c. If current operating capacity is higher than 70%, the running capacity will be automatically reduced
by 10%;
d. If current operating capacity is lower than 70%, the running capacity will be automatically reduced 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
speed. The display area alternately displays AL02 and running speed or flow
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 start
• Power Supply fault, disconnected or defective wiring.
• 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 prime
• Empty pump/strainer housing. Make sure the pump/strainer housing is filled with
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, the installation
height of pump 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).
