Indoor Unit Installation Before installing the indoor unit, you need to check the label on the product box and make sure that the model number of the indoor unit matches the model number of the outdoor unit. 1. Select an Installation Site Refer to the following diagram to ensure proper distance from walls and ceiling: Minimum 6 in (15 cm) Minimum 6 in (15 cm) Minimum 6 in (15 cm) ● If placed under 250cm, the cooling effect of the air conditioner cannot be fully utilized. Minimum 98.
2. Attach the Mounting Plate to the Wall The mounting plate is where you will mount the indoor unit. Φ55m Φ70mm Rear piping hole Bubble level Rear piping hole Φ55m Φ70mm ● Hold the mounting plate against the wall and adjust the plate using a bubble level until perfectly level. ● Mark screw holes on the wall and drill pilot holes with a drill. You may need a stud finder to find wooden studs to securely anchor the mounting plate.
● Using wire strippers, remove the rubber insulation from both ends of the signal cable in the lineet to reveal approx. 6 inches (15cm) of wiring. ● Using a crimp tool, crimp U-Type lugs (not included) on both ends of the wires. ● Feed the power connection wire from the rear right of the unit though the cable cross hole and pull it through from the front of the unit. hole power connection wire ● Match the colored wires to the correct labels on the terminal block.
4. Connecting the Refrigerant Pipings ● Align both ends of the refrigerant pipings and start to twist on the union nut by hand. ● Use a standard wrench on the pipe joint and an open-end torque wrench on the union nut to apply the proper torque as shown in the torque table below. NOTE: If the union nut is too loose it will cause leaks. Over-tightening may damage connections and cause leaks. Carefully tighten the union nut to the correct torque level referring to the Torque Table below.
Torque Table Pipe Diameter Nut Size Tightening Torque inch (mm) inch (mm) ft-lbs N-m 1/4 (6) 1/4 (17) 10 to 13 15 to 20 3/8 (9.5) 3/8 (22) 25 to 30 30 to 40 1/2 (12.7) 1/2 (25) 36 to 45 45 to 55 5/8 (16) 5/8 (29) 50 to 60 60 to 65 ● Connect the drain hose to the outlet pipe of the indoor unit and secure the joint with tape. drain hose outlet pipe outlet pipe drain hose tape ● Wrap the joints with the included insulating material to prevent condensation.
● Wrap the refrigerant pipes, electrical cables, and drain hose with tape so it looks like the below figure electrical cables indoor unit refrigerant pipes tape drain hose ● Reserve a few inches of drain hose and power cable. When wrapping to a certain length, separate the indoor power cord and then separate the drain hose. drain hose connection pipe Tape indoor power cord Note: When wrapping the bundle, keep the ends of the piping unwrapped.
5. Drilling the piping hole on the wall You must drill a hole in the wall for the wrapped bundle of pipes to connect the indoor and outdoor units. ● Choose an appropriate location for the piping hole based on the position of the mounting plate and the direction of the pipe. There are four directions you could choose: 1. Out of the right side of the indoor unit 2. Out of the rear right side of the indoor unit 3. Out of the rear left side of the indoor unit 4.
● If you choose a pipe direction out of the left or right side of the indoor unit, you will need to knock out the corresponding hole on the bottom of the side panel. Left Right Knock-out Panel ● Drill a hole with a 2.2/2.8 inch (55/70 mm) diameter through the wall where you want the pipe to go through. To ensure better drainage, slope the hole at a slight 5-10 degree angle downwards. The hole should be drilled lower than the mounting plate, as shown in the example figure below.
indoor upper hook outdoor sealing gum bundle of pipes lower hook of wall-mounting frame 7. Extend the pipe by unwinding it ● Extending the pipes should be clung to the wall, bent slowly. The minimum radius of bending the pipe should not exceed 4 in (10 cm). ● If the pipe is repeatedly bent or extended, it will become hard and difficult to manipulate. Avoid bending or extending the pipe for more than 3 times.
Outdoor Unit Installation 1. Select a Installation Site Refer to the following diagram to ensure proper space around the unit: minimum 19.7in (50 cm) minimum 11.8 in (30 cm) minimum 11.8 in (30 cm) minimum 19.7in (50 cm) minimum 78.7in (200 cm) Appropriate install locations should follow these standards: ● Open ventilation space around the air conditioner to ensure airflow. ● Location must be convenient to install and not disturb others. ● Protected from prolonged periods of direct sunlight exposure.
Note: If the unit is frequently exposed to heavy rain or snow. Build a shelter above the unit to protect it. Be careful not to obstruct airflow around the unit. 2. Install the Drain Joint Heat pump units require a drain joint if the unit is elevated off the ground. Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. ● Connect the outdoor drain joint into the hole in the base pan of the unit, as shown in the picture below.
4. Connect the Refrigerant Pipe to Outdoor Unit ● Remove the screw cap of the valve and aim the pipe joint at the bellmouth of pipe. refrigerant pipes pipe joint liquid valve union nut gas valve ● Align both ends of the refrigerant piping and start to twist on the union nut by hand. ● Use a standard wrench on the pipe joint and an open-end torque wrench on the union nut to apply the proper torque as shown in the torque table below. Note: Over tightening may damage connections.
Note On Pipe Length The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 16.5ft (5 meters). Refer to the table below for specifications on the maximum length. Capacity (BTU/h) Min. Length (ft/m) Max.
b. Remove burrs Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed. ● Hold the pipe at a downward angle to prevent burrs from falling into the pipe. ● Using a reamer or deburring tool, remove all burrs from the cut section of the pipe. pipe shaper downwards c. Flare pipe ends ● After removing burrs from the cut pipe, seal the ends with tape to prevent foreign materials from entering the pipe. ● Sheath the pipe with insulating material.
The end of the pipe(“A”) must extend beyond the edge of the flare form in accordance with the dimensions shown in the table below. A(mm) Outer diameter (mm) Max Min Φ6 - 6.35(1/4") 1.3 0.7 Φ9 - 9.52(3/8") 1.6 1.0 Φ12-12.7(1/2") 1.8 1.0 Φ15.8-16(5/8") 2.4 2.2 ● Remove the flaring tool and flare form, then inspect the end of the pipe for cracks and even flaring. If there is any blemish, do it again according to the steps above.
5. Connect the Signal and Power Cables ● Remove the wire cover on the outdoor unit. All wiring must be performed in accordance with the wiring diagrams shown below. ● Match the wire colors with the labels on the terminal block and firmly screw the U-Lug of each wire to its corresponding terminal on the terminal block. ● After checking to make sure every connection is secure, loop wires around the terminals to secure the connection. ● Use a cable clamp to fasten the cable to the unit.

Air Evacuation Preparations and Precautions Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system. Evacuation should be performed upon initial installation or when the unit is relocated.
● Close the vacuum pump and wait for 5 minutes to ensure there has been no change in system pressure. If the pressure decreases there may be leakage, please refer to the Gas Leak Check section. ● Remove the manifold gauge, open the valve core of the liquid valve and gas valve completely by turning anticlockwise with a hexagonal allen wrench. ● Tighten the screw caps of the valves and refrigerant charging vent once complete. Gas Leak Checks There are two different methods to check for gaseous leaks. 1.
2. Check for Electrical Leakage During the Test Run, use an electroprobe and multimeter to perform a comprehensive electrical leakage test. If electrical leakage is detected, turn off the unit immediately and call a licensed electrician to find and resolve the cause of the leakage. Note: This may not be required for some locations in the US. Note: All wiring must comply with local and national electrical codes and must be installed by a licensed electrician.
