浅谈空调安装时需要注意的几点事项

1、 安装位置的选定：
安装位置的选择要求
选择坚固不易受到震动，且足以承受机组重量的地方。
机组应远离各类电器、热源2米以上的地方。
儿童不易触及的地方。
应尽量使室内、外机保持最近，连接管尽量的短。
室内、外机的排水不得影响到下面住户及用户自身的建筑物。
避免易污染（易燃易腐蚀气体）的位置。
室内机下方应尽可能避开电视机、音响、电脑等高级家用电器。
室内机应选择可将冷、热风均匀送到室内各个角落的地方。
室内、外机周围应保留足够空间，以利空气流动。
室外机应装在不影响左邻右舍的地方。
室外机选择不易受到雨淋或阳光直接照射及通风良好的地方。
保证空调维护、检修方便的地方。
保证空调室外机出风口避开逆风向位置。
安装位置的确定
按照以上要求选定室内、外机的具体安装位置（必要时做好相关标识）
当用户要求的安装位置不合理或对机器的后期使用有重大危害时，应予以指出并和用户进行耐心的解释，说明正确的观点并加以修正
1、 Selection of Installation Position (Indoor / outdoor lens sequence needs adjustment)
Subtitle
Commentary
Requirements for Installation Position
The installation shall be operated at the place which is solid, unlikely subject to shock and able to bear the weight of machine.
The outdoor unit shall be installed at the place which with good ventilation, and unlikely subject to rain or direct sunshine. Ensuring that the air conditioner can be easily accessed for maintenance and repair.
Keep the indoor and outdoor units as close as possible. The connection pipe shall be short as it might be.
To facilitate the air flow, keep adequate space around the indoor and outdoor unit, and avoid flammable or corrosive gas nearby. The drainage shall not affect the constructions of dwellers underneath or the user himself.
The machine shall be kept 2m or more away from the electric appliances and heat source.
Avoid TV set, sound box, computer and other deluxe home appliances below the indoor unit.
To facilitate good ventilation, avoid the air out of the outdoor unit is in the upwind position.
The indoor unit shall be able to blow the cold and hot air evenly to everywhere of the room.
According to the power supply mode (powered by indoor or outdoor unit) and the length of power cable, select the position which close to the power supply, in order to facilitate the connection of power line. Moreover, ensuring that it is not needed to extend the power cable and selecting a position beyond reach of children.
Determination of Installation Position
Select the final position of indoor and outdoor unit according to the requirements above (Mark properly if needed).

If the user’s chosen position is unreasonable or harmful to the daily usage of the units, please correct his idea with patient persuasion.

2、 室内机弯管：
根据挂墙板的位置选择穿墙孔的位置(走管方式的选择:1、直接往机身左侧走管；2、直接往背面走管，弯管的时候请用右手托住直角处，然后左手往上面轻轻旋转，旋转至90度后停止；、3、往右边走管，此步骤与上一步骤要求相同，只是弯管的角度比上一步骤大，应该弯到180度为止，注意在弯这个角度的时候力量要轻、动作要慢，否则很容易把管弄瘪)，然后打一个孔（比穿墙套管外直径稍大，确保穿墙套管可以顺利穿过）。注意：为有利于内机排水，室内机须略高于穿墙孔，同时保证穿墙孔向外向下倾斜。
2、Select the position of wall-cross hole according to the position of wall-mounting plate.
Selection of piping mode: Try not to choose the mode of right exit-pipe so as to ensure the orderliness and smoothness of the pipe.
1. Route the pipe directly along the right side of the machine body.
2. Route the pipe directly on the rear. When bending the pipe, please support the elbow with your right hand and then use your left hand to rotate slightly for 90° before stop.
3. Route the pipe along the left side. This step is the same as the above step. The only difference is that the bending angle is higher than that in the previous step, that is, it should be bent to 180°. Take care to rotate this angle slightly and slowly; Otherwise the pipe would be flattened easily . Then, drill a hole (shuld be a little larger than the outer diameter of the wall-cross tube so as to ensure the wall-cross rube can be inserted through).
Caution: For easy drainage of the water out of the internal unit, the indoor unit shall be mounted slightly higher than the wall-cross hole. Meanwhile, the wall-cross hole must be inclined outward down.

3、收冷媒：在制冷模式下，先关掉高压阀，待系统运行1分钟左右，室外机吹冷风的时候，再关掉低压阀。系统收冷媒完毕。
3. Collect the refrigerant: set the unit in the cooling mode, and switch off the high pressure valve. After about 1 minute running of the system and the outdoor unit blows the cool wind, shut down the low pressure valve. Then the collecting refrigerant is done.

4、系统排空：当空调系统安装好后，用十字螺丝刀顶住维修阀顶针，然后打开高压阀，待维修阀处有冷媒喷出后，放开维修阀，最后打开低压阀。系统排空完毕。
4. Vacuate the system: after the installation of the unit, use the screwdriver to hold the eject pin, and then open the high pressure valve. After the service valve leaks refrigerant, loose the service valve, and open the low pressure valve，then the vacuation is done.

5、 加长管后系统需要增加的冷媒量：
5、After lengthening the indoor and outdoor connecting pipe，the AC system should charge additional refrigerant amount。Refer to the following form。
Additional refrigerant amount
Liquid pipe diameter φ6.35mm (1/4〞)
Liquid pipe diameter φ9.52mm (3/8〞)
(piping length-5)m×30g
Or (piping length-16)ft×0.3oz
(piping length-5)m×65g
Or (piping length-16)ft×0.7oz
1m=3.28ft;
1ft=0.3048m;
1oz=28.34752g;

7、用户电源的检查（电表容量、线径、漏电保护开关、地线、电压）

电源检查
用万用表测量电源电压，需在额定电压正负10%的范围内。
空调电源应用专用分支线路，并保证整条供电线路（分支线路、电源线、电表、空气开关等）的容量大于空调最大额定电流。
电源配置及布线符合当地电气安全要求
建议用户为空调配专用空气开关与漏电保护器等保护装置，容量应满足空调需要，有保险丝保护线路严禁使用铜丝代替保险丝。

7、Check the user’s power supply (kilowatt-meter capacity, wire diameter, electric leakage protection switch, ground wire and voltage)

Subtitle
Commentary
Check the power supply
Use the multimeter to measure the power voltage, which shall be within +/-10% of the rated voltage.
Use special line for the power supply of air conditioners, and ensuring that the capacity of entire supply line (branch line, power line, kilowatt-meter, air switch, etc) is higher than the maximum rated current of air conditioner.
The power configuration and cable distribution must meet the local requirements for electrical safety.
Advise the user to apply special air switch, electric leakage protector and other necessary protection devices for air conditioners. Their capacity shall meet the needs of air conditioner. For the line with fuse, it is prohibited to use copper wire to replace the fuse.
