For central air conditioning installed in the family, for the time being there is no special specification central air conditioning installation, in order to facilitate supervision and inspection of home users, so that consumers peace of mind at ease to use, the Harbour through the small series put together following installation specifications. Of course, these specifications are referring to large commercial central air conditioning installation specifications from: 1, residential central air conditioner indoor unit is generally installed in the ceiling, in determining the installation location, should be noted: (1) the installation position of the indoor unit not near a power (such as electric heaters, gas stoves, etc.) and steam sources. (2) blowing cold air should flow extraordinary activities of the main plant, there are no obstructions near the exhaust vents. (3) from the host computer to a TV, stereo and other one meter above the central air-conditioning manufacturers, in order to avoid mutual interference. Around (4) anti-set air intake Do not obstruct the air intake of obstructions. (5) away from heat, flammable gases place. (6) and the upper ends should leave room. (7) Do not go near the place of high-frequency equipment, high-power wireless devices to avoid interference with the normal operation of air conditioning. The basic method of central air-conditioning maintenance of: 1, regular cleaning the air filter. Cleaning time usually 2-3 weeks. The steps are: Remove the panel; extract air filter; clean air filter. The air filter on the central air conditioning rinse under the tap, as the filter with plastic frame and polyester filament repression, so we can not use more than 40 ℃ hot water, to prevent shrinkage. After cleaning the filter net of the water can be drying, insert panels, installed air conditioning. 2, the protection of the condenser and evaporator fins. The condenser and evaporator fins is 0.15 mm after aluminum expander set into the brass made, it can not withstand a collision, if damaged fins (rewind), will affect the cooling effect of air conditioning, refrigeration reduced efficiency. Therefore, pay special attention to protecting. 3, protect the cooling system. If damaged parts or connecting pipe cooling system, it will cause a refrigerant leak, the air conditioner will not be cooling. 4, the correct selection of fuse (fuse). By product specification indicated nominal current fuse specifications, excessive role of the central air conditioning can not afford the insurance Which is good, too small often blown. 5, the air conditioning manual stop, open operating time, should every 2 minutes, can not continuously stop, start.
