6 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.

7 Refrigerant Piping Connection Safety Precautions WARNING Refrigerant Piping Connection • All field piping must be handled by a licensed technician and must comply with all local and national regulations. • If 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.
4. Remove PVC tape from ends of pipe when ready to perform flaring work. 5. Clamp flare form onto the end of the pipe. The end of the pipe must extend beyond the flare form. NOTE: Use both a spanner and a torque wrench when connecting or disconnecting pipes to/from the unit to prevent twisting or other damage. Flare form Fig. 7.7 Pipe Fig. 7.4 6. Place flaring tool onto the form. 7. Turn the handle of the flaring tool clockwise until the pipe is fully flared.
8 Wiring Safety Precautions WARNING • • • • • • Wiring • • Be sure to disconnect the power supply before performing any electrical work. All electrical wiring must be in accordance with all local and national regulations. Electrical wiring must be done by a qualified technician. Improper connections may lead to electrical malfunction, injury, and fire. An independent circuit and circuit breaker must be used for this unit. DO NOT power another appliance through the same circuit breaker.

Using wire strippers, strip the rubber jacket from both ends of signal cable to reveal about 15cm (6”) of the wire leads inside. c. Strip the insulation from the ends of the wire leads. d. Using a wire crimper, crimp u-lugs on the ends of the wires (Ensuring solid contact). 5. Insulate unused wires with electrical tape.
Wiring Figure CAUTION Plug the connective cables to the corresponding terminals, as shown, with their matching numbers on the terminal block of the indoor and outdoor units. For example, in the US models shown in the following diagram, Terminal (A) of the outdoor unit must connect with Terminal (A) on the indoor unit, through the same colored wire lead, without any inversions along the way.
NOTE: Please refer to the following figures if end-users wish to perform their own wiring.

CAUTION After confirmation of the above conditions, follow these guidelines when performing wiring: • Always have an individual dedicated power circuit specifically for the air conditioner. Always follow the circuit diagram posted on the inside of the control cover. • Screws that fasten the wiring inside the casing of the electrical terminals may come lose during transporation. Because loose screws can cause wire burn-out, check that the screws are tightly fastened and that all connections are secure.
end of the refrigerant pipes. The leak must be located, and the leaking nut must be tightened properly, before re-vacuuming the circuit. 9. If the vacuum is achieved, close the manifold valve at the low (blue) side on your gauge manifold first, and shut the vacuum pump off. Leave the gauge manifold set and the hoses connected, and recheck the vacuum reading 15 minutes later to ensure there is no vacuum loss. (Very small increases in vacuum level is normal). 10. Circuit A is now dry and free of contaminants.

6. Set the refrigerant container onto an electronic charging scale, and record the weight (or zero-out the scale, depending on the scale used). 7. Start all indoor units attached to the system in cooling mode, and lower the set points on each of their controllers to the minimum setting, so that the system will not shut off during the procedure. 8. Refrigerant can now be added to the system.

Note On Adding Refrigerant CAUTION • Refrigerant charging must be performed after wiring, vacuuming, and 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 only the appropriate refrigerant (R410a) is used. • Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
Test Run Before Test Run A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test: a) Indoor and outdoor units are properly installed. b) Piping and wiring are properly connected. c) No obstacles near the inlet and outlet of the unit that might cause poor performance or product malfunction. d) Refrigeration system does not leak. e) Drainage system is unimpeded and draining to a safe location.
Function of Automatic Wiring/Piping Correction 11 Automatic Wiring/Piping Correction Function The newest models now feature automatic correction of wiring/piping errors. Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED displays "CE”, indicating that this function is working. Approximately 5-10 minutes after the switch is pressed, the "CE" disappears, meaning that the wiring/piping error is corrected and that all wiring/piping is properly connected.
