DANGER
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 beswitched on accidentally.

Make sure that the system in which thepump is incorporated is designed for the
maximum pump pressure.
The pump is factory-set to 3 bar (44 psi) outletpressure which can be adjusted according to thesystem in which it is incorporated.
The tank precharge pressure is 1.8 bar (26 psi).
In case of suction lift of more than 6 metres (19.7 ft),the pipe resistance on the outlet side must be at least
2 metres water column or 3 psi at any given flow inorder to obtain optimum operation.
4.2.1 Maximum system pressure
Make sure that the system in which thepump is installed is designed for the
maximum pump pressure.

5.1 Positioning the product
Always mount the pump on the base plate in ahorizontal position with a maximum inclination angleof ± 5°.

5.2 Foundation
Fasten the pump to a solid horizontal foundation bymeans of screws through the holes in the base plate.
See the figures below.

Horizontal foundation

BC

The maximum inlet pressure must not exceed 6 bar,and the maximum system pressure must not exceed
10 bar.
We recommend installing a pressure-relief valve toprotect the pump so that the outlet pressure does notexceed the maximum system pressure.

TM086089

When using SCALA2 in installations withwater heaters, you must use a non-return
valve, pressure-relief valve or a thermal
expansion tank between SCALA2 and thewater heater. This prevents the backflow
pressure from exceeding the 10 bar
pressure limit the pump is designed for.

Hold the connection with one hand and tighten theunion nut with the other hand.

Make sure that the pump is not stressedby the pipe system.

5.4 Condensation

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.

TM085891

1. Turn the union nuts by hand to loosen the inlet
and outlet ports. See the figure below.

2. Seal the pipe fittings with thread sealing tape.
If the pipe is sealed with flat gaskets,
do not use sealing tape.

Do not use packing yarn when
installing the product.
3. Carefully screw the inlet and outlet connections to
the pipe fittings using a pipe wrench or similar
tool. Keep the union nut on the pipe fitting if you
have removed it from the pump. The pump isequipped with flexible connections, ± 5°, tofacilitate the connection of inlet and outlet pipes.
See the figure below.

English (GB)

5.3 Connecting the pipe system

10

When SCALA2 is installed in a warm room and ispumping cold water, there is a risk of condensation
forming on the pump and associated components.
We recommend that you place the product on a drip
tray and install it in a room with a drain. This
precaution is essential to prevent potential damage tothe surroundings and to ensure safe and efficient
operation of the product.
• Drip tray: Placing the product on a drip tray helps
contain any minor leakages or spills that may
occur during operation. This can prevent waterfrom coming into contact with the floor, which
could cause personal injury or damage to the
product.
• Room with a drain: Installing the product in aroom with a drain serves as an additional safetymeasure. In the event of a significant leakage or
malfunction, the drain carries away excess wateror liquids, reducing the risk of flooding or water
damage.

We recommend using flexible hoses andmounting the pump on a vibration-damping
rubber pad.
Vibrations from the pump may be transferred to thesurrounding structure and create noise in the 20-1000
Hz spectrum, also called the bass spectrum.
Correct installation using a vibration-damping rubber
pad, flexible hoses and correctly placed pipe hangers
for rigid pipes can reduce the noise experienced by
up to 50 %.
Place pipe hangers for the rigid pipes close to theconnection of the flexible hose.

The pump may produce a clicking noise if there ispositive pressure at the inlet of the pump. In thiscase, you can mount a locking pin to avoid this noise.
When a locking pin is mounted, the self-priming
function is not applicable.
If the pump has a negative pressure at the inlet,
removing the locking pin is necessary to enable theself-priming function.

H1

When using SCALA2 in installations with water
heaters, you must use a non-return valve, pressurerelief valve or a thermal expansion tank between
SCALA2 and the water heater. This prevents the
backflow pressure from exceeding the 10 bar
pressure limit the pump is designed for.
When water is heated in a closed-loop system, its
volume increases. A thermal expansion tank is mostoften used to absorb the additional volume created bythis process. The small reservoir inside SCALA2 isbuilt to prevent cycling and cannot compensate forthermal expansion.
Always consult the applicable water heater
manufacturer specifications as installations may vary.

7.3.1 Boosting from a well or a tank

The pump can be set to provide a water pressure
between 1.5 to 5.5 bar (22 to 80 psi) at intervals of
0.5 bar (7 psi).
The factory setting is 3 bar (44 psi).

If you are boosting from a well or a tank, make sure
not to set the pressure setpoint too high. The
difference between the inlet pressure and outletpressure must not exceed 3.5 bar (51 psi).

We recommend you to use the defaultpressure of 3.0 bar (44 psi) which will suit
most applications.

7.4 Shaft seal run-in
The shaft seal faces are lubricated by the pumped
liquid. A slight leakage from the shaft seal of up to 10
ml per day or 8 to 10 drops per hour may occur.
When the pump is started up for the first time, or
when the shaft seal has been replaced, a certain runin period is required before the leakage is reduced toan acceptable level. The time required for thisdepends on the operating conditions, that is, every
time the operating conditions change, a new run-in
period will be started.
Under normal conditions, the leaking liquid will
evaporate. As a result, no leakage will be detected.
If the unlikely event of an internal leakage occurs, theliquid will be drained through the bottom of the pump.
Install the pump in such a way that no undesirable
collateral damage can arise.

18

If the pump is to be stored for a period of time, forexample during the winter, drain it and store it indoors
in a dry location.
Temperature range during storing must be -40 to +70°C (-40 to +158 °F).

If the pump cannot reach the user-defined pressure
setpoint, the self-learning function automaticallyadjusts the setpoint. This process may take up to 5
minutes.
The pump lowers the setpoint to either 4.5, 3.5 or 2.5
bar (65, 51 or 36 psi).
The self-learned setpoint is indicated on the operating
panel by one flashing green light.
After every 24 hours, the pump automaticallyattempts to revert to the original user-defined
setpoint. If this is not possible, the pump again
returns to the self-learned setpoint. The pumpcontinues to operate with the self-learning setpoint
until the user-defined setpoint can be reached.
Example:The user-defined pressure is set to 5 bar (72 psi),
indicated by constant green lights on the pressure
indicator panel.
The pump is unable to reach this pressure due tonegative pressure on the inlet side.
The self-learning function automatically adjusts the
setpoint to 3.5 bar (51 psi), indicated by one flashinggreen light on the pressure indicator panel.
After 24 hours, the pump automatically tries to adjust
the setpoint back to 5 bar (72 psi).

Esta garantía limitada se proporciona únicamente para los productos de consumo vendidos en los Estados
Unidos y es aplicable a las transacciones de consumo tal y como se define en y resulta aplicable en virtud de laley de Garantías Magnusson-Moss y cualquier otra legislación federal y/o estatal aplicable. Para el caso deproductos que no sean de consumo, consulte los términos de la garantía de Grundfos definidos en la cláusula
10 de los términos y condiciones de venta de productos y servicios de Grundfos para los EE. UU., disponibles

no mayor a treinta (30) meses a partir de la fecha de fabricación que figura en la placa de datos del producto yen el empaque del mismo o el periodo mínimo exigido por la legislación estatal aplicable. Para Nueva Jersey, el
periodo aplicable es de un año a partir de la fecha de compra.
El periodo de garantía para los productos, partes y componentes de repuesto vence a los treinta (30) meses
contados a partir de la fecha de fabricación original del producto adquirido en primer lugar, a menos que lalegislación estatal aplicable exija un periodo más largo. Para Nueva Jersey, el periodo de garantía de los
productos, partes y componentes de repuesto vence un año contado a partir de la fecha original de compra delproducto, no de la fecha de sustitución.
Los productos vendidos por Grundfos que sean producidos por otros fabricantes no están cubiertos por estagarantía.
Tenga en cuenta que, al comprar un producto Grundfos en línea, es importante revisar la fecha defabricación y la duración de la garantía con el vendedor, ya que es posible que el producto ya no estécubierto por esta garantía limitada.
Cuando un producto esté sujeto a esta garantía limitada, el comprador deberá ponerse en contacto con
el vendedor al que haya comprado el producto para presentar una reclamación.
Si el vendedor de un producto ya no está en el negocio, el comprador debe ponerse en contacto con socio deservicio autorizado por Grundfos, que puede encontrar en la dirección www.grundfos.com/us, en la sección“Support” > “Contact Service”.
Como parte de la presentación de una reclamación, el comprador deberá devolver el producto descompuesto a
su costa, en la medida en la que lo permita la legislación aplicable, junto con el comprobante de compra y una
explicación del defecto, la fecha en que este se haya producido y las circunstancias en torno al defecto. En
Nueva Jersey no existe ninguna prohibición de devolver un producto descompuesto a costa del comprador. Si
la legislación estatal aplicable obliga a Grundfos a hacerse cargo de los gastos de envío, el comprador deberá
ponerse en contacto con un servicio técnico autorizado por Grundfos para organizar el envío. El comprador
también debe responder con prontitud a Grundfos cualquier consulta relacionada con una reclamación degarantía.
La responsabilidad de Grundfos hacia el comprador en virtud de esta garantía limitada se limita a lareparación o sustitución de un producto (a decisión de Grundfos), que es el único y exclusivo remedio
para el comprador en la medida permitida por la legislación aplicable. Para Nueva Jersey, esta limitación
resulta permisible.
Esta garantía no cubre lo siguiente: el desgaste ordinario; el uso de un producto para aplicaciones para las que
no está diseñado; el uso de un producto en un entorno inadecuado; las modificaciones, alteraciones oreparaciones realizadas por cualquier persona que no actúe con la autorización por escrito de Grundfos; elincumplimiento de las instrucciones, manuales de operación, cualquier otro lineamiento o las buenas prácticas
industriales de Grundfos; el uso de equipos auxiliares descompuestos o inadecuados en combinación con un
producto; el uso de repuestos o partes de sustitución no proporcionados ni autorizados por Grundfos; el daño
accidental o deliberado o el uso indebido de un producto.
El periodo para presentar una reclamación en virtud de la garantía implícita de comerciabilidad y la garantía
implícita de idoneidad se limita al mismo periodo previsto por esta garantía en la medida permitida por lalegislación aplicable. Para los residentes de Nueva Jersey, esta limitación resulta permisible, si bien se debe
tener en cuenta que algunos estados no permiten limitaciones en cuanto a la duración de una garantía implícita,
por lo que la limitación anterior puede no resultar aplicable en su caso.
Grundfos no será responsable de ningún daño indirecto o consecuente en relación con un producto en
la medida en la que lo permita la legislación aplicable. Para los residentes de Nueva Jersey, esta limitación
resulta permisible, si bien debe tenerse en cuenta que algunos estados no permiten limitaciones en cuanto adaños indirectos o consecuentes, por lo que la limitación anterior puede no resultar aplicable en su caso.
