Installation & operating instructions

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-installation checklist
Before beginning installationprocedures, the following
checks should be made. They are all important for
proper installation of the circulator pump.
1. Uses:
Model UP(S) 15 series pumps are designed to
circulate water from 36°F to 230°F (UPS 15-35 from
36°F to 165°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 uids.
System applications: UP(S)15 series pumps with
stainless steel or bronze volutes can be used in both
open and closed systems.
2. Maximum water temperature:
UP(S)15 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 recom-
mended to keep the operating temperature as low
as possible (i.e. below 140°F to avoid precipitation
of calcium).
Note: UP15(S) pump with timer control
maximum water temperature: 150°F
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.).
3. Pump 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.
Figure 3A
Recommended Terminal Box Orientation
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 at blade
screwdriver into the end of the shaft, and turn
gently (see g. 7a).
If the shaft does not turn easily, repeat the
disassembly/reassembly process.

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.
GRUNDFOScirculatorscanbeinstalled 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.

Acceptable Unacceptable
It is recommend that isolation valves be installed
on each side of the pump. If possible, do not install
elbows, branch tees, and similar ttings 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 ush 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 ooded with water. Ensure that the static
head requirementfrom 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 lter be installed and cleaned regularly.
8. DO NOT START THE PUMP UNTILTHE SYSTEM
HAS BEEN FILLEDAND CHECKEDFOR LEAKS OR
OTHER POSSIBLE COMPONENT FAILURES.

4. Electrical
CAUTION: Do not energize pump until
properly installed
Warning - Risk of electrical shock - This pump is
suppliedwitha grounding conductor.To reduce the risk
of electric shock, be certain that it is connected only to
a properly grounded grounding type receptacle. The
safeoperationofthis pump requires thatitbegrounded
in accordance with the National Electrical Code and
local governing codes and regulations.

TIMER CONTROL
Supply Voltage: 115-120 VAC, 60 hertz
Contact Rating: 16 amps
Ambient Temperature: -4°F to 175°F
Max Fluid Temperature: 150°F
Shortest Switching Interval: 15 minute increment

moisture protection of the clock face.
6. Timer technical application
The Grundfos timer control is designed only for use
with specied Grundfos Series UP circulators installed
in indoor 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
PROGRAMMING RING
TIMING ARROW
MANUAL SWITCH
PROGRAMMING TABS
NOTE: Before the circulator is started, the system
must be lled 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 circulator will now start.
3. Set the required “ON”/”OFF” times on the
programming 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 center indicate the
circulator is switched “OFF”.
Figure 6b
Figure 6a
4. Set the manual switch to the “TIMER” posi
tion. The circulator will now start/stop accord
ing to the settings of the programming tabs.

Figure 8a
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.
8. Changing speeds with timer option
• Disconnect line cord from
system power.
• Remove (2) timer cover
screws.
• Gently rotate speed
selection stim to desired
speed (see Figure 7a).
• Re-install (2) timer cover
screws.
9. Troubleshooting
When the pump is rst 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
thepump. Remove the large screwin the middleof the
nameplate. Insert a small at blade screwdriver into the
end of the shaft, and gently turn until the shaft moves
freely (see Figure 8a). Replace and tighten the plug.
Opentheisolationvalves and wait 2to3minutesfor the
system pressure to equalize before starting the pump.
