Grundfos UP 15 series Manual

NOTE: UPS15-42 does not require manual turning of shaft.
Pump Mounting: For Indoor Use
Arrows on the side or bottom of the pump housing 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 recommend that isolation 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.
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 2B
is achieved.
6. (Closed System) Install a safety relief valve to protect
against temperature and pressure build-up.
7. If there are excessive suspended particles in the water,
it is recommended that a strainer and/or filter be
installed and cleaned regularly.
8. DO NOT START THE PUMP UNTIL THE SYSTEM
HAS BEEN FILLED AND CHECKED FOR LEAKS OR
OTHER POSSIBLE COMPONENT FAILURES.
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 line cord is unplugged and close
the isolation valves before removing the Allen screws.
To change terminal box position:
1. Remove the four (4) Allen screws from the pump
housing and stator (4 or 5mm wrench) while supporting
the stator (motor).
2. Carefully separate the stator from the pump housing
and rotate it to the correct terminal box orientation and
reseat it.
3. Replace the Allen screws and tighten diagonally and
evenly (7 ft.-lb. torque).
4. Check that the motor shaft turns freely. Remove the
large screw in the middle of the nameplate, insert a
small flat blade screwdriver into the end of the shaft,
and turn gently (see fig. 7a).
If the shaft does not turn easily, repeat the disassembly/
reassembly process.
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.
1. Shipment Inspection
2. Pre-Installation 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 UP 15 series pumps 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
psi 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 fluids.
System Applications: UP15 series pumps with
stainless steel or bronze volutes can be used in both
open and closed systems.
2. MaximumWaterTemperature:
UP15 pump with line cord only. The maximum allowable
water temperature is determined by the ambient or
surrounding air temperature as shown in Table 2A.
Table 2A – Maximum Water Temperature
Ambient (°F) 95 130 140 160 175
Water (°F) 230 220 210 190 175
Although the pump is designed to operate at maximum
water temperature of 230°F, it is recommended to
keep the operating temperature as low as possible (i.e.
below 140°F to avoid precipitation of calcium).
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.
Table 2B – Inlet Pressure Requirements
Water (°F) 190 165 140
Required Inlet Pressure (ft.) 5 4.5 3
(psi) 2.2 1.9 1.3
In a pressurized system, the required inlet pressure is the
minimum allowable system pressure.
In an open system, 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. Electrical
SAFE WARNING
Warning - Risk of electrical shock - This pump is supplied
with a grounding conductor. To reduce the risk of electric
shock, be certain that it is connected only to a properly
grounded grounding type receptacle.
The safe operation of this pump requires that it be grounded
in accordance with the National Electrical Code and local
governing codes and regulations.
Electrical Requirements
The operating voltage and other electrical data are marked
on the motor label. Make sure that the motor is suitable for
the electrical supply on which it will be used.
Electrical Connection
Insert the 115V plug on the line cord from the pump into a
properly grounded 115V outlet as shown in Figure 4a.
5. TimerTechnical Data
TIMER CONTROL
Supply Voltage: 115-120 VAC, 60 hertz
Contact Rating: 16 amps
Ambient Temperature: -4°F to 175°F
Shortest Switching Interval: 15 minute increment
Switch Modes: “Timer”, “ON” Override,

perature: 150°F
6. TimerTechnical Application
The Grundfos timer control is designed only for use with
specified Grundfos Series UP circulators installed in in-
door hot water service systems.
The timer control is designed to turn the circulator on and
off at preset times, allowing the user to select operation of
the circulator during high use periods of the day.

Setting and Operating the Timer Control
and Starting the Pump
NOTE: Before the circulator is started, the system must
be filled with liquid and vented.
1. Set the timer switch to the actual time by turning the
programming ring in the direction of the arrow until
the timing arrow points to the actual time on the ring.
2. Switch on the power supply to the circulator and set
the manual switch to the “ON” position. The circula-
tor will now start.
3. Set the required “ON”/”OFF” times on the program-
ming ring by pushing the programming tabs either
away from or toward the center of the ring. Tabs
pushed away from the center indicate the circulator
is switched ”ON” while tabs pushed toward the cen-
ter indicate the circulator is switched “OFF”.
4. Set the manual switch to the “TIMER” position. The
circulator will now start/stop according to the settings
of the programming tabs.
8. Failure to Operate
When the pump is first started, the shaft may rotate slowly
until water has fully penetrated the bearings. If the pump
does not run, the shaft can be rotated manually. To
accomplish this, switch off the electrical supply, and close
the isolation valves on each side of the pump. Remove
the indicator plug in the middle of the nameplate. Insert
a small flat blade screwdriver into the end of the shaft,
and gently turn until the shaft moves freely (see Figure
7a). Replace and tighten the plug. Open the isolation
valves and wait 2 to 3 minutes for the system pressure
to equalize before starting the pump.
5. For continuous operation, set the manual switch to
the “ON” position. To switch the circulator off, set the
manual switch to the “OFF” position.The “ON”/”OFF”
modes may be used without affecting the function of
either the programming ring or the timer switch.
6. In case of power outage the timer will not keep time.
After power has been restored, the correct time of
day must be reset by rotating the programming ring
in the direction of the arrow until the timing arrow
points to the actual time on the ring.
