5 Installation
5.1 Inspection and preparation
5.1.1 Location
The FLEX should be located to allow room for access, maintenance, and inspection with ample
headroom for lifting.
5.1.2 Protection of openings
USE PROTECTIVE COVERS ON FLEX PORTS WHEN NOT IN SERVICE
When the FLEX is shipped, all openings are covered. These protective coverings should not be
removed until installation. If for any reason a FLEX is removed from service, the protective covers
should be reinstalled.
5.1.3 Support
A mounting bracket should be provided to support the weight of the FLEX when it is installed.
The bracket should support the unit by the vessel body or vessel flange (not by the pipe
connections) and provide means (such as shims) to adjust the position of the unit to align with
system piping.
5.1.4 System piping
SYSTEM PIPING MUST BE CLEAN AND FREE OF ALL DIRT AND DEBRIS
System and header piping connected to FLEX units must be clean and free of all dirt, debris, and
foreign objects to avoid any contamination of the FLEX units that might cause damage to close
internal clearances and brittle ceramic components.
5.1.5 Free spinning rotor check
This free spinning rotor check is optional and should only be performed immediately prior to
installation or assembly of the device. This check can help ensure a successful start-up of the
device.
DO NOT INSERT HANDS OR FINGERS INSIDE THE DEVICE
Pinch points and sharp edges inside the device can result in injury and potential finger
amputation.
DO NOT INSERT METAL OBJECTS INSIDE THE DEVICE
Do not use any metal object to push internal ceramic parts, such as the rotor, as this may cause
cracking, chipping, or other damage to the parts, which may result in failure of the device.
