5. COMMISSIONING
5.1 Testing
After the hydraulic and electrical connections have been made, proceed with a system test.
During this step, leave the tank cover partially open to allow levels to be checked.
Fill the lifting station with clean water then check for leaks and check the correct operation of the pump.
For optimal level settings, it is recommended that the discharge gate valve is closed by 3/4.
Check that the emptying operation is carried out correctly at the maximum flow rate of incoming liquid.
caution!
Make sure the pump inside the blueBOX is primed. In some cases, an air bubble may form inside the pump casing, pre-
venting proper pumping of the liquid.
5.2 First start-up
Check that the setting of the pump start and stop levels is correct by simulating a few work cycles with clean water.
Once correct operation has been verified, close the cover with the screws.
6. MAINTENANCE
6.1 Ordinary maintenance
BlueBOX lifting stations are designed and built with high-quality materials to ensure high reliability.
However, periodic cleaning and maintenance are recommended in order to ensure that performance remains consistent over time.
Any work should be carried out by qualified personnel (for example, from the installer's Service Department) in accordance with applicable regu-
lations.
To ensure efficient operation of the product, carry out a verification every:
• quarterly for installation in industrial facilities;
• every six months for installation in multi-family houses;
• annually for installation in single-family houses.
System checks should verify the following:
• absence of deposits at the bottom of the tank;
• absence of any leaks;
• the float switch, if present, can move freely.
• the pump is in the correct position.
Carefully read the operation and maintenance manuals for the pump and electrical control panel to check the frequency and type of periodic
maintenance work required.
After maintenance work is completed, carry out an operation test.
6.2 Safety warnings
When working on the lifting station:
• Disconnect the pump from the power supply and make sure it cannot start-up accidentally. To disconnect the three-phase pump, first discon -
nect the phase conductors then the yellow-green ground conductor.
• Hydraulically isolate the tank (close the inlet and outlet pipe gates).
• Since biological tanks may contain poisonous GASES, ENSURE CORRECT air circulation before starting work.
• Do not immerse your hands or body parts inside the tank and do not touch the discharge pipe if it is metal, without having first disconnected
the electrical power supply to the pump.
• To avoid burns, wait until the pump surface, if previously used, has cooled.
• Wash the pump thoroughly with water or specific detergents.
• DO NOT approach and/or introduce hands or objects into the suction or discharge port of the pump.
• If in doubt, consult the manufacturer before proceeding with any repair or replacement operation.
6.3 Removing the pump from the blueBOX
caution!
DO NOT use the power cable or float to lift the pump. Always use the top handle.
FIXED version
(see Annex 9)
• Unscrew the fastening screws of the cover and remove it;
• Unscrew the cable gland ring nut and remove the power cable;
• Open the collar connection to separate the pump from the system;
• Lift the pump using the top handle and remove it from the tank.
Version with coupling device (see Annex 10)
• Unscrew the fastening screws of the cover and remove it;
• Unscrew the cable gland ring nut and remove the power cable;
• Lift the pump using the top handle and remove it from the tank.
6.4 Replacement parts
When repairing or replacing parts, only use genuine replacement parts.
Use of non-original replacement parts may result in personal injury or damage to property and will invalidate the warranty.
When requesting replacement parts, always specify the serial number and the exact product designation indicated on the nameplate.
