5 Installation at Site

5.1 Safety regulations

DANGER

Improper installation in potentially explosive atmospheres

Explosion hazard!

Damage to the pump set!

▷

Comply with the applicable local explosion protection regulations.

▷

Observe the information in the data sheet and on the name plates of pump and
motor.

DANGER

Risk of ignition by frictional sparks

Risk of explosion!

▷

Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).

▷

If any coupling parts are made of aluminium, a brass coupling guard must be
used.

5.2 Checks to be carried out prior to installation

Place of installation

WARNING

Installation on mounting surface which is unsecured and cannot support the load

Personal injury and damage to property!

▷

Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class XC1 to EN 206-1.

▷

The mounting surface must have set and must be completely horizontal and
even.

▷

Observe the weights indicated.

Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.

5.3 Installing the pump set

Always install the pump set in a horizontal position.

DANGER

Excessive temperatures due to improper installation

Explosion hazard!

▷

Install the pump in a horizontal position to ensure self-venting of the pump.
