Installation of installation plate
• Using the installation pattern, determine the installation position of the indoor unit, and drill the pipe hole
matching with the position indicated in the installation pattern. When passing the refrigerant pipe through wall
using metal mesh, be sure to use insulation sleeve such as polyvinyl chloride pipe.
n In case of wooden construction (Wide wall)
(1) Determine vertical position of the installation plate by interval (height) between the indoor unit and the ceiling.
(2) Determine the position so that screw hole of installation plate locates at the center of pillar or stud by adjust-
ing left/right position without changing height of the installation plate.
(3) Tighten the screws (accessory parts) after bore preholes with a gimlet in the stud to prevent the crack.
n In case of reinforced concrete construction
(1) After drilling holes with interval by 150mm at the
selected positions on the concrete wall, strike in grip
anchor or hole-in anchor.
(2) Fix the installation plate to the anchor with bolt or nut.
However, when using hole-in anchor, adjust drilling
depth so that screw head-out is 10mm or less.
• Conduit tube may be buried in the concrete wall. Ask the constructor it.
• Before installation of the indoor unit, be sure to check whether the installation plate has been completely
installed.
n In case of rear direction piping
Using the installation pattern, determine the pipe hole position, and drill a pipe hole slightly lowering downward.
