Requirements To The Installation Site - Bühler technologies AGF-FE-4 Guía Rápida

AGF-FE-4, AGF-FA-5
• When used with moist gasses, a condensate separator
must be installed. Moist gasses can clog pores in the filter.
Gas pressure building up can result in an impermissible
temperature rise.
• Observe the grade of filtration of the fine mesh filter and
if necessary install a pre-filtration to ensure larger solid
particles do not clog the filter prematurely.
• Observe the durability list in this document. Only use me-
dia compatible with the filter materials.
• Do not repair the filter. Damaged filter components must
be replaced.
Operation and Control
DANGER
Risk of explosive gasses leaking and crossing zones
Check the filter is tight prior to operation.
Inadequately sealed filters can leak. Gas may leak or the am-
bient atmosphere be drawn in. Use a suitable method for the
leakage test, appropriate for the application.
Operation with moisture detector (AGF-FA-5 only)
DANGER
Explosion hazard
To operate the filter in an explosive atmosphere with mois-
ture detector, the moisture detector and controller must be
ignition protection class intrinsically safe "i". The use of non-
intrinsically safe components may result in ignition in explos-
ive atmospheres.
Also note the specifications under EN 60079-14 in this respect.
4 Transport and storage
The device should be only transported in the original case or
in appropriate packing.
If the device is not used for some time, protect it against heat
and humidity. Store the device in a roofed, dry, and dust free
room. Temperature should be between –5 °C and 40 °C (23 °F
and 104 °F).
5 Installation and connection

5.1 Requirements to the installation site

The front plate has to be prepared according to the drawings
in the data sheets.
The filter should be installed in a way so the filter element can
be replaced. If the filter protrudes from a contour, please note
this poses a risk of damage.
The Maximum pressure is 2 bar (29 psi).
5.2 Connecting the gas lines
The connections must be made carefully and properly using
suitable fittings.
Please check if your version has G-threads or NPT threads. On
the latter, the item number on the nameplate is followed by
"I".

Please note the direction of flow indicated by the arrow. Do
not connect the supply and discharge lines in the opposite dir-
ection of the arrow!
Perform a leak test with suitable means.
5.3 Connecting the moisture detector (filter AGF-FA-5
only)
Filter AGF-FA-5 allows the connection of a model FF-... mois-
ture detector. The filter head has an additional G1/4 female
thread for this purpose, factory sealed with a plug.
DANGER
Explosion hazard
To operate the filter in an explosive atmosphere with mois-
ture detector, the moisture detector and controller must be
ignition protection class intrinsically safe "i". The use of non-
intrinsically safe components may result in ignition in explos-
ive atmospheres.
Also note the specifications under EN 60079-14 in this respect.
Please refer to the appendix for the assembly drawing. The
moisture detector must be screwed in tight, sealed with Te-
flon tape or sealant/flat gasket! Please be sure to run the con-
nection cable safely and without tension. Pay attention to
leaks!
If possible, the cable between the moisture detector and con-
troller should NOT be run inside conduit with switch cables, as
these may cause interference.
Please refer to the separate operating and installation instruc-
tions included with the product for addition information on
connecting the moisture detector and controller.
6 Operation and controls
NOTICE
The device must not be operated beyond its specifications.

troubleshooting and repair.
8 Maintenance
Always observe the applicable safety- and operating regula-
tions when performing any type of maintenance. Please refer
to the original operator's manual on the included CD or online
at www.buehler-technologies.com for maintenance informa-
tion.
