5.2 Installation

Danger of falling!
Installation work for the pump and its accessories is performed directly on the edge of the basin.
Carelessness or wearing inappropriate clothing could result in a fall. There is a risk of fatal injury! Take
all necessary safety precautions to prevent this.
Submerged Base Stand Installation
A separate ring base stand, which is available as an accessory must be fixed at the bottom of the pump. Fix a 90°
elbow to the pump discharge. The pump may be installed with a flexible discharge hose or a rigid pipe, non-return
valve and isolating valve. If a flexible hose is used, make sure that it does not buckle. Fix a chain to the pump
handle and lower the pump into the liquid. If the pump is installed on muddy ground, support it on bricks to
prevent if from sinking in.
Submerged Installation with auto-coupling
Permanent installation of the pumps can be done on a stationary auto-coupling. The following instructions refer
to the use of the original HOMA system.

Place the auto-coupling base unit on the bottom of the pit. Use a plumb line to fix the correct
position of the guide rail bracket on the inside of the pit cover. Drill mounting holes and fasten the
guide rail bracket provisionally with 2 screws.

Put the auto-coupling base unit in the exact position and fasten with expansion bolts to the pit
bottom. If the bottom is uneven, the base unit must be supported to be in horizontal position.

Assemble the discharge pipe in accordance with the generally accepted procedures and without
exposing the pipe to distortion or tension.

Insert the guide rails in the ring of the auto-coupling base and adjust the length of the rails by cutting
them accurately to the guide rail bracket.

Unscrew the provisionally fastened guide rail bracket, fit it on top of the guide rails and fasten it to
the pit cover. Make sure that the guide rails do not have any axial play, as this would cause noise
during pump operation.

Clean out debris from the pit before lowering the pump into operation position.

Fit the coupling flange at the discharge of the pump. Make sure that the rubber profile-seal is
properly fixed to the flange and will not fall off when the pump is lowered into the pit. Slide the guide
bar of the coupling flange between the guide rails and lower the pump into the pit by means of a
chain secured to the pump handle. When the pump reaches the auto-coupling base unit, it will
automatically connect tightly.
