General and Safety Information
With the AQUAmax®one is concerned with a technical system which, in combination with a multi-
chamber tank, is employed as small wastewater treatment plant for the aerobic biological treatment
of domestic and comparable wastewater of up to 75 PE from single or several buildings.
Dimensioning, design and operation are to take place up to 50 PE in accordance with EN 12566-3.
With employment in accordance with regulations no hazards whatsoever emanate from the plant. If
the AQUAmax®is used for other purposes without the explicit approval of ATB WATER GmbH
and/or the following safety information is ignored, this can lead to the hazarding or injury of
persons and to malfunctions or defects in the plant. In this case any liability is excluded,
Modifications to the plant or unauthorized conversion is not permitted.
The AQUAmax®and accessories are not intended to be used by persons (including children) with
limited physical, sensory or mental capabilities or due to a lack of experience and/or knowledge,
unless they are supervised by or receive instruction from a person responsible for their safety, as
to how the AQUAmax®and accessories are to be used. Children are to be supervised in order to
ensure that they do not play with them.
Before use the AQUAmax®is to be installed correctly and in agreement with the installation
instructions. Installation instructions, operating and maintenance instructions are to be read
thoroughly and the instructions included therein are to be followed implicitly.
With assembly and installation, commissioning and operation as well as, if required,
decommissioning, national standard specifications and regulations are to be complied with. All
tasks may be carried out by trained and qualified specialists with appropriate certificate of technical
qualification. The operator is to be instructed by the fitter.
With the connection of the control system the national applicable regulations and the details on the
type plate are to be complied with (mains voltage, frequency etc.). The equipment is to be operated
on a network which includes a protective earth conductor (PE). Attention is to be paid to correct
phase connection (even with plug-in design)! The connection to the mains must take place by
means of separate fusing and residual current protective circuit breaker. Before commissioning,
the correct function of the electrical protective measures must be checked!
The installation work is to be carried out by qualified electricians only. With work on the equipment
fundamentally the mains plug is to be disconnected. A separation or extension of the cable is not
permitted. The electrical connection data is to be taken from the type plate on the equipment.
Operate no equipment which has a damaged connector/connection cable or plug, which indicates
a malfunction, has been dropped or has been damaged in any way.
With all maintenance and repair work the plant is to be disconnected from the mains. The
AQUAmax®can be removed easily from the tank. If the plant is to be climbed into, this may take
place only with the presence of a second person (this is fundamental!). Particular care is to be
taken. The applicable accident prevention regulations and rules of technology are to be complied
with.
In the versions with submersible aerator the AQUAmax®feeds the required air to the wastewater
through a rapidly rotating propeller. Never work in the vicinity of the aerator as long as the
AQUAmax®is connected with the mains. Danger of injury!
The correct function can only be guaranteed with the employment of original spare parts or spare
parts approved by ATB. Before commissioning, all points of the operating instructions are to be
checked. Keep these instructions readily to hand at all times!

Services to be Provided by the Customer
•The tanks are to be offset to the appropriate height and are to be watertight
•A watertightness test has been carried out and completed successfully. For this the installation
instructions of the tank manufacturer are to be complied with.
•All chambers of the plant are to be accessible for people (clear openings at least 60 cm
diameter).
•The cover of the tank with the aeration chamber must have ventilation openings. In addition a
ventilation facility at the outlet pipe plant is strongly recommended. The correct ventilation via
the roof is to be ensured.
•The outlet pipeline is connected to the manhole and protrudes ca. 15 cm into the manhole (do
not cut off at the manhole wall!).
•Behind the wastewater treatment plant there is a further distribution, monitoring or percolating
manhole. If this is not the case then a sampling possibility is to be installed in the SBR tank.
•A 230 V energy supply is to be laid and fused separately as follows: B 16 A, and residual
current circuit breaker 25 A / 30 mA.
•A cable pipe is to be laid between the control unit and the wastewater treatment plant. The
diameter should be at least 10 cm. No bends with a greater curvature angle than 30° are to be
laid. The cable pipe is to be sealed against odours.
•A draw wire is planned in the empty pipe. The maximum distance between control unit and
AQUAmax®for plug-in variants is 35 m, for plants with compressed aeration (ZB) 12 m.
•The tank is free of wastewater and cleaned.
•The AQUAmax®incl. accessories are on the construction site at the start of assembly.
•The partition wall between aeration stage and sludge storage is to be produced watertight and
provided with an emergency overflow (ca. 10 x 4 cm) in the upper area (single tank plant).
•The maximum difference between lower edge runoff and upper edge partition wall is 30 cm
(AQUAmax®BASIC and M configurations).
•The inlet pipeline is connected to the primary settling stage. With retrofitting this, as a rule, has
been relaid (Note drawing "Tank preparation" or project sketch).

Assembly Drawing AQUAmax® CLASSIC Z
Switch-off Point Float Switch (HW,min), all Types
The switch-off point of the float switch for all types is at the
height of the centre selvedge between upper and lower
part of the aerator housing. The difference (= HW,min)
between this point and the bottom of the tank should not be
exceeded.
The values for HW,min are to be taken from the data sheets
or the wastewater engineering calculations.

Preparation of the AQUAmax®
AQUAmax®BASIC
Before locating the AQUAmax®BASIC in the cesspit, check the mounting bracket for the correct,
and for the number of connected inhabitants, matching position. The lower position of the mounting
bracket is provided for 4-8, the upper for 9-16 PT (see also the stamp on the plastic bodywork). If
required, loosen the securing screw and relocate the mounting bracket.
AQUAmax®CLASSIC Z / ZB
Secure the stainless steel hooks supplied in such a way on the tank cover that the
AQUAmax®is positioned as far as possible centrally in the tank. See to it that the pipeline
outlets for sludge and clarified water are approximately pointing in the direction of the
appropriate inflow and outflow pipelines. Connect the outlet hose (25 mm) with the
AQUAmax®by means of a coupler connection.
Now suspend the AQUAmax®on the chains supplied so that the float switch-off point agrees with
HW,min. The slope of the tensioned chain should not be more than 45° to the vertical.

Art.-No.: 9060 0209 / Status: 17.01.2019 / Page 14 from 24
Installing AQUAmax®
A communicating tube forms the connection to the primary chamber. This system
works only with absolute tightness! Please ensure that cables and hoses are long
enough so that the AQUAmax® can be easily take out of the tank. Cables must not be
subjected to tensile stress.
AQUAmax®BASIC, CLASSIC M
AQUAmax®BASIC, CLASSIC M are placed centrally on the partition wall. The immersion pipe
must dip into the 2nd primary settling chamber (not the inlet chamber). With single-chamber primary
settling an additional protective pipe or a scum board is to be provided for the immersion pipe.
Connect the outlet hose with the AQUAmax®by means of a coupler connection.
AQUAmax®CLASSIC Z / ZB
With the AQUAmax®CLASSIC Z push the 30 respectively 40 mm PVC hose through the
connecting pipe to the primary settling stage and, using the coupler connection screw on to the
sludge pipe. Lay the hose in such a way that this does not sag. Secure the sludge pipe using the
enclosed pipe clips such theat the inlet opening is at the height of HW,min. Connect PVC hose and
immersion pipe by means of the enclosed hose clips. If required, the immersion pipe must be
secured against the ingress of thick matter floating sludge (see below).

AQUAmax®with compressed aeration (AQUAmax®ZB)
As an alternative to the submerged aerator, the CLASSIC Z versions can be supplied with air via
one or two compressors and a corresponding number of membrane tube aerators.
An exemplary illustration of the installation with two compressors can be seen in the following
figure.
The compressor outputs are connected to the air adapter using a 25 mm fabric hose in the shortest
possible way (not required if only one compressor is provided). This is also connected to the air
distributor Multi and through the empty pipe in the tank with a 25 mm fabric hose. From here, the
air is routed to the membrane diffusers via a 16 mm fabric hose.
The air distributor is prepared for mounting in the tank above the water level or near the tank
opening.
The membrane aerators are to be placed on the bottom of the biology so that an optimal aeration
pattern is guaranteed. Because of their weight, they can be positioned without separate
attachment.
At the AQUAmax® 1-16 ZB, the air is supplied via a 16 mm fabric hose, which is laid directly from
the compressor through the empty tube into the tank. This is connected directly to the membrane
air diffuser in the case of the quarter-chamber version or via a Y-piece in the case of the half-
chamber version (see next page).

Sampling bottle
Up to 16 PE and over 51 PE red connection cover, 17-50 PE blue connection cover!
The sampling bottle is attached to the cone of the sewage treatment plant with a holder. The holder
should be provided where is no obstacle when removing the AQUAmax®.
Cut the outlet hose to length and place it on the inlet nozzle of the sampling bottle (note the
marking/flow direction!).
Put the remaining hose on the outlet spout and push it into the outlet so far that the clear water
cannot flow back. Secure the hose with a pipe clamp to prevent it from slipping out. If a non-return
flap is installed in the clear water hose or if the sampling bottle is mounted significantly higher than
the outlet, further action may be necessary. In these cases, please contact our service department.
Sufficient space must be ensured for removing the bottle.
Sampling-Bypass
For variants over 50 PE, a sampling bypass is included in the scope of delivery.
The sampling bottle represents a bottleneck which, in the case of larger systems, means that the
clear water discharge takes up an increasingly unfavourable amount of time. This is prevented by
the bypass, because a part of the clear water flow is routed around the sampling bottle.
Observe flow

Assembly
Using the mounting materials provided secure the ATBcontrol© 3 to the casing provided for this and
to a suitable, as far as possible, weather-protected position.
The ATBcontrol© 3 is supplied as plug-in variant. Cabling on site is dispensed with.
For the AQUAmax® ZB with compressed aeration, the control unit is already mounted on a
mounting plate. This can be mounted directly on the wall or in an outdoor cabinet.
Next to the control unit there is a distribution box on the mounting plate to which the AQUAmax® is
connected, as well as the sockets for the control unit (and mains cable) and the compressor(s).

All tasks, which nevertheless require an opening of the control unit, are to be carried out by
a qualified electrician!
ATTENTION! Before opening the ATBcontrol© 3 and/or the connection box it/they
must be disconnected from the mains supply. Work on opened units may be
carried out exclusively by qualified electricians! Pay attention to phase-correct
connection (even with plug-in design)!
As you are concerned with an electrical plant with submerged motor units, a
separate B16 fuse and a (separate) upstream 30 mA ELCB (earth leakage circuit
breaker) is absolutely essential!
Attention is to be paid to correct laying of the protective earth conductor up to the
earthing of the building.
