Graf Risers:

The standard One2Clean invert depth is 630mm minimum for the pedestrian duty cover. This invert can be extended to 830mm with the standard pedestrian Mini Dome. 

Should you require a deeper invert, additional risers can be supplied

• 310mm extension
• 1000mm extension - Can be cut to 550mm or 750mm. 
• The maximum invert for the One2Clean should not exceed 1400mm due to the total tank depth.

GRAF Pedestrian or Vehicle Duty Lid - the standard lid configuration is a pedestrian duty cover and frame,

The Vehicle Duty Lid is suitable for vehicles up to 3.5t for vehicle loading. Tanks supplied with Vehicle Duty Lids must use the Maxi Dome to provide adequate cover over the tank. This ensures a minimum inlet invert of 1000 mm-1060 mm (model-dependent). This can be extended to a maximum of 1420mm. 

Control Panel Kiosk - the standard One2Clean compact controller must be located indoors. In situations where to site this indoors means a distance greater than 20m from the house to the tank, a weatherproof control cabinet is available for the controller.
