Gardner Bender BV208DA Blo-Vac - Manual (Page 9)

If The Inflatables ® line carrier is used—
1. Select The Inflatable ® line carrier and attach the
Tag-Along™ line package to the wire. Pull out
approximately 2' of line and hold on to the trailing end.
2. Unfurl The Inflatables ® line carrier and place it in the
conduit — bag portion first. See Figure 24.
3. In large conduit: (4", 5" and 6" diameter), it may be
necessary to point the seal-off nozzle at the plastic
sleeve of the Inflatable
® to achieve initial inflation. This is
accomplished by tilting the seal-off in the conduit
entrance. Otherwise, the Inflatable
® in its collapsed state
may allow the stream of air to blow past it.
Blowing Pull Line in the Conduit
All GB/JetLine
® systems may be used to blow pull line or
nylon line in the conduit. Position Blo-Vac™ systems in a
location that allows good access to the conduit entrance. See
Figure 25.
Set-up as follows:
1. Insert the hose in the power unit blower port.
2. Select the JV07 Small Dial-A-Line™ body that accepts
the JV08, JV09 or JV12 Seal-off for conduit sizes 1 ⁄

" or the B26 Large Dial-A-Line™ body that
accepts the BV23 or BV24 Seal-off for conduit sizes 1 1 ⁄
4
"
through 6".
3. Connect the hose to the Dial-A-Line™ body and thread
the pull line through the feed port. See Figures 26, 27
and 28.
4. Select the appropriate size line carrier and tie the pull
line securely to the line carrier to prevent loss of the line
in the conduit.
5. Insert the line carrier in the conduit and hold the seal-off
firmly in the conduit entrance and turn on the blower.
