2311.3. Indoor Unit11.3.1. HOW TO FIX INSTALLATION PLATEThe mounting wall is strong and solid enough to prevent it fromthe vibration.The centre of installation plate should be at more than 550 mmat right and left of the wall.The distance from installation plate edge to ceiling should morethan 67 mm.From installation plate left edge to unit’s left side is 47 mm.From installation plate right edge to unit’s right is 73 mm.1. Mount the installation plate on the wall with 5 screws ormore.(If mounting the unit on the concrete wall consider usinganchor bolts.)• Always mount the installation plate horizontally byaligning the marking-off line with the thread and using alevel gauge.2. Drill the piping plate hole with ø70 mm hole-core drill.• Line according to the left and right side of the installationplate. The meeting point of the extended line is thecentre of the hole. Another method is by puttingmeasuring tape at position as shown in the diagramabove. The hole centre is obtained by measuring thedistance namely 150 mm and 125 mm for left and righthole respectively.• Drill the piping hole at either the right or the left and thehole should be slightly slanted to the outdoor side.11.3.2. TO DRILL A HOLE IN THE WALLAND INSTALL A SLEEVE OFPIPING1. Insert the piping sleeve to the hole.2. Fix the bushing to the sleeve.3. Cut the sleeve until it extrudes about 15 mm from thewall.4. Finish by sealing the sleeve with putty or caulkingcompound at the final stage.11.3.3. INDOOR UNIT INSTALLATION1. For the right rear piping2. For the right and right bottom piping: For left side piping, piping connection for liquid should be about126 mm from this line.: For left side piping, piping connection for gas should be about174 mm from this line.: For left side piping, piping connection cable should be about984 mm from this line.CautionWhen the wall is hollow, please be sure to use thesleeve for tube ass’y to prevent dangers caused bymice biting the connecting cable.
