IMPORTANT:
To avoid hazardous or dangerous
condition, read and understand all of the
instructions and safety information in this
instruction sheet.
— NOTICE —
Retain instructions for future reference.
WARNING
• De-energize all electrical circuits prior to and
during installation and maintenance.
Special instructions:
• Installation should only be conducted by qualified installers in
accordance with NEC and any local codes or engineering
requirements.
• All mixing containers must be thoroughly cleaned and free of
any contamination prior to mixing any compound.
• Take precaution to locate fitting in the exact location specified
by all NEC and engineering requirements and/ or all local
codes.
• Ensure sealing fitting is free of all debris and foreign material
and that it is clean and dry to ensure adhesion of sealing
compound.
• Install sealing fitting into conduit system with “Pour Hole”
upward and “Cover Hole” and “Pour Hole” easily accessible (See
Figure 1). Install conduit ONLY as indicated. Do not install
conduit into “Cover Hole” or “Pour Hole”.
• Pull required conductors through sealing fitting ensuring
conductor insulation is continuous, and that conductors are
clean and dry, and free of nicks or abrasions.
Maximum conductor fill for sealing fittings are listed in the
— NOTICE —
table on page 4.

• Remove “Cover Plug” and “Pour Plug” from sealing fitting.
Confirm sealing fitting is securely attached to both conduit
runs and that conductors are continuous and undamaged.

Installation Instructions:
Step 1: Prepare dam as noted below according to orientation:
• Vertical packing sealing fiber
– Bundle all conductors into single bundle in center of sealing
fitting. Insert sealing fiber through “Cover Hole” in lower
section of sealing fitting and loosely pack around conductor
bundle. Sealing fiber cannot be higher than the “Conduit
Bushing/End Stop”.
– Completely separate conductors in bundle so that they are
not touching and pack sealing fibers in surrounding spaces.
Conductors cannot touch another conductor or inside
surfaces of sealing fitting. The sealing fiber cannot be
higher than the “Conduit Bushing/End Stop” and dense
enough to prevent ingress of liquid sealing compound. All
sealing fiber must be confined to the “Conduit Bushing/
End Stop” section of the fitting.
• Horizontal packing sealing fiber
– Bundle all conductors into single bundle in center of sealing
fitting. Insert sealing fiber through “Cover Hole” in left and
right sections of sealing fitting and loosely pack around
conductor bundle. Sealing fiber cannot be beyond “Conduit
Bushing/End Stop” inside center section of sealing fitting
– Completely separate conductors in bundle so that they are
not touching and pack sealing fibers in surrounding spaces.
Conductors cannot touch another conductor or inside
surfaces of sealing fitting. The sealing fiber should not be
packed beyond the “Conduit Bushing/End Stop” and dense
enough to prevent ingress of liquid sealing compound. All
sealing fiber must be confined to “Conduit Bushing/End
Stop” section of fitting.
THIS IS NOT AN INSULATING COMPOUND AND MUST NOT BE
USED FOR SUCH PURPOSE.
DO NOT use compound if it has begun to set. DISCARD and
prepare new batch.
Keep compound dry. Keep cover closed when not in use
• Prepare sealing compound ONLY at temperatures above
40°F (4°C) and ONLY pour into fittings that have been
brought to a temperature above 40°F (4°C). Seals must
NOT be exposed to temperature below 40°F (4°C) for at
least 72 hours.
• Material hardens and becomes warm to touch. May cause
skin, eye and respiratory irritation. DO NOT dispose of
in drain.
Step 4: Pour sealing compound
• Pour prepared sealing compound into sealing fitting through
“Pour Hole” (Vertical Installations) or “Cover Hole” (Horizontal
Installations). Lightly tap on fitting to disperse and level sealing
compound in and around sealing fitting and conductors. Fill
sealing fitting until sealing compound level is at sealing
compound “Fill Line” inside sealing fitting. Never under-fill.
Step 5: Install pour hole plug
• Install “Pour Plug” into sealing fitting “Pour Hole” opening and
tighten until secure.
Step 6: Mark the fitting complete
• (Recommended practice) Mark the sealing fitting complete by
painting or equivalent method once sealing compound has
been poured and cured.
If tool is needed to pack sealing fiber, ONLY use blunt tipped
non-metallic object.
Step 2: Replace cover plug
• Install :Cover Plug” into “Cover Plug” opening and tighten until
secure.
Step 3: Prepare sealing compound for Crouse Hinds’ Sealing
compound.
Instructions and warnings must be followed.
A) Instructions for use with Crouse Hinds Chico®
Sealing Compound:
• Prepare Chico® sealing compound as instructed using a clean
mixing vessel for each batch. Mix two part compound to one
part cold water by volume. Mixture must be blended
immediately to a smooth consistency with no lumps. Do not
mix more compound than can be poured in 15 minutes.
B) Instructions for use with Crouse Hinds Chico® APX
Sealing Compound:
• Squeeze pouch until inner liquid container breaks. Shake pouch
until compound and water are thoroughly mixed. Remove
screw cap, insert flexible spout and pour into fitting.

Installation Instructions:
®
For T&B
EYD drain sealing fittings:
• Follow all vertical pour instructions (except as indicated below)
for EYS fittings listed on page 2, Steps 1, 3, 4, 5, 6, 7 and Figures
2 and 3 (below).
Avoid contact between the probe and the conductors.
Trade sizes: ½" through 1"
• Install Drain Seal Fittings in conduit run in accordance with
applicable codes. Pull conductors through following fill
requirements detailed in table on page 4.
• Access inside of Drain Sealing Fitting by removing pipe plug.
• Install drain probe through drain opening and firmly secure
probe in place, making sure ‘Thread Protector’ is positioned to
eliminate sealing compound from entering threads. Adjust
length of probe to ensure that top stem is above anticipated
sealing compound level.
Sealing compound must completely surround conductor.
Poured seals must not be disturbed during the “Curing
Period” of the sealing compound (72 hours).
Trade sizes: 1¼" through 4"
• Install drain seal fittings in conduit run in appropriate location in
accordance with applicable codes. Pull conductors through
following fill requirements detailed in table on page 4.
• Remove large cover plug to access inside of Drain Sealing fitting.
Follow all vertical pour instructions for EYS fittings listed on page
2, Steps 1 (vertical) or 2 (horizontal), 3, 4 (orient cover plug with
arrow pointing down), 5, 6, 7, and Figures 4 and 5 (below).
• Install drain probe through drain opening and secure, making
sure that the ‘Thread Protector’ is positioned to prevent sealing
compound from entering threads. Adjust length of probe to
ensure top stem is above the anticipated sealing compound level.
