1. Check whether the power is on before starting the machine. The outdoor environmental protection air conditioner is forbidden to be close to all fire sources; in the case of thunder, the power switch should be cut off as far as possible.
2. In the absence of special circumstances (except for places that need to be turned on for 24 hours), the power should be turned off when no one is using the environmental protection air conditioner on or off duty, so that the air conditioner can be shut down for rest after several hours of operation, so as to increase the operation life and performance of the environmental protection air conditioner. When shutting down, the switch of the wall controller should be turned off first, and then the power supply should be cut off. It is not allowed to turn off the power switch directly when the environmental protection air conditioner is running. If the environmental protection air conditioner is found to be uncooled or not ventilated during use, the fault information of the wall controller should be checked, and the environmental protection air conditioner should be turned off, waiting for after-sales service.
