The connecting pipe of outdoor air conditioner should be straightened slowly.
Seal the connecting pipe with the prepared four plugs.
Four ports prevent dust and moisture from entering the air. Plug it and use plastic.
In order to facilitate handling, these bags are tied in a circle.
In the air conditioning transfer, as long as it is required by the control operation specification, the refrigeration is good after the start-up operation, and no refrigerant is needed.
However, for micro-leakage in use or slow action during emptying in conveyor,
The refrigerant will be slightly reduced,
Or due to the tube shifting in the machine.
The air conditioner can not meet the normal operation after running for a period of time due to factors such as lengthening the air duct.

Question 3: How to Install Air Conditioner Correctly The installation steps of split air conditioner are as follows: Choose the installation location, first determine the installation location of indoor unit and outdoor unit, and where to connect the pipeline and drain pipe with cable.
Prepare the parts for installation and ensure that the parts in the original packaging are complete. Installation parts can be purchased in advance or prepared in advance with reference to the instruction manual.
When assembling and installing parts, the strength of the wall should be fully considered, and pins and anchor bolts should be selected and constructed.
Wall hole, according to the model and installation position of indoor unit, make a hole in the wall. The outdoor wall hole should be slightly downward 0.2-0.5cm to prevent external rainwater from invading the room along the pipeline.
Assemble the protective tube. In reinforced concrete walls, protective pipes must be used for pipes passing through metal clad walls, as shown in the following figure. Contact between steel bars in walls and metal plates and cable parts in pipes can lead to leakage. To prevent this, don't forget to assemble the protective tube.

Contact between steel bars in walls and metal plates and cable parts in pipes can lead to leakage. To prevent this, don't forget to assemble the protective tube.
When assembling the indoor unit, first shape the pipeline, extend the pipeline as shown in the figure below, and fix it with vinyl tape. The drain pipe should be lower than the refrigerant pipe.
As shown in the figure below, when pulling out the pipeline horizontally and hanging the indoor unit on the installation board, the following matters should be paid attention to.
Hang the outdoor unit on the hook of the installation board reliably, and it is best not to loosen it by hand.
The bending of the pipe through-wall hole is easy to cause damage, and the installer should pay full attention to it.
Assemble the outdoor unit and fix it in the place where it is placed (installation parts) or bricks. One of the specific matters is as follows:
Install it horizontally on a slightly higher platform so as not to be polluted by rain.
In an unstable place (roof), the outdoor unit should be bolted to the platform or brick, because the wind and rain vibration will cause the unit to fall.
If the site permits, the installation should be as large as possible.
When installing the outdoor unit, you should pay attention to the following matters.
Because the outdoor unit is heavier than the indoor unit, the strength of the parts should be allowed, especially the outdoor unit will be affected by the weather.
The outdoor unit is the most serious part of the air conditioner, and the installation method of minimizing noise and vibration should be adopted.
Direct sunlight will reduce the refrigeration efficiency, so a sunshade device should be installed.
Connecting tube bundle (cable drainage pipe for pipeline connection),
Question 4: How to install and debug the air conditioner? Air conditioning is very professional, and non-professionals should not install it at will.
During installation, the connecting pipe should be pressed tightly without any leakage.
Use F-22 (refrigerant) in the machine to remove air from the connecting pipe.
Connect the power cable correctly according to the connection diagram on the machine.
The drainage pipe should be high inside and low outside, and it should not be flattened to facilitate water discharge.
Debugging:
Check whether the operating current is normal, whether the suction and exhaust pressure is within the normal range, and whether the air inlet and outlet temperatures of the indoor unit are normal.
The above is the most basic installation procedure.
Question 5: How to install a new air conditioner Detailed steps How to install a new air conditioner Detailed steps
1. Ready
Survey survey installation site. The installation position of outdoor unit shall meet the following requirements
(1) The ground or wall should be able to withstand the natural vibration of the body.
(2) The installation site shall be convenient for operation, adjustment and maintenance.
(3) Noise, cold (hot) wind and condensed water during the operation of the external machine cannot affect the work, study and life of others.
(4) There should be no combustible gas leakage and explosives around the external machine.
(5) External machines should be installed in the backlight as far as possible.
The installation position of the indoor unit shall meet the following requirements:
(1) Avoid direct sunlight and keep away from heat sources.
(2) The air inlet and air outlet of the internal machine should not be blocked by obstacles.
Measure the distance between the internal and external machines. The distance between the internal and external machines should be less than 5 meters, and a new connecting copper tube should be prepared if it exceeds 5 meters.
Measure the position difference between internal and external machines. The distance between the internal and external machines should be less than 3 meters, otherwise it will reduce the refrigeration capacity of the air conditioner, increase the load of the compressor and cause overload protection.
fix
After determining the position of the internal and external machines according to the above principles, immediately install the internal machine hanging plate. After the external machine and the internal machine hanging plate are firmly installed, straighten the connecting pipe to see if there is any bending phenomenon. Next, check whether there are cracks in the bell mouths at both ends. If there are cracks, re-torch, otherwise it will leak fluorine. Finally, check whether the control line is short-circuited or open-circuited. After confirming that the pipeline, control line and outlet pipe are in good condition, tie them together and seal the connection nozzle. When walking through the wall, two people should cooperate inside and outside the wall, and wear it out slowly to avoid strain; Connect the pipes of internal and external machines, and connect the control lines.
Next, remove the air from the pipes and internal machines. The method is like this;
(1) Tighten the connected external machine joint (thin) and loosen the valve stem of the globe valve by about 1 turn with a special wrench.
(2) When the squeak of the external machine connector (coarse) is heard, tighten the connector (coarse) with a metal sheet hand for about 30 seconds.
(3) Loosen the check valve lever on the (thick) pipe.
(4) Completely loosen the valve stem of the stop valve on the (thin) pipe. This space-time fader is empty.
Finally, check the leakage with detergent, carefully observe whether there are bubbles coming out of each joint, and tighten the safety helmet of the valve after confirming that there is no leakage in the system, and then start the trial operation.
3. Run and debug
After the air conditioner is installed, an independent air conditioner power supply line should be set up. There are three copper cores Ф1.5-2 (mm) 2 in the power supply line of general household split air conditioner. The specification of the socket is 220V, 15A.
Check the voltage before powering on, and then start the operation with the remote control. After the outdoor unit works, check whether the running current is consistent with the nameplate. If the current is less than the nameplate, it can be regarded as less freon and there is no hurry to add fluorine. You can continue to observe the condensation or frost at the pipe joint.
The normal operation of any split air conditioner shall meet the following conditions:
(l) Low pressure is 4.9 kg/cm2 -5.4 kg/cm2.
(2) The connecting pipe can only be dewed, not frosted.
(3) Whether the running current is consistent with the nameplate.
(4) The air outlet temperature inside the machine meets the requirements.
That is, in summer (12- 16)℃; Winter (35-40)℃. Indoor temperature, 25-28℃ in summer and (18-23)℃ in winter.
Question 6: How do I put this back in the air conditioner? It seems that the net cover can only be put back if it is removed. You have to ask the air conditioner repairman.
Question 7: How high is the indoor air conditioner installed? It depends on what indoor unit it is! If that kind of concealment depends on the height of your room, it must of course be at least 20 cm from the top of your ceiling and about 20 cm from the bottom of your ceiling! If it is a wall hanging machine! I think as long as the height is appropriate, one is that you can't touch it at ordinary times, and the other is that at least children at home can't touch it! Third, with home improvement, it must be suitable for height! The above is my personal opinion.
Question 8: How to install the connecting pipe between outdoor unit and indoor unit of air conditioner? Two copper pipes are different, one is thick, the other is thin, the thick is connected with the thick, and the thin is connected with the thin.
Question 9: How to hang (hang up) the shelf of the air-conditioned indoor unit? 2 cm from the roof, are you kidding? Unless your roof is very low, generally about 2.2 meters above the ground, the installer depends on how high your roof is. It should be at least 20 cm away from the roof, because there is an air inlet on it that can be recycled, and the water outlet can be left out and right out and then out. It also depends on which wall you hang. The closer to the wall, the less copper pipes are exposed indoors, the more beautiful and the farther away. Ok, I don't want to type more. I hope I can help you. Please ask the installer again then. They will answer you one by one, because there will be a phone call after installation, and they will try their best to answer your questions.
Question 10: How to make a complete set of air conditioning installation data? I sent it to you. I am a civil engineering major, and now I am doing the data of ventilation and air conditioning engineering. Without the basic knowledge of this major, and the company has not filed the previous engineering data, I just don't know anything, and the project is completed.
