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 thoroughly. 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
skill. Before 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 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).
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 direction of 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.
• For detailed clean-up procedure and recommendation, consult the system /
compressor manufacturers or contact Alco controls application engineering
department.
Installation:
• Do not remove seal caps until ready for installation in order to minimise
entering of moisture and dirt into shell.
• The arrow on the label must be point in the direction of refrigerant flow.
Reverse flow reduces the filtering ability, increases the pressure drop through
the filter drier shell and may cause internal screen damage.

Operating Instructions
Filter dryer shell ADKS/FDS
• Removal of the internal components of shell is not required before and during
brazing.
• When brazing, direct flame away from shell. Use wet rags or other suitable heat
protection to prevent damage to the paint surfaces adjacent the fittings.
• Use proper temperature for brazing of copper to copper as the fittings of shell
are solid copper. Do not exceed 675°C flame temperature.
• If the total shell weight results in excessive stress to the piping joints, the shell
must be supported by suitable mounting bracket(s).
Leakage test:
• After completion of installation, a test pressure must be carried out as follows:
- According to EN378 for systems which must comply with European pressure
equipment directive 97/23/EC
- To maximum working pressure of system for other applications
Warning:
1) Failure to do so could result in loss of refrigerant and person injury.
2) The pressure test must be conducted by skilled persons with due respect
regarding the danger related to pressure.
Operation:
Opening quick cap, FDS (Fig. 3)
• Loose the nut by two turns. Rotate the quick cap counterclockwise and lift the
quick cap from shell.
Closing quick cap, FDS (Fig. 4)
• Insert the core holder assembly into the shell (see core installation instructions
for details).
• Place the quick cap on the shell, push it against shell and rotate the quick cap
clockwise until the red marks are next to each others. Fasten nut with 27 Nm
for FDS-24... and 34 Nm for other FDS types.
Closing flange cap, ADKS
• Insert the core holder assembly into the shell (see core installation instructions
for details).
• Make sure that the flat gasket has been properly incorporated in the round
groove of flange cap.
• Place the flange cap on top of shell and push the flange against the shell. Screw
bolts and fasten all bolts evenly in a criss-cross pattern to a torque of 35 Nm.
• After leakage test, start system and after sufficient running time, check colour
of moisture indicator for moisture level. We recommend the use of ALCO
moisture indicators with a sensitivity of 3%. The colour calibration of ALCO
moisture indicator provide a positive and precise indication of the system's
moisture condition.
• In systems with excessive moisture it may be necessary to replace core(s) for
several times in order to bring moisture in the system to a safe level.
Warning:
During operation of system, the shell may have a high surface temperature.
Service hints
The external surface of shells are coated by epoxy powder painting for optimum
protection against corrosion. The external surface of shell shall be checked as per
EN-378 during routine/periodic inspection/service.
