1. Safety warning

1.1 Read this booklet

This booklet is designed to help a certified
installer to install, begin operation of, and
troubleshoot the Grundfos SuperBrute XL,
UP and UPS pumps.
Following the instructions will ensure safe,
trouble-free operation.
This 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.

1.2 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.
Warning!
Page
A faulty motor or wiring can
5
cause electrical shock that could
5
be fatal, whether touched directly
5
or conducted through standing
5
5 water. For this reason, proper
6
grounding of the pump to the
6
power supply's grounding
6
terminal is required for safe
7
installation and operation.
7
In all installations, the above-
7
9 ground metal plumbing should
10 be connected to the power
10
supply ground as described in
10
the National Electrical Code. All
11
wiring must comply with the

pump
15

• Read the pump nameplate to ensure it is
the one you ordered.
16
17
• Compare the pump's nameplate data and its
17
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?
2.1.1 Pump to system type
recommendations
• Open systems (i.e. potable water):
Stainless steel or bronze volute (pump
housing) only.
• Closed systems (i.e. airless, non-potable
water): Cast iron, stainless steel, or bronze
volute (pump housing).
Other considerations regarding Grundfos
SuperBrute XL, UP and UPS pumps:
• These pumps are intended for indoor use
only.
• If installed outdoors the pump must be
protected by an appropriate, well ventilated,
water-tight enclosure to keep out moisture
and dirt.
• Minimum ambient temperatures must be no
lower than 33 °F (1 °C).
• For ambient and fluid temperature see
sections 2.4 Pumped liquid requirements
and 7. Additional technical data.
