Suction line Filter drier shell Suction line Filter drier shell
General information:
ALCO BTAS suction line filter drier shell with
replaceable core is for new installation and
integrating into the systems after compressor
burnout, retrofit and maintenance.
• BTAS is only for installation in suction line.
Warning: Do not use BTAS on liquid line
applications.
!
Safety instructions:
• Read installation instruction
Failure to comply can result in device failure,
system damage or personal injury.
• It is intended for use by persons having the
appropriate knowledge and
attempting to install the shell make sure
pressure in system is brought to and remains at
atmospheric pressure.
• Do not release any refrigerant into atmosphere.
• Do not use any other fluid media without prior
approval of Alco Controls. Use of fluid not
listed could result in:
− Change of hazard category of product and
consequently change of
assessment requirement for product in
accordance with European
equipment directive 97/23/EC
− Chemical deterioration of desiccants of core
in the shell
• 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 skin injury.
• The filter dryer shell must be used only for the
purpose it is designed for.
Mounting location:
• Allow sufficient clearance from the flanged end to
permit removal of the shell's entire internal
components assembly (see fig. 1).
