Operation under freezing conditions
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that will freeze that is inside
the pump and any auxiliary equipment. Failure to do so can cause liquid to freeze and damage
the pump. Note that different liquids freeze at different temperatures. Some pump designs do
not drain completely and may require flushing with a liquid that doesn't freeze.
Temperature ratings
CAUTION:
Do not operate the pump above the rated temperature range of the magnets. This will weaken
or ruin the magnets. The rated temperature is 121°C | 250°F for all sizes.

and disposed of in conformance with applicable environmental regulations.
1.
Slowly close the discharge valve.
2.
Shut down and lock out the driver to prevent accidental rotation.
5.11 Make the final alignment of the pump and driver
WARNING:
•
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.
•
Misalignment can cause decreased performance, equipment damage, and even cata-
strophic failure of frame-mounted units leading to serious injury. Proper alignment is the
responsibility of the installer and the user of the unit. Check the alignment of all drive
components prior to operating the unit.
•
Follow the coupling installation and operation procedures from the coupling manu-
facturer.
You must check the final alignment after the pump and driver are at operating temperature. For initial
alignment instructions, see the Installation chapter.
