5. Installation and Start-Up

5.1. General

In order to prevent damage to the pump or serious injury
during installation the following points must be observed:
• Installation work may only be carried out by qualified
persons. The safety instructions must be followed at
all times.
• The pump must be inspected for damages before any
installation work is carried out.
• If you are using level control, make sure that the min-
imum water coverage is present.
• Air pockets may not be allowed to enter the pump
housing or the pipes and they must be removed with
a suitable ventilation system or a small inclination of
the pump.
• Protect the pump from frost.
• The operating area must be laid out for each machine.
You must ensure that lifting gear can be fitted without
any trouble, since this is required for assembly and
removal of the machine.
• The maximum bearing capacity must be greater than
the weight of the machine, add-on units and cable.
• Electric power cables must be laid out in such a way
that safe operation and non-problematic assembly/
dismantling are possible at all times.
• The electric power cables should be fastened prop-
erly to the pipes with cable holders or other suitable
equipment. This should prevent loose hanging and
damage to the electric power cables. Depending on
the cable length and weight, a cable holder should be
fitted every two or three meters.
• The structural components and foundations must be
of sufficient stability to ensure safe and functional op-
eration. The operator or supplier is responsible for the
provision.
• Never let the unit run dry. Therefore, we recommend
installing a level control unit.
• Use defector plates for the pumped fluid intake that
air cannot introduce into the pumped liquid. This will
lead to that the pump will run smoothly and is sub-
jected to higher wear and tear.

5.2. Installation

Danger of falling!
Installation work for the pump and its accessories
is performed directly on the edge of the basin. Care-
lessness 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 acces-
sory 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 han-
dle and lower the pump into the liquid. If the pump is in-
stalled 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.
