, refer to thelabel on the product box to make sure that themodel number of the indoor unit matches themodel number of the outdoor unit.Step 1: Select installation locationBefore installing the indoor unit, you mustchoose an appropriate location. The followingare standards that will help you choose anappropriate location for the unit.Proper installation locations meet thefollowing standards: Good air circulation Convenient drainage Noise from the unit will not disturb otherpeople Firm and solid—the location will not vibrate Strong enough to support the weight of theunit A location at least one meter from all otherelectrical devices (e.g., TV, radio, computer)DO NOT install unit in the followinglocations:Near any source of heat, steam, orcombustible gasNear flammable items such as curtains orclothingNear any obstacle that might block aircirculationNear the doorwayIn a location subject to direct sunlightNOTE ABOUT WALL HOLE:If there is no fixed refrigerant piping:While choosing a location, be aware that youshould leave ample room for a wall hole (seeDrill wall hole for connective piping step)for the signal cable and refrigerant pipingthat connect the indoor and outdoor units.The default position for all piping is the rightside of the indoor unit (while facing the unit).However, the unit can accommodate piping toboth the left and right. Page 11
Refer to the following diagram to ensure proper distance from walls and ceiling:15cm (5.9in) or more12cm (4.75in)or more12cm (4.75in)or moreIndoor UnitInstallation2.3m (90.55in) or moreFig. 3.1-bStep 2: Attach mounting plate to wallThe mounting plate is the device on which youwill mount the indoor unit.1. Remove the screw that attaches the mountingplate to the back of the indoor unit.2. Place the mounting plate against the wallin a location that meets the standards inthe Select Installation Location step. (SeeMounting Plate Dimensions for detailedinformation on mounting plate sizes.)3. Drill holes for mounting screws in places that: have studs and can support the weight ofthe unit correspond to screw holes in the mountingplate4. Secure the mounting plate to the wall withthe screws provided.5. Make sure that mounting plate is flat againstthe wall.Step 3: Drill wall hole for connective pipingYou must drill a hole in the wall for refrigerantpiping, the drainage pipe, and the signal cablethat will connect the indoor and outdoor units.1. Determine the location of the wall hole basedon the position of the mounting plate. Referto Mounting Plate Dimensions on thenext page to help you determine the optimalposition. The wall hole should have a 65mm(2.5in) diameter at least, and at a slightlylower angle to facilitate drainage.2. Using a 65-mm (2.5in) core drill, drill a hole inthe wall. Make sure that the hole is drilled ata slight downward angle, so that the outdoorend of the hole is lower than the indoor endby about 5mm to 7mm (0.2-0.275in). This willensure proper water drainage. (See Fig. 3.2)3. Place the protective wall cuff in the hole. Thisprotects the edges of the hole and will helpseal it when you finish the installation process.NOTE FOR CONCRETE OR BRICK WALLS:If the wall is made of brick, concrete, or similarmaterial, drill 5mm-diameter (0.2in-diameter)holes in the wall and insert the sleeve anchorsprovided. Then secure the mounting plate tothe wall by tightening the screws directly intothe clip anchors. Page 12 CAUTIONWhen drilling the wall hole, make sure toavoid wires, plumbing, and other sensitivecomponents.

Step 4: Prepare refrigerant pipingThe refrigerant piping is inside an insulatingsleeve attached to the back of the unit. You mustprepare the piping before passing it through thehole in the wall. Refer to the Refrigerant PipingConnection section of this manual for detailedinstructions on pipe flaring and flare torquerequirements, technique, etc.Indoor UnitInstallation1. Based on the position of the wall hole relativeto the mounting plate, choose the side fromwhich the piping will exit the unit.2. If the wall hole is behind the unit, keep theknock-out panel in place. If the wall hole is tothe side of the indoor unit, remove the plasticknock-out panel from that side of the unit.(See Fig. 3.3 ). This will create a slot throughwhich your piping can exit the unit. Useneedle nose pliers if the plastic panel is toodifficult to remove by hand.3. Use scissors to cut down the length of theinsulating sleeve to reveal about 15cm (6in)of the refrigerant piping. This serves twopurposes: To facilitate the Refrigerant PipingConnection process To facilitate Gas Leak Checks and enableyou to check for dents4. If existing connective piping is alreadyembedded in the wall, proceed directly tothe Connect Drain Hose step. If there is noembedded piping, connect the indoor unit’srefrigerant piping to the connective pipingthat will join the indoor and outdoor units.Refer to the Refrigerant Piping Connectionsection of this manual for detailed instructions.5. Based on the position of the wall holerelative to the mounting plate, determine thenecessary angle of your piping.6. Grip the refrigerant piping at the base of thebend.7. Slowly, with even pressure, bend the pipingtowards the hole. Do not dent or damage thepiping during the process.NOTE ON PIPING ANGLERefrigerant piping can exit the indoor unit fromfour different angles: Left-hand side Left rear Right-hand side Right rearRefer to Fig. 3.4 for details.Knock-out PanelFig. 3.3Fig. 3.4CAUTIONBe extremely careful not to dent or damage the piping while bending them away from theunit. Any dents in the piping will affect the unit’s performance. Page 14
