6.1.2 Falling
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.
1. Fall protection harness
2. Anchoring point
• Make sure that all safety guards are in place and secure, and that there is a suitable
barrier around the work area.
• Wear clean slip-resistant shoes.
• Make sure that any ladders or climbing equipment that is used is correctly sized and in
good working condition.
• Never stand in coiled cables, ropes or wires, or between them and the open shaft or
basin.
Diffuser adapter
When the pump is lifted for maintenance, then make sure that the diffuser adapter remains
at the bottom of the column.
6.2 Torque values
All screws and nuts must be lubricated to achieve correct tightening torque. Screws that are
screwed into stainless steel must have the threads coated with applicable lubricants to
prevent seizing.
If there is a question regarding the tightening torques, then contact a sales or authorized
service representative.
