Warning
Prior to installation, read these installation and
operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.
Warning
Electrical work: All electrical work should be
performed by a qualified electrician in
accordance with the latest edition of national,
state, and local codes and regulations.
Warning
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.
