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 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 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.
