VAK-MATIC INSTRUCTIONS

07/27/10r2 - VAK-Matic Instructions.cdr

The VAK-MATIC system is designed to turn the VAK PUMP
on and off automatically at a predetermined settings. This
has the advantage of only using compressed air when
required (normally less than 4 minutes/hour after the original
evacuation). This, of course, reduces the load on the
compressor. Also, the bag can be left unattended without fear
of a loss in pressure.

A porous Baseboard (BB) will cause the VAK-MATIC control
box to cycle on/off more frequently in the beginning due to the
air being released from the material.

1. Connect the compressed filtered air line to the air input (a
standard 1/4"NPTF thread) on the right front of the box.
Connect the V AK hose to the hose barb on the left front of the
box.

2. If your VAK-MATIC does not have a regulator, your
connecting air line should be set at 85 - 90psi when the unit is
running. With the built in regulator, adjust it to 85 - 90 p si.

Without a regulator do not exceed 100psi while the unit is
running on the compressed air line as it will prevent the
solenoid air valve from operating and cause it to not shut off.

3. Press the rocker switch to VAK BAG, block the vacuum
hose with your thumb. It should instantly go to 23-25"Hg and
shut off. If so go to section 4.

The vacuum level of the VAK SENSOR is factory set at
approximately 25"Hg, however , for various reasons (altitude,
line pressure, line volume, leaks, etc.) you may not achieve
this level. If the VAK PUMP does not shut off, you need to
adjust the V AK SENSOR or air regulator.

With your thumb over the hose, turn the rocker switch to V AK
Bag and turn the air regulator (black knob on right side)
clockwise to increase the pressure up to a maximum of 100
psi. If the unit still does not shut off, with the selector switch
set at "V AK BAG," slowly turn the vacuum switch adjustment
screw counter clockwise until the pump shuts off. This will be
the setting for your conditions. Block and unblock the vacuum
hose several times to assure that the setting is correct.

NOTE: Starting additional air tools, while operating the VAK
PUMP, could cause a pressure or volume drop, thus
decreasing the performance of the pump. This could also be
a cause of the pump not reaching 25"Hg.

baseboard with a piece of wood to prevent the bag from
sealing the the vacuum hole. An 8' VAK bag should take
about 1 to 1.5 minutes (Super Pro VM6) to reach 25"Hg and
shut off. With the VM4 (Pro) it should take about 2 mins. They
could take longer if your BB is porous and giving off air or
moisture as the vacuum level increases. The pump will shut
off at 25"Hg (or your setting per section 4). When the vacuum
level falls 4-5"Hg below maximum setting, it will cycle back on.
If short cycles of 30-60 seconds continue after 10-15 minutes,
check for leaks per the section: "What To Do If It Leaks" in the
bag instructions.

Continuous short cycling can occur if residual air is trapped in
the bag. This can be caused by your set-up inside the bag or if
you rolled up the bag to make it shorter or narrower . If this is
the case, start the controller on V AK KLAMP and let it run for 1

- 2 minutes longer than it would normally run under V AK BAG.
Then put the switch back on V AK BAG . If you have a vinyl bag
and only want to use a small portion of it, purchase another
end closure to properly close off the unused portion of the
bag.

CAUTION:
Do not blow out the VAK-MATIC vacuum line with
compressed air. You must open the box (Disconnect the
electrical connection first.) and disconnect the VAK Sensor
vacuum line. Compressed air will damage the V AK Sensor.

Never use the V AK-MATIC for vacuum clamping (vacuum jigs
& fixtures with the switch set at V AK Bag. For safety reasons,
always run the pump continuously for vacuum clamping.

TROUBLESHOOTING

01/11/2006r2 - VAK-Matic Instructions.cdr

If the unit does not shut off, it could be the solenoid, the
on/off switch, too high of an input air pressure or the
V AKuum Sensor.

Solenoid:

If the unit is unplugged from the wall (the air hose is still
attached) and you can hear air hissing inside the box,
the solenoid is still open. Make sure the air pressure is
under 100psi or it will not close. More than likely it has
dirt in it from the air source. Open the box and locate the
solenoid that is a 1 inch round cylinder. On top of the
cylinder is a nut. Remove the nut and slide the coil off,
keep track of the washers and how they fit. Just below
the nut threads, on the shaft, is a 1/4" length of shaft that
you can apply pliers to and loosen the shaft. Be careful
when you remove the shaft as there are a spring and
plunger inside. Clean the insides, it only takes a small
speck of dirt to keep the solenoid open. Reassemble
the solenoid.

ON/OFF Switch:

If the switch lights up but only works on V AK Bag or just
VAK Klamp, it could be a loose wire. Unplug the unit
from the wall and open the box. Tug on each wire to see
if any are loose. Recrimp if any wire comes out of its
clip. Also, blow out the switch with an air gun. Blow
between the rocker and the black bezel. This may clean
out the contacts. If only one side works after blowing
out the switch (VAK Bag or VAK Klamp), the switch
should be replaced. As a temporary fix you can swap
the leads, to get the function you need, to work. Just
swap the leads from end to end, leave the two center
leads in place.

V AK Sensor:

The sensor has an average life of more than one million
cycles and rarely fails. Sometimes the sensor does not
shut off as it gets to the higher vacuum level or it takes a
tap on the sensor for it to shut off. This may not be the
sensor malfunction. It could be caused by: not enough
air pressure to get it to vacuum level, a small leak in the
system that the V AK Pump cannot overcome at the high
vacuum level or the sensor is set too high.

and cover the barb. Turn the switch on to V AK Bag and
if it gets to vacuum level and shuts off, the sensor is OK.
The problem is probably a leak in the bag. If it does not
shut off, turn the sensor counter clockwise to reduce the
shut off point. If it shuts off, the sensor is OK.

Problem:

Pump cycles on and off rapidly and the time between
cycles does not decrease after the first few minutes.

Solutions:

Check to see if sawdust is in the line. The box must be
opened (unplug first) and the 1/2" I.D. line which
contains a check valve (1/2” long black piece) may have
a chip in the check valve. Remove the hose and blow in
from the black end, if air flows it is stuck or broken. If
OK, replace and be sure the end with a small red plastic
piece is facing towards the bag.

Important - To remove the line from the VAKuum
sensor you may have to cut it off. Trying to pull it of f the
sensor may cause the barb to snap.

If you are using a small amount of steel wool as a filter in
the VAKuum line (outside the box), it could be blocked
with sawdust and chips. This will cause cycling.
Remove the steel wool and sawdust and replace the
steel wool. Do not pack the steel wool densely .

Check the bag at the V AKuum Connector Assembly. If
the VCA is not covered by the workpiece, the bag is
being sucked into the opening and blocking the vacuum
line before the bag is fully evacuated. Cover the
opening with a piece of stock (3“x3”x1/4” round over
edges) to eliminate this problem.

If you have an ALL-in-ONE System, check the valve in
the back. For veneering, the valve should be off. For
clamping with jigs, it should be open.

For regular VM's or if you have a VM10/15FS, you will
have check valve inside the box. Open the box and
remove the hose with the check valve and check if
operating properly as instructions above..

Check the air pressure while it's operating, make sure
it is 85 to 90 psi. Remove the vacuum hose from the box
