First, the entrance survey
1, survey the structure of the house, according to the owner's decoration requirements to confirm the indoor and outdoor machine location, all kinds of pipes and lines.
2, professional design
2.1, professional and technical personnel according to the survey results for load calculation, model selection and drawing to ensure the load of air conditioning, to provide a basis for construction.
2.2, customer confirmation of the design and drawings.
3, move into the job
3.1, when moving in, must be lightly put, to ensure that the fuselage and contents are not damaged.
3.2, in accordance with the direction of the standard arrow to place air conditioning, to ensure that the drainage pump is not damaged.
3.3, according to the standard stacking, to ensure that the air conditioning will not be crushed.
Second, the main material selection and installation
1, refrigerant distribution tube
1.1, should choose a good material of copper pipe, and wall thickness to meet the prescribed standards, can not use not to achieve the specified thickness of copper pipe. This may result in a refrigerant leak.
1.2. Both ends of the copper pipe must be covered with a plastic cover to prevent moisture and impurities into the copper pipe.
2, the difference tube
2.1, the use of high-quality difference tube, to ensure that the refrigerant correct diversion, so that the operation of normal. If the use of poor quality of the difference tube, may be due to poor welding of the difference soldering caused leakage.
2.2, with professional one-size-a-body insulation materials, can avoid the addition of insulation materials when the emergence of gaps, thereby preventing condensation and cause dingliing water.
3, drainage pipe
3.1, if not in accordance with the size of the indoor machine water pipe selection condensing pipe, the pipe diameter can be fine, will lead to poor drainage of condensate.
3.2, the selection of PVC material row \/ water distribution pipe, such as the selection of non-PVC material pipeline, it is easy to brittle lead to leakage.
3.3, horizontal pipe diameter and allow condensate discharge relationship.
Third, the selection and installation of auxiliary materials
1, insulation materials
1.1, such as the use of thin insulation cotton shoddy products will not achieve the insulation effect, resulting in insulation material surface condensation.
1.2, the duct if not added insulation material, will cause the surface of the duct dew, resulting in unnecessary energy consumption.
1.3, the thickness of insulation material should be determined by the size of the tube.
2, remote control wiring (signal line), indoor and outdoor machine power cord
2.1, according to the wiring size provisions to choose the signal line, otherwise it is easy to cause poor signal.
2.2, should be based on the equipment's operating current to select the appropriate cross-section of the power cord, such as the wire diameter is too thin will cause the power cord overheating caused the source line to burn out.
2.3, signal line should be selected dual core shielding wire (for the Go CCC certified products).
3, lifting materials
3.1, the installation of hooks when the material with clamps, expansion screws, PVC pipe hoops, 10mm full-threaded boom and other development materials.
3.2, such as the use of wire, wire and other medium-packed pipes, will lead to excessive compression of insulation materials so that the insulation performance of the decline, resulting in the phenomenon of condensation.
4, duct material
4.1, the installation of hooks when the material with clamps, expansion screws, PVC pipe hoops, 10mm full-threaded boom and other development materials.
4.2, such as the use of wire, wire and other medium-packed pipes, will lead to excessive compression of insulation materials so that the insulation performance of the decline, resulting in the phenomenon of condensation.
