3. Product description
3.1 Introduction
Grundfos pumps are carefully inspected and
tested before shipment. This pump should
provide long, efficient, trouble-free performance.
To ensure maximum performance and reliability,
please follow the simple instructions in this
manual.
When installing this pump, always follow basic
safety precautions and any federal, state, and
local requirements.
3.2 Delivery and handling
Examine the components carefully to make sure
no damage has occurred to the pump during
shipment. Take care to ensure the pump is
NOT dropped or mishandled; dropping will
damage the pump.
3.3 Pre-installation checklist
Before beginning installation procedures, the
following checks should be made. They are all
important for proper installation of the circulator
pump.
3.3.1 Applications
Model UP(S)15, 26, 43 and 50 series pumps are
generally designed to circulate water from
+32 °F to +230 °F (0 °C to +110 °C) up to a
maximum pressure of 150 psi (10 bar).
Some models have temperature limitations
which are shown in Table A below. If required,
a 50 % by volume solution of ethylene or
propylene glycol and water can be used;
however, a decrease in pump performance may
result due to an increase in the viscosity of the
solution. Check with manufacturer for
information regarding suitability of pumping
other liquids.
Closed systems
Model UP(S) 15, 26, 43 and 50 series pumps
with cast iron pump housings are designed to
pump water compatible with their cast iron
construction. They are recommended for use in
closed hydronic systems
(i.e. airless, non-potable water).
Open systems
Model UP(S) 15, 26, 43 and 50 series pumps
with stainless steel or bronze pump housings
are designed to pump water compatible with
their construction and can be used in both open
and closed systems.
3.3.2 Maximum water temperature
The maximum allowable water temperature is
determined by the ambient or surrounding air
temperature as shown in Table A.
3.3.3 Inlet pressure requirements
The pressure required at the inlet of the pump is
a function of the temperature of the water as
shown in Table B.
In a pressurized system, the required inlet
pressure is the minimum allowable system
pressure.
In a system open to the atmosphere, the
required inlet pressure is the minimum distance
the pump must be located below the lowest
possible water level of the water source
(tank, pool, etc.).

4.1 Position of terminal box
Proper installation of the pump will have the
terminal box located to one side of the pump or
the other, with the conduit entry down.
See fig. 1.
Fig. 1 Recommended terminal box
4.2 How to change the terminal box
How to change terminal box position:
1. Remove the four (4) hex socket head screws
2. Carefully separate the stator from the pump
3. Replace the hex socket head screws and
4. Check that the impeller turns freely. If the

box orientation.

impeller does not turn easily, repeat the
disassembly/reassembly process.
4.2.1 Pump mounting: for indoor use
When making pipe connections, be sure to
follow the pipe manufacturer's recommendations
and all code requirements for piping material.
Arrows on the side or bottom of the pump
housing indicate direction of flow through the
pump. Grundfos circulator pumps can be
installed in both vertical and horizontal lines.
The pump must be installed with the motor shaft
positioned horizontally.
Under no circumstances should the pump be
installed with the shaft vertical or where the
shaft falls below the horizontal plane.
See fig. 2.
TM05 5563 3812
Fig. 2 Acceptable pump mounting
We recommend that isolating valves be installed
on each side of the pump. If possible, do not
install elbows, branch tees, and similar fittings
just before or after the pump. Provide support to
the pump or adjacent plumbing to reduce
thermal and mechanical stress on the pump.
positions
4.3 Installation requirements
1. Thoroughly clean and flush the system prior
to pump installation.
2. Do not install the pump at the lowest point of
the system where dirt and sediment naturally
collect.
3. Install an air vent at the high point(s) of the
system to remove accumulated air.
4. Ensure that water does not enter the
terminal box during the installation process.
5. Open system: Install the pump in the supply
line; the suction side of the pump should be
flooded with water. Ensure that the static
head requirement from Table B is achieved.
6. Closed system: Install a safety relief valve to
protect against temperature and pressure
build-up.
7. If the water contains suspended particles, we
recommend that a strainer and/or filter be
installed and cleaned regularly.
Do not start the pump until the
system has been filled.
4.3.1 Check valve removal
1. Use needle-nose pliers to remove check
valve from pump housing.
2. Check to make sure no part of the valve
remains in the pump housing.
3. Apply the enclosed round "Check Valve
Removed" label over the check mark symbol
located on the nameplate of the pump.

5. Electrical installation
Warning
All electrical work should be
performed by a qualified electrician
in accordance with the latest
edition of the National Electrical
Code and local codes or
regulations.
Warning
The safe operation of this pump
requires that it be grounded in
accordance with the National
Electrical Code and local codes or
regulations.
Warning
The ground conductor should be a
copper conductor of at least the
size of the circuit conductor
supplying power to the pump.
Minimum ground conductor size is
14 AWG. Connect the ground
conductor to the grounding point in
the terminal box and then to an
acceptable ground.
Warning
Do not ground to a gas supply line.
Warning
For fig. 3, some pump models may
come with two access wiring ports
(cable entries) to the terminal box.
To ensure safe operation of your
installation, the enclosed terminal
box cap (blanking) plug MUST be
inserted into the unused wiring
access port (cable entry).
The proper operating voltage and other
electrical information can be found on the
nameplate attached to the top of the motor.
Depending on pump model, the motor has either
built-in, automatic, resetting of thermal
protection or is impedance protected and in
either case does not require additional external
protection. The temperature of the windings will
never exceed allowable limits, even if the rotor is
locked.
Wire sizes should be based on the ampacity
(current-carrying properties of a conductor) as
required by the latest edition of the National
Electrical Code or local regulations.
Both the power and grounding wires must be
suitable for at least 194 °F (90 °C).
If rigid conduit is to be used, the hub must be
connected to the conduit system before it is
connected to the terminal box of the pump.

5.1 For all 115 V and 230 V models
5.1.1 Single-speed pump wiring
1. Connect the white/white electrical leads from
the circulator pump to the incoming power
leads with wire nuts or other approved
connectors.
2. Attach incoming grounding wire to either of
the green grounding screws.
Fig. 3 Wiring diagram for all 115 V and
230 V single-speed pumps.
5.1.2 Multi-speed pump wiring
1. Insert black conductor into terminal "L"
position.
2. Insert white conductor into terminal "N"
position.
3. Insert grounding conductor into terminal
" " position.

6. Startup
Do not use the pump to vent the
system.
Do not start the pump before filling
the system.
Never let the pump run dry.
