The Marsh ENSIGN ULTRA is rated for a capacity of up to 8 persons.
The structural components of the tank are covered by a 25-year guarantee.
Yes, the compressor system requires a constant electrical power supply to function.
No, professional installation is strongly advised as the unit requires specific excavation and connection to the drainage network to comply with building regulations.
The 250mm riser allows the access point of the tank to sit flush with the final ground level, even if the main body of the tank is buried deeper.
Check the system for a pressure drop; the pressure switch has detected an air supply issue. Inspect the compressor and air lines for leaks or blockages.
Verify that the 200mm AVR unit is installed correctly and that the compressor is sitting level on its mounting base.
Ensure the system is correctly vented and that you are not disposing of harsh chemicals or antibacterial agents into the drains, which can kill the bacteria required for treatment.
Installation must be performed by qualified drainage specialists. The unit is designed for gravity outlet discharge. It is essential to ensure that the surrounding ground conditions are suitable for the tank excavation and that the riser is correctly sealed to prevent groundwater ingress. For care, keep the compressor housing clear of obstructions to maintain airflow. Regularly check the alarm beacon to ensure it remains functional. Routine desludging intervals should be adhered to according to manufacturer specifications to prevent solids from building up in the primary chamber.
