2. Receiving the product
2.1 Inspecting the product
Check that the product received is in accordance with the order.
Check that the voltage and frequency of the product match the
voltage and frequency of the installation site. See section
2.2 Scope of delivery
The box contains the following items:
• 1 Grundfos SCALA2 pump
• 1 quick guide
• 1 safety instructions booklet.
3. Installing the product
3.1 Location
The pump can be installed indoors or outdoors, but it must not be
exposed to frost.
We recommend that you install the pump near a drain or in a drip
tray connected to a drain in order to lead away possible
condensation from cold surfaces.
3.1.1 Minimum space
The pump requires a minimum space of 430 x 215 x 325 mm (17
x 8.5 x 12.8 inches).
Even though the pump does not require much space, we
recommend that you leave enough space for service and
maintenance access.
3.1.2 Installing the product in frosty environment
Protect the pump from freezing if it is to be installed outdoors
where frost may occur.
3.2 System sizing
The pump is factory-set to 3 bar (44 psi) outlet pressure which
can be adjusted according to the system in which it is
incorporated.
The tank precharge pressure is 1.25 bar (18 psi).
In case of suction lift of more than six metres, the pipe resistance
on the outlet side must be at least two metres water column or 3
psi at any given flow in order to obtain optimum operation.
3.3 Mechanical installation
3.3.1 Positioning the product
Always mount the pump on the base plate in a horizontal position
with a maximum inclination angle of ± 5 °.
3.3.2 Foundation
Fasten the pump to a solid horizontal foundation by means of
screws through the holes in the base plate. See figs
and

Observe these instructions for explosion-proof
products.
A blue or grey circle with a white graphical symbol
indicates that an action must be taken.
A red or grey circle with a diagonal bar, possibly with
a black graphical symbol, indicates that an action
must not be taken or must be stopped.
If these instructions are not observed, it may result in
malfunction or damage to the equipment.
Tips and advice that make the work easier.
Install the pump in such a way that no undesirable
collateral damage can arise due to leakage.
If the unlikely event of an internal leakage occurs, the
liquid will be drained through the bottom of the pump.
Make sure that the system in which the pump is
incorporated is designed for the maximum pump
pressure.
DANGER
