2. Introduction

2.1 Safety warning

2.1.1 Read this booklet

This booklet is designed to help a certified
installer install, begin operation of and trouble-
shoot the Grundfos UPS pumps. The booklet
should be left with the owner of the pump for
future reference and information regarding its
operation. Should the owner experience any
problems with the pump, a certified professional
should be contacted.

2.1.2 Electrical work

Warning
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.
Warning
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.

3. Pre-installation checklist

3.1 Confirm you have the correct pump

• Read the pump nameplate to make sure it is
the one you ordered.
• Compare the pump's nameplate data and its
performance curve (for head, gpm, etc.) with
the application in which you plan to install it.
• Will the pump do what you expect it to do?

3.2 Check the condition of the pump

The shipping carton your pump came in is
specially designed around your pump during
production to prevent damage.
As a precaution, it should remain in the carton
until you are ready to install it. At that point, look
at the pump and examine it for any damage that
may have occurred during shipping.
Examine any other parts of the shipment as well
for any visible damage.

3.3 Verify electrical requirements

Verification of the electrical supply should be
made to be certain the voltage, phase and
frequency match that of the pump motor. The
proper operating voltage and other electrical
information can be found on the pump
nameplate.
These motors are designed to run on + / - 10 %
of the nameplate-rated voltage.
Wiring connection diagrams can be found inside
the terminal box cover and later in these
Installation and Operating Instructions. If voltage
variations are larger than + / - 10 %, do not
operate the pump.
