Environmental Checks
- Ensure there is no heat source or steam source near the installation area.
- Avoid obstructions around the inlet and outlet of both indoor and outdoor units.
- The area should be free from smoke or oil.
- Do not install in areas with flammable or explosive gas, or corrosive gas.
5.2. Indoor Unit Installation
Select Installation Location
- The wall for the indoor unit must be hard, flat, and firm to prevent vibration and noise.
- Maintain a minimum clearance of 15cm to the ceiling.
- Maintain a minimum clearance of 20cm to obstacles on either side.
- The unit should be installed between 230-260cm from the floor.
Fix Mounting Plate
Place the mounting plate on the wall and use a level to ensure it is horizontal. Select the position for at least 5 screws to firmly fix the plate.
Drill Wall Hole
After determining where the pipe will go through the wall, drill a wall hole. The wall hole should be inclined outward by 5-10 degrees, with a diameter of 60-80mm. Use an anti-dust bag to avoid dust when drilling.
Install Connection Cable
Pass the power cable out from the back of the indoor unit and fix it on the terminal board. Fix the cable with a clamp. Remove the knock-out panel with a knife and remove burrs to prevent the drain pipe from being broken.
Connection of Refrigerant Piping
Use both hands to turn the pipe in the desired direction. Aim at the pipe center, tighten the taper nut with fingers, then tighten with two wrenches. Use a torque wrench for precise tightening according to the pipe size (refer to the table in the installation video).
Install the Drain Hose
Connect the drain hose with the water outlet pipe, and fix it firmly with adhesive tape. The length should be more than 5cm to prevent water leakage.
Wrap the Piping
Wrap the refrigerant piping, wires, and drain pipe with wrapping tape.
Mount Indoor Unit
Put the refrigerant piping out of the wall hole. Put the indoor unit on the mounting plate. Push the lower part of the indoor unit until a 'click' sound is heard to ensure it is firmly fixed to the wall.
Pipe Protecting Ring and Putty
To protect piping and wires, a pipe protecting ring shall be installed and sealed with putty.
5.3. Outdoor Unit Installation
Select Installation Location
The outdoor unit must be installed in a firm and flat place to prevent vibration and noise.
- Maintain a minimum clearance of 20cm to the obstruction above.
- Maintain a minimum clearance of 30cm to obstacles on the left and right sides.
- Maintain a minimum clearance of 10cm for air intake on the right side.
- Maintain a minimum clearance of 200cm for air exhaust in front.
Install Outdoor Unit Bracket
If installing the air conditioner in a higher place, the operator should wear a safety belt and helmet. Use a level to ensure the bracket is horizontal and vertical. Use at least 6 expansion bolts to make sure brackets are fixed firmly on the wall.
Fix Outdoor Unit
Put the outdoor unit onto the brackets. Use 4 screws to fix the feet of the outdoor unit.
Connect Refrigerant Piping
Remove the nut from the stop valves. Aim at the pipe center of the stop valve, tighten the taper nut with fingers, then tighten with two wrenches. Screw the 2 caps back on. Use a torque wrench for precise tightening according to the pipe size (refer to the table in the installation video).
Vacuuming
Before vacuuming, check all the nuts of the indoor and outdoor unit are tightened. Connect the stop valve, charging hose, manifold valve, and vacuum pump as shown in the diagram (refer to the installation video). Turn on handle Lo to vacuumize. Vacuumize for at least 15 minutes, making sure the value on the pressure gauge is ≤0.1MPa. Keep pressure for 3-5 minutes after vacuumizing, ensuring pressure springback is ≤0.05MPa. Open the 1/4 liquid valve, and remove the charging hose.
Fix Cables
Remove the electrical box cover. Fix cables to the terminal board according to the wiring diagram on the E-parts cover. Must follow the wiring diagram inside the box cover. Use a clamp to fix cables. Put the electrical box cover back.
Refrigerant Adjustment
When the length of the connecting pipe is changed, an extra amount of refrigerant may need to be added or reduced to ensure optimal operation and performance.
| Length of connection pipe | Added or reduced refrigerant | Amount of refrigerant for the unit |
|---|---|---|
| <3m | CC≤12000Btu: reduce 20g/m | ≤1Kg |
| CC≥18000Btu: reduce 50g/m | ≤2Kg | |
| 3-5m | Not needed | - |
| 5-15m | CC≤12000Btu: add 20g/m | ≤1Kg |
| CC≥18000Btu: add 30g/m | ≤2Kg |
