Emerson BTAS-2 Serie Instrucciones De Funcionamiento

Suction line Filter dr
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).

• She ell must be as close as possible to the
com mpressor in suction line but upstream of any
vibr ration adsorber that might be presented.
• The e shell must be installed as shown in Figure 2, 3
or 4 4 which permits oil return to the compressor and
con nvenient location for removing of core or
cart tridge.
• Rem mark: Protect the shell against sunrays and
vibr ration.
• For r detailed
reco ommendation, consult the system / compressor
thoroughly.

Insta allation:
• Do not remove seal caps until ready for installation
skill. Before
in o order to minimise entering of moisture and dirt
into o shell.
• The e arrow on the label must be point in the
dire ection of refrigerant flow. Reverse flow reduces
the filtering ability, increases the pressure drop
thro ough the filter drier shell and may cause internal
scre een damage.
• Use e proper temperature for brazing of copper to
bra ss as the entire shell and fittings are solid brass.

• If th he total shell weight results in excessive stress
to t the piping joints, the shell must be supported by
pressure
suit table mounting bracket(s).
• It is s recommend to insulate the entire shell in order
to r reduce heat gain of suction gas.
• The e new gasket (F) is supplied with filter core or
filte er drier cartridge. Lubricate the new gasket (F)
spa aringly with refrigerant oil. (Fig. 5)
• Rem move the flange bolts (A), flange cover (C),
spri ing (D) and discard the flange gasket (F).
• Plac ce the new gasket (F) in groove at the top of
she ell (G).
• Rem move the filter core or filter drier cartridge (E)
from m packaging and assemble as fast as possible to
min nimise moisture contamination.

Leakage test:
• After completion n of installation, a test pressure
must be carried o out as follows:
- According to E EN378 for systems which must
comply with European pressure
directive 97/23/E EC
- To maximum wo orking pressure of system for other
applications
Warning:
1) Failure to do so could result in loss of refrigerant
and person injury.
2) The pressure te est must be conducted by skilled
persons with due e respect regarding the danger
related to pressure.
Operation:
• Start the compr ressor and put the system in
operation. Reco ord the pressure drop on the
enclosed label an nd attach to the side of shell (G).
