3. Receiving the product
3.1 Inspecting the product
On receipt of the product, do the following:
1. Check that the product is as ordered.
If the product is not as ordered, contact the
supplier.
2. Make sure that the supply voltage and frequency
correspond to the values stated on the product
nameplate.
3.2 Scope of delivery
The box contains the following items:
• 1 Grundfos SCALA1 pump
• 1 quick guide
• 1 safety instructions booklet.
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.
5. Mechanical installation
WARNING
Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product. Make
sure that the power supply cannot be
switched on accidentally.
WARNING
Electric shock
Death or serious personal injury
‐Mount the product horizontally to avoid
condensation in the electrical insulation
inside the control box.
WARNING
Chemical hazard
Death or serious personal injury
‐Before the pump is used for supplying
drinking water, flush the pump
thoroughly with clean water.

English (GB)

WARNING
Biological hazard
Death or serious personal injury
‐Before the pump is used for supplying
drinking water, flush the pump
thoroughly with clean water.
5.1 Positioning and mounting the product
Always place the product in a horizontal
position. A higher inclination can cause
electric shock due to condensation in the
electrical insulation inside the control box.
1. Place the product in a horizontal position with a
maximum inclination angle of ± 5 °. The base
plate must face downwards.
2. Fasten the product to a solid horizontal
foundation by means of screws through the holes
in the base plate.

5.2 Connecting the pipe system
Make sure that the pump is not stressed
by the pipe system.
Always loosen and tighten the union nuts
on the inlet and outlet ports by hand.
Damage to the inlet and outlet parts
increases the risk of leakage.
We recommend that you install isolating
valves on the inlet and outlet side of the
pump.
1. Turn the union nuts by hand to loosen the inlet
and outlet ports.
2. Seal the pipe fittings with thread sealing tape.
3. Carefully screw the inlet and outlet connections
onto pipe fittings using a pipe wrench or a similar
tool. Keep the union nut on the pipe fitting if you
have removed it from the pump. The pump is
equipped with flexible connections, ± 5 °, to
facilitate the connection of inlet and outlet pipes.
4. Fasten the connections to the inlet and outlet
ports by holding the connection with one hand
and tightening the union nut with the other hand.

5.2.1 Inlet and outlet pipes
Follow these general precautions when connecting
the inlet and outlet pipes.
Do not let the pump support the pipes. Use
pipe hangers or other supports at proper
intervals to provide pipe support near the
pump.
The internal diameter of the pipes must
never be smaller than the diameter of the
pump ports.
• Install the pipes so that air pockets are avoided,
especially on the inlet side of the pump.
• Use eccentric reducers with the tapered side
down.
• Make sure the pipes are as straight as possible
to avoid unnecessary bends and fittings. We
recommend long-radius 90 ° pipe bends to
decrease friction loss.
• Run the inlet pipe as direct as possible and,
ideally, make sure that the length is at least ten
times the pipe diameter.
• If possible, run a horizontal inlet line. We
recommend a gradual upward slope for pumps
operating in suction-lift conditions.
• A short pipe must be of the same diameter as the
inlet port or larger.
• A long pipe must be one or two sizes larger than
the inlet port, depending on the length.

5.2.2 Maximum tapping point
We recommend that you install the unit so that the
height between the unit and the highest tapping point
does not exceed the values shown in the table
below.
