Emerson FDS-24 Serie Instructions De Service

General information:
ALCO filter dryer shells with replaceable core/filter
are for new installation or for integration into the
system for cleanup purpose after compressor motor
burnout.
!
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 conformity assessment
requirement for product in accordance with
European pressure equipment
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).
1) Liquid line
• Locate shell as close as possible to the inlet of
expansion valve. If solenoid valve and sight glass
are incorporated, the arrangement will be in the
following sequences in flow
refrigerant and as close as possible:
- Filter dryer shell, solenoid valve, sight glass and
expansion valve.
Remark: Protect the shell against sunrays and
vibration.
2) Clean-up after compressor motor burnout
• Shell must be as close as possible to the
compressor in suction line but upstream of any
vibration adsorber that might be presented.
• Filter drier shell shall be installed vertically with
up side flange/quick cap or as shown in Fig. 2
which it will permit the return of oil to the
compressor.
