The Emerson Advantage
Emerson suction line filter-driers incorporate a protective
filter, plus desiccant blended for maximum moisture and
acid removal. Compressor manufacturers recommend the
installation of suction line filter-driers to protect their
equipment from contaminants left in the system after a
burnout. These suction line filter-driers include protection
from moisture and organic or inorganic acids, resulting
from burnouts, or chemical changes in the system
refrigerant or oil. They are specially suited for system
clean-up after a burnout, or when major work has been
performed on the system.
Safety and Installation Instructions
1. Read these instructions thoroughly. Failure to follow
instructions may result in drier failure, system dam-
age, or personal injury.
2. The system must be pumped down and line depres-
surized before attempting to install. Failure to do so
can result in personal injury
3. Caution: Extreme care should be taken in handling
contaminated refrigerant to prevent personal injury.
Failure to do so may result in personal injury.
4. Do not remove seal caps until ready for installation.
The seal caps should be removed by unscrewing the
plastic caps if SAE connections, or pulling out with
long nose pliers if ODF connections.
5. Caution: Do not install access valve cores until all
brazing is completed. Installation prior to brazing may
cause damage to valve cores seals.
6. The filter-drier may be installed in any position. For
best results, locate the filter-drier as close as possible
to the inlet of the compressor installation upstream of
vibration eliminators is suggested. When the piping
arrangement results in excessive stress on refrigerant
line, the filter-drier should be supported by a suitable
bracket.
Refer to Table 1 for roughing-in dimensions.
7. Warning: Install with arrow pointing in direction of
flow (toward compressor). Reverse flow may
cause internal damage.
8. Clean and deburr piping ends to provide a good
brazing surface.
9. Use an inert gas, such as nitrogen, to pass thru the
lines while brazing to prevent formation of copper
oxides.
10. High temperature brazing alloys may be used.
Normal precautions should be taken by directing the
flame away from the filter-drier shell. Use chill blocks,
wet rags, or other suitable heat protection for the filter-
drier.
11. When the shell has cooled, install valve cores with
tool provided and replace seal caps. Do not charge
system until valve cores are installed.
12. To prevent twisting the refrigerant line, use a back-up
wrench on the flats supplied on SAE connections.
13. Warning: Thoroughly leak-test the system after
installation. Failure to do so could result in loss of
refrigerant.
14. The products listed on this sheet should not be used
for liquid line or hot gas applications.
Selection Warning
Emerson suction line filter-driers are intended for use on
the following refrigerants up to the maximum working
pressure marked on the product: CFC’s, HFC’s, HCFC’s,
mineral oil, POE and Alkybenzene.
Do not use Emerson suction line filter-driers on any other
fluid media without written approval of the Emerson
Climate Technologies Flow Controls Division Applications
Engineering Department. Use on fluids not listed could
result in chemical deterioration of the filter-drier.
