Description

Blo-Vac™ power fishing systems, BV208DA. Each
model is designed for blowing or vacuuming pull line into
electrical conduit. In addition, each Blo-Vac also
operates as a standard shop type wet and dry vacuum
cleaner.

The Blo-Vac unit has three compartments which are
easily separated. The top section contains the power
unit, the center
section(recovery
compartment) collects refuse
and the bottom section (tool
storage) is storage for
accessories (see Fig. 1).
Model BV208D is expandable
to 9 gallons. The BV208D is
constructed from high impact
polypropylene.

Blo-Vac Power finishing
system is capable of injecting
cable pull line into 1/2" to 6"
conduit. Accessories and
materials vary depending on
job requirements. Specifications for length of conduit
runs are guidelines and are not applicable 100% of the
time. (See Technical Specifications on page 4).
Conditions such as debris in conduit and fitting leakage
will reduce the effectiveness of the Blo-Vac system.

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.

c. Conduit Sizes 2-1/2" to 6"

i. Items required are the BV26 seal-off body and the

BV24 seal-off (see Figure 5).

ii. Tag-A-Long or bulk nylon pull line and poly-pull

rope are the types of material suitable for 2-1/2" to
6" conduit. A line carrier is required for each type
pull line or poly rope. Maximum pull line size is
PL232 bulk line (see Figure 6).

Maintenance After Vacuuming Dirt and
Water

1. Release the latches securing the top and center
sections together.

2. Remove the filter bag from the bottom tool storage
section. Slide the filter bag onto the intake canister
located on the bottom of the motor. The filter bag
prevents dust from entering the motor. Dust and dirt
will damage the motor and cause premature failure.

3. Clean the filter bag by shaking off the excess dirt.
Store the clean bag in the lower storage compartment.

4. The Blo-Vac is equipped with a ball float to prevent
water from entering the motor. If the ball float seals the
motor inlet, the motor will sound different from usual.
Immediately shut the unit off. Empty the recovery
section and check the inlet screen for dirt and lint.
Clean the screen and reassemble the Blo-Vac
sections.

Line Carriers

Foam Line Carriers

These are the original line carriers
made of high density poly-foam. As
the line carrier travels through the
conduit it provides a swabbing action
cleaning out water and loose debris.

These carriers have a hook on one end for convenient
attachment of a TAG-A-LONG line package and an eye on
the other end for attachment of pull line. Foam line carriers
are available for 1/2" - 6" conduit sizes (See Figure 7).

The Inflatables® Line Carriers

This patented device has less
friction in the conduit and runs faster
than the foam line carrier. The
flexible nature of the inflatable
carrier allows it to conform to the
conduit diameter. It can pass over
local obstructions that would stop a
foam line carrier. This device can be
vacuumed or blown through conduit. They are
manufactured of tough durable nylon material and are
available in four models covering 3/4"-6" conduit sizes
(see Figure 8).

Missile Line Carriers

Molded of polyethylene plastic,
these low friction carriers offer the
highest speed of the three types of
carriers. These carriers were
developed for the CO2Electric
Blowers and Blo-Vac systems for
use in long and large conduit runs.
If the line carrier encounters a
blockage, the slotted skirt allows the carrier to be pulled
out past joints or steps in the conduit. A hard tug on the
pull line will cause the petals to turn inside out allowing for
easy withdrawal. They are available in 2"-6" conduit sizes
(see Figure 9).

Pull Line

Power Saver™ Line Package

A combination carrier and pull line,
this is the easiest and most
versatile line that can be installed in
conduit. The self contained nylon
line package comes in different
sizes for 1/2", 3/4", and 1" conduit.
It dispenses a line as the package
is blown through the conduit (see Figure 10).

Tag-A-Long™ Line Package

This package is designed for longer
runs and must be used with a line
carrier. The increased package
diameter and length prevents the
package from passing freely through
or around bends in conduit less than
1-1/2". Once attached to the line carrier,
the Tag-A-Long line package
function and operation is similar to that of the
Power Saver (see Figure 11).

Bulk Nylon Line

Unlike the Power Saver and Tag-A­Long packages which dispense a
line as it moves through the conduit
the bulk line package remains at
the conduit entrance and the line is
pulled into the conduit by a line
carrier. The bulk line allows for
longer conduit runs (up to 2200 ft.) and tensile strengths
from 22 to 100 lbs (see Figure 12).

Pull Line

Jet Line stranded PL-series pull
lines are designed specifically for
conduit fishing. These lines are
made of strong polyolefin plastic
that will not rust, rot or mildew.
The patented color coded binder
strand spirals around a bundle of
linear, monofilament that give
almost friction free blowing and
vacuuming. This line, considered
the cadillac of pull line, is
guaranteed to be free of knots
or splices. It is available in
lengths to 6500 ft and tensile
strengths from 100 to 1000
lbs (see Figure 13).

Conduit Measuring Tape

Marked in one foot increments,
this tape is designed to be blown into conduit or duct runs
to determine exact run length for accurate cable cutting
without waste. Available in 3000 ft. rolls (see Figure 14).
