5700512-C Installation and Operation 3-3
Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs
Confirming the MFC Model
Before you install the MFC, ensure that you have the correct model for your system
requirements. The part number, serial number, calibration gas, and full-scale flow are
listed on the label of the MFC. See “Product Label” on page 6-40 for an example
MFC label.
Preparing the Installation Site
Before installing the MFC, thoroughly clean, dry, and purge all piping associated with
the entire flow control system (in accordance with your company’s procedures). The
MFC control valve is not capable of completely shutting off gas flow. You must
install another shut off valve downstream of the MFC to completely stop gas flow.
Unpacking the MFC
Unpack and inspect the MFC carefully, looking for obvious physical damage. If no
damage is apparent, locate and save all documentation, and then proceed with the
installation procedures.
If you do see signs of shipping damage, contact Aera, an Advanced Energy company,
and the carrier immediately (see “AE Global Services” on page 5-6 for contact
information). Save the shipping container for submitting necessary claims to the
carrier.
Save any undamaged shipping materials in the event you must ship the MFC in the
future. For more information on shipping an MFC, see “Packing an MFC for
Shipping” on page 5-10.
Positioning the MFC
Position the MFC so the gas flow is in the direction of the arrow stamped on the MFC
base. The MFC can be mounted in any position, but the zero point may shift if the
MFC is mounted in a non-vertical position. Adjust the zero point in the intended
mounting position before running the MFC (see “Zeroing the MFC” on page 3-9 for
more information).
The MFC is manufactured in a cleanroom environment and delivered in
contamination-free packages. Unpack MFC products in a cleanroom.
