Failure |
Failure Cause |
Approach |
Machine turned on but unelectrified |
Power cord is not plugged in place |
Check and ensure the power interface and the power plug is plugged in place and in good contact. |
Fuse burnt-out |
Replace the protective tube in the power socket on the back of chiller. |
Flow Alarm (controller displays E6)use a water pipe directly connect to the water outlet and inlet but still without water flowing |
Water level in the storage water tank is too low |
Check the water level gauge display, add water until the level shown in the green area; And check whether water circulation pipe leaks. |
Flow Alarm occurs while running with other equipment (controller displays E6),but there is water flowing and no alarm whten use a water pipe directly connected to the chiller water outlet and inlet. |
Water circulation pipes are blocked or a pipe bending deformation. |
Check water circulation pipe |
Ultra-high temperature alarm (controller displays E2) |
Blocked dust gauze, bad thermolysis |
Unpick and wash the dust gauze regularly |
Poor ventilation for air outlet and inlet |
To ensure a smooth ventilation for air outlet and inlet |
Voltage is extremely low or astable |
To improve the power supply circuit or use a voltage regulator |
Improper parameter settings on thermostat |
To reset controlling parameters or restore factory settings |
Switch the power frequently |
To ensure there is sufficient time for refrigeration (more than 5 minuets) |
Excessive heat load |
Reduce the heat load or use other model with larger cooling capacity |
Ultrahigh room temperature alarm (controller displays E1) |
The working ambient temperature is too high for the chiller |
To improve the ventilation to guarantee that the machine is running under 40℃. |
Serious problem of condensate water |
Water temperature is much lower than ambient temperature, with high humidity |
Increase water temperature or to preserve heat for pipeline |
Water drains slowly from outfall during water changing |
Water supply inlet is not open |
Open the water supply inlet |
