wherever you are working.
Make sure that there are no toxic gases in the working area.
Observe the health and safety at work regulations and make
sure that a first-aid kit is to hand.
In some cases, the pump and the pumping medium may be hot
and could cause burns.
For installations in areas subject to explosion hazards, special
regulations apply!
The sump is a conventional effluent collecting pit in conjunc-
tion with a separately orderd U3 KS or U3 KS special.
NOTICE! Due to the space saving tank design the U3 KS or the
U3 KS can only be operated with the low level float which is part
of the extent of delivery
NOTICE! The connection between the sump and the concre-
te can not be sealed against pressing water. Do not install the
sump in areas with high groundwater levels!
NOTICE! In some countries it must not be used for pumping
sewage water from lavatories.
The allowed temperature of the pumped medium is 35 °C,
short time period 60°C.
The screwed cover is smell-tight and level compensating. The
integrated and smell-tight floor drain can be opend on request.
The PE-tank has two collateral inlet sockets DN 100, offset by
90°, one discharge socket for Ø 40 mm PVC pipe and a vent
socket DN70. The tank neck with its adjustable and rotatable
cover allows an optimized level compensation at the building
site.
Extent of delivery

ded pressure outlet, non-return valve 1 1/4", nipple 40-1 1/4", co-
ver frame with seal, lid with sealing plug usable as a grommet,

Electrical Connection
Please refer to the relevant instructions in the manual for the
pump.
MOUNTING
The pressure tube must be taken in a loop over the local back-
pressure level and secured with a reflux valve. (EN 12056) The
reflux valve is already installed in the BAUFIX 50.
Tank installation
1. Take the parts out of the tank. Do not dismantle the pre-
assembled pipework or the reflux valve, because they are
already sealed.
2. Saw off the tank neck in the required height along the
marked grooves.
3. Push the profile packing with its clamping groove on the
edge of the tank opening. The lips of the seal must be di-
USE
rected to the inside. Grease the seal and push the frame a
little bit declined into the opening. Then adjust it und push
the frame into the opening completely, up to the desired
position (final floor height). The air will escape audible out
of the seal. If the seal is rolled up, the installation must be
repeated.
4. Open the required sockets for the inlet and the ventilation at
the marked positions with a saw or a knife and remove the
burr. Connect the inlet and the ventilation pipes with KG-
sleeves. The pressure pipe must be glued with a PVC sleeve
onto the pressure outlet.
5. After connection of all pipes, the BAUFIX 50 must be lev-
elled and washed in. Do not remove the cover during the in-
stallation to keep the tank clean.
6. At concreting the base, the tank can be secured against
buoyancy by reinforcing steel at the welded wire mash.
.
7. Do not embed the frame in concrete. It should stay adjust-
able to compensate floor pavements or tiles up to 100 mm.
8. Before carrying out the flooring works adjust the frame in
the planed position and fasten it.
9. To allow a wetroom seal to be fitted, the top surface of the
screed must finish flush with the top edge that runs all
round the cover frame.
10. After the screed has set, the enclosed square seal is bond-
ed to the integrated sealing strip. After the customer has
attached a further thin-bed waterproofing system, the area
can be tiled. Information on sealants and adhesives can
be found in the information sheet on "Composite sealing"
issued by the professional association of the German tile
industry within the German Construction Confederation
(ZDB).
Pump installation
1. Seal the pump quarter elbow with Teflon strap and screw it
on the discharge branch.
2. Seal the thread of the pre-assembled pipework with Teflon
strap, screw it in the quarter elbow of the pump and adjust
it as shown below.
3. Unscrew the standard float at the control shaft, replace it
by the low level float and fasten it again with the sheet metal
screw.
4. Push the elastic connector up to the end on the pipework
and fasten it with a hose clamp.
5. Push the hose clamp with the snap buckle on the flexible
connector. Insert the pump in the tank and push the flexible
connector on the reflux valve. Fasten it with the hose clamp.
NOTICE! Ensure the stable position of the pump as well as
the free movement of the float switch!
6. Pull the cable up to the T-piece through the vent pipe.
Enough cable has to be in the tank to allow the pump to be
pulled out of the tank for servicing. The T-piece can then be
sealed with the slotted plug.
