maintain a device's clean integrity, this service should be performed by the
factory or one of the certified service centers.
2-7 Gas Connections
Prior to installation, ensure that all piping is clean and free from
obstructions. Install piping in such a manner that permits easy access to
the device if removal becomes necessary.
2-8 In-Line Filter
It is recommended that an in-line filter be installed upstream from the device
to prevent the possibility of any foreign material entering the flow sensor or
control valve. The filtering element should be replaced periodically or
ultrasonically cleaned.
2-9 Mechanical Installation
The recommended installation procedure guidelines are as follows:
• The device should be located in a clean, dry atmosphere relatively free
from shock and vibration.
• Leave sufficient room for access to the user interface and MAC
ID and baud rate switches (if equipped) at the top of the device.
• Install the device in such a manner that permits easy purge and removal
if the device requires servicing.
The GF40/GF80 Series also utilizes MultiFlo ® technology that allows the
user to configure standard configurations ("SAs") or "blanks" for a variety of
pure gases and mixtures. As a result, MultiFlo
® technology enables the user
to reduce unique inventory requirements.
