[. . . ] If the connecting pipe is laid the indoor unit on the installation plate at the upper exceeding 43 mm above the wall surface, the indoor hooks. Swing the indoor unit to right and left to confirm that connecting pipe, make sure to use a spring bender so it is firmly hooked up on the installation plate. While pressing the indoor unit onto the wall, hook it at the lower part on the installation plate. Pull the Bend the connection pipe within a radius of 30 mm. indoor unit toward you to confirm that it is firmly To connect the pipe after installation of the unit (figure) hooked up on the installation plate.

After passing the connecting pipe through the pipe hole, connect the connecting pipe to the auxiliary pipes and wrap the facing tape around them. Push Push CAUTION · Bind the auxiliary pipes (two) and connecting cable with facing tape tightly. In case of leftward piping and rear-leftward piping, bind the auxiliary pipes (two) only with facing tape. Indoor unit Auxiliary pipes Connecting cable Installation plate Fig. 8-4-18 · Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit. · Carefully connect the auxiliary pipes and connecting pipes to each other and cut off the insulating tape wound on the connecting pipe to avoid double-taping at the joint, moreover, seal the joint with the vinyl tape, etc. 8-4-20 CAUTION Arrange the drain pipe for proper drainage from the unit. Improper drainage can result in dew-dropping. This air conditioner has the structure designed to drain water collected from dew, which forms on the back of the indoor unit, to the drain pan. Therefore, do not store the power cord and other parts at a height above the drain guide. Wall Drain guide Strong wind Space for pipes Fig. Cut the pipe with a pipe cutter.

It is therefore necessary to firmly tighten the flare pipe connecting sections (which connect the indoor and outdoor units) up to the specified tightening torque. Incorrect connections may cause not only a gas leakage, but also damage to the refrigerant cycle.
