4. Installation requirements
4.1 Location
The product can be installed both indoors and outdoors.
Please observe the following:
• Install the product to enable easy inspection, maintenance, and
service.
• We recommend that you place the product as close as possible
to the liquid to be pumped.
• We recommend that you install the product near a drain or in a
drip tray connected to a drain in order to lead away possible
condensation from cold surfaces.
4.1.1
Installation of the product in a frosty environment
Protect the product from freezing if it is to be installed outdoors
where frost may occur.
4.1.2
Minimum space
The pump requires a minimum space of 495 x 225 x 340 mm (19.5
x 8.9 x 13.4 inches).
Even though the pump does not require much space, we
recommend that you leave enough space for service and
maintenance access.
4.2
Maximum system pressure
Make sure that the system in which the pump is installed
is designed for the maximum pump pressure
The maximum inlet pressure depends on the head at the actual
duty point. The sum of the inlet pressure and the head must not
exceed the maximum system pressure.
We recommend installing a pressure-relief valve to protect the
pump so that the outlet pressure does not exceed the maximum
system pressure.
