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.
