Do not attempt to install the split air conditioner by yourself. 2. This air conditioner contains no user-serviceable parts.
Choosing the installation site Installation Warnings 1. Carefully read the installation manual before beginning. 2. Follow each step as shown. 3. Observe all local, state and national electric codes. This appliance must be installed by a qualified licensed HVAC technician in accordance with all applicable codes. All electrical connections should be performed by a licensed electrician. Failure to comply will result in a void of the manufacturer's warranty. 4. Pay attention to all safety notices.
Indoor Unit 1. Install unit where air flow will not be obstructed. 2. The installation location must support the weight of the indoor unit. 3. The site must be easily accessible for maintenance and replacement of the air filter. 4. The installation location must allow for the necessary space around the indoor unit, as shown in the figure 1.1. 5. There should be at least 3 feet (1 meter) between the unit and radio or television devices. It is ideal that the unit be installed at the center of the wall. 6.

Connective pipe and drainage installation 1. For the left-hand and right-hand piping, remove the pipe cover from the side panel. The pipe cover can be kept as it may be used when relocating the air conditioner to any other place. 2. For the rear-right-hand and rearleft-hand piping, install the piping as shown in figure 1.4. Bend the connective pipe to be laid at a height of 1-11/16" or less from the wall. Fix the end of the connective pipe.
3. Piping can easily be made by lifting the indoor unit with a cushioning material between the indoor unit and the wall. 4. Push the lower part of the indoor unit up on the wall, Then move the indoor unit from side to side, up and down to check if it is hooked securely. Cushioning material Piping and wrapping 1. Bundle the tubing, connecting cable, and drain hose with tape securely and evenly as shown in the sideward figure. 2.
Outdoor unit installation 1. Install the outdoor part of the unit on a flat surface to avoid excess noise and vibration. A condenser pad is recommended. 2. Direct the air vent toward an area without obstacles. 3. Install the unit at the site where it is exposed to as little wind as possible, especially in areas where it is frequently windy. 4. If the installation site is exposed to heavy winds, such as in coastal areas, place the unit along the widest part of the wall or use protective plates. 5.
Condensate drainage of outdoor unit (cooling only excluded) The condensate and defrosting water produced during heating in the outdoor unit can be properly discharged by drainage pipe. Installation method: Insert the drain connection into one of the holes of the chassis and then connect drainage pipe with drain nozzle. Insert drainage plugs (with different appearance) into the other holes.
Refrigerant piping connection Unit comes with 25' tubing bundle. It is not recommended to cut. If too long, loop for excess. Note: Keep original bend so not kinking of the tube occurs. Flaring work Main cause for refrigerant leakage is due to defect in the flaring work. Carry out correct flaring work using the following procedure: 1. Cut the pipes and the cable. A) Use the piping kit accessory or pipes purchased locally. B) Measure the distance between the indoor and the outdoor unit.
4. Flaring work. Firmly hold copper pipe in a die in the dimension shown in the table below. OUTER DIAMETER (inch) Bar Copper pipe Handle A (inch) Yoke Max.

Screw the flare nut with your fingers, and then tighten it with a spanner and torque wrench, as shown in figure 1.6. Indoor unit tubing Flare nut Pipings Figure 1.
Electrical work Electric safety regulations for the initial installation 1. If there is serious safety problem about the power supply, the technicians should refuse to install the air conditioner and explain to the client until the problem is solved. 2. Power voltage should meet the requirements in table 2.1. 3. Over current protection and circuit disconnect should meet the requirements in table 2.1 and the applicable local and national electrical codes. 4. Ensure the air conditioner is grounded well. 5.
Connect the cable to the indoor unit 1. The inside and outside connecting cable can be connected without removing the front grille. 2. Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed flexible type cord. 3. Lift the indoor unit panel up, remove the electrical box cover by loosening the screw. 4. Ensure the wire color of the outdoor terminal and indoor terminal correspond respectively. 5.
Connect the cable to the outdoor unit 1. Remove the electrical control board cover from the outdoor unit by loosening the screw. 2. Connect the connective cables to the terminals as identified with their respective matched numbers on the terminal block of indoor and outdoor units. The connective cable to power supply shall be approved polychloroprene sheathed flexible cord. 3. Secure the cable onto the control board with the cord clamp. 4.
Caution After the confirmation of the above conditions, prepare the wiring as follows: 1. Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2. The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation.
Purging the system with a vacuum pump 1. Check that each tube (both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage. 2. When relocating the unit to another place, perform evacuation using vacuum pump. 3.
5. Pipe length and refrigerant amount for multi split type air conditioner. (see tabel 2.3) Table 2.3 Cooling capacity (BTU/h) Max connective pipe total length (H1) Connective pipe length (Lx) Max height difference (H2) Air purging Additional amount of refrigerant to be charged 26000 25'~66' (x=1, 2, 3) 197' (H1=L1+L2+...+Lx, x≤3) 50' Use vacuum pump. R410a: 0.22ozs/ft (Pipe length-82') 34400 25'~82' (x=1, 2, 3, 4, 5) 246' (H1=L1+L2+...+Lx, x≤5) 50' Use vacuum pump. R410a: 0.
When using the vacuum pump For method of using a manifold valve, refer to its operation manual. 1. Completely tighten the flare nuts at connection point A, B, C and D. Connect valve core removal tool to the charging port, then connect vacuum hose to valve core tool. Open the schrader valve. Note: The schrader valve is inside the charging port. 2. Connect the other charge hose of manifold valve to the vacuum pump. 3. Fully open the Low Side handle of the manifold valve. 4.
Electrical safety Perform the electric safety check after completing installation: 1. Insulated resistance: The insulated resistance must be more than 2M. 2. Grounding work: After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. Make sure the grounding resistance is less than 4. 3.
Initial operation test Perform test operation after completing gas leak check at the flare nut connections and electrical safety check. 1. Connect the power, press the ON/OFF button on the remote controller to turn the unit on. 2. Use the MODE button to select COOL, HEAT (Only for models with heating function), AUTO and FAN to check if all the functions work well. 3.
