7 Refrigerant Piping Connection Safety Precautions WARNING Refrigerant Piping Connection • All field piping must be completed by a licensed technician and must comply with 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.
4. Remove the PVC tape from the ends of the NOTE: Use both a spanner and a torque wrench pipe when you're ready to perform the flaring when connecting or disconnecting pipes to/from work. the unit. 5. Clamp the flare form on the end of the pipe. The end of the pipe must extend beyond the flare form. Flare form Pipe Fig. 7.4 6. Place the 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 working on the unit. All electrical wiring must be done according to local and national regulations. Electrical wiring must be done by a qualified technician. Improper connections may cause electrical malfunction, injury, and fire. An independent circuit and single outlet must be used for this unit. DO NOT plug another appliance or charger into the same outlet.

Wiring Figure CAUTION Connect the connective cables to the terminals as identified with their respective matched numbers on the terminal block of the indoor and outdoor units. For example, see the following US models: Terminal L1(A) on the outdoor unit must connect with terminal L1 on the indoor unit. NOTE: If the client wants to perform the wiring himself, refer to the following figures. Run the main power cord through the lower line-outlet of the cord clamp.
NOTE: If the client wants to perform the wiring himself, refer to the following figures.
Model E Model F Model G One-five models: Wiring Model A Model C Page 18 Model B Model D
Model E Model F Model G CAUTION Page 19 Wiring After the confirmation of the above conditions, prepare the wiring as follows: • Never fail to delegate an individual power circuit specifically for the air conditioner. For the method of wiring, use the circuit diagram posted on the inside of the control cover as a guide.
9 Air Evacuation Safety Precautions CAUTION • Use a vacuum pump with a gauge reading lower than -0.1 MPa and an air discharge capacity above 40 L/min. • The outdoor unit does not need vacuuming. DO NOT open the outdoor unit’s gas and liquid stop valves. • Ensure that the compound meter reads -0.1 MPa or below after 2 hours. If after 3 hours of operation the gauge reading is still above -0.1 MPa, check if there is a gas leak or water inside the pipe.
Note on Adding Refrigerant CAUTION • Refrigerant charging must be performed after wiring, vacuuming, and the leak test. DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so may damage or impact the unit’s function. • 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. • DO NOT mix refrigerant types.
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) The indoor and outdoor units are properly installed. b) Piping and wiring are properly connected. c) No obstacles are near the inlet and outlet of the unit that might cause poor performance or product malfunction. d) The refrigeration system does not leak. e) The drainage system is unimpeded and draining to a safe location.
Function of Automatic Wiring/Piping Correction 11 Automatic Wiring/Piping Correction Function The new product is able to automatically correct a wiring/piping error. Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED display shows "CE." This means the function is working. Approximately 5-10 minutes after the switch is pressed, "CE" will disappear, the wiring/piping error will be corrected, and the wiring/piping will be properly connected.

NOTE: For multi-split type air conditioners, one outdoor unit can be matched to different types of indoor units. All of the pictures in this manual are for demonstration purposes only. Your air conditioner may be slightly different, if similar in shape. The following pages introduce several kinds of indoor units that can be matched with the outdoor units. Unit Parts And Major Functions Operating Conditions Use the system under the following temperatures for safe and effective operation.
The air conditioner turns to FAN ONLY mode from COOL or HEAT (for cooling and heating models only) mode. Unit Parts And Major Functions When the indoor temperature reaches the set temperature setting, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode to the set point.
Manual Operations And Maintenance Operation mode selection Maintenance If you plan to leave the unit idle for a long time, perform the following tasks: 1. Clean the indoor unit and air filter. 2. Select FAN ONLY mode and let the indoor fan run for a time to dry the inside of the unit. 3. Disconnect the power supply and remove the battery from the remote control. 4. Check the components of the outdoor unit periodically. Contact a local dealer or a customer service centre if the unit requires servicing.
4 Troubleshooting CAUTIONS If one of the following conditions occurs, switch off the power supply immediately and contact your dealer for further assistance. Troubleshooting • • • • • The operation light continues to flash rapidly after the unit has been restarted. The remote control buttons do not work. The unit continually trips fuses or circuit breakers. A foreign object or water enters the air conditioner. Other abnormal situations.
Problem Possible Causes Dust is emitted from either the indoor or outdoor unit The unit emits a bad odor The fan of the outdoor unit does not operate The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity. The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
SYSTEMOPERATION COOLING OPERATION How it works: In cooling mode, your indoor evaporator will absorb heat from the room, then the outdoor condenser will discharge the heat to the outdoors. The sophia cooling capacity decreases as the outdoor temperature increases. This causes the ali ce to work harder and longer to hold the selected room temperature. Indoor Coil Freeze Protection: Frost may form on the indoor coil during cooling operations when the outdoor temperature below 50°F (10°C).
ENERGY SAVING TIPS 1. Relaxing room temperatureat night is OK: During the nighttime hours you don’t require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy. 2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat. In winter, the sun is your friend.
