3. Installation1. Excavate hole and prepare base withcompacted gravel (5cm).2. KESSEL Standard inspection chambers areeasy to handle and place in excavation.3. Saw off tips of necessary inlets / outlet atrecessed cut marks.4. Connect to required pipes.5. Backfill with gravel and compact at equalincrements of max 50 cm.6. Standard polyethylene cover (H=140 mm)5

4. Installation in traffic areasAttention:When installing the chamber, makesure that the elevation differencebetween inlet and outlet of chamberis 1.5 cm..(Outlet is 1.5 cm lower than inlet)InletOutletImportant during installation :Elevation difference between inlet and outlet is 1.5cm4.1 Installation in load class A (1.5 ton) and load class B (12.5 ton) areasFor installations in load class A and Bareas it is important to firmly compactthe upper section into the ground afterthe backfilling around the uppersection. This is accomplished byplacing a heavy duty steel plate overthe upper section and running a soilcompacter over the upper section andthe area surrounding it.4.2 Installation in load class D (40.0ton) areasIn load class D (40.0 ton) areas theKESSEL chamber should be installedaccording to the RstO in coordinationwith the ZTVE-StB and DIN 18196.The KESSEL chamber will be equippedwith the KESSEL upper section ArticleNumber 860122 and standard BEGUmanhole covers.In Class D installation without anapproved road surface, a concrete(with steel re-enforcement) supportplate is required. This plate should becast around the upper section, shouldbe 2 x 2 meters in area and have a depth of 150 mm. A diagram of this re-enforcementplate is available from KESSEL upon request.6
