VORTEX AND

ACCUFLOW™ HP+

INSTALLATION

The following sections are included to illustrate the proper procedure for mounting and plumbing the AccuFlow

system.

This section assumes that the Raven control console has already been installed and all installation and safety

procedures have been completed or understood.

NOTE:

In addition to the Raven control console and associated cabling, a speed sensor and flow cabling

must also be installed with the Raven AccuFlow system. Refer to

Testing the Speed Sensor Extension

Cable

section on page 77 for examples of AccuFlow systems and cable connections. Contact a local

Raven dealer for more information and assistance.

When installing hoses, cables, and wires always take care that they cannot be pinched, cut, or otherwise damaged

during normal operation.
