2. Notes
2.1 Safety
Observe the national accident prevention regulations during all wor . Particularly for inspecting the tan s,
a second person is required for safety reasons.
Furthermore, observe the valid national regulations and standards during installation, assembly, mainte-
nance and repair wor , etc.
During all wor on the system or parts thereof, always shut down the entire system and secure it against
unauthorised re-start.
Always eep the tan cover closed, except when wor ing in the tan . Otherwise, there is a high ris of an
accident occurring. Only genuine GRAF covers or covers that GRAF has approved in writing must be
used.
GRAF offers an extensive range of accessories, which are all coordinated to one another and can be
expanded to form complete systems. The use of accessories that have not been approved by GRAF re-
sults in the exclusion of the warranty/guarantee.
2.2 Ventilation and bleeding
All tan s must be ventilated and bled. Additional ventilation lines or ventilation openings must be ordered
if necessary. Ventilation lines should be ordered to guarantee natural ventilation (chimney effect).
Bleeding with a free outflow Bleeding with percolation or an obstructed outflow

3.Construction and functional principle
15 / 33
3. Construction and functional principle
The small wastewater treatment system is fully biological and wor s according to the retention process
with long-term aeration. The system is made up of an aerobic stage. A scum board is used to split this
stage into a coarse substance chamber and an activation chamber. The chambers are connected to one
another in the bottom section. During this process, therefore, all domestic sewage is immediately exposed
to aerobic wastewater treatment. The entire system is aerated due to compressed air being blown in and
the sludge activated as a result of this biologically cleans the wastewater.

. Assembling the set-up kit
1. 2.
Unfold the scum board. Place the clamps on ei-
ther side of the folding edges.
Insert the scum board into the upper shell. A
groove offsets in an off-centre position.
3. 4.
The fixing clamp has to be pushed with the
rounded stic in to the baffles side. The fixing
clamp has to be fixed.
Once the baffle has been positioned perforate the
inner rib directly above the wall using an 8mm. drill
head.
Perforate the baffle 4 cm. from its edge using the
same 8 mm. drill head.
5. 6.
Pass a cable tie through both holes and tighten it.
Cut the excess cable tie.
Repeat this procedure on the opposite side
Continue assembling the Carat RS tan according
to the installation instructions (seal, centring pins,
lubricant).

7. 8.
Place the upper shell with the scum wall on top of
the lower shell. Assemble the clamps for con-
necting the upper and lower shells.
Assemble the clamps for connecting the upper and
lower shells.
9. 10.
Drill the inflow and outflow with a DN 100 core
drill (with a diameter of 124 mm).
De-burr the hole. Insert the DN 100 lip seal. In the
case of the outflow, the direction of the feed-
through must be from the inside out. Affix the “Out-
flow” stic er.
11. 12.
Slide the outflow pipe through the outflow hole
from the inside.
The jac base must be turned depending on the
tan size. The specified tan size on the base must
be the same as on the jac .

Depending on the tan size, the length of the jac
must be adjusted by moving the jac base. The
rough position is specified on the jac . The exact
height is to be determined inside the tan .
Assemble the jac and sampler. To do this, push
the jac outflow into the sampler hole.

Push the jac into the sampler (until it snaps into
place).
Insert the jac into the tan along with the sampler.
17. 18.
Insert the jac into the profile for holding the parti-
tion wall from above.
Insert the sampler’s outflow connection into the
sleeve of the outflow pipe (use lubricant!). The
sleeve connection must be secured with a Spax
screw.

The cord must be secured to the pipe aerator (6
mm hole). The air hose (19 mm) must be con-
nected on the opposite side. Systems for more
than 7 inhabitants have two pipe aerators.
Position the pipe aerator(s) on the bottom of the
tan . It must be slid under the scum board such that
even the first chamber is ventilated. To attach the
cord, a hoo is fitted inside the tan dome. The hole
for the hoo should be pre-drilled with a 4mm bit.
21. 22.
In systems with two pipe aerators, use a Y-
piece to join the hoses of the two pipe aerators.
Assemble the tan dome according to the installation
instructions (seal!).
23. 24.
Secure the sampling tan to the tan dome with
a Spax screw.
Connect the air hose (13 mm) to the in-feed jac .

1. 2.
The control must be installed in a dry and dust-
free interior. Two 8 mm holes must be drilled
into the wall for assembly.
Secure the control to the wall using the dowels and
screws provided.
3. 4.
Position the compressor on the control. Connect
the compressor to the control unit pipe using the
90 Deg hose piece and hose clamps provided.
Plug the compressor plug into the control soc -
et.
Connect the air hoses to the control’s hose nozzles.

Please refer to the installation instructions for
the External Cabinet for electrical connection
details.
Before installing the control unit, a strip of foam rubber
must be glued to the bac of the control unit.
3. 4.
The Control Unit should be mounted to the
external cabinet with the screws and wing
nuts provided.
Position the compressor on top of the Control Unit and
connect together using the 90 Deg hose piece and
hose clamps provided.
