1. Installation and overhaul space: In order to consider the convenience and safety of installation, the space between the unit and the wall should be ensured as much as possible, because the maintenance of pipelines and lines is carried out on the front. In order to consider the convenience and safety of installation, the above space must be guaranteed.

2. After the installation position of the indoor unit is determined, drill a through-wall hole with the aperture size of 60-80mm and smooth drainage, and then place the through-wall sheath.

3. The indoor unit of split floor air conditioner is slender and easy to fall down. Therefore, the indoor unit must be firmly fixed during installation, and there is a position at the top of the indoor unit, which can be fixed on the wall with a fixed plate in random attachment; Remove the air intake grille at the bottom of the indoor unit and fix it on the ground with rivet bolts to prevent the air conditioner from falling over.

Installation of outdoor unit

1. Install the outdoor unit on the platform according to the selected installation position. If it is installed on a bracket on the wall, the mounting bracket shall be fixed with expansion bolts, and anti-loosening measures shall be taken. At least six φ 10 * 100 mm (specification) expansion bolts should be used for fixing the mounting bracket, and at least eight expansion bolts should be used for air conditioners over 4500W W. After fixing, the mounting bracket should be able to bear four times the weight of the machine and the installer.

2. Install a drainage elbow and a drainage hose at the bottom of the outdoor unit.

3. Place the outdoor unit on the mounting bracket, and fix it firmly with four anchor bolts with the diameter of 10 mm, which should be tightened from top to bottom to prevent the air conditioner and outdoor unit from falling from the air due to the falling of nuts.

4. If the outdoor unit is installed above the indoor unit, the height difference should be less than 20m.

5. Use a spirit level to check whether the outdoor unit is installed horizontally. When installing the outdoor unit, please ensure that the installation position is horizontal.

Connection of pipes and lines

1. One end of the connecting pipe of the split floor air conditioner is welded with a threaded pipe, which is easy to bend when installing the indoor unit and cannot be misused.

2. Bind the connecting cable with the connecting pipe and drainage hose, and determine the connection length and distance with the indoor unit. Use winding tape to wind evenly, and the winding direction should be from the outdoor unit to the indoor unit to prevent rainwater from entering the pipeline and affecting the temperature and insulation of the pipeline. At this time, attention should be paid to: the power line and the control line should not be intertwined, the connecting line should be placed on it, the drainage hose should be placed under it, and it should be arranged under the refrigerant pipeline; At the same time, do not bulge or bend the drainage hose, and do not pull the drainage hose for dressing.

3. Pass the wrapped pipes and connecting wires into the room through the hole in the wall to prevent damage to the bell mouth and sediment from entering the connecting pipes.

4. The cut-off valve of the outdoor unit should be completely closed. When connecting, unscrew the nut from the stop valve and connect the bell mouth immediately (within 5 minutes). Before taking over, use refrigerant to flush the air in the pipeline. When the connecting pipe is connected to the indoor unit, the maintenance reminder of Hefei central air conditioning is to connect the low-pressure pipe first and then the high-pressure pipe. When taking over, slowly unfold the high and low pressure pipes to avoid flattening and cracking. Then put the bell mouth of the connecting pipe and the joint on the same straight line, ensure that the centers of the two joint bodies are aligned, screw the connecting nut to the end by hand, and then tighten it with a torque wrench.

5. After the indoor unit is connected, it should be bent and shaped, and then connected to the outdoor unit. Be careful not to bend the hose back and forth more than 3 times, and the bending radius should be as large as possible (not less than 10cm).

6. When connecting with the outdoor unit, evenly apply refrigerating machine oil to the joint and bell mouth of the two-way valve, then align the bell mouth with the central shaft of the two-way valve, screw the connecting nut to the end by hand, and then tighten it with a torque wrench.

7. Disassemble the junction box of indoor and outdoor units, connect the power cord and signal cord as required, and screw down the bare wire after it is completely inserted.

8. After the above work is completed, the connecting pipe should be shaped and fixed as required, and it is best to fix it with a pipe clamp every 1.5m to prevent noise when the machine works.

9. After checking that there is no leakage point, wrap the joint between the indoor unit and the pipeline with a black insulating sleeve, and then bandage it evenly.
