2. SERVICE DIAGNOSIS
Lamp
The electrolyzer may also shut down for some error when the flow rate varies for acid water and alkaline water because of different piping resistance ex. connecting hose crushed or one of the water outlets under water. Even if the electrolyzer is in operation, varying flow rate may cause low pH and chlorine concentration. Keep a constant flow rate by balancing the piping resistance
