TOOL LISTING
Depending on the installation, the use of the following tools
may be required:
Wire strippers, 1/4’’ and 1/2” drill bits, utility knife, putty knife,
2½’’ hole saw, keyhole saw, hammer, cold chisel, level,
flashlight, drill, electrical tape, Phillips no. 2 screwdriver,
wrench, hacksaw, tape measure, safety glasses.
Power tools are recommended to make the installation proceed
quickly. A mask and gloves should be worn when cutting
ducting and using glue.
WORKING WITH PLASTIC TUBING
CUTTING TUBING
Measure the length of tube needed. Allow 5/8” of tubing for
inserting into fittings and 1½” for placing into flexible tubing.
Cut the plastic tubing with a hacksaw, ensuring that the cut
is exactly square. Use wire cutters or tin snips to cut flexible
tubing, 8” lengths of flexible tubing should not be cut.
Use a small knife or steel wool to remove any burrs from the
inside of the tube.
Use a file to slightly bevel the outside of the tube so that it will
easily slide into the fitting. Use steel wool or a light grained
sandpaper to buff the surface of the tube which will be glued.
MAKING A JOINT
Insert the tube into the fitting,
aligning both parts as they will be
installed. Mark the tube and the
fitting to quickly realign the joint.
Apply cement in an inch-wide
band to the outside of the tube.
Insert the tube into the fitting with
the alignment marks a quarter
turn apart, and then quickly push
and turn the fitting to align the
marks and spread the cement.
Allow 1 minute for the joint to dry.
CEMENTING FLEXIBLE
TUBING
Ensure the ends of the flexible tubing are even. When joining
flexible tubing to plastic tubing or to an inlet mounting plate,
apply cement to both the inside of the flexible tubing and the
outside of the plastic tubing or mounting plate tubing ring.Twist
both pieces while joining them to evenly spread the glue. Allow
5 minutes for the cement to set in flexible tubing.
SECURE WIRE TO
TUBING
The low-voltage power wiring is
run along with the tubing. Use
electrical tape to secure the
wire to the tubing. Tape the wire
approximately every 12" to 18".
MAKING THE WALL INLET CUTOUT
The wall inlet should be located 18” on-center from the floor
and directly in line with the attic or basement inlet tubing hole
previously drilled in the wall plate or header. The wall inlet
cutout must be exactly 378” high by 278” wide.
ATTACHING THE INLET MOUNTING PLATE
(V144)
Reach through the inlet hole and locate the inlet tubing. Pull
the flexible tubing through the inlet hole and remove the
low-voltage wiring from inside the tube.
Remove the nail flange
from the inlet mounting
plate (see illustration at

both the inside of the
flexible tubing and to the
outside of the mounting
plate’s tube ring. Insert
the mounting plate’s
tube ring in the flexible
tubing and twisting the
pieces as you join them
to spread the cement, and align the mounting plate in a vertical
position.
Now, strip the ends of the two low-voltage wires, and then
connect the wires to the screw terminals on the back of the
inlet cover. When the wiring is complete, assemble the inlet
cover to the tube guard and mounting plate.
COMPLETING
THE INLET
ASSEMBLY
Once you have attached
the mounting plate to the
flexible tubing, pull the
low-voltage wire through
the top wiring hole in the
mounting plate.

Open the wall inlet cover and insert the end of the hose into the
inlet to turn on the vacuum.
For non-switched hoses, inserting the hose automatically turns
on the power unit; removing the hose shuts off the power unit.
Some hoses have switches which can be used to activate
power unit. The ON/OFF switch located on the power unit
needs to be kept in the OFF position.
As you vacuum, dirt and dust are carried to the power unit
where they remain in a bag or in the debris pail (according to
the power unit model).
Use the cleaning tools as you would for any other vacuum
cleaner. Avoid picking up very large debris or lengthy as these
kinds of objects may become lodged in the hose or tubing.
WHEN TO CHANGE BAG* OR EMPTY
DEBRIS PAIL
With a 6 U.S. gallons (22.7 liters) capacity, under normal
conditions the bag/debris pail requires changing/emptying
approximately twice a year. If the bag/debris pail is full, you will
notice a reduced suction from the system. Unless this loss of
suction is caused by a blockage in the system, changing the
bag or emptying the debris pail will solve the problem.
NOTE: Even if not filled to capacity, if the bag seems tightly
stretched when removing the debris pail, changing
the bag will prevent it from tearing.
* Only BQ1 unit is equipped with a disposable bag (391C).
HOW TO EMPTY DEBRIS PAIL
(BQ2 AND BQ3 POWER UNITS ONLY)
To empty the debris pail, release both latches on sides of the
unit by pulling out and then pushing up. Holding the pail by the
latches, lower it from unit. Carry pail to trash receptacle and
dispose of debris. Put the pail back in its place.

TROUBLESHOOTING GUIDE
PROBLEMS POSSIBLE CAUSES POSSIBLE REMEDY
1. Loss or decrease of
suction occurs. • Debris pail or disposable bag is completely full.
• Debris pail gasket damaged or missing.
• Obstruction in the hose. A blockage in the hose
can be determined by inserting the hose into
any wall inlet and, while power unit is running,
check each additional inlet for normal suction
by holding the palm of your hand over the
open inlet. If normal suction is felt at all other
inlets, insert the hose into a second inlet. If the
blockage still exists it is located in the hose.
However, if the blockage does not occur when
the hose is changed, the blockage is probably
located in the tubing system leading to the
original inlet.
• Obstruction in the tubing system inside the
walls.
• Permanent filter or disposable bag torn.
• Wall inlet cover not properly sealed.
• Exhaust tubing or vent clogged.
• Change the disposable bag or empty debris pail
as described on page 10.
• Replace the debris pail gasket.
• Disconnect the hose from the wall inlet and
insert a blunt instrument into the hose —
slightly smaller in diameter — such as a flexible
garden hose. Push the garden hose through the
cleaning system hose until the obstruction has
been cleared.
• Insert hose end into any inlet to make power unit
running, then place the palm of your hand over
the opposite end of the hose.When you can feel
the suction increase, hold your hand over the
hose end for a few seconds and then quickly
remove your hand. This procedure repeated
several times should clear the obstruction. If the
blockage is not cleared, contact your nearest
Service Center.
• Clean the interior or the unit and install a new
permanent filter (or disposable bag).
• Check all wall inlet covers to be sure they are
closed and sealed tightly.
• Inspect and remove any blockages.
2. Power unit does
not start, or stops
suddenly.
• Defective inlet. Check other wall inlets.
• Power unit internal circuit breaker has been
activated (the reset button is popped up).
• Blown fuse or tripped circuit breaker on house
electrical panel.
• Defective hose.
• Power unit overcurrent protector has been
activated.
3. Power unit runs
continuously when
the hose is removed.
• The unit power switch is in ON position.
• An electrical short has occurred somewhere in
the system.
• Set the unit power switch to OFF position.
• Perform a complete check of all wall inlets and
power unit low voltage control lead connections.
Contact your authorized Service Center.
• Replace defective wall inlet.
• Push on the circuit
breaker reset
button located on
the left side of
the power unit. If
this button pops
up again, contact
your authorized
Service Center.
• Replace fuse or reset circuit breaker on house
electrical panel.Ensure the circuit is DEDICATED
to the central vacuum unit, meaning that there
is no other electrical device connected to the
central vacuum unit circuit.
• Some brands of house panel breakers may be
more sensitive to startup current than others (for
example, Square D brand). Correct the situation
by changing the breaker with an “HM” type of
the same AMP rating.
• Replace hose as required.
• Unplug the power unit, wait at least 15 minutes
and plug the power unit back in.
