BRUTEII
Model UP15-42F
Maintenance-Free
Circulators
1. Shipment Inspection
Examine the components carefully to make sure no
damage has occurred to the pump during shipment. Care
should be taken to ensure the pump is NOT dropped or
mishandled; dropping will damage the pump.
2.
Pre-lnstallation
Checklist
Before beginning
Installation
procedures,
the
following checks should be made. They are all
important for proper installation of the circulator
pump.
1. Uses:
Model UP15-42F pumps have cast iron volutes and are
recommended for closed hydronic systems (i.e.; airless,
non-potable water). They are designed to circulate water
from 50°F to 230°F up to a maximum pressure of 145
psi. 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 the
higher viscosity of the solution as compared to water.
Check with the manufacturer for information regarding
the suitability of pumping other fluids.
2. Maximum
Water Temperature:
The maximum allowable water temperature is determined
by the ambient or surrounding air temperature as shown
in Table 2A.

3. Inlet Pressure Requirements
The amount of pressure required at the inlet of the pump
is a function of the temperature of the water as shown in
Table 2B.

In a closed, pressurized system, the required inlet
pressure is the minimum allowable system pressure.
3.
Installation
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 Figure 3A).
If the terminal box position needs to be changed, it is
best to do so before installation. However, if the pump is
already installed, ensure that the electrical supply is
turned off and close the isolation valves before removing
the Allen screws.
To change terminal box position:
1. Remove the four (4) Allen screws (4mm) while
supporting the stator (motor),
2. Carefully separate the stator from the pump chamber
and rotate it to the correct terminal box orientation.
3. Replace the Allen screws and tighten diagonally and
evenly (7 ft.-lb, torque).
4. Check that the impeller turns freely. If the impeller
does not turn easily, repeat the disassembly/
reassembly process.
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. Install a safety relief valve to protect against
temperature and pressure build-up.
6. If there are excassive suspended particles in the water,
it is recommended that a strainer and/or filter be
installed on the inlet side of the pump and cleaned
regularly.
Pump Mounting:
For Indoor Use
Arrows on the side of the pump volute indicate direction
of flow through the pump. Grundfos circulators 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 Figure 3B).
It is recommended that isolation valves be installed on
each side of the pump. If possible, do not install elbows,
branch tees, or other flow-changing fittings just before or
after the pump. Provide support to the pump or adjacent
plumbing to reduce thermal and mechanical stress on
the pump.
Electrical
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:
The safe operation of this pump requires that it be
grounded in accordance with the National Electrical
Code and local governing codes or regulations. The
ground wires should be copper conductor of at least the
! size ofthe circuitconductorsupplyingpower to the pump.
Minimum ground wire size is 14 AWG. Connect the
ground wire to the grounding point in the terminal box
and then to an acceptable ground. Do not ground to a
i gas supply line.
Page 3
The proper operating voltage and other electrical
information can be found on the nameplate attached to
the top of the motor. The motor is impedance protected
and does not require additional external protection. The
temperature of the windings will never exceed allowable
limits, even if the rotor is locked.
Wire size 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).
Wire the hot lead to terminal "L," neutral wire to terminal "IV,"and
ground to the grounding terminal. For 230 volt pumps, the two hot
leads should be to "L"and "IV"and the ground to the grounding
terminal.

Start-Up
Do not start the pump until the system has been filled.
Completely vent the system prior to starting the pump,
Never operate the pump dry.
4.
Operation
GRUNDFOS domestic circulator pumps, installed properly
and sized for correct performance, will operate quietly
and efficiently and provide years of service.
Under no circumstances should the pump be operated
without water circulation or without the minimum required
inlet pressure for prolonged periods of time. This could
result in motor and pump damage.
