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.
2. Pre-installation checklist
2.1 Confirm you have the correct
pump
• Read the pump nameplate to ensure 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?
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.
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
the National Electrical Code. All
wiring must comply with the
National Electrical Code, state,
and local regulations.
