8 ■EnglishIndoor Unit Installation1. Installing the mounting plate• The mounting plate should be installed on a wall which can support the weight of the indoor unit.1) Temporarily secure the mounting plate to the wall, make sure that the plate is completely level, and mark the boringpoints on the wall.2) Secure the mounting plate to the wall with screws.Recommended mounting plate retention spots and dimensions2. Boring a wall hole and installing wall embedded pipe• For walls containing metal frame or metal board, be sure to use a wallembedded pipe and wall cover in the feed-through hole to prevent possibleheat, electrical shock, or fire.• Be sure to caulk the gaps around the pipes with caulking material to preventwater leakage.1) Bore a feed-through hole of 3-1/8 inch (80mm) in the wall so it has a downslope toward the outside.2) Insert a wall pipe into the hole.3) Insert a wall cover into wall pipe.4) After completing refrigerant piping, wiring, and drain piping, caulk pipe holegap with putty.3. Inter-unit wiring1) Open the front panel, then open the service lid.2) Pass the inter-unit wire from the outdoor unit through the feed-through wall hole and then through the back of the indoor unit. Pullthem through the front side. Bend the ends of tie wires upward foreasier work in advance. (If the inter-unit wire ends are to be strippedfirst, bundle wire ends with adhesive tape.)3) Press the bottom frame of the indoor unit with both hands to set it onthe mounting plate hooks. Make sure the wires do not catch on theedge of the indoor unit.* The removed pipe port cover can bekept in the mounting plate pocket.
