Install Instructions

from contamination by
moisture and dirt. The
detailed instructions for
assembly and changing
cores are given on these
cans. The following
condensed instructions may
be used if these cans are not
available.
1. Make sure all the refrig-
erant is pumped out of
the Catch-All shell. The
appropriate shut-off valves
should be tightly closed.
2. Remove the end plate
and internal assembly, and
clean the internal parts.
Remove the activated core
from the sealed can using
caution when doing so. The
metal pull tab and pull strip
permit the can to be rolled
opened with the key or a
pair of pliers. Do not replace
the end plate gasket unless
it is damaged. When replace-
ment is necessary, select the
outer gasket from the set
supplied with each core.
Do not cut or abrade the
gaskets used in the end
plate.
3. Remove the end spring,
wing screw, and inlet plate
from outlet plate assembly.
Remove core spacer
plates from assembly (if
applicable). If desired, install
secondary filter. (Detailed
installation instructions are
packaged with the secondary
filter.) Assemble the molded
cores and use the core spacer
plates as required. After the
cores are assembled, position
inlet plate on the end of
the tubular screen. Fasten
finger tight the wing screw
to assembly. The screw,
when properly fastened,
tightens the components in
the assembly thereby prohib-
iting component movement
and dirt bypassing around
the cores. Assemble the end
spring on to the wing screw.
The design of the screw
holds the spring in position
so that the end plate can be
easily installed (especially
when the shell is mounted
horizontally). The end spring
is designed to fit into the
circular groove on the end
plate.
4. Insert the assembly
in the shell, replace the
flange bolts, tighten evenly,
using a star pattern, to
the recommended torque
value, 25-30 ft-lbs for the
C-R420 Series, the C-480
thru C-19200 Series, and the
C-30000 and C-40000 Series.
5. For C-R424, C-R425, and
C-R427 models - do not
remove the outlet strainer
assembly or gasket. On these
models, the core retainer
assembly with the spring is
the only part that must be
removed to change the core.
Caution
The edge of the shell fits
into the gasket groove on
the end plate and makes a
seal against the gasket to
prevent refrigerant leakage.
Be careful not to scratch or
damage the edge of the shell
when changing the cores. If
the edge of the shell should
become damaged, replace
the shell to prevent possible
refrigerant leakage.
Special Conditions Of
Use
Warning:
To avoid electrostatic
charging steps must
be taken to ensure the
equipotential bonding is
maintained.
Warning:
To avoid a possible
electrostatic charge only
clean with a damp cloth.
Operating fluid temp
shall be limited to a range
of -46°C (-50°F) to 65°C
(149°F).
When to
Change Cores
Cores should be changed
when they become contami-
nated, or on a regular
maintenance schedule.
Disposal of the cores should
be handled according to local
laws. Cores that become
contaminated with solid
particles should be changed
whenever the pressure drop
increases to the point where
it reduces system perfor-
mance. When moisture is
the major concern, change
the drier cores according
to the indication of the
See•All Moisture & Liquid
Indicator. The cores will
remove their maximum
