4 Installation

Before starting work, make sure that the safety instructions 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.

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 rated explosion-proof or intrinsically-safe, then see the

specific explosion-proof information in the safety chapter before taking any further actions.

DANGER: Inhalation Hazard

Before entering the work area, make sure that the atmosphere contains sufficient oxygen

and no toxic gases.

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 during transport.

• Always remove all debris and waste material from the sump before you install the 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.

CAUTION: Fall Hazard

Slips and falls can cause severe injuries. Watch your step.

To minimize the risk of falling, observe the following:

• Use appropriate personal protection equipment when working in or near open basins,

shafts, or trenches.
