INSTALLATION
Physical Installation
1. Mount the package to a level foundation of suitable mass and rigidity using 0.50” bolts.
• Consult a building professional.
2. Attach the discharge end cap to the opposite side of the discharge header from
the incoming site water connection using one of the provided couplings.
3. Attach the suction end cap to the opposite side of the suction header using the
other coupling.
4. Make piping connections for the site water.
• The suction and discharge can be connected to either end of the manifolds.
5. Install isolation valves near both the inlet and outlet of the packaged assembly.
• These valves aid with startup loads and prevent full discharge draining during
maintenance.
6. Install an appropriately sized pressure relief valve on the discharge side of the
pump.
7. Refer to the VFD Owner’s Manual for setup instructions.
Risk of severe injury or death.
• When lifting or moving heavy components, use suitable lifting equipment, in good condition, rated
for at least 5 times the weight of the materials being moved.
Risk of bodily injury or property damage.
• Pumps can develop very high pressure in some situations. Always install a pressure relief valve able
to pass the full pump flow.
• Install the pressure relief valve near the pressure tank and route to a drain capable of full system
flow.
• Ensure that the foundation is rated to accommodate the operating weight of the package and that it
is sized sufficiently for the weight and loads the package will experience.
• Do not over tighten piping connections on the fittings used to connect the site plumbing to each
header as this could damage the equipment and/or headers.

INSTALLATION
Electrical Connections
5
Electrical Connections
• Refer to the VFD Owner’s Manual and the VR Pump Owner’s Manual for proper wiring, installation and
electrical instructions, and hazards.
• The base booster pump package comes with pre-wired VFDs and an
electrical control panel.
• Provide power and ground wiring sized for the voltage, phase and
fuse size listed on the UL 508A labeled panel. Terminate the power
wiring on the panel's fused disconnect and land the ground wire on
the sub panels electrical stud.
HMI Digital Outputs Wiring
NOTE: Some packages come without an HMI and, therefore, do not need wiring to the VFD.
Risk of severe injury or death by electrical shock.
• To minimize risk of electrical shock, disconnect power before working on or around the system.
• Capacitors inside the drive can still hold lethal voltage even after power has been disconnected—
ALLOW 5 MINUTES FOR DANGEROUS INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING
COVER OR WORKING WITH INTERNAL COMPONENTS.
• Once site power has been provided to the control panel and those feeds are live, there will be ener-
gized electrical lines in the control panel up to the remote disconnect terminals even when the
panel's remote disconnect switch is off. Always de-energize the site power feeding the control panel
when opening the panel; otherwise, an electrical shock hazard will still exist which can cause serious
injury, death and major property damage.

DRIVE CONFIGURATION
Multi-Drive Configuration
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.
• The VFDs are configured to act as the central command structure for the package. One VFD is desig-
nated as the Master to provide cascade and speed control for all other VFD units.
• Master status can be switched between the VFDs by setting the correct parameter when the drive is in
Hand Mode and turned off.
• The package is configured to operate the pumps in a Lead/Lag fashion. Lead and lag roles are set by
the Master VFD.
• The lead pump designation will rotate so all VFDs will run about the same amount of time and not
exceed the hours set in the Pump Duty Switch Over Time parameter. Refer to “VFD Parameter Screens 1
& 2” on page 9 to modify this parameter with the Master VFD Control HMI Menu.
Pump Discharge Pressure Sensing
The pump discharge pressure is measured using one of the pressure transducers installed (per pump) and
wired into one of the analog inputs (AI). Refer to the VFD manual provided for the specific input terminal
number.
• For VFD discharge pressure sensing during operation, refer to “VFD Discharge Pressure Sensing”
on page 14.
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.
Pump Suction Pressure Sensing
To prevent pump damage during periods of abnormally low suction pressure, each pump circuit is equipped
with a Low Pressure Switch (LPS) on the inlet side to the pump(s). The LPS is normally open and closes
above 5 PSI.
• The switch is wired into the enable circuit on each VFD control terminal connection block (digital
input) to keep the string powered and the VFD enabled as long as the switch reads pressures
above 5 PSI.
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.

OPERATION
VFD Discharge Pressure Sensing
14
OPERATION
VFD Discharge Pressure Sensing
Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.
• The pump system maintains a set discharge pressure by comparing it to a user defined setpoint. Then
the system adjusts the speed of the pump motor VFDs to achieve that setpoint.
• During no flow periods, the VFDs will stop the pump motors and enter standby mode. The system will
stay in the ready state until the discharge pressure drops and water demand resumes. Refer to
“Standby Activation Speed” on page 15.
• The lead pump will be the first pump dispatched to meet the pressure setpoint established in the VFD.
• The pump motor speed will be bounded by the minimum and maximum speed settings established in
VFD parameters the speed driven by the PID control algorithm in the VFD.
Assist Pump Speed Parameters
Three factory preset VFD parameters control the speed at which additional assist pumps are activated or
deactivated to aid the lead pump. Refer to the VFD Owner’s Manual for additional details as setup instruc-
tions will vary. Within the Master VFD Control HMI they are:
1. Assist Pump Settling Time: the wait period, in seconds, before assist pumps are activated or deacti-
vated.
2. Assist Pump Start Speed: the maximum speed the lead pump will run without more assistance before
the Assist Pump Settling Time is reached.
• If the lead pump is operated above the Assist Pump Start Speed for a period of time exceeding the
Pump Settling Time, the Master VFD will start a lag pump and drive both at the same speed.
• In Triplex and Quad packages, additional pumps will be activated to assist if needed.
3. Assist Stop Speed: the minimum speed at which the assist pumps will run before the Assist Pump Set-
tling Time is reached.
• Once the pumps operate at a speed lower than the Assist Pump Stop Speed for a period of time
exceeding the Pump Settling Time, assist pumps are deactivated one at a time.
• This parameter may be adjusted to have the assist pumps stay on longer or shut down sooner.
NOTE: Assist Stop Speed should be higher than the Standby Activation Speed setting. Refer to
“Standby Activation Speed” on page 15.
All three parameters can be viewed or modified in the VFD Parameter Screen 2 of the Master VFD Control
HMI. When setting the parameters, be sure to consider pump efficiency curves, pump operating ranges, and
any constraints to minimize pump run times. Refer to “VFD Parameter Screens 1 & 2” on page 9.
Refer to the VFD Owner’s Manual for setting the speed parameters individually.

OPERATION
Standby Activation Speed
15
Standby Activation Speed
The Standby Activation Speed is the speed representing a no flow condition of the pump preset at the fac-
tory. It can be determined by dead heading the lead pump and recording the pump speed. Refer to the VFD
Owner’s Manual for additional details as setup instructions will vary. The parameter can be updated in the
VFD Parameter Screen 2 of the Master VFD Control HMI. Refer to “VFD Parameter Screens 1 & 2” on page 9.
NOTE: Programming a Standby Activation Speed of 1-3 HZ above the value has the VFD go into
standby mode during no flow periods.
When the lead pump motor is operated at a speed lower than the Standby Activation Speed for a period of
time exceeding the Standby Mode Timer, the lead pump is taken off-line and placed in a standby status. The
lead pump will remain in standby until the Master VFD measures a pressure less setpoint minus the PID
Restart Error Level.
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.
• To set the Standby Mode Timer or the PID Restart Error Level via the Master VFD Control HMI, refer
to “VFD Parameter Screens 1 & 2” on page 9.
Boost Function
A boost function can be enabled so that the lead pump will run at a higher speed for a period of time before
going into standby mode. This can be set up by programming a boost Speed Time for a value greater than 0
(this value is the seconds the boost will operate at) and setting the boost speed in the Preset Speed.
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary.
• To activate the boost feature via the Master VFD Control HMI Menu, refer to “Master VFD Control
HMI Main Screen” on page 8.
VFD PID Setpoint Pressure
• The VFD PID reference parameter represents the pressure transducer range.
• The setpoint pressure is calculated internally by the VFD by dividing Pressure Setpoint by Pressure
Transducer Range. Refer to “VFD Parameter Screens 1 & 2” on page 9 to change these parameters via
the Master VFD Control HMI Menu.
• Refer to the VFD Owner’s Manual for additional details as setup instructions will vary for individual
drives.
• If a replacement drive is installed without this function block programming, the discharge pressure set-
point will need to be manually entered in the VFD. Refer to the owner’s manual for instructions.
Pre-Start Verifications
1. Check electrical incoming voltage meets requirements and an adequate ground connection exists.
2. Inspect the overall system for damage during installation.
3. Pressurize the system with the site water to remove any trapped air.
4. If there are any water leaks in the piping, isolate the location and tighten the connections.
• If the leaks are at the threaded connections in the piping circuits, tighten each fitting so the suction
and discharge manifolds equally distanced.

DESCRIPCIÓN DEL PRODUCTO
Descripción
VR SpecPAK incluye dos, tres o cuatro bombas VR controladas por variadores de fre-
cuencia independientes, como los variadores de frecuencia Q-Link, el variador Inver-
tek o el Cerus X-Drive.
Las bombas verticales de etapas múltiples serie VR se encuentran disponibles en
opciones de 3 a 30 m3/h (16 a 160 GPM) en el punto de máxima eficiencia con todas
las piezas hidráulicas internas de acero inoxidable 316 para brindar una durabilidad,
eficiencia y rendimiento superiores. Su tamaño pequeño, motor de primera calidad y
componentes resistentes garantizan una larga vida útil que ofrece una solución de
bombeo de agua en casi cualquier aplicación complicada. Las bombas son aptas
para el suministro de agua y los sistemas de elevación de presión, riego y agricul-
tura, el tratamiento de agua y las aplicaciones de climatización. Para obtener más
información y ayuda durante la instalación o el mantenimiento, consulte el manual
del propietario de la bomba VR que se incluye.
Los variadores de frecuencia (VFD, por sus siglas en inglés) dentro del paquete están
diseñados para controlar y proteger los motores de la bomba. Para obtener más
información y ayuda durante la instalación o el mantenimiento, consulte el manual
del propietario del VFD que se incluye.
Es posible que el paquete venga con una pantalla HMI (interacción persona/
máquina) opcional de control del VFD principal. Con esta pantalla de control, el
usuario puede actualizar los parámetros de cada VFD individual, lo que facilita el
control de las bombas en paquete en vez individualmente. Los parámetros incluyen velocidad de rampa de aceleración y desacele-
ración; información del PID; velocidad del VFD; valor de presión establecido; rango del transductor de presión; cambio de servicio
de la bomba con el tiempo; velocidad de activación en espera y temporizador de modo; velocidad de arranque, parada y estabiliza-
ción de la bomba de asistencia; y diferencial de reactivación.
Los componentes del paquete en conjunto no tienen la misma garantía. Para obtener información sobre la garantía, consulte el
manual del propietario de cada componente.

INSTALACIÓN
Instalación física
1. Monte el paquete en una base nivelada de masa y rigidez adecuadas usando pernos de 12.7 mm (0.50 pulg.)
• Consulte a un profesional de la construcción.
2. Coloque el tapón del extremo de descarga en el lado opuesto del cabezal de
descarga de la conexión de agua entrante del sitio utilizando uno de los acoples
provistos.
3. Coloque el tapón del extremo de succión en el lado opuesto del cabezal de suc-
ción utilizando el otro acople.
4. Realice las conexiones de las tuberías para el agua del sitio.
• La succión y la descarga se pueden conectar a cualquier extremo de los
múltiples.
5. Instale válvulas de aislamiento cerca de la entrada y la salida del conjunto
empaquetado.
• Estas válvulas ayudan con las cargas de arranque y evitan el drenaje com-
pleto de la descarga durante el mantenimiento.
6. Instale una válvula de alivio de presión de tamaño adecuado en el lado de des-
carga de la bomba.
7. Consulte el manual del propietario del VFD para obtener instrucciones sobre
ajustes.
Riesgo de muerte o lesiones graves.
• Cuando levante o mueva componentes pesados, use equipo de elevación adecuado, en buenas con-
diciones, clasificado para un mínimo de cinco veces el peso de los materiales a mover.
Riesgo de lesiones corporales o daños materiales.
• En algunas situaciones, las bombas pueden generar una presión muy alta. Siempre instale una vál-
vula de alivio de presión que pueda permitir el paso del flujo total de la bomba.
• Instale la válvula de alivio de presión cerca del tanque de presión y dirijala a un desagüe capaz de
flujo completo del sistema.
• Asegúrese de que la base esté clasificada para acomodar el peso de funcionamiento del paquete y
que tenga el tamaño suficiente para el peso y las cargas a las que será sometido el paquete.
• No ajuste excesivamente las conexiones de tuberías en los accesorios utilizados para conectar la plo-
mería del sitio a cada cabezal, ya que esto podría dañar el equipo o los cabezales.
