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.

2.2 Check the condition of the pump
The pump’s shipping carton is specially
designed around the 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. Once the pump
has been removed from the box, care should
be taken NOT to drop or mishandle the pump.
Box contents:
• one pump
• two gaskets (flanged units only)
• one Installation and Operation Instruction
(I&O).
2.3 Verify electrical requirements
Verify the electrical supply 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.
This pump’s motor is designed to run on
+ / - 10 % of the nameplate-rated voltage.
2.4 Pumped liquid requirements
The pump can be used to circulate:
• Potable hot water.
• Water containing glycol for hydronic heating
(see section 7. Additional technical data for
additional limitations).
• Cooling water.
In domestic hot-water systems it is advisable
to use stainless steel pump housing versions
of this pump.
All pump types (stainless, bronze or cast iron
pump housing) should not be used in water
with a degree of hardness lower than 14 grains
per gallon of hardness.
Fluids should be clean and should not contain
solid particles, fibers, or mineral oils.
If the pump is installed in a heating system, the
water should meet the requirements of
accepted standards on water quality in heating
systems. The fluid should not contain solid
particles, fibers, or mineral oils.
The pump is lubricated and cooled by the
liquid being pumped. Therefore, the pumped
liquid must always be allowed to circulate
through the pump.
Extended periods without circulation will cause
premature wear to the bearings and excessive
motor heat.
The pumped liquid must meet the temperature
requirements listed in the following charts.
Note: Fluid must never be allowed to freeze
during non-operational periods.
The Grundfos SuperBrute XL,
UP/UPS pump is intended for
use with water only. The pump
must not be used for the transfer
of flammable liquids such as
diesel oil, gasoline, and similar
liquids.
The pump is not for pool or
marine use.

3. Installation procedures
3.1 Piping considerations
When making piping connections, be sure
to follow the piping manufacturer’s
recommendations and all code requirements
for piping material.
Thoroughly clean and flush all dirt and
sediment from the system before attempting to
install the pump.
3.1.1 Location in the piping line
The pump should never be located at the
lowest point of the piping system (where dirt
and sediment collect), nor should it be located
at the highest point of the piping system
(where air accumulates).
When installing the pump into the piping
system, Grundfos recommends that pressure
gauges be installed in the inlet and discharge
flanges or pipes. This will allow the pump and
system performance to be checked.
Do not block the pipe plugs in the pump
housing flanges by locating the terminal box
over these plugs.
3.1.2 Mounting positions
The arrows on the pump housing indicate the
direction of water flow. The XL UP/UPS pump
may be installed in vertical or horizontal
piping, but the motor shaft must always
remain horizontal, as shown in fig. 1.
Fig. 1 Installation positions
3.1.3 Terminal box position
At the bottom of the stator, closest to the pump
housing, there are three drain holes to allow
condensed water to escape. The drain holes
shall not be blocked for any reason and one
drain hole must always point downward.
There is not a drain hole directly below the
terminal box; therefore the terminal box must
be positioned in one of the positions shown in
fig. 1 or fig. 2.
3.2 Changing the terminal box
position
If the pump is already installed in the system,
the system must be drained or the isolation
valves on both sides of the pump must be
closed and the pressure released/relieved by
removing the vent plug.
Only after the pressure has been relieved and
the pump drained should you proceed with the
next steps.
Warning!
Never make any connections in
the pump terminal box unless the
electrical supply has been
switched off.
The pump should not be
connected to the electrical
system until it has been properly
installed in the piping system.
Risk of electrical shock — this
pump has not been investigated
for use in swimming pool or
marine areas.
Warning!
The pump must be positioned
so that someone cannot
accidentally come into contact
with the hot surfaces of the pump.
Caution
TM04 5646 3609
Warning!
Before starting any work on this
circulator, be sure electrical
supply has been switched off
and it cannot be accidentally
switched on.
Exercise caution when draining
the system or removing the vent
plug as the fluid in the system
may be scalding hot and under
pressure.
Caution

3.2.1 Rotating the terminal box
To change the position of the terminal box,
follow these steps:
1. Remove the four (5 mm) allen-head screws
holding the pump head onto the pump
housing.
2. Carefully lift/slide the pump head out and
away from the pump housing. Next rotate
the pump head and locate the terminal box
in the desired position. The terminal box
can be rotated in steps of 90 °. Review
fig. 1 and fig. 2 for possible/permissible
positions. DO NOT locate the terminal box
beneath the pump.
3. Make sure the O-ring is properly seated in
the pump housing.
4. Replace the pump head onto the pump
housing.
5. Diagonally tighten the 5mm allen-head
screws evenly.
Torque to: 7 ft lbs. / 9.5 Nm.
6. Check to ensure the rotor turns freely. Do
this by removing the vent plug in the
middle of the pump nameplate. Insert a
medium-size, flat-blade screwdriver into
the slot at the exposed end of the shaft.
Gently turn the shaft. If it does not turn
easily, repeat steps 1 through 5 above.
If the rotor spins freely, proceed to step 7.
Do not put the vent plug back into the
pump until the end of step 9.
7. The position of the nameplate can be
changed by easing the outer edge of the
plate at the cutout with a screwdriver.
Turn the nameplate to the required position
and push into place.
8. Follow electrical instructions in section 3.3.
9. Refill the system, open the isolation valves
and vent the system. Also allow air to vent
out of the pump; once water flows out the
vent hole, replace the vent plug removed in
step 6. See additional instructions in
section 4.1.
10.Fig. 2 shows acceptable terminal box
positions along with recommended drip
loops (dashed lines) in the electrical wiring
harness based on entry point.
Fig. 2 Acceptable terminal box positions
Use caution as the rotor
assembly can fall out of the
pump head or pump housing if
the pump head is pulled too far
away from the pump housing.

3.3 Electrical connection
Proper operating voltage and other electrical
information can be found on the pump name-
plate attached to the top of the motor.
• The motor is thermally protected on all three
speeds and no additional external
protection is needed.
• See fig. 3 for proper grounding and supply
power connection locations (115V and
208-230V).
• The terminal connections are toggle/lever
push design. Push the lever down and
insert the field wiring. Push the lever down
and pull to remove wires.
• Next, use care when installing the terminal
box cover with speed switch (rough
handling can damage the run light LED on
the printed circuit board (PCB)). Insert the
Phillips head screw through the cover and
tighten to a snug fit.
• An external "Drip Loop" is recommended in
the electrical wiring harness; see fig. 2.
• Where an external "Drip Loop" is not
possible, or if the wiring enters through the
upward facing (top) surface of the box, then
an internal "Drip Loop" is recommended;
see fig. 3.
Fig. 3 Examples of ground and power
supply connections (115V and
108-230 V) with internal drip loop
Warning!
Risk of electrical shock!
The electrical connection and
protection should be carried out in
accordance with the latest edition
of the National Electrical Code,
local codes and regulations by a
qualified electrician.
The safe operation of this pump
requires that it be grounded in
accordance with the National
Electrical Code and any state,
local governing codes and
regulations.
Ground wires should be copper
conductors of at least the size of
the circuit conductor supplying
power to the pump. Connect the
ground wire to the grounding
point in the terminal box and then
to an acceptable ground. Do not
ground to gas or water supply
line.
All wire sizes should be copper
and size-based on the ampacity
(current carrying properties of a
conductor) as required by the
National Electrical Code or local
regulations. Additionally UL
requires the following wire sizes
to be used: 18-12 Solid or 14-12
Stranded.
Both the power and grounding
wires must be suitable for at least
194 °F (90 °C).

4. Starting the pump
4.1 Vent the piping system
After the pump has been installed and the
electrical connections made, the piping system
must be vented.
NOTE: Do not vent the piping system through
the pump. Instead, follow these steps:
1. Fill and pressurize the system with liquid,
and vent all trapped air from the piping by
suitable means.
2. If any isolation valves are used, make sure
they are OPEN.
3. Vent the pump by removing the vent plug.
When water exists through the port, the
pump is fully vented / primed.
4. Reinstall the vent plug.
Fig. 4 Vent screw/plug removal for pump
venting
4.2 Speed selection
UPS models
Speeds can be changed via the speed switch
on the terminal box cover. Power must be
turned off before changing speeds. The speed
in the three positions appears in the following
table; also see fig. 6.
UP models
Speed is fixed on Speed 3 (High) and cover
does not have a switch (cover is solid).
Fig. 5 Terminal box cover/lid with speed
switch in medium speed (Speed 2)
Changing to lower speeds offers considerable
reduction in energy consumption and less
noise in the system.
Fig. 6 Pump performance at speed
settings
Never operate the pump dry —
the system must first be filled
with liquid and vented.
Warning!
If the vent screw/plug is to be
loosened, care should be taken
to ensure that the escaping
scalding hot liquid does not cause
personal injury or damage to
components.

5. Troubleshooting
5.1 Fault finding chart
Warning!
Before removing the terminal box cover, make sure that the electrical supply has
been switched off and that it cannot be accidentally switched on.
The pumped liquid may be scalding hot and under high pressure. Before any
removal or dismantling of the pump, the system must be drained or the isolation
valves on both sides of the pump must be closed.
Fault Cause Remedy
1. The pump does not
run. None of the
indicator lights are
on.
a) External circuit breaker
is switched off. Switch the circuit breaker on.
b) Current-/voltage-
operated ground fault
interrupter has tripped.
Repair the insulation defects and reset
the interrupter.
2. The pump does not
run. The green indi-
cator light is on.
a) Rotor is blocked. Switch off the electrical supply and
clean /repair the pump.
b) The speed switch is not
fully positioned (is
between speeds)
Switch off the electrical supply at the
external circuit breaker and change
speed switch into position.
c) The pump has been cut
out by the thermal
overload switch due to
high liquid temperature.
Check that the liquid temperature falls
within the specified range. The pump
will restart automatically when it has
cooled to normal temperature.
3. Noise in the system.
The green indicator
light is on.
a) Air in the system. Vent the system.
b) The pump flow is too
high. Reduce the pump performance.
c) The pressure is too
high. Reduce the pump performance.
4. Noise in the pump.
The green indicator
light is on.
a) Air in the pump. Vent the pump.
b) The inlet pressure is
too low. Increase the inlet pressure and/or check the air volume in the expansion tank
(if installed).
5. The pump runs, but
the indicator light is
off.
a) The LED diode was
damaged when
installing the terminal
box cover or is burned
out.
Switch off the power and change the
printed circuit board or replace the
complete terminal box.
6. Insufficient heat in
some places in the
heating system.
a) The pump performance
is too low. Increase the pump performance, if possible. Flow too fast through the
boiler/heat exchanger may not allow for
the proper BTU transfer to the fluid. If
fluid is too slow, fluid may be cooling too
much before returning from the system.
If changing speeds does not resolve the
problem, replacing the pump with a
properly sized pump may be required.
b) The performance is too
high.

12
5.2 Preliminary checks
Supply voltage
To check the voltage being supplied to the
motor, use a voltmeter.
Single-phase motors
Touch one voltmeter lead to each of the lines
supplying power to the pump as shown in
fig. 7:
• L and N for 115 V and 208-230V circuits
(L = L1and N = L2for 208 - 230V circuits
in the U.S.)
These tests should give a reading of full line
voltage.
Fig. 7 Testing with voltmeter
Evaluation
When the motor is under load, the voltage
should be within 10% (+ or –) of the nameplate
voltage.
Any variation larger than this may indicate a
poor electrical supply and can cause damage
to the motor windings. The motor should not
be operated under these conditions. Contact
your power supplier to correct the problem or
change the motor to one requiring the voltage
you are receiving.
5.3 Current measurement
To check the current using an ammeter, follow
these steps:
1. Make sure the pump is operating.
2. Set the ammeter to the proper scale.
3. Place the tongs of the ammeter around the
leg to be measured.
4. Compare the results with the amp draw
information on the motor nameplate.
5. Repeat for the other legs.
Fig. 8 Current measurement
Evaluation
If the current draw exceeds the listed name-
plate amps, or if the current imbalance is
greater than 5 % between each leg, then
check the following:
• The voltage supplied to the pump may be
too high or too low.
• The terminals/wires in the terminal box or to
circuit breaker may be loose.
• The contacts on the motor starter may be
burned.
• The terminals in the starter or terminal box
may be loose.
• There may be a winding defect. Check the
winding and insulation resistance; see
section 5.6 Resistance charts.
• The motor windings may be shorted or
grounded.
• The pump may be damaged in some way
and may be causing a motor overload.
• A voltage supply problem may exist.
Warning!
Be careful, since power is still
being supplied to the pump. Do
not touch the voltmeter leads
together while they are in contact
with the power lines.

5.4 Insulation resistance
(lead-to-ground)
To check the insulation resistance (lead-to-
ground) of the motor and leads, use a
megohmmeter and follow these steps:
1. Turn the POWER OFF.
2. Disconnect all electrical leads to the motor.
3. Set the scale selector on the megohm-
meter to R x 100K, touch its leads
together, and adjust the indicator to zero.
4. Touch the leads of the megohmmeter
individually to each of the motor leads and
to ground (i.e. L to ground; N to ground,
etc.).
Fig. 9 Insulation resistance measurement
Evaluation
The resistance values for new motors must
exceed 1,000,000 ohms. If they do not,
replace power head.
5.5 Winding resistance (line-to-line)
To check the winding resistance of the motor
windings, use a megohmmeter and follow
these steps.
1. Turn the POWER OFF.
2. Disconnect all electrical leads to the motor.
3. Set the scale selector on the
megohmmeter to R x 1, touch its leads
together and adjust the indicator to zero.
4. Using the charts in section 5.6 for
reference, touch the leads of the
megohmmeter to the appropriate pair of
connectors. Check all pairs that are pres-
ent and write down and label (RA1, RS1,
RS2) all readings.
- In T-box at L & N: UP will = Speed 3/High
- In T-box at L & N: UPS value depends on
the selected speed (Speed 1, 2, or 3)
- For both UP and UPS: with the terminal
box removed, check all combinations RA,
S1, S2
5. Compare your readings to the matching
model, phase and voltage listed in the
charts in section 5.6.
Evaluation
The resistance values must fall within the
tolerances listed in section 5.6. If they do not,
replace the power head.

6. Replacing components
6.1 Removing the pump head
1. Disconnect or TURN OFF the power
supply.
2. Close any isolation valves on either side of
the pump to avoid draining the system of
liquid.
3. Remove the vent plug to relieve any
system pressure retained in the pump.
Exercise caution as the fluid may be
scalding hot and under pressure. Only
after the pressure has been relieved and
the pump drained should you proceed with
the next steps.
4. Disconnect the electrical leads from the
terminal box.
5. Disconnect and remove the conduit from
the terminal box.
6. Loosen and remove the four 5 mm allen-
head screws which connect the pump head
housing to the pump housing.
7. Remove the pump head from the pump
housing. Exercise care as the rotor may
fall out of the stator or pump housing.
8. Clean the machined surfaces in the pump
housing of any foreign material.
6.2 Fitting the pump head
1. Carefully remove the new pump head
assembly from its packaging. Separate the
impeller/rotor assembly from the new pump
head.
2. While holding the thrust bearing plate,
carefully place the impeller/rotor assembly
into the pump housing. The bearing plate
should fit snugly into the lowest machined
surface in the pump housing.
3. Ensure that the impeller/rotor assembly
can rotate freely.
4. Place the O-ring over the rotor and locate it
into the inner diameter of the pump
housing.
5. Carefully place the pump head housing
over the rotor and rotate it so the terminal
box is in the position you wish; see section
3.2.1 Rotating the terminal box.
6. Ensure that the pump head housing is
properly seated on the pump housing. Do
not force the two together — if there is
binding, disassemble them and repeat
steps 2 to 6. Cross-tighten the allen-head
screws evenly.
Torque to: 7 ft lb / 9.5 Nm.
7. Check to make sure the rotor turns freely.
Do this by removing the vent plug in the
middle of the pump nameplate. Insert a
medium-size, flat-blade screwdriver into
the slot at the exposed end of the shaft.
Gently turn the shaft. If it does not turn
easily, repeat steps 1 through 6 above.
