[. . . ] Place, nearby a power receptacle, with enough space around. Place where the distance of more than lm from televisions, radios, wireless apparatuses and fluorescent lamps can be left. Do not make the air flow blows directly to the bed when installing the indoor unit. Place, which is less affected by rain or direct sunlight and is sufficiently ventilated. Place, possible to bear the unit, where vibration and noise are not increased. [. . . ] 2) L component installation L shape component (accessory) Do not make gap between the component and the unit, fasten the L-shape component with the unit with the bolts (fig. After making sure the unit keeps vertical, fasten the L-shape onto the floor with the bolts (fig. Piping connection Connecting method To bent a pipe, give the roundness as large as possible not to crash the pipe. When connecting pipe, hold the pipe center to center then screw nut on by hand, refer to Fig. Be careful not to let foreign matters, such as sands enter the pipe. Forced fastening without careful centering may damage the threads and cause a leakage of gas.

According to the piping method, connect the piping on indoor unit with union of connection pipe. Arrange the piping as per the wall hole and bild drain hose connecting electric cable and piping together with polyethylene tape. Insert the bound piping connecting electric cable and drain hose through wall hole to connect with outdoor unit. According to the hole location, install the connection pipe and tie up the soft drain pipe, connection cable, and connection pipe with the polyethylene adhesive tape, and then drill through the prepared hole so as to connect with the outdoor unit.

There should be a slope when arrange drain hose. If humidity is high, drain pipe(especially in room ) must be covered with installation material. 3. Piping connection of the outdoor unit Purging method Push the air out of the indoor unit and piping as followes: (1) Remove the valve cap on 2-way valve in outdoor unit. (2) Loosen by 1~2 circle the flare nut of gas pipe, which is conneted to 3-way valve. (3) Loosen 2-way valve by 90o using hexagon wrench, and after approx. Gas comes out through flare nut on wide pipe. If no gas is discharged, tighten flare nut with specified torque. (4) Open 2-way and 3-way valves using specified torque. (5) Tighten the caps on the valves with specified torque.

Brand new unit is charged 80g more refrigerant than regulated werght. [. . . ] There is not power plug with the type of 18k, and there is not power cable with the type of 24k. When installation air conditioner in a wet place , try to use a circuit breaker against current leakage. For installation in other places, use circuit breaker as far as possible. 2. Piping cutting and flaring Be sure to carry out deburring after cutting with a pipe cutter. Insert flaring tool to make a flare.
