3. Installation procedures

Warning!
Never make any connections in
the pump terminal box unless the
electrical supply has been
switched off.
The pump should not be
connected to the electrical
system until it has been properly
installed in the piping system.
Risk of electrical shock — this
pump has not been investigated
Caution
for use in swimming pool or
marine areas.

3.1 Piping considerations

When making piping connections, be sure
to follow the piping manufacturer's
recommendations and all code requirements
for piping material.
Thoroughly clean and flush all dirt and
sediment from the system before attempting to
install the pump.

3.1.1 Location in the piping line

The pump should never be located at the
lowest point of the piping system (where dirt
and sediment collect), nor should it be located
at the highest point of the piping system
(where air accumulates).
Warning!
The pump must be positioned
so that someone cannot
accidentally come into contact
with the hot surfaces of the pump.
When installing the pump into the piping
system, Grundfos recommends that pressure
gauges be installed in the inlet and discharge
flanges or pipes. This will allow the pump and
system performance to be checked.
Do not block the pipe plugs in the pump
housing flanges by locating the terminal box
over these plugs.

3.1.2 Mounting positions

The arrows on the pump housing indicate the
direction of water flow. The XL UP/UPS pump
may be installed in vertical or horizontal
piping, but the motor shaft must always
remain horizontal, as shown in fig. 1.

Installation positions
3.1.3 Terminal box position
At the bottom of the stator, closest to the pump
housing, there are three drain holes to allow
condensed water to escape. The drain holes
shall not be blocked for any reason and one
drain hole must always point downward.
There is not a drain hole directly below the
terminal box; therefore the terminal box must
be positioned in one of the positions shown in
fig. 1 or fig. 2.
3.2 Changing the terminal box
position
Warning!
Before starting any work on this
circulator, be sure electrical
supply has been switched off
and it cannot be accidentally
switched on.
If the pump is already installed in the system,
the system must be drained or the isolation
valves on both sides of the pump must be
closed and the pressure released/relieved by
removing the vent plug.
Exercise caution when draining
the system or removing the vent
plug as the fluid in the system
Caution
may be scalding hot and under
pressure.
Only after the pressure has been relieved and
the pump drained should you proceed with the
next steps.
