2 Installation and Commissioning
2.1 Installation instructions
The aeration unit AQUA 8 consists of a
separable float with suction pipe (1) and the
motor unit with propeller and distributor (2). All
materials are made of V2A stainless steel or
plastic and are thus suitable for use in
wastewater.
For tank openings (3) smaller than 800mm, the
two-part float can be opened on one side and
inserted into the tank. It must then be screwed
back into the tank. The clear diameter of the tank
opening should be at least 600mm. When
delivered, both halves of the float are usually
only screwed together hand tight.
The intake pipe is to be screwed together with
the float to form a unit. To do this, turn the
pontoon upside down and screw the stainless-
steel pipe to the float using the retaining
brackets. To do this, use the corresponding
threaded inserts on the pontoon and the drill
holes in the stainless-steel pipe.
The float with suction pipe is then positioned on
the tank bottom centrally under the maintenance
opening.
Then the positions for the heavy-duty anchors of
the guide chains are measured in the area of the
tank opening so that the chains can run vertically
at a distance of approx. 75 cm through the guide
elements on the float and can hang down to the
tank bottom.
For the assembly of the guide chains, the
turnbuckles are turned up to maximum length
and fastened to the heavy-duty anchors with ring
nuts and shackles. The vertically hanging guide
chains determine the lower fixing points. The
lower heavy-duty anchors are now mounted here
and connected to the lower chain ends. The
chain must be shortened to the required length.
Attention Free chain ends can be sucked in by
the aerator and cause damage.
The guide chains are then tensioned over the
turnbuckles and fixed with the lock nut.
