on page 2 have been read and understood.
DANGER: Electrical Hazard
Before starting work on the unit, make sure that the unit and
the control panel are isolated from the power supply and
cannot be energized. This applies to the control circuit as
well.

phere contains sufficient oxygen and no toxic gases.
Hazardous atmospheres
DANGER: Explosion/Fire Hazard
Special rules apply to installations in explosive or flammable
atmospheres. Do not install the product or any auxiliary
equipment in an explosive zone unless it is rated explosion-
proof or intrinsically-safe. If the product is EN/ATEX-, MSHA-
or FM-approved, then see the specific EX information in the
Safety chapter before taking any further actions.
WARNING: Explosion/Fire Hazard
Do not install CSA-approved products in locations that are
classified as hazardous in the National Electric Code(TM),
ANSI/NFPA 70-2005.

General requirements
These requirements apply:
• Use the pump dimensional drawing in order to ensure proper in-
stallation.
Before installing the pump, do the following:
• Provide a suitable barrier around the work area, for example, a
guard rail.
• Make sure that equipment is in place so that the unit cannot roll or
fall over during the installation process.
• Check the explosion risk before you weld or use electric hand tools.
• Check that the cable and cable entry have not been damaged dur-
ing transport.
• Always remove all debris and waste material from the sump, inlet
piping, and discharge connection, before you install the pump.
• Always check the impeller rotation before lowering the pump into
the pumped liquid.
NOTICE:
Do not run the pump dry.
NOTICE:
Never force piping to make a connection with a pump.
Authority regulation
Vent the tank of a sewage station in accordance with local plumbing
codes.
Fasteners
• Only use fasteners of the correct size and material.
• Replace all corroded or damaged fasteners.
• Make sure that all the fasteners are correctly tightened and that
there are no missing fasteners.
4.1.1 Install with Wet well installation
In the wet-well installation, the pump is installed on a stationary dis-
charge connection, and operates either completely or partially sub-
merged in the pumped liquid. These requirements and instructions on-
ly apply when the installation is made according to the dimensional
drawing.
