4. Assembly

4.1 Tank assembly

First insert the circumferential profile seal into thesealing groove in the lower half shell . Lightly coat

the entire seal with the enclosed soft soap.

Then insert the centering pins into thecorresponding slots around the circumference.

The upper half shell should now be positioned onto the lower half shell . Make sure that the seal

doesnt slip out of the groove.

To install the quick connectors , attach them in analternating manner to the left and to the right (counter-clockwise and clockwise). For this, every secondconnector should be adjusted by hand initially, and thendriven securely into place using a hammer and a blockof wood. If attaching the clips is problematic, trylubricating the inner edges of the connectors and/orusing 3 4 C-clamps positioned evenly around the lipof the tank during the installation. Ensure theconnectors are engaged in their final position. After

completing the installation of the first half of theconnectors, repeat the procedure for the remainder

5. Assembling the tank dome and telescopic dome shaft

5.1 Assembling the tank domePrior to actual assembly, the enclosed seal is inserted into the tank domes sealing groove A. Afteraligning the openings of the dome with the pipes, lock the dome onto the tank as demonstrated in theillustration on the right, making sure that the upper seal remains seated during the operation.

NOTE: Once the dome is locked onto the tank it can no longer be rotated.

5.2 Assembling the telescopic dome shaft

The telescopic dome shaft enables adjustment of the tank tosite surfaces with a deviation from level 5. The Minitelescopic dome shaft extends earth coverage between29.5/750 mm and 37.4/950 mm, and the Maxi telescopicdome shaft extends 29.5/750 mm and 41.3/1050 mm.For assembly purposes, the enclosed profile seal (EPDM) isinserted into the tank dome's upper sealing groove and iscoated generously with soft soap (do not use mineral oil-basedlubricants, as these attack the seal). The telescopic dome is

then greased, inserted and aligned with the surface of the site.

5.3 Assembling the adapter

For larger coverage heights, an adapter is needed. Install theadapter between the tank dome and the telescopic dome shaftmaking sure that all seals are lubricated with the soft soap.

With the use if the adapter, the maximum earth coverageshould be 47.2/1.2 meter from the top of the dome shaft tothe top of the tank.(in each case in connection with the Maxi telescopic domeshaft)

6.1 Construction site

When determining where to install the tank, the following should be clarified prior to installation:

- The structural suitability of the ground for this purpose

- minimum depth of water table/maximum groundwater levels and porosity/drainage capability ofthe subsoil

- types of load which will occur above the tank location

In order to determine the soil composition and suitability for the project, local building codes andgoverning agencies should be consulted.

6. Installation

6.2 TrenchTo ensure that sufficient space is available for working, the base area of the trench must exceed thedimensions of the tank by 20/500 mm on each side; the distance from nearby foundations or any

other built structure must be at least 40/1000 mm.The trench embankment must be designed so that slippage or collapse of the embankment wall isprevented. The foundation soil has to be level and must guarantee sufficient load-bearing capability.

The depth of the trench must be dimensioned so that the max. earth coverage (see section 2 instal-lation conditions) above the tank is not exceeded. In order to be able to use the system year-round,the tank and those parts of the system that conduct water must be installed in the frost-free zone ofthe soil profile. Normally, the frost-free depth is between 24 32(60-80 cm), but you should obtainthe information that is specific to your area from local agencies.

A 6 8 (15-20 cm) layer of compacted, pea gravel (grain size 8/16) should be used as a foundation.If the soil has inadequate load-bearing capabilities, areinforced concrete slab (approx. 4 thick) should bepoured to ensure stability.

6.2.1 Slope, embankment, etc.

On installation of the tank in the immediate vicinity (< 16 ft/5m) of a hillside, mound or slope, a statically calculatedsupporting wall has to be constructed in order to accept thesoil pressure. The wall must exceed the dimensions of thetank by at least 20/500 mm in all directions, and must belocated at least 40/1000 mm away from the tank.

6.2.2 Groundwater and cohesive (water-impermeable) soils (e.g. clay soil)

If it is anticipated that the tanks will be immersed

deeper into the groundwater than is shown in theadjacent figure, additional provisions should be made toguarantee sufficient drainage (See table for max.immersion depth).

Installation of a drainage pipe is recommended in thecase of cohesive, water-impermeable soils.

6.2.3 Installation adjacent to surfaces used byvehicles

If the underground tanks are installed adjacent tosurfaces that are used by vehicles heavier thanpassenger cars, the minimum distance away from thesesurfaces is at least the depth of the trench.

6.2.4 Connection of several tanksTwo or more tanks may be connected via thedesignated areas near the bottom of the tanks by

means of manufacturers special seals and (customerfurnished) basic drainage pipes. The apertures mustbe drilled using the manufacturers special crown bit inthe appropriate size. The distance between the tanksshould not be less than 24/600 mm and the pipe mustextend at least 8/200 mm into the tanks.

6.3 Insertion and filling

Lower the tank (or tanks) carefully into theprepared trench. If the tank is inserted intothe water-table, fill it 1/3 full with waterbefore starting to fill in around it. If the tank

is entirely aboved the water-table, this stepmay be omitted, however, partially fillingthe tank prior to back-filling is highlyrecommended.

Fill in the pit around the tank using peagravel (maximum grain size 8/16) in 1 ft (30cm) increments until reaching about 6(15cm) over the top of the tank. At thatpoint you may switch to soil and finish fillingthe trench. Individual layers must be wellcompacted by hand; mechanicalcompaction machines must not be usedunder any circumstances.

6.4 Telescopic dome shaft (pedestrian)

Pedestrian load-bearing dome shaft can handle weights of up to 330lbs/150 kg for short periods, and 110 lbs/50 kg for extended periodsof time.

Important: To prevent loads from being transferred onto the tank,

pea gravel (max. grain size 8/16) is filled in in layers around

the telescope and is evenly compacted. Damage to the tank

dome and telescope must be avoided during this step. The

cover is then positioned and closed to prevent entry by children.Tighten the threaded connection on the cover tightly to

prevent unauthorized access.

6.5 Telescopic dome shaft (passenger vehicle loadbearing)

Vehicle load-bearing dome shafts are designed to bear a maximumaxle load of 4850 lbs.

If the tank is installed under areas used by passenger cars, the

collar area of the telescope (black) must be supported with

concrete (load class B25 = 0.356 psi/250 kg/m). The layer of

concrete to be installed must be at least 12 /300 mm wide andapprox. 8/200 mm high all around.The minimum coverage abovethe shoulder of the tank is at least 31.5/800 mm (max.41.3/1050 mm with telescope, coverage up to max. 47.2/1200

mm possible with intermediate section).

Attention: Use the cast iron cover in all circumstances.
