It is something that professionals need to operate, then we still need to understand, the following small series of decoration home network will give you a detailed introduction to how to install air conditioning and precautions.
First, how to install air conditioning
1. After determining the position of the inner and outer machines, install the inner machine hanging plate immediately. After the external machine and the inner machine hanging plate are installed firmly, connect the connecting pipe straight and check whether the pipe is bent. Next, check the pipe. Whether there are cracks at the bell ends of both ends, if there is a crack, it should be re-flared, otherwise it will leak fluorine. Finally, check the control line for short circuit or open circuit. After confirming that the pipeline, control line and outlet pipe are good, tie them together and seal the connection nozzle. When crossing the wall, two people should slowly wear out inside and outside the wall to avoid strain; connect the pipe to the inside and outside, and connect the control line.
2. Exclude air from pipes and internal machines. The method is the same; (1) tighten the connected outer joint (fine), use a special wrench to loosen the valve stem of the shut-off valve for about 1 turn; (2) hear the outer joint (thick) click, 30 seconds Left and right, tighten the (coarse) joint with the hand; (3) loosen (rough) the valve stem of the valve on the tube; (4) completely loosen (fine) the valve stem of the cut-off valve on the tube. At this time, the emptying device ends.
3. Check the leak with detergent. Carefully observe whether there is any bubble in each joint. After verifying that the system does not leak, tighten the valve safety cap and start the test run.
Second, air conditioning indoor installation precautions
1. Choose a place that is strong, not susceptible to vibration, and is sufficient to withstand the weight of the unit;
2. Choose a place where drainage is easy and can be connected to the outdoor unit pipeline;
3. Choose a place that is not close to the heat source, steam source, and will not hinder the entry and exit of the unit;
4. Choose a place where cold or hot air can be sent to all corners of the room;

1. Connection details of indoor and outdoor copper pipes: How to connect indoor and outdoor copper pipes, firstly connect the copper pipeline connected to the indoor unit through the air conditioning hole to the outside of the wall. When piercing, carefully protect the copper pipe when it is bent. At the same time, do not remove the copper pipe plug to avoid dust falling through the wall. When connecting the outdoor unit, unscrew the copper pipe stop valve nut and the copper pipe flare. Align the center of the stop valve and turn the tube nut by hand until it cannot be rotated. Tighten with a wrench. Pay attention to the speed of the entire docking process as soon as possible, while avoiding debris entering the air conditioning system.
2. Connection between indoor and outdoor electromechanical lines Note: When the electric wire is extended indoors through the air-conditioning hole to the outside, do not let it press on the lower side of the hole to prevent the overload of the wire from causing fire caused by the wire; the wire is connected to the handle of the outdoor unit. After the parts are connected, cover the handle and press it tightly, and gently pull the wire to confirm that it has been pressed.
3, air conditioning drainage pipe end treatment details: Although the drainage pipe installation seems to be a negligible part, but in fact it is really very large. Properly connect the drain pipe to prevent the air conditioner from leaking, etc., and the resulting safety accident. Docking and dressing should be done when the drain pipe is connected to the indoor unit. The correct treatment of the drain pipe is to comply with the principle of “water flow to low flow†to prevent the occurrence of “climbing†of the waterway.
