Hanging on the wall outside of the outdoor unit, connected to the frame and the wall, outdoor air conditioning unit connected to the chassis used, should be closely connected to the need to ensure the quality and affordability. 6, the outdoor unit is installed on the roof terrace or balcony, use of reinforced concrete pouring two above the ground base platform 200 ~ 300mm Xuzhou hand air conditioning service, but also for steel made just bays around the outdoor unit or base all around must have gutters installed on the roof terrace in particular, we must pay attention to waterproof construction Xuzhou used central air conditioning recovery, to ensure that the roof does not leak, and can not be installed in the living room, above the bedroom. 7, should be added between the outdoor unit and at least 10mm thick base damping, should cushion into the bar. 8, the outdoor unit must be connected to the inlet and outlet fittings with a soft, and does not allow outdoor pipes inside the machine are subject to greater torque. 9, after the outdoor unit in place Xuzhou hand air conditioning compressor, to measure the level of the unit to ensure that the level of control within ± 1mm ??of. 10, into the water system, the lowest bit of saliva must install the drain valve, the outlet flow switch must be installed. Electric heating installed in the main inlet, the host inlet water filter must be installed. Hosts around the pipe can not bend too much. 11, before the connection to the host system must be pressure test for leaks. 12, the installation location of the host should be noted that the unit meets the pump head. 13, the water must be kept clean, in order to connect with the host import and export outlet line flushing two to three times. 14, pipeline leak detection system must be completed pressure, exhaust pipes and sewage drainage work, the end of the device can function properly with hot and cold load or no-load conditions. Air Conditioning Troubleshooting: First, the air-conditioning leakage 1, air conditioners live shell; 2, the power cord insulation damage and that it charged collide with the metal casing; 3, induction charging. Second, the air conditioning is not cooling (heating) 1, Freon (commonly known as refrigerant) enough; 2, power supply voltage is not enough; 3, the power is not enough so that the air conditioning is not cooling (heating); 4, ambient temperature is too high resulting in air conditioning is not cooling (hot); 5, long time without cleaning air conditioning maintenance; long brass 6, outdoor unit and indoor machines. Third, the air leakage 1, newly installed air conditioning extended drain leakage; 2, cleaning and maintenance caused by the prolonged absence of air leakage; 3, air conditioning lack of fluoride cause air leakage Xuzhou used central air conditioning recovery, used air-conditioning, refrigeration Shenger Da Xuzhou City Sheng Erda Refrigeration Electrical Services Limited. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) strong, credible, Xuzhou in Jiangsu Province of heat, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers.
