6.5 Protection against corrosion
A protective coating is applied to the pumps. Remove it before star-
ting-up (see chapter 6.6).
6.6 Removal of protective coating
To remove the protective coating, the pump should be filled and
drained several times using appropriate agents, e.g. solvent naphtha,
diesel oil or alkaline detergent. Flush with water, if necessary.
The pump must be installed and started up immediately afterwards.
6.7 Renewing corrosion protection
If the pump has been supplied with a protective coating and has to
be stored, a new protective coating should be applied after six
months.
For suitable protective coatings, please contact us.
7. INSTALLATING THE PUMP
CAUTION! Installations and electrical connection must be
made by authorised personnel according to the local stan-
dards !
WARNING! Only appropriately authorised personnel may
carry out this work.
WARNING! Electrical connections must be made according
to the European Regulations and Directives for the Standards
in Industry and in compliance with the instructions of the local
power supply utilities of the country concerned.
7.1 Safety measures
- Remove the flange-obturators of the pump right before connecting
piping.
- Connect the pipework carefully to prevent the pumped liquid esca-
ping during operation and endangering operating personnel.
- Ensure that the suction or inflow line, and the discharge line are clo-
sed by valves.
- Ensure that all electrical connections are "dead". Otherwise, there
is a risk of electric shock.
- Pay attention to relevant internal plant regulations.
- Avoid accidental contacts with hot components.
CAUTION! Remove the protective coating by following the ins-
tructions of chapter 5. Otherwise there is a danger of conta-
mination.

7.2 General information

7.2.1 Assembly tools
Special tools are not required for assembly and installation.
7.2.2 Permissible ambient conditions
The ambient temperature can be from -20 °C to +40 °C. The atmos-
pheric humidity should be as low as possible in order to avoid corro-
sion.
7.2.3 Base, foundation
The pump must be installed on a flat floor or foundation free from
vibration. In case of doubt, use vibration dampening feet.
The pump set must be correctly mounted on the foundations. To
avoid distortion of the pump set and/or the foundation, parallel shims
must be used between the base plate and foundation.
Prior to installing, checks should be made with regard to:
- Possible damage to the pump or the pump set that may occur in
transit.
- Ease of running (check that the shaft is free to rotate by hand).
- The foundation dimensions.
The following preparatory work must be carried out before to placing
the pump:
- Roughen and clean foundation surface.
- Remove shuttering/cores from the anchor holes.
- Remove burrs from the anchor holes.
- Check the position and dimensions of the anchor holes against the
arrangement drawing.
7.2.4 Installation of the set
The complete set mounted on the base plate must be carrefully pla-
ced on the foundation in order to center it on hanging bolts.
7.2.5 Space required
The space required for the pump set is set out in the foundation plan
or installation drawing.
Ensure easy access to the shut-off and regulation valves as well as to
any measuring instruments.
7.2.6 Position
In principle the NOS pumps are installed horizontally.

7.3 Motor
Before assembly check the direction of rotation of the motor (indica-
ted by an arrow on the pump casing). If this is not possible the direc-
tion of rotation of the complete unit can only be checked only if the
