Emerson Alco Controls 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. Failure to
comply can result in device failure, system damage or
personal injury.
• This product is intended for use by qualified personnel
having the appropriate knowledge and skills like trained
according to EN 13313 or a specific training for
flammable refrigerants.
• Flammable refrigerants require 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.
• Ensure that the system is correctly labelled with applied
refrigerant type and a warning for explosion risk.
• In a severely contaminated system, avoid breathing acid
vapours and avoid contact with skin from contaminated
refrigerant / lubricants. Failure to do so could result in
injury.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Do not release any refrigerant into the atmosphere!
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Observe and avoid mechanical damage of component
housing.
• Do not use any other fluid media without prior approval
of EMERSON. Use of fluids not listed could result in:
- Change of hazard category of product and
consequently change of conformity assessment
requirement for product in accordance with European
Pressure Equipment Directive 2014/68/EU.
- Chemical deterioration of desiccants of core in the
shell.
• Ensure that design, installation and operation comply
with European and national standards/regulations.
• For flammable refrigerants only use valves and
accessories approved for it!

Filter-Drier Series BFK-...FLR
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.
I n s t a l l a t i o n :
• Do not remove seal caps until ready for installation in
order to minimize entering of moisture and dirt.
• WARNING: Avoid damaging the connections!
B r a z i n g : ( F i g . 1 )
• Perform 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 as follows:
- according to EN 378 for systems which must comply with
European pressure equipment directive 2014/68/EU.
T i g h t n e s s T e s t :
Conduct a tightness test according to EN 378-2 with
appropriate equipment and method to identify leakages
from joints and products. The allowable leakage rate must
be according to system manufacturer's specification.
WARNING:
• Failure to pressure test or tightness test as
described could result in loss of refrigerant, damage
to property and/or personal injury.
• The tests must be conducted by skilled personnel
with due respect regarding the danger related to
pressure.
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 :
• Disconnect electrical power before service.
• 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.
• According to EN 378-4 during
maintenance, tightness tests shall be carried out at the
relevant part of the refrigerating system. This shall apply
where appropriate following any repair.
• When disposing or removing the component or part
from refrigeration system, ensure that no refrigerant
remains ed trapped inside of the part.
• 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.
