Installation Procedures Installation of Outdoor Unit Selection of installation place Place strong enough to support unit weight, and will not cause vibration and noise. Place where discharged wind and noise do not cause nuisance to the neighbors, and is sufficiently ventilated.
Installation Procedudres 1.Selection of Installation Place (1) Place above the ceiling where have enough space to arrange the unit. (2) Place where the drainage pipe can be arranged well. (3) Place where inlet and outlet air of indoor and outdoor unit will not be blocked. (4) Do not expose the unit to the place with heavy oil or moisture (e.g.kitchen and workshop).
Installation Procedures (3) Install a suspending bolt To support the unit weight ,anchor bolt should be used in the case of already exists ceiling. Fow new ceiling, use flush-in type bolt, built-in type bolt or parts pretared in the field. Before going on installing, adjust space to ceiling.
Installation Procedures 3.Installation of water drainage pipe (1) Install water drainage pipe Pipe diameter shall be equal or larger than that of connecting pipe (Pipe of polythene; size: 25mm; O.D.: 32mm ) Drainpipe should be short, with a downward slope at least 1/100 to prevent air bag from forming. If downward slope of drainpipe cannot be made,lifting pipe shall be installed.
Installation Procedure 4. Installation of Ornament Panel Install ornament panel on indoor unit (1) Check whether indoor unit is horizontal with leveler or polythene pipe filled with water , and check that the dimension of the ceiling opening is correct.
