Precautions
WARNING:
•
The coupling guard used in an ATEX classified environment must be constructed from
a spark resistant material.
•
Running a pump without safety devices exposes operators to risk of serious personal in-
jury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed.
•
Avoid death or serious injury. Assure mechanical seal guard is properly installed using
supplied fastening hardware.
•
Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
