The commissioning will also provide you with a unique checklist against your system, ensuring your complete peace of mind and reassurance that your system's mechanical and electrical components are in good working order.

    • Check Plant is level, 5 mm tolerance
    • Confirm the ground around the plant is level, flat and that the lid securely fastens
    • Confirm the panel has been mounted correctly
    • Make the required connections to the panel using correct glands
    • Make all electrical connections within the tank
    • Ensure all safety guards are fitted
    • Set all greasomatics within the plant (if applicable)
    • Check belt/chain tension and alignment
    • Check pump float activates freely (pumped discharge only)
    • Check operation of sludge return pump (nitrification plants only)
