Risk of falling!
When installing the pump and accessories, work is
carried out directly on the water's edge! Careless-
ness or wearing the wrong shoes can lead to falling.
This is life threatening! Take all safety precautions to
prevent this.
Submerged installation on ground support ring
Attach the ground support ring (available as an accesso-
ry) with screws to the pump suction nozzle. 90° connec-
tion-elbow or connection loop to the pressure port of the
pump, mount pressure line. Gate valves and check valves
may need to be installed in accordance with local regu-
lations. The pressure line must be fitted free of tension,
when using a hose, ensure it is laid kink-free.
Secure the pump by the handle with a cable or chain, and
lower it into the pumping medium. In muddy ground, put
stones under the pump to prevent it from sinking.
Wet installation with automatic coupling system
The following instructions apply to the installation of the
original HOMA-coupling system:
• Determine the approximate position of the coupling
base and the upper pipe bracket for the guide tubes,
using a plumb bob where necessary.
36 | ENGLISH
• Check the correct installation dimensions of the
pump(s) (see dimensional drawings in the appendix).
• Drill mounting holes for the pipe bracket on the inside
edge of the shaft opening. If this is not possible due
to the space available, the pipe bracket can also be
mounted in an offset position with a 90° folded plate
on the underside of the shaft cover. Provisionally fas-
ten the pipe bracket with 2 screws.
• Align the coupling base to the shaft floor, use a plumb
bob from the pipe bracket - the guide tubes must be
exactly perpendicular! Fasten the coupling base to
the shaft floor with heavy-duty dowels. Ensure that
the coupling base is exactly horizontal! If the shaft
floor is uneven, support the bearing surface accord-
ingly.
• Mount the pressure pipes with fittings free of tension
according to the usual mounting principles.
• Insert both guide tubes into the eyelets on the cou-
pling base and cut to size according to the position
of the pipe bracket. Unscrew the pipe bracket, insert
the tabs into the guide tubes and fasten the bracket
completely. The guide tubes must be positioned with
no play at all, otherwise loud noises will occur during
operation of the pump.
• Clean the shaft of any solid material (debris, stones,
etc.) before commissioning.
• Mount the coupling counterflange of the automatic
coupling system on the pump pressure ports (thread
or flange connection). Ensure that the rubber seal is
firmly seated in position in the counterflange (as a
seal against the coupling base), so that it will not fall
out when lowering the pump.
• Attach the chain to the pump handle or lifting lugs.
Insert the pump with the guide claws of the coupling
counterflange between the guide tubes in the shaft.
Lower the pump into the shaft. If the pump is seated
on the coupling base, it automatically seals itself off
to the pressure line and is ready for operation.
• Hang the end of the discharge chain from a hook at
the shaft opening.
• Hang the motor connection cable of the pump in the
shaft at an appropriate length, with strain relief. Make
sure that the cables can not be bent or damaged.

Dry Installation

For the installation of the pump outside of the collecting
duct, a feed line to the pump housing inlet must be con-
nected. For dry installation, only the models with a motor
cooling jacket are suitable.
The installation of the pump can be either vertical or
horizontal.
• Attach the pump stand or support feet to the pump.
• Mark the position of the pump on the ground, drill and
anchor pump with heavy-duty dowels.
• Use the fittings to mount the suction and pressure
pipes free of tension according to the usual mounting
principles.
