By keeping the compressor clean and undamaged, checking the electrical system and other components, controlling the ambient temperature, and training the operating personnel, the scroll Copeland compressor can be more efficient and last longer.

Maintenance tips

• Clean and undamaged: Keep the outside and inside of the compressor clean. They should be no foreign bodies or dust inside the compressor to avoid blockages and damage. The outside of the compressor should be cleaned regularly to prevent dirt from covering the heat dissipation holes and damaging heat dissipation.
• Check the electrical system and other components: Regularly check the technical manuals and forms of Copeland scroll compressors to ensure that the compressor is correctly wired and the power supply voltage is within the specified range. Besides, on a regular basis, users should also check the contactor, thermal relay, and other parts of the electrical system to ensure that they are not excessively worn, corroded, or loose.
• Control the ambient temperature: Compressors are generally more afraid of heat. Try to put them in cooler places. If users have to put them in hotter places, users can try to put them outside, under shade, and away from heat sources. Also, avoid closing or insulating the pipe that dissipates heat from the compressor.
• Operating personnel training: When the Copeland scroll compressor is in use, first familiarize oneself with the operating instructions of the compressor model being used to ensure correct commissioning and operation. Secondly, the operator should also establish a regular inspection system for the scroll compressor, including checking its refrigerant status, electrical system, etc., which will help to discover potential problems of the compressor in time and solve them.
