Your "Q.V .P." frame press is unique in that it has a 6" or 24” high top. This special Gusset box top gives over twice the height of conventional frame presses. This means pressing more flat panels at one time or large curved pieces can be pressed in place. In addition, unlike others, it is made with one piece of material with only 8" or 24”of seam at each corner . This means less chance of failure due to seam delamination.

IMPORTANT: Your table top must be flat and non­porous or the frame will leak. Unlike a vacuum bag that only has one or two short sides to seal, the frame press has a long linear perimeter that must be sealed. Do not be concerned if your vacuum pump cycles on and off more often than when using a vacuum bag.
Building the T able Top
A Smooth, FLAT NONPOROUS TABLE TOP IS ESSENTIAL IN GETTING A GOOD VACUUM SEAL. You must spend the time to get it flat for
trouble free frame pressing. The table top should be made from 3/4" or thicker MDF, plywood or particle board. A single sheet is best, however, you can splice 2 sheets together for the larger press. Once the table top is cut to size apply a single sheet of SMOOTH plastic laminate to the top (NON MATTE FINISH). This will make the top nonporous which is very important. If you need to have a joint, apply a bead of Silicone II to the joint and push the second piece into the joint and wipe leaving a slight crown. A slight hump of silicone where the gasket material touches the seam is a better seal than a slight valley below the gasket.
The frame should take about 1 to 2 hours to assemble depending on its size. Building the table can take a day or two.. The following chart is used to size your table top.

THE VAKUUM FRAME PRESS
7/11/12 - Frame Press Instructions.cdr Page 2
The key to the top laying flat is the box frame that supports the top. Straight, dry 2"X6"‘s are recommended. Joint the edges if necessary to make them straight. Make the box as shown in DRAWING A. Use brackets or cleats to hold the table top to the frame box. Use short screws to attach the brackets to the underside of the tabletop. Do not puncture the top surface with a screw as it will cause a leak. This method is used as it allows for shimming the tabletop to assure flatness. Level the top with shims if necessary. This is the most important step in building the table. If it’ s not flat, you could have leakage. Also, if it’s cupped, you could press a curve into your piece. Once the tabletop is completed, it can be used to assemble the frame press.
Applying the SMOOTH Laminate
If you can, purchase a sheet of laminate that will cover the table in one piece. If you have a seam, apply a bead of silicone II along the joint and push the second piece into it, thus filling the seam. Remove the excess. It’s best to leave a slight crown at the joint rather than a slight depression. Where the gasket material comes down on the seal, it will seal better on a slight crown rather than into a depression.
Assembling the Frame Press
Lay the aluminum frame pieces on the table and assemble the joints. Place the steel corner brackets inside the aluminum frame. Slide each joint together. Screw the frame to the connectors with the 1/4-20 phillips head screws using the pre-drilled holes.
Assembling the T op to the Frame:
To assemble the Gusset Top to the frame, elevate the frame 6" or more off the table with blocks with the bottom side (tape) up. This allows you to drop the T op inside the frame. Hold the top in place with several spring clamps. The Top will fit inside the frame. The 2 1/2" flange from the Top should sit on the frame without any bunching or ripples along the frame.
The top is slightly smaller than the frame to eliminate the possibilities of wrinkles or bunching of the material. Hold each corner with a spring clamp and make sure the top is centered.
Note: If you didn't install the frame press when received, you should re-etch the bag top if it's more than one week after shipping date as per the packing slip.. Etch the bag flange (the side that will stick to the tape on the aluminum frame) with PVC pipe cleaner. Etching will give better adhesion.
Remove about 12" of the backing material from the tape from the center of one end only. Press the flange in place as you continue removing the backing from the tape. DO
NOT PRESS THE FLANGE WITH MUCH FORCE A T THIS TIME. You may have to pull up the flange if
you did not center the top correctly . Do the same for the other end. The long lengths should be ripple free, remove the backing material and press the long length in place. Again starting in the center and working toward the end. At this point you have the bottom stuck in place.
Once the top is stuck in place, take a dowel or hard roller and roll around the frame to press the top in place. If you make a mistake in a short length, you can pull the top and reset it. Now remove the paper from the side of the frame and roll the remainder of the flange to the side. Trim excess.
Applying the Foam Gasket T ape:
Apply the foam gasket tape, to the poly top, around the outside edge of the bottom of the frame . Drawing B. Remove about 12 - 18" of backing and start in the center of the front side and work your way around the frame. Make a smooth curve at the corners as in Drawing B. When you come around to the beginning, run the tape to the inside of the Foam Gasket tape just applied, thus making the two rows parallel and tight to each other. This will give you a long joint that will be vacuum tight.

THE VAKUUM FRAME PRESS
7/11/12 - Frame Press Instructions.cdr Page 3
Making the Baseboard
Y ou must make a baseboard or platen for inside the frame. It is similar to the baseboard used in a vacuum bag with saw kerfs 1/8 - 3/16' deep, every 6 to 10" in both directions. This helps improve the seal and cuts down on leakage problems. The baseboard dimensions should be 6" less than the inside of the frame, thus giving a
minimum 3" space Around the frame. Since it lays flat on the tabletop, it can be anywhere from 3/8" to 3/4" thick. You must round all the edges to eliminate all sharp corners. Do not screw the Baseboard to your table top, it will cause leaks, use contact cement or just let it lay in place.
NOTE: The 3" gap between the baseboard and the inside of the frame, helps improve the vacuum seal. Also make sure you push the bag flat on the table around the perimeter of the baseboard when you are pulling vacuum. This will improve the seal and prevent the bag from pulling off the frame.
Installing the VCA6F:
You will need to install a VAKuum Connector Assembly (VCA6F) into your table top as per Drawing D. Drill a 3/4" hole (check the diameter of your VCA6F) in your table where you wish to place the VCA6F. The center of the VCA6F must be below an intersection of the grid lines (saw kerfs) on your baseboard.
Countersink a relief hole in the bottom of your baseboard for the VCA6F bolt head and washers to fit into. Depending on the thickness of your baseboard, the top nut on the VCA6F may come completely through the baseboard. The VCA6F must be slightly below the baseboard. Also, never let the gusset top cover the VCA6F as it can seal the vacuum hole. Always have something on top of the VCA6F (workpiece, piece of board with all edges rounded, etc.).
If you use a thick baseboard, you will need to drill a 1/2" hole through the baseboard that lines up with the VCA6F. Your hole through the baseboard must be at the intersection of a saw kerf (DRAWING D). If you made a mistake and the VCA6F doesn't line up with a grid line on the top of your baseboard, just cut another grid line that connects to the existing grid and goes across the hole.
At this point the Frame Press is ready to use. Use the rubber snap clamps to hold the frame in place. If you use mechanical clamps to hold the frame down, you can have uneven pressure, this will cock the frame and cause leakage. For those who are going to dedicate the Frame Press to the table, attach the hinges.
Attaching the Hinges:
The bottom of the hinges have oval slots. The frame must be able to be squashed down when under vacuum, thus the bottom screws should be loose. Set the frame in place on top of the table with hinges hanging down over the back of the table. When the frame is locked in place, the gap between the table top and the aluminum frame should be about 3/16". Put the screws in at the bottom of the slots, this allows the back of the press to move down when vacuum is applied.
Warning: Do not attach the hinge at a right angle to
the table top. The frame must be able to compress the foam, therefore, it must free to float. If the hinge is on top of the table, the hinge knuckle will keep the foam from compressing and pr ovide a seal
T oggle Clamps:
The toggle clamps are to help create a seal until vacuum pressure generates enough force to maintain its own seal. See diagram on page 7 for placement. See diagram E for installation.
