Armstrong BPA S2 Manual De Instalación página 40

The motor shaft must be level on the horizontal axis.
Flow direction
The flow switch must be
installed in the discharge of the
pressurizing pump and must
follow the same direction of
the arrow printed in the pump
cabinet.
All pressurizing pumps have
an external flow switch which
allows greater flexibility in case of maintenance, repair or
failure.
Always make the electrical connections with the pressurizing
pump disconnected from the electrical force.
Do not disassemble the flow sensor for the installation of the
pressurizing pump as it is calibrated from the factory.
To protect the pump from solids or particles that could damage
the engine or impeller, it is recommended to have
a mesh strainer/water filter (not included) located
before the suction side of the pressurizing pump.
This filter must be kept clean so that the pump has
the minimum pressure required for its operation.
