[. . . ] Swing the indoor unit to right and left to confirm that it is firmly hooked on the installation plate. While pressing the indoor unit onto the wall, hook it at the lower part on the installation plate. Pull the indoor unit toward you to confirm that it is firmly hooked on the installation plate. Hook here a Installation plate Hook Press (unhook) · For detaching the indoor unit from the installation plate pull the indoor unit toward you while pushing the bottom up at the specified places. Push Push Drainage 1. Run the drain hose at a downward sloped angle. NOTE · Hole should be made at a slight downward slant on the outdoor side. Do not route the drain hose upwards. Do not form the drain hose into a waved shape. 50 mm or more Do not put the drain hose end into water. Do not put the drain hose end in a drainage ditch. 2. 3. Put water in the drain pan and make sure that the water is being drained outside. When connecting extension drain hose, insulate the connection part of extension drain hose with shield pipe. Shield pipe Drain hose Inside the room Extension drain hose CAUTION Install the drain pipe for proper drainage. Improper drainage can result in water dripping inside the room. This air conditioner has been designed to drain water collected from condensation which forms on the back of the indoor unit, to the drain pan. Therefore, do not locate the power cord and other parts at a height above the drain guide. Wall Drain guide Space for pipes ­ 56 ­ 10-4. Installation of Outdoor Unit Installation Location A place which provides enough space around the outdoor unit as shown in the diagram. If a centralized drain is required when installing the unit on a balcony or wall, follow the steps below to drain off the water. Proceed with water-proofing by installing the water-proof rubber caps j in the 2 elongated holes on the base plate of the outdoor unit. [How to install the water-proof rubber caps] 1) Place four fingers into each cap, and insert the caps into the water drain holes by pushing them into place from the underside of the base plate. 2) Press down on the outer circumferences of the caps to ensure that they have been inserted tightly. (Water leaks may result if the caps have not been inserted properly, if their outer circumferences lift up or the caps catch on or wedge against something. ) 2. Install the drain nipple i and a commercially available drain hose (with 16 mm inside diameter), and drain off the water. (For the position where the drain nipple i is installed, refer to the installation diagram of the indoor and outdoor units. ) · Check that the outdoor unit is horizontal, and route the drain hose at a downward sloped angle while ensuring that it is connected tautly. j Water-proof rubber caps (supplied with the outdoor unit) Base plate i Drain nipple Base plate i Drain nipple Commercially available drain hose Do not use ordinary garden hose, which can flatten and prevent water from draining. ­ 57 ­ Refrigerant Piping Connection Flaring 1.

The copper pipe gauge is useful for adjusting projection margin size. Tighten the connection Align the centers of the connecting pipes and tighten the flare nut as much as possible with your fingers. [. . . ] When there is the heating part near the electric parts box, a fire may generate. Be sure to set the heating part on the outdoor unit base plate at the fan room side or near it. (within 20cm from the outdoor unit base plate) * Be careful that the cord heater does not hit the fan. Fix the cord heater without any loosening or sag. [. . . ]
