>>>Recommendations: Easy Method Makes You a Master in Door and Window Acceptance
1. The thickness and heat preservation performance of the insulation material are very important. Some installation teams will just cover the outer layer of the pipe, or use a thin insulation cotton. This will not achieve the insulation effect, but will cause condensation on the surface of the insulation material. phenomenon.
2. The normative installation team should not leave the design drawing, so that the machine can be properly installed in accordance with the requirements of the owner and the factory during the installation process. In addition, it will also form an effective communication with the decoration team and confirm that the installation will not conflict with the actual situation of the current decoration.
3. After fixing the position, fix the indoor machine with a full-threaded suspension rod to the ceiling to ensure the installation procedure of the next indoor unit.
4, the indoor machine to ensure horizontal installation, or in the future will greatly increase the noise during use, will also reduce the service life of air conditioning. In addition, special care should be taken in the lifting to avoid clinging to the ceiling, which can cause resonance and increase noise.
5. The double nut must be fixed at the lower end of the screw to ensure the stability of the indoor unit. For example, the use of a nut can cause loosening and noise during the operation of the indoor unit.
6. After the lifting is completed, the indoor unit must be wrapped with cardboard or plastic film to prevent the dust and odor from entering the machine during the subsequent decoration, resulting in a large amount of dust and odor blowing on the first use to affect the health of the family. In addition, the accumulation of dust can also affect the operating efficiency of the air conditioner.
7. Before the pipe is fixed, it is necessary to measure the size. Every 1.2M~1.5M copper pipe needs to set a support, and the drain pipe is 0.8M~1M.
8. The fixing of the fastener is similar to the fixing of the prior suspension rod, which is mainly to avoid vibration, sagging off and affecting the effect of the air conditioning during the operation. In addition, it should be noted that the clamp cannot be buckled too tightly, otherwise it will damage the insulation material.
9. Special attention should be paid to the drainage pipe to maintain a slope of at least 1/100, otherwise it will lead to poor drainage and condensate cannot be discharged in time.
10, brass is an essential material for air-conditioning installation, the regular installation company is using a large plant to provide phosphorus-free deoxidized copper pipe, have a test report, the wall thickness to 0.8mm ~ 1mm. However, due to the sharp rise in prices of copper pipes last year, the price rose from 30 yuan/kg to 40 yuan/kg today. Therefore, some informal installation companies use this point to buy copper pipes that have been reprocessed from scrap copper. This causes the refrigerant Freon to leak into the impurities.
11, drains to use PVC material row / water supply pipe, some informal installation team will cut corners with PVC material line tube, and some even simply replaced with counterfeit, so easy to cause leakage due to embrittlement.
12. The selected signal line and power supply line must be products of regular manufacturers. The signal line should be configured according to different machines. It should be a double-core shielded line so that it will not be unfavorable and interfered with by Other lines.
13. The thickness and thermal insulation performance of insulation materials are very important. Some installation teams will just cover the outer layer of the pipe, or use a thin insulation cotton. This will not achieve the insulation effect, but will cause condensation on the surface of the insulation material. phenomenon.
14. When fixing the pipe, the regular installation team will use materials such as clamps, expansion screws, and full-threaded hangers on the material. The non-regular installation team will use iron wire and wires to easily tie it. This will result in Insulation is degraded by over-pressing.
