I. Blowing or Vacuuming Through Conduit
Select the Power Saver™ line package for size and
length of line to fit the conduit. It is recommended that
you flex the package back and forth two or three times
to loosen it. This will make the line easier to dispense.
Blowing a line in the conduit
1. Insert the hose in the blower side of the Blo-Vac™
power unit.
2. Insert the BV12 hose adapter in the other end of
the hose. Screw the handle end of the JV07
Dial-A-Line™ body into the hose adapter. Select
either the JV08 or JV09 seal-off and screw it into
the JV07. FIGS. 20, 21 and 22
3. Pull out approximately
two feet of line and
hold on to trailing end.
4. Insert the line package
in the conduit — foam
tip first.
5. Hold the seal-off cone
firmly in the conduit
entrance and turn on
the blower. Blow the
line package through
the conduit.
6. It is recommended
that the ends of the
line be tied off, to
prevent it from being
accidentally pulled into
the conduit.
Vacuuming a line in the conduit
1. Insert the hose in the vacuum side on the Blo-Vac™
power unit.
2. Assemble the hose and seal-off as in Item 2 above.
3. At the far end of the conduit run, pull out
approximately two feet of line and tie off the trailing
end of the line.
4. Insert the line package
in the conduit — foam
tip first.
5. Return to the other end
of the conduit and
power unit.
6. Hold the seal-off cone
in the conduit and turn
on the power unit and
vacuum the line
package through
the conduit.
Tag-Along™ Line Package
Tag-Along™ line packages perform the same function
as Power Saver™ line packages except they are used
in 1
1 ⁄ 4 ” diameter and larger conduit. Tag-Along™
package must be used with a line carrier to supply the
pulling force.
Select the Tag-Along™ line package and a line carrier
either foam or inflatable that fits the conduit diameter and
proceed as follows:
If a foam line carrier is selected—
1. Attach the Tag-Along™
line package plastic eye
to hook. Pull out
approximately two feet
of line. Tie off the ends
of the line to prevent it
from being accidentally
pulled into the conduit.
2. Insert the foam line
carrier and Tag-Along™
package in the conduit.
3. Select the seal-off that
best fits the conduit —
JV07 Dial-A-Line™ body
with the JV12 seal-off or
the B26 Dial-A-Line™
body with the BV23 or
BV24 seal-off.
4. Hold the seal-off rubber
cone firmly in the
conduit and turn on the
power unit. The run time
will be longer than that
for the Power Saver™ line package because of the
larger conduit and greater volume of air required.
However, the run time in 3” and 4” conduit
200 to 300 feet long should be complete in
10 to 15 seconds.
