Foreign objects in the pumped liquid or piping system can block the flow and cause excess heat
generation, sparks and premature failure. Make sure that the pump and systems are free of for-
eign objects before and during operation.
9.
Electrical connections must be made by certified electricians in compliance with all international,
national, state and local regulations.
10. Never operate any pumping system with a blocked suction and discharge. Operation, even for a
brief period under these conditions, can cause confined pumped fluid to overheat. If pump be-
comes plugged, shut down and unplug prior to restarting pump.

WARNING:
•
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.
•
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.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
WARNING:
The coupling guard used in an ATEX classified environment must be properly certified and
constructed from a spark resistant material.
Required parts:
1.
De-energize the motor, place the motor in a locked-out position, and place a caution tag at the start-
er that indicates the disconnect.
2.
Put the pump-side end plate in place.
If the pump-side end plate is already in place, make any necessary coupling adjustments and then
proceed to the next step.
3.
Put the pump-half of the coupling guard in place:
a) Slightly spread the bottom apart.
b) Place the coupling guard half over the pump-side end plate.
