INSTRUCTIONS FOR ASSEMBLING
THE VAKUUM BAG
05/18/05 - Bag Instructions.cdr REV5
BASEBOARD
The purpose of the baseboard (BB) is to provide a base for
the workpiece to lie on. It should be a minimum of 6“
shorter and 4” narrower than the bag dimensions. This will
allow for materials to be put inside the bag without
excessive stretching. The BB should be made with any
ridge material that is flat and a minimum of 3/4” thick. It’s
also best to have a non-porous material that will not absorb
glue or outgas when under vacuum. Melimine coated
particle board is a good material for the BB.
The top of the BB needs saw kerfs or channels cut every 6 -
8“ in the length and width. These channels permit air to be
evacuated when the top of the bag is flat against the BB.
Round all edges and corners and remove any splinters. If
you use a narrow blade saw (.030”), you can use the
basebaord as the bottom caul. Always test to make sure
that the veneer does not show impressions from the kerfs.
This can save time and money from not having to make
different size cauls.
Next, a hole is needed for the VCA(6) or vacuum connector
assembly. At an intersection of two channels that is at
least 6“ from the edge of the bag, drill a 1-1/8” dia. hole
5/16” deep (1” dia. For VCA) Then drill a 3/4” dia. hole
through the BB (5/8” for the VCA). Make sure the exit hole
is clean and splinter free. Remove the nut, two metal
washers and the rubber washers from the VCA. Push the
brass piece through the BB so that the bolt head is in the
recessed hole (should be slightly below the top of the BB).
Place one of the rubber washers over the stem and snug it
up to the bottom of the BB. See drawing A. Slide the BB
into the bag, the rubber washer holds the brass stem in
place.
Position the BB in the bag and cut an X, in the bag, (use a
sharp knife, especially on poly bags) over the hole in the
barb and then push the bag down to the rubber washer.
Trim the excess bag material, do not over trim as it should
be a snug fit.
Place the other rubber washer over the stem, then the
large metal washer followed by the lock washer and the
nut. With one hand hold the bag to prevent it from twisting
and sung up the nut. Do not over tighten.
Turn the bag/BB over and attach the pump per the
assembly instructions. It is suggested that the bag be
placed on cardboard or a mat to prevent it from picking up
splinters.

CLOSING THE BAG
Place the plastic rod about 2“ from the open end of the bag.
Fold the open end over the rod once, leaving about 1”
overlap. Snap the C-Closure over the bag and rod.
Sometime it will help to put spring-clamps on the closure to
keep it from opening when it’s under tension. This can
occur when there are large objects in the bag.
TESTING THE BAG
Power the pump, the vacuum gauge should read between
23 and 25“Hg (inches of mercury) when the automatic units
reach’s vacuum level and shuts off. The unit will cycle on
and off as it needs vacuum. If the on/off cycles are short
(less than 2 minutes) and do not get longer with time, then
you have a leak or you did not cover the vacuum hole.
05/17/05R3
If your workpiece does not cover the vacuum hole, place a
piece of stock (3“x3”x1/2” round all edges) over the vacuum
hole. This will prevent the bag from being sucked into the
hole and blocking the air flow before the bag is totally
evacuated.
