ELECTRICAL HAZARD
Risk of electrical shock. Make sure no one gets closer than 20 m or 65 ft. to the unit when being in contact with
the pumped or mixed liquid.
NOTICE
The noise level of the product is lower than 70 dB However, the noise level of 70 dB may be exceeded in some
installations and at certain operating points on the performance curve. Make sure that you understand the noise
level requirements in the environment where the pump is installed. Failure to do so may result in hearing loss or
violation of local laws.
1. Check and verify the nameplate for output and voltage required for the pump.
2. Check the wiring, power supply voltage, the capacity of the ground leakage circuit breaker, etc.
3. Start the pump.
Trial Operation Non-Float Switch
Run the pump for a short time (1 to 2 seconds) and verify the direction if the rotation of
the impeller. If the starting jerk is counterclockwise (seen from above), the direction of its
rotation is correct. If the direction of rotation is incorrect, two of the wires should be
switched (consult a certified electrician).
CAUTION
• Make sure to check the pump's direction of rotation while the pump is not
submerged in water. Otherwise, the pump will get damage, which may lead
to current leakage and electrical shock.
• Never hold the handle while checking the direction of rotation. The starting
jerk may be very violent.
•
Operate the pump from 3 to 10 minutes and perform the following checks:
•
Using an AC ammeter (clamp), measure the operating current at the phases U, V, and W that are
connected to the terminal board.
• Using an AC voltmeter (tester), measure the voltage at the terminal board.
Conditions Description
Rated Output Variation ±10%
Voltage Variation without overheating ±10%, provided that it does not run
Frequency Variation ±1%
• Proceed with the normal operation if no abnormal conditions are found during the trial operation.
