Jumbo Installation Methods

Stage 1:
Lay a minimum 200mm base of concrete. During this stage case should be taken to ensure that the bottom of the unit is uniformly supported so that point loads to the base are avoided. Connect the incoming and outgoing pipe work preferably using standard UPVC couplings. Please ensure all the units are connected properly and have correct levels, ensure no negative falls are in the system before connection to inlet and outlet pipes.

Stage 2:
Ensure there is an adequate water supply available. It is recommended that the unit is at least half filled with water for ballast and to the unit floating, and then pour concrete around the sides of the tank with a minimum 100mm of concrete around the unit, making sure concrete is packed into the ribs. This will take you to just below the pipe work. Do not use vibrating pokers to consolidate the concrete.

Stage 3:
Should one of our extensions be fitted to accommodate extended invert. This should be backfilled with concrete as detailed above. Please note extensions can only be supplied to 1000mm in line with Building Regulation and Health and Safety. Deeper inverts should be accommodated by use of our access chambers risers (please ask for more details if you are unsure).

Stage 4:
It is important to check the unit has been filled (Primed) with reasonably clean water to the bottom invert or waterline of theoutlet pipe. This is the unit’s normal water level when at rest. Check all pipe connections are clear from obstructions.

Please note: Jumbo Grease Interceptors should not be installed in trafficked situations and in accordance tovBSen1825 should ideally be installed in a compounded area with suitable free access for cleaning/maintenance.
