5 Outdoor Unit Installation Outdoor Unit Installation Instructions √ √ √ √ √ The area must be free of combustible gases and chemicals. The pipe length between the outdoor and indoor unit may not exceed the maximum allowable pipe length. If possible, DO NOT install the unit where it is exposed to direct sunlight. If possible, make sure the unit is located far away from your neighbors’ property so that the noise from the unit will not disturb them.

(See Fig. 5.12) 1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit. 2.
6 Drainpipe Installation The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage. NOTE ON DRAINPIPE INSTALLATION • CAUTION Insulate all piping to prevent condensation, which could lead to water damage. • If the drainpipe is bent or installed incorrectly, water may leak and cause a water-level switch malfunction. • In HEAT mode, the outdoor unit will discharge water.
3. Using a 2.5” (65-mm) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 0.5” (12mm). This will ensure proper water drainage (See Fig. 6.5). Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process. The unit with pump. 1. Remove the test cover. Fill the water pan with 2.11 quart of water.
7 Refrigerant Piping Connection Safety Precautions WARNING • Refrigerant Piping Connection All field piping must be completed by a licensed technician and must comply with the local and national regulations. • When the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage.
Refrigerant Piping Connection Instructions CAUTION The branching pipe must be installed horizontally. An angle of more than 10° may cause malfunction. • DO NOT install the connecting pipe until both indoor and outdoor units have been installed. • Insulate both the gas and liquid piping to prevent water leakage. • Step1: Cut pipes 1. Measure the distance between the indoor and outdoor units. 2. Using a pipe cutter, cut the pipe a little longer than the measured distance.
6. Place flaring tool onto the form. 7. Turn the handle of the flaring tool clockwise until the pipe is fully flared. Flare the pipe in accordance with the dimensions shown in table 7.2.

8 Wiring Safety P recautions WARNING DO NOT connect the unit to the power source until all wiring and piping is completed. • Make sure that you do not cross your electrical wiring with your signal wiring. This may cause distortion and interference. • • Connect the out door wires before connecting the indoor wires. • Make sure you ground the unit. The grounding wire should be located away from gas pipes, water pipes, lightning rods, telephone wires or other grounding wires.

Using wire strippers, strip the rubber jacket from both ends of the signal cable to reveal approximately 15cm (5.9”) of wire. c. Strip the insulation from the ends. d. Using a wire crimper, crimp u-lugs on the ends. NOTE: When connecting the wires, strictly follow the wiring diagram found inside the electrical box cover. 2.
Using the wire control to set external static pressure (some models) • • You can use the unit’s automatic airflow adjustment function to set external static pressure. CAUTION • After 3 to 6 minutes, the air conditioning unit stops operating once automatic airflow adjustment has finished. Automatic airflow adjustment is the volume of blow-off air that has been automatically adjusted to the quantity rated. 1. Make sure the test run is done with a dry coil.

Wait for 5 minutes, then check that there has The outdoor unit does not need vacuuming. been no change in system pressure.
Note On Adding Refrigerant CAUTION • Refrigerant charging must be performed after wiring, vacuuming, and the leak testing. • DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so can damage the unit or impact it’s functioning. • Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate refrigerant is used. • Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
