Standard startup procedure is the key to ensuring the normal operation and extending the service life of a home nitrogen generator, and standardized startup can effectively avoid system faults, pressure impact, and molecular sieve damage caused by irregular operation. The complete startup process for household models is divided into pre-start inspection, power-on initialization, system preheating, pressure stabilization standby, and formal gas output, with clear operational specifications for each step, which is easy for beginners to master. First, the pre-start safety and status inspection must be carried out carefully before every startup. Check whether the equipment placement is stable, whether the power cord is intact and plugged into a grounded socket, and whether the air intake filter and gas output pipeline are installed correctly and tightly sealed. Confirm that the gas output switch is in the closed state to prevent instantaneous gas ejection after startup. In addition, check the ambient temperature; the suitable working temperature of home nitrogen generators is 5–35℃, and startup is prohibited in ultra-low or ultra-high temperature environments to avoid system failure.
The second step is power-on and system self-check. Insert the power plug firmly, turn on the main power switch of the device, and the intelligent control panel will light up automatically to start the full-system self-check program. The system will automatically detect internal pipeline pressure, molecular sieve working status, filter blockage degree, and fan operation. The self-check duration is about 2 to 4 minutes, during which all indicator lights will flash alternately, and the fan will run at low speed. Novices must not operate any buttons or cut off the power during the self-check process, otherwise it will cause system program disorder and hidden faults. After the self-check is completed, if the green normal indicator light is on and no fault code is displayed on the screen, the equipment enters the preheating and pressure stabilization stage; if a fault code appears, turn off the power immediately for inspection and restart after troubleshooting.
The third step is equipment preheating and pressure stabilization operation. After self-check completion, the generator will automatically start the air compression and nitrogen separation system, and the internal pressure will rise slowly. Let the machine run idle for 3 to 5 minutes to fully preheat the molecular sieve, stabilize the air compression efficiency, and discharge the residual mixed air in the pipeline. Observe the real-time pressure value on the panel until the pressure stabilizes at the default working pressure (0.6MPa for most household models), and the nitrogen purity value tends to be stable, indicating that the startup preparation is completed. Finally, open the gas output switch according to the usage demand to carry out inflation, gas supply and other operations. After startup and before formal use, continuous idle operation for more than 3 minutes is prohibited without demand, which will cause unnecessary energy consumption and equipment wear. Following this complete startup procedure every time can ensure the stable performance of the nitrogen generator and reduce the failure rate of household equipment in long-term use.
