WARNING
■
Dangerous hydraulic pressures
may develop if hand valves
B and C are closed and the filter-
drier is full of liquid. If there is a
possibility of inexperienced per-
sonnel closing the valves without
pumping down, a pressure relief
device is recommended.

BRAZING AND SOLDERING
The solder fittings on sealed model and
replaceable core Catch-All Filter-Driers
are copper. Copper fittings are suitable
for all types of brazing and soldering
alloys including soft solder, 95-5 solder,

CAPILLARY TUBE SYSTEM
The C-032-CAP Catch-All is designed spe-
cifically for capillary tube systems. This
unit consists of a C-032-S with 1/4” cop-
per tubes brazed into each end, giving an
overall length of 5.81”/148 mm. Capillary
tubes of any size may be inserted into the
1/4” copper tube on this Catch-All, then
the tubing pinched down, and soldered.
In this way the excellent contaminant
removal qualities of the Catch-All can
be used on domestic refrigerators and
freezers. The C-032-CAP-T model has an
access valve for charging purposes.
The best filter-drier location is imme-
diately ahead of the capillary tube. The
amount of liquid refrigerant that the
smaller size Catch-All Filter-Driers will
contain at 100°F/38°C is shown in table
below.
■
BYPASS INSTALLATION
It is preferred that the Catch-All Filter-
Drier be installed in the main liquid line
for maximum protection. When located in
a bypass line, dirt or foreign material may
pass into the system through the unpro-
tected main line.
When a bypass installation is necessary
(see illustration), a hand throttling valve A
is recommended. By throttling valve A, a
certain portion of refrigerant can be made
to pass through the filter-drier. Note that
hand valves B and C are required only
if it is desired to replace the filter-drier
without pumping down from the receiver.
Always pump out the section of the line
containing the filter-drier by closing hand

Application – Installation
Sta-Brite solder, silver brazing alloy, Sil-
Fos, or phos-copper alloys. The fittings
on the Catch-All have been carefully
cleaned and sealed before shipment,
and do not require further cleaning
before brazing. Proper brazing tech-
nique involves using a wet cloth draped
around the shell, and/or the use of
Parker Virginia Thermal Block™, and
proper torch tip for rapid heating, and
also directing the flame away from the
Catch-All shell.

SEAL REMOVAL
The normal procedure in removing seals
from either solder or flare connections
is to gently cut them away with a knife,
as shown in the illustration. With flare
connections caution should be exercised
to avoid damaging the flare surface. The
seals cannot be removed and replaced
without tearing them.
If bypass is absolutely
necessary, install as shown
