Indoor Unit Installation Patterns • The indoor unit can not be installed at a position where it directly comes in contact with the floor. • There are two installation patterns shown below as a standard installation specification of the indoor unit. • Be sure to install the indoor unit on a wall that can bear the weight of the unit adequately for any installation pattern. Exposed installation Half concealed installation • For half concealed installation, please refer to page 20 and 21.
English Indoor Unit Installation Drawings • Be sure to install the indoor unit in accordance with the installation instructions below for any installation pattern. Install the indoor unit where there is no obstacle above the unit. Obstacles affect the air current distribution, and an adequate heating or cooling effect cannot be obtained.
Indoor Unit Installation Exposed installation 1. Installing the mounting plate • Decide the installation site with reference to the descriptions on pages 2, 7, and 8. • Before choosing the installation site, obtain user approval. • 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 panel is completely level, and mark the boring points on the wall.
English 2. Refrigerant piping • • • • Create a hole in the refrigerant piping in accordance with the conditions shown in the illustration. The location of the hole is different depending on which side of the pipe is taken out. Allow space around the pipe for an easier indoor unit pipe connection. Maintain an adequate working length for the refrigerant pipe starting from the reference point, as shown in the illustration.
Indoor Unit Installation 4. Shaping the refrigerant pipe • Form the shape of the refrigerant pipe in accordance with the restrictions shown in the illustration. • Protect the open end of the pipe against dust and moisture. Wall Be sure to place a cap. Rain If no flare cap is available, cover the flare mouth with tape to keep dirt or water out. Piping pull-out dimensions Left back piping Right back piping 320 36.

Flaring the pipe end 1) Cut the pipe end with a pipe cutter. 2) Remove burrs with the cut surface facing downward so that the chips do not enter the pipe. 3) Put the flare nut on the pipe. 4) Flare the pipe. 5) Check that the flaring is properly made.
Refrigerant Piping Work 3. Refrigerant piping CAUTION • Use the flare nut fixed to the main unit. (To prevent cracking of the flare nut by aged deterioration.) • To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.) • Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage. Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand.
English 4. Purging air • For the air purging procedures, please refer to the outdoor unit’s installation manual. 5.
