reduced by 15%;
b. If current operating capacity is higher than 70%, the running capacity will be automatically
reduced by 10%;
c. If current operating capacity is lower than 70%, the running capacity will be automatically
reduced by 5%.
2) Suggestion for non-first displayed of AL01: check the module temperature every 2 minutes.
Compared with the temperature in the previous period, for every 1-degree Celsius increase, the
speed will decrease by 5%.
8.2 Undervoltage protection
When the device detects that the input voltage is less than 197V, the device will limit the current
running speed1
When input voltage is less than or equal to 180V, the running capacity will be limited to 70%;
When the input voltage range is within 180V ~ 190V, the running capacity will be limited to 75%;
When the input voltage range is within 190V ~ 197V, the running capacity will be limited to 85%.
8.3 Trouble shooting
Problem Possible causes and solution
Pump does not • Power Supply fault, disconnected or defective wiring.
start • Fuses blown or thermal overload open.
• Check the rotation of the motor shaft for free movement and lack of obstruction.
• Because of long time lying idle. Unplug the power supply and manually rotate
motor rear shaft a few times with a screwdriver.
Pump does not • Empty pump/strainer housing. Make sure the pump/strainer housing is filled with
prime water and the O ring of cover is clean.
• Loose connections on the suction side.
• Strainer basket or skimmer basket loaded with debris.
• Suction side clogged.
• Distance between pump inlet and liquid level is higher than 2m, height of pump
installation should be lowered.
Low Water Flow • Pump does not prime.
• Air entering suction piping.
• Basket full of debris.
• Inadequate water level in pool.
Pump being noisy • Air leak in suction piping, cavitation caused by restricted or undersized suction
line or leak at any joint, low water level in pool, and unrestricted discharge return
lines.
• Vibration caused by improper installation, etc.
• Damaged motor bearing or impeller (need to contact the supplier for repair).
