amount of moisture and
come to equilibrium in
approximately one day of
operation. When either
acid or wax is the major
contaminant involved,
the cores should be left in
the system at least three
days to come to equilib-
rium thereby removing
the maximum amount of
contaminants.
Many users of replaceable
core Catch-Alls will change
the cores every Spring and
Fall as part of their normal
maintenance schedule.
Bypass Installations
For the added convenience
of operating the system
while changing drier cores,
a bypass installation is
recommended (see sketch).
Valve A would normally be
closed which would allow
all the refrigerant to flow
through the filter-drier.
Note that hand valves B
and C are required only
if it is desired to replace
the Catch-All Filter-
Drier without pumping
down the piping from the
receiver. Always pump
out the section of the line
containing the filter-drier
by closing the hand valves
A and B (note direction of
flow). After isolated section
has been pumped out, close
valve C, and then change
the core. Disposal of the
cores should be handled
according to local laws.
WARNING! Dangerous
hydraulic pressures may
develop if hand valves
B and C are closed and
the filter-drier is full of
liquid. When liquid is
trapped in a section of line,
even a slight increase in
temperature results in a
great increase in internal
pressure. Therefore, a
pressure relief device
is recommended, as
indicated.
Replaceable Cores
Cores are dried and
individually sealed in
hermetic containers. The
drier shells are shipped
less cores. Cores should
be ordered separately, as
follows:
RCW-42
High Water Capacity
Core – Order as separate
item – Fits ONLY shell
types C-R424, C-R425,
and C-R427. Designed
specially for use with
POE oils. This core should
be used on systems that
have a ruptured water
cooled condenser, or that
have been exposed to the
atmosphere, or for some
reason have a high amount
of moisture in the system.
RC-4864
Activated Core – Order as
separate item – Fits types
C-480 thru C-19200 Series
shells. This is the standard
core suitable for most
installations in the liquid
or suction line.
RCW-48
High Water Capacity
Core – Order as separate
item – Fits types C-480
thru C-19200 Series shells.
Designed specially for use
with POE oils. This core
should be used on systems
that have a ruptured water
cooled condenser, or that
have been exposed to the
atmosphere, or for some
reason have a high amount
of moisture in the system.
RC-4864-HH
Activated Charcoal Core
– Order as separate item
– Fits types C-480 thru
C-19200 Series shells.
This core should be used
for wax removal on low
temperature R-22 and
R-502 systems, and for
clean-up of systems that
have had a hermetic motor
burnout.
RC-10098
Activated Core – Order as
separate item – Fits types
C-30000 and C-40000
Series shells. This core
has a high water capacity
and should be used on
all standard liquid and
suction line applications.
RCW-100
High Water Capacity Core
– Order as separate item
– Fits types C-30000 and
C-40000 Series shells.
Designed specially for use
with POE oils. This core
should be used on systems
that have a ruptured water
cooled condenser, or that
have been exposed to the
atmosphere, or for some
reason have a high amount
of moisture in the system.
RC-10098-HH
Activated Charcoal Core
– Order as separate item
– Fits types C-30000 and
C-40000 Series shells.
This core should be used
for wax removal on low
temperature R-22 and
R-502 systems, and for
clean-up of systems that
have had a hermetic motor
burnout.
