Gardner Bender BV208DA Blo-Vac - Manual (Page 8)

7.9 Blowing or Vacuuming Through Con duit
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. See Figures 20,
21 and 22.
3. Pull out approximately 2' 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 2'
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 2' 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'
long should be complete in 10 to 15 seconds.
