Installation

Lifting and Tank Handling from Truck

Once the truck arrives:

1. Check condition of the tank to ensure no damage has incurred in Transport. All issues must be photographed and sent to AUSTERE PUMPS for verification.

Lifting procedure:

2. Place Soft Slings around the body of the station
3. Slings to be ¼ from each end
4. Connect two leg chains to slings
5. Ensure that angle of lifting is no less than 60 degrees.
6. Lift and Place on Ground
7. Place tank on ground as the same Position of the truck
8. Ensure that the tank is resting on supports. Ensure that the flanges do not come in to contact with the ground.
9. Ensure that the base of the tank is on soft ground (I.E. grass)

Aboveground Horizontal Installation

1. Determine the size of the excavation from the dimensions of the tank and the incoming drain invert depth allowing for a minimum of 200-250mm of concrete around the tank.
2. Excavate allowing for easy placing of the tank and concrete and for consolidating concrete around the bottom half of the tank when backfilling.
3. Place concrete along the centre of the excavation vase and lower the tank into position ‘puddling’ it into the concrete to form a cradle. Consolidate under the tank to prevent voids by hand, do not use vibrating pokers.
4. Check that the tank is truly vertical and level and that the inlet and outlet levels are correct
5. After the concrete has reached its initial set, fill with water according to the given data
6. Continue by placing concrete around the tank at the same time filling with water to equalise pressure and resist flotation. Where the tank is divided into chamber ensure all chambers are equally filled.
7. Connect pipework, seat access shaft into socket and apply waterproof mastic and adhesive, or as applicable.
8. Top up the tank with water to the invert level and place the remained of the concrete to a depth of approximately 250mm above the top of the tank. Where extension shafts are fitted these can be surrounded in concrete once the main tank surround concrete has been set. IMPORTANT: Before surrounding circular or rectangular shafts with concrete, shutter internal to support the sides and safeguard against distortion.
