c. 连接环节 Connection steps
(1) 工具准备 Preparing tools

一切工具、备件、材料必要准备齐全，如冲击钻、真空泵、氮气瓶、配管工具、制冷剂压力表等。
All tools，reserve parts and materials must be prepared all in readiness，for example：Percussion drill，vacuum pump，nitrogen cylinder， pipe-fit tools，refrigerant gauge and so on．
(2) 室内机安装 Indoor unit installation
参照前述规定安装固定室内机。
Install and fix indoor unit according to above demands．

(3) 室外机安装 Outdoor unit installation
参照前述规定安装固定室外机。
Install and fix outdoor unit according to above demands．

(4) 打墙孔 Drill holes in wall
在墙底部打圆孔或长方形孔，以穿过连接管、排水管、电线等。
Drilling round or square holes in the bottom wall to let connecting pipe，water drain pipe and wires cross．

(5) 管路连接 Connecting pipes
申菱牌风冷系列空调机管路连接方式有两种：不大于或等于LF/LFD29N以及LF/LFD58N、LF/LFD85N机组采用喇叭口连接，其他类型机组采用焊接方式连接。连接时须注意如下几点：
There are two methods to connect pipes of “SHENLING”air-cooled series air conditioner：Flared-tube connection is for units smaller than LF/LFD29N and LF/LFD58N/ LF/LFD85N. And welding connection is for the other units. The following points must be paid attention to while connecting;
喇叭口连接方式
Way of flared-tube connection
(a) 盘管展开时采用反绕办法缓慢进行，避免折扁铜管。
Unfold coiled pipe slowly by way of twisting in reverse，so as not to bend the copper tube flatted.
(b) 管道弯曲加工用弯管器进行，弯曲半径较大时也可用手缓慢地弯曲。弯曲半径过小，容易导致管子损坏，弯曲半径限度规定不不大于铜管外径6倍。
Use tube bender to bend machinery pipe or bend by hand when the radius of curvature is larger．If the radius of curvature is too little，pipes may be miner than 6 times of the pipes external diameter.

(c) 松开角阀连接处螺母，卸下连接管堵头，在喇叭处涂上冷冻油，迅速地将两者连接起来（规定5分钟内），喇叭口位置对好之后，再用板手紧固螺母。
Loosen nut and remove the plug from eagle valve，then smear the flared with refrigerant oil and connect the two parts together quickly (in 5 minutes)，when the flare’s seat well，then tighten the nut using spanner.
(d) 当所需要管长超过5m时，需按规定加长铜管并补充制冷剂
If connecting pipe is longer than 5m，increase the length of the copper pipe and add refrigerant.
焊接方式：　Way of welding connection
(a) 采用硬钎焊连接所有接头。
Connect all joints by braze welding.
(b) 铜管切割后须清除毛刺及管内异物。
Get rid of the bur and foreign matter in pipe after cutting the copper tube.
(c) 焊接时管内必要充氮。
Fill tube with nitrogen when welding.

(6) 充氮试漏 　Charge with nitrogen to have leakage test
铜管连接之后，从接头处制冷剂充注口（喇叭口连接式在角阀上，焊接式须打开所有室内侧球阀，再从室内机制冷剂充注口充氮）充入氮气至1.5Mpa，用肥皂液检查连接管各接头处与否有漏，若有漏，接头必要重新解决。
注意：切勿用氧气或乙炔气试漏！
After connecting copper pipe，charge with nitrogen to the pressure of 1.5MP through charging valve at the joint (the charge valve of flared connecting type is at the eagle valve，but as to welding connecting type，all indoor side ball valve must be opened，then charge nitrogen through the charge valve of indoor unit). And using soapsuds to check every joint of the connection pipe to see if there is any leakage or not，if it is，the joint must be dealt with again ．
CAUTIONS：Be sure not to do leakage test with oxygen or acetylene.

(7) 空气排除 Air discharge
充氮试漏之后，必要排除管道内空气。因系统空间较大，建议采用真空泵抽除管道内空气，不要采用放制冷剂办法来排除管道内空气。否则由于排除不凝性气体不彻底会导致系统高压升高和制冷性能下降。
Air in pipes must be removed after leakage test. As the system space is a little large，vacuum pump is suggested to draw air from the pipe，not to get rid of the air by charging pipe with refrigerant，or because incondensable gas can not be exhausted，the high pressure of system will rise and refrigerant rating performance descend.
(8) 真空检漏 Vacuum leakage test
抽真空至管内绝对压力1300Pa，保持5分钟压力无变化，否则接头处有漏须重新解决。抽真空时，喇叭口连接式只需抽除管道内空气，焊接式必要启动室内侧所有球阀后(因室内机充有少量氮气,因此必要连同室内机一起抽,但室外机球阀不能开)，再在空调机制冷系统高低压两端制冷剂充注口分别抽除空气，不能只抽一端。
Achieve the vacuum in pipe (absolute pressure 1300Pa) and keep it for 5 minutes without pressure changing，and if it changed，there must be a leakage in joints，so the joints must be dealt with again. Only the air in pipe need to be vacuumed for flared connecting type unit. But for welding connecting type unit all indoor side ball valves must be opened (because indoor unit has been charged with a little nitrogen，pipe must be vacuumed with indoor unit together，but ball valves of outdoor side can not be opened)，the draw air separately from the charging valve of the refrigeration system in air conditioner，when vacuuming ，pay attention not to vacuum one side only.

(9) 放出制冷剂 Let refrigerant out
空调机出厂时制冷剂贮存在室外机内。放出制冷剂时应先打开制冷剂液路两个角阀 (或球阀)，再打开另两个角阀(或球阀)。启动角阀时须注意，必要拧开至上死点并略拧紧，再盖上防漏盖帽。球阀只需将阀杆转90°,(阀杆上有箭头批示流动方向)再盖上防漏盖帽。所有阀都打开之后，须将原“全关”挂牌换为“全开”挂牌。
Refrigerant is stored in outdoor unit when air conditioner leaving factory．Open eagle valve ( or ball valve)，which is thinner pipe’s valve，in refrigerant liquid pipe of every system first when letting refrigerant out，then open other two eagle or ball valve． While opening eagle valve，the valve rod must be opened to the top dead center and tighten a little，then leak proof cup must be fitted. For ball valve，turn the rod to the eagle of 90°(there is arrow indicating turning direction) and fit the leak proof cap．After all valve opened，change the hanging plate “Close all”to“Open all”
(10) 复查接口泄漏 Check again the joints leakage
阀门启动之后，用卤素检漏仪或肥皂液在接口处复查有无泄漏。
After valves opened，use halide leak detector or soapsuds to check the joints．
(11) 电线连接 Connecting electrical wires
用多芯电缆线连接室内外机接线端子。
Use multiple core cable with every conductor’s section being to connect indoor and outdoor terminals．
注意：每台室外机必要按序号和相相应制冷系统电路某些进行连接，切勿接错，否则空调机不能正常运营。
Note：Each outdoor unit must connect with electrical branching of corresponding refrigeration system according to the number，if in disorder，the air conditioner cannot operate normally．

(12) 包扎 Wrapping up
连接铜管包好保温层之后 (仅对焊接方式而言，喇叭口方式铜管上已套好保温管)，将铜管、电线等用塑胶带妥善包扎并固定好。
After connection copper pipe binding up the thermal insulation (only for welding way connection for flared tube connection，the pipe has been cased with insulation layer)． Then bind up pipes，wires，etc. with plastic tape and tighten them．
4. 制冷剂补充 Supplementing refrigerant
当连接管路超过5m时，必要补充制冷剂(R22)，请顾客安装时参照下表进行补充。停机时补充制冷剂可从角阀冷剂充注口充入，开机时补充制冷必要从压缩机吸气口(即低压端，压缩机较粗接管) 冷剂充注口吸入,此时冷剂罐不适当倒置，以保证制冷剂以气体方式吸入压缩机，避免压缩机发生液击而受到损坏。
When connecting pipe is in excess of 5m，refrigerant (R22) must be supplemented while user installing．Please refer to following table. When unit is not working，refrigerant can be charged from charge plug at angle valve，if the air conditioner is operating，refrigerant must be charged from the plug of compressor’s drawing side　(lower pressure side，thicker connecting pipe of compressor),　at this moment the refrigerant can be drawn into compressor as gas，for preventing the compressor from damaging because of liquid shocking．

注意事项：Attention
排水管走管位置始终不能高过达室内机排水孔位置，同步室内机另一侧排水孔必要 用丝堵堵死。冷凝水排至下水道路中需加设U形弯(见图)以防臭气吸入空调机内。

The drain pipe cannot be higher than the water outlet hole of indoor unit，and the other side’s drain water hole must be blocked with screw stopper. If condensed water is to be drain
