Emerson BFK FLR Serie Betriebsanleitung

G e n e r a l i n f o r m a t i o n :
BFK-...FLR Bi-flow filter-driers are used for
protection of systems against contaminant.
The listed products are not in scope of ATEX product
directive 2014/34/EU as they do not incorporate an own
source of ignition.
It is not intended for use in an environment with dust
circulation such as mining and silos, as device has not
been released for this type of applications nor
electrostatic charge potential has been verified.
BFK-...FLR must be installed in an appropriate
housing to protect them from mechanical damage or
shock.
!
S a f e t y i n s t r u c t i o n s :
• Read operating instructions thoroughly. Non-
observance can result in device failure, system
damage or personal injury.
• According to EN 13313 it is intended for use by
persons having the appropriate knowledge and
skill.
• R290 requires special handling and care due to its
flammability. Sufficient ventilation is required
during service of the system. Contact with rapidly
expanding gases can cause frostbite and eye
damage. Proper protective equipment (gloves, eye
protection, etc.) has to be used.
• In a severely contaminated system, avoid
breathing acid vapors and avoid contact with the
skin from contaminated refrigerant/lubricants.
Failure to do so could result in injury.
• Ensure that the system is correctly labeled with
applied refrigerant type and a warning for
explosion risk.
• Do not release any refrigerant into the
atmosphere.
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Do not use on any other fluid media without prior
approval of EMERSON. Use of fluids not listed
could result in chemical deterioration of the
desiccant in filter-drier.
• Ensure that design, installation and operation are
according to European
standards/regulations.
M o u n t i n g l o c a t i o n :
• Filter-driers may be installed in any position within
the liquid line.
• Protect the filter-drier against sunrays and vibration.

B r a z i n g ( F i g . 1 ) :
• Perform and consider the brazing joint as per
EN 14324.
• Before and after brazing clean tubing and brazing
joints.
• Minimize vibrations in the piping lines by
appropriate solutions.

P r e s s u r e t e s t :
• After completion of installation, a pressure test must
be carried out per EN 378 for systems which must
comply with European pressure equipment directive
and national
14/68/EU.
!
W a r n i n g :
• Failure to do so could result in loss of refrigerant
and personal injury.
• The pressure test must be conducted by skilled
persons with due respect regarding the danger
related to pressure.

T i g h t n e s s t e s t :
Conduct a tightness test per EN 378-2 with appropriate
equipment and method to identify tightness of external
joints. The allowable leakage rate must be according
system manufacturer's specification.
O p e r a t i o n :
• After leakage test start system and after sufficient
running time check colour of moisture indicator for
moisture level. We recommend the use of
EMERSON moisture indicators.
• In systems with excessive moisture it may be
necessary to replace the filter-drier for several times
in order to bring moisture in the system to a safe
level.
!
S e r v i c e / M a i n t e n a n c e :
• Before any debrazing ensure that the flammable
refrigerant is pumped out of the system and the
room around the system is well vented so no
refrigerant left.
• Disconnect electrical power before service.
• Always install a new filter-drier when existing
ones become saturated with moisture and foreign
materials.
• Do not attempt to dry out a used filter-drier.
