Gardner Bender BV208D - Manual (Page 2)

Operation
Blo-Vac motors are not explosion
proof. Do not operate Blo-Vacs in
underground locations or where flammable vapors
exist.
IMPORTANT: Read all operating instructions prior to
using Blo-Vac System.
1. Connect power cord to 115 VAC outlet on a 20 amp
circuit.
2. Connect the 8 foot hose to either the inlet or outlet
fitting on the Blo-Vac (see Figure 2). The outlet is for
blowing and the inlet is for vacuuming.
3. Select a seal-off, seal-off body and line carrier to
match the size conduit on the job (see “Line Carriers”
and “Pull Line ” for more information). The same items
are required for vacuuming or blowing into conduit.
4. Using the vacuuming method requires two people. The
Blo-Vac and the operator are at one end of the
conduit, another person is required to feed the line
carrier and pull line into the opposite end of the
conduit. Blowing pull line can be accomplished by one
person.
a. Conduit sizes 1/2" to 1-1/4"
i.
Use the BV12 hose adapter, JV08 seal-off or the
long JV09 Seal-off. The
JV07 can also be used
(see Figure 3).
ii. Thread the JV08 into the
BV12 adapter. Insert the
adapter into the hose
assembly.
iii. Inject pull line into the
conduit by selecting a
line carrier and attaching
the pull line to it. If a
Power Saver Line
Package is used, a
separate line carrier is
not needed.
iv. Power Savers and Tag-a-Longs are center
dispensing. Unwind about 12 inches of pull line
prior to placing the line carrier into the conduit.
Wrap the loose end around the blower hose or a
stationary object.
v. Place the line carrier into the conduit.
Be sure the pull line is not tangled
around feet or hands of the
operator. Fast moving pull can cause severe burns to
exposed skin.
vi. Position the seal-off in the end of the conduit. The
loose end of the pull line should be between the
seal-off and the conduit.
vii. Turn the Blo-Vac "ON" and continue operating
until the line carrier exits the opposite end of the
conduit.
b. Conduit Sizes 1/2" to 2-1/2"
i. Injecting bulk line into 1/2 to 2-1/2" conduit
requires the JV07
Dial-A-Line
body, BV12
adapter and
either the JV08
or BV23 seal-off
(see Figure 4).
ii. Thread the end
of bulk line into
the round hole in
the metal disk
on back of the
JV07. Pull the
end through the
body and into
the seal-off.
iii. Tie the pull line
to the line
carrier. Insert
the line carrier into
the conduit and operate the Blo-Vac by placing the
seal-off against the conduit opening and turning
the Vac system "ON". Operate the Blo-Vac until
the line carrier exits the opposite end of the
conduit.
