• The National Electrical Code in Article 501 Section 501.15 Class I, Division 1 and 2, requires that seals be installed in specific
locations. This is to prevent the passage of gases, vapors or flames through the conduit from one portion of the electrical installation to another portion.
• Appleton sealing unilets are UL listed for use in hazardous locations with Appleton Kwiko A compound or Crouse Hinds Chico
A compound only. These compounds, when properly mixed and poured, hardens into a dense and strong mass which is insoluble in
water, is not attacked by petroleum products and is not softened by heat.
• The following sealing fitting series are UL listed for use with Appleton Kwiko A or Chico A sealing compounds:
EYF, EYF-AL, EYM, EYM-AL, EYDM, EYDM-AL, EYD, EYS, EYSF, EYSF-AL, EYSM, EYSM-AL, ESUF, ESUM

WARNING:
Fai lure to follo w saf ety instr ucti o ns may
caus e i g n ition of haza r d o us atmosphe re
resulting in serious personal injury and / or
property damage.
STEP 1.
Install unilet and pull conductors through.
• Remove plug(s) from sealing fitting and
use fiber filler to make dam (s) in hub(s).
STEP 2.

C e m e n t . B e
sure to read the
mi xi ng ins tr uctions on Sealing
cement can.
DAMMING: Separate each conductor and
pack fiber filler tightly into hub(s) behind
conductors and around each conductor.
• These conductors must not touch each
other nor the sealing fitting wall.
• Clean fiber shreds away from walls or
conductors to prevent them from causing
flame and / or leakage of gases. Finished
dam must be flush with conduit hub
bushing.
CAUTION
Refer to Table 1 to determine the
maximum number and size of conductors allowed in a seal. (Page 4)
STEP 3.
MIxing: Prepare sealing compound using a completely
clean mixing vessel in each batch. Shake the sealing
cement thoroughly in all directions. Mix sealing cement
with correct proportion of clean water as noted below.
APPLETON Kwiko A and CROUSE -HINDS Chico A
CEMENT. Add one (1) part water to two (2) parts cement
by volume. Use cold water, warm water increases setting
speed. Add water and stir immediately and thoroughly.
• DO NOT mix more than can be poured in 15 minutes
after adding water.
• These cements are NOT INSULATING COMPOUNDS
and MUST NOT be used for such purposes.

CAUTION: TEMPERATURE/CURE TIME
APPLETON Kwiko A and CROUSE-HINDS Chico A
CEMENT
FOR GROUPS C AND D APPLICATIONS: Sealing com-
pound to be mixed ONLY at temperatures above 35º F (1.7º
C) and ONLY poured into fittings that have been brought to
a temperature above 35º F (1.7º C). Seals must NOT be
exposed to temperatures below 35º F (1.7º C) for a least 8
hours. Compound must be allowed 8 hours to cure to full
strength before energizing system.
FOR GROUPS A AND B APPLICATIONS: Sealing compound to be mixed ONLY at temperatures above 40º F (4.4º
C) and ONLY poured into fittings that have been brought to
a temperature above 40º F (4.4º C). Seals must NOT be
exposed to temperatures below 40º F (4.4º C) for a least 72
hours. Compound must be allowed 72 hours to cure to full
strength before energizing system.
STEP 4
VERTICAL CONDUIT RUN. Pour sealing cement mixture into
the small pipe opening until the cement is level with the last
thread of the opening. Replace and tighten small pipe plug.
HORIZONTAL CONDUIT RUN. Pour sealing cement mixture
into the unilet through the large opening until two (2) to three
(3) threads are covered with the cement.
• Replace and tighten in sequence the large pipe plug or cover
the small pipe plug into the unilet and the small pipe plug into
the cover.

4. Replace the large threaded cover so that the threaded hole
is facing downward.
5. Insert the tube and wire drain core into the opening of the
large threaded cover so that the end being inserted will be
above the compound in a completed seal.
(See illustration above).
6. Be sure that the tube and wire drain core do not touch any
of the conductors, Otherwise, this will expose the conductors
in the completed and hardened seal.
(See illustration above).
7. Mix Sealing Cement with the correct proportion of water per
instructions provided with the cement. (Page 1, Step 3).
8. Pour Sealing Cement mixture into the Unilet through the
opening located above the large cover until the last thread
is covered with cement.
9. After cement has cured, (See page 1, "Caution: Temperature

NOTE: On sizes 3-1/2" and 6" the cover should be tightened down with
the small pipe plug removed from it. This will allow excess cement or air to
escape out rather than seeping through or pushing the dam into the conduit.
When the large cover has been tightened fully, replace pipe plug.
Vertical conduit
1. Install Unilet and pull conductors through.
2. Remove the pipe plug where the cement will be poured
through and the large pipe plug or cover with the small pipe
plug for size 3-1/2"-6" at the center of the Unilet.
3. Dam the lower hub with fiber filler. (Page 1, Steps 1 & 2.)
4. Replace the large pipe plug or cover with the small pipe
plug for 3-1/2" thru 6" and tighten all threaded joints securely.
5. Mix Sealing Cement with the correct proportion of water
per instructions provided with the cement. (Page 1, Step 3).
6. Pour Sealing Cement mixture into the small pipe plug
opening until the cement is level with the last thread of the
opening.
7. Replace and tighten small pipe plug.
Horizontal conduit
1. Install Unilet and pull conductors through.
2. Remove all pipe plugs and / or cover from the Unilet.
3. Dam both hubs with fiber filler. (Page 1, Steps 1 & 2)
4. Mix Sealing Cement with the correct proportion of water
per instructions provided with the cement. (Page 1, Step 3).
5. Pour Sealing Cement mixture into the Unilet through the
large opening until 2-3 threads are covered with the cement.
Fill hole must be oriented in the upright position.
6. Replace and tighten in sequence the large pipe plug or
cover, the small pipe plug into the Unilet and the small pipe
plug into the cover.
