Operating Instructions
Filter dryer shell
ADKS / FDS / FDH
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
recommendation, consult the system / compressor
manufacturers or contact Alco
engineering department.
Installation

Do not remove seal caps until ready for installation
in order to minimi

the filtering ability, increases the pressure drop
through the filter drier shell and may cause internal
screen damage.
•
Removal of the internal components of shell is not
required before and during brazing.
•
When brazing,
wet rags or other suitable heat protection to
prevent damage to the paint surfaces adjacent the
fittings.
•
Use proper temperature for brazing/welding.

•
If the total shell weight results in excessive stress
to the piping joints, the shell must be supported by
suitable mounting bracket(s).
Installation
Before opening of
system and shell completely!
Do not remove cores from bag until just prior to
installation. Early removal could result in
contamination of the desiccant from surrounding
atmosphere.

Installation Filter Dryer Shells:
Do not remove seal caps until ready for installation
in order to minimize 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.
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/welding.
ADKS and FDS are equipped with copper fittings.
FDH is equipped with steel plated fittings. 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).
Installation/Replacement of Filter Cores:
Before opening of the Filter Drier Shell pump down
system and shell completely!
Do not remove cores from bag until just prior to
installation. Early removal could result in
contamination of the desiccant from surrounding
atmosphere.
FDS: Opening quick cap (Fig. 3, 6)
Loose the nut by two turns. Rotate the quick cap
counterclockwise and lift the quick cap from shell.
Withdraw entire internal assembly by pulling on
spring.
ADKS/FDH (Fig. 6):
Remove flange bolts and flange cover. Withdraw
entire internal assembly by pulling on handle.
Unscrew inlet block retainer.
Remove and dispose used filter drier blocks.
Clean all internal parts thoroughly.
Remove blocks from packaging.
Cores must be mounted by all means with the
tapered inside diameter against the outlet retainer.
Assemble all parts and new gaskets acc. to Fig. 6
and screw handle on the outlet retainer.
Carefully insert assembled unit into shell.
FDS: Closing quick cap (Fig. 4, 6)
After replacement of Filter Cores always check
cover and shell o-rings for damage. O-ring set has
to be ordered separately.
•
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
27Nm for FDS-24 and 34Nm for other FDS types.
ADKS/FDH: Closing flange cap
•
Make sure that the flat gasket has been properly
incorporated in the round groove of flange cap.
After replacement of Filter Cores always use new
cover gasket. Lightly coat the new gasket with
refrigeration oil on both surfaces.
•
Screw the first bolt (for FDH with washer) in a few
turns to assist with the mounting of the cap.
•
Place the cap onto the shell ensuring the cut
aligned under the first screw (and washer for
FDH). Handtighten first bold. Insert the remaining
bolts and handtighten. T
using a crisscross pattern to apply pressure evenly.
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
related to pressure.
•
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
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
inspection/service.
