1, the compressor should be installed at an angle of inclination should not be greater than 5 degrees; compressor nameplate label consistent lubricating oil, to ensure that the power supply and compressor nameplate parameters are consistent with the compressor, the compressor is filled with dry nitrogen inside the factory, in the takeover of the compressor before the release of the pressure inside the compressor.
2, the refrigeration system leak detection and compressor work, the maximum pressure can not exceed the pressure specified on the compressor nameplate. Do not use air to test run the compressor, because high pressure air mixed with oil, mixed high-pressure gas may be due to the high temperature of the scroll exhaust port explosion, resulting in damage to the compressor!
Check that the suction and discharge valves are open before starting the compressor. It is very important that the discharge valves are fully open before starting the compressor. If the discharge valves are not fully open, dangerous high pressures and high temperatures will be generated in the compressor. 4. The maximum system disconnection pressure should not exceed 28 bar. It is recommended that the high pressure disconnection should be manually reset in order to completely eliminate the problem. bar.
5. Do not mix vinegar oil, mineral oil or alkyl benzene. Compressor factory has been filled with lubricating oil, R404A compressor is used POE synthetic cool oil, R22 compressor is used 3GS mineral oil compressor nameplate marked the initial amount of oil before the factory, the site can be filled than the initial amount of less than the initial amount of 100ml or so.
6, pipeline welding, the pipeline must be filled with nitrogen to protect the internal, to prevent the generation of oxidised skin clogging system, welding any copper-silver alloy welding consumables can be used, preferably containing 45% of the silver electrode, to obtain the best welding quality. It is recommended that when welding suction and discharge pipes, wrap them with a wet cloth before welding.
7、When the compressor is running but can not establish differential pressure or the running sound is too loud. May be the compressor U, V, W three-phase wiring error, you need to adjust two of the wire.
