SAFETY WARNING
Electrical Work
All electrical work should be performed by a qualified electrician in
accordance with the latest edition of the National Electrical Code,
local codes and regulations.
Shock Hazard
A faulty motor or wiring can cause electrical shock that could be fatal,
whether touched directly or conducted through standing water. For this
reason, proper grounding of the pump to the power supply's grounding
terminal is required for safe installation and operation.
In all installations, the above-ground metal plumbing should be
connected to the power supply ground as described in Article 250-80
of the National Electrical Code.

* In August 2003 the NEMA pump code was discontinued for all material
numbers created by GRUNDFOS manufacturing companies in North America.
The NEMA version pump code will still remain in effect for existing material
numbers. NEMA version pumps built in North America after this change will
have either an A or U as the pump version code depending on the date the
material number was created.
** If a pump incorporates more than two pump versions, the code for the pump
version is X. X also indicates special pump versions not listed above.
