For weights refer to the contract documentation.

Installation requirements

• Protect motors and pumps from the weather.
• Ensure that the workplace is adequately ventilated/heated/
cooled and observe noise protection requirements.
• Check that the transport / taking away of the pump set or its
components to / from installation site is possible without dan-
ger of accident.
Openings must be large enough.
• Adequately rated lifting equipment must be available.
2.5.1 Space required for operation and maintenance
• Ensure that sufficient space, at least from 2 sides, is left for
subsequent maintenance requirements. This space should
have, for reason of good accessibility, min. 0.8 m width.
• The set should be easily accessible from all sides.
• The motor cooling fan requires adequate clearance around
the cowl. Ensure that the air inlet and outlet areas are unob-
structed.
2.5.2 Foundations
• Concrete plinths must be adequately supported in order to
ensure installation safe and functional.
• Length: At least 100 mm longer than the baseplate.
• Width: The fixing bolts should be at least 100 mm in front of
the edge of the foundation.
• Height: 20-30 mm undersize to underlay, adjust and grout
the baseplate. If the plinth is to be tiled, make an additional al-
lowance considering the height of the plaster and the tiles.
• The depth of the foundation should be sufficient to prevent
frost and to be on firm ground.
• Plinths which rest on a structural floor or ceiling should be in-
tegrated into the original construction using bridging rein-
forcement.
• Foundations should contain sufficient mass in order to damp-
en resonant vibrations.
• Do not place rubber, cork, feather and/or resilient mats be-
tween baseplate and plinth.
2.5.3 Supply connections
Check that all supplies like power, water and drainage neces-
sary for installation and later operation are available in the form
required.

3. Mounting/installation

Care and attention to detail during installation are essen-
tial for a trouble-free operation. Incorrect procedures dur-
ing installation may create hazards for personnel or
property or lead to premature failure of the pump.
3.1

Preliminary checks

Check that the dimensions of the plinth/foundation are in ac-
cordance with the drawings.
3.2

Mounting of pump and motor (arrangement A)

See also para. 3.3.
• Common baseplate mounted pump and motor: Adjust the ax-
ial clearance between pump and motor shaft ends.
• Separately mounted pump and motor: Secure the pump onto
the plinth and align it. Then secure the motor and align it with
the pump.
3.3

Installation of assembled pump sets

3.3.1 Horizontal pumps with base plate-mounted drive
motors (E)
• Before lowering the set into position clean the plinth surface
and remove any limewash to ensure sound bonding.
• Hang the fixing bolts with nuts in the baseplate fixing holes.
• Lower the set into position on the plinth surface.
• Place spacer sheets (2) underneath the baseplate (1).
(2)
• Check the alignment of pumps on the flange machined sur-
faces using a spirit level. A margin of error of 1 mm in 1 m is
allowed.
(M)
• When using fixing bolts (3) pour the mounting holes with ce-
ment (4) leaving it proud around the mounting hole (see pic-
ture fixing bolts).
