Your vac rac and its parts are stored in the OPTIONAL Cotton Carry Bag

It is very important that the latex vac rac bag air tight zipper be stored with no kinks or sharp corners. To keep nice round corners when folding the bag, use the vent pipe to keep a rounded corner for the zipper. Store the bag with the zipper fully open because material fatigue from a closed zipper will lead to premature wearing out and air leaks in the zipper. Never weight down the zipper, keep it on top.

The 6 plastic pipes can be tethered with 2 Velcro straps (not included) for easier storage.

6 pieces of 2" perforated plastic pipe forms the frame placed inside the vac rac latex bag.

Assembly: layout the latex bag on a firm continuous surface. Do not try to use a bed, damage to the vac rac bag will result. Use a floor or large padded surface that supports the entire vac rac bag. It is overall about 45" x 84"

Insert the end tubing to each end of the latex bag.

Assemble the valve a shown  note that the nut on the valve points to the inside of the vac rac figure B.

Insert the valve in the inner top pipe with the tee connector figure A through D

Fit the top pipe with the valve into the vac rac sheet and gently pull the vlave asembly through the hole in the vac rac sheet and ensure the latex sheet i not creased and ha a smooth fit around the protruding vlave parts figure E.

Slide the foot pipe (plain - no elbows)into the foot of the vac rac (assembly shown on top of the vac rac for ease in viewing)

Reach in the vac rac sheet to place the far bottom side pipe (with elbow) and without pinching the latex sheet insert the end pipe into the elbow. Do the same for the side piece at the zipper that will fit into the foot pipe as shown Figure G.

Now add the far side upper side pipe and fit into the top pipe (shown in Figure H on top of the vac rac sheet for ease in illustration). And finally add the zipper side upper pipe and fit into the top pipe Figure I and J. Again care is needed not to pinch the sheeting. In the assembly the top side pieces should have the slding coupling facing up located in the middle of the vac rac. Finally assembel the upper and lower side pipes and slide the coupling into the lower pipe creating a stronger joint that resists coming apart under vacuum. (Note the side pipe with coupling can be used in the lower upper side)

Have the user get in the bag, best to have them sit with feet in the bag then lower them selbvves into the bag with hands in front of their face so they can locate the breathing hole  easily. Then adjust the breathing tubes or masks for comfort.

Note: the users including attendents, should not be wearing any jewelery or metal items that may tear the latex. Sharp finger and toe nails need to be trimmed or covered. Using boots or heavy helmets, gas masks, leather gear can cause damage to the sheeting. We strongly suggest socks or latex items be used as body coverings for hands and feet regardless.

Check carefully that the latex bag is not curled, or, twisted or caught in the pipes. Frequently on entry pipes may separate and nee to be refitted with the person inside.

Check the occupant for safety signals, and clear any airway obstructions.

Close the zipper leaving with about 6" remaining from the end. Let the occupant get accustomed to the space  when they are comfortable close the zipper fully.

Vacuum and the outlet valve

Using a vacuum source, gently and slowly cup the vacuum hose near the outlet valve. Do not place the vacuum directly over the valve to lim,it the stress on the vacuum. The strong suction, if too fast can cause rapid vacuum of the bag that may leave the occupant fearful. Take your time.

Check the occupant comfort. We suggest several minutes be provided for the occupant to acclimatize to the sensations. When suitable, close the zipper completely. The bag is airtight unless the occupant exhales through their nose. Hoods or similar devices can limit this air leak.

Slowly suck out air, a little at a time, monitor the occupant comfort. Once the vacuum intensity desired has been reached, you can shut off the vacuum source.

One suggested set of items to use to make the airway continuous without air leaking into the bag.

/tolp000139 copy.jpg

Option: Vacpac Hood with mouthpiece - $125.00

An extra large hood, black colour, mouth opening only,

Mouthpiece fits into opening in the hood. If silicone or other lubricants are used, the mouthpiece may be difficult to retain in the hood or vac rac bag.

The mouth piece is then pulled through the opening in the Vacpac bag airway opening. As air is removed the hood will fit tightly over the head, air exchange is only through the breathing tubes or mouthpiece. The risk of the mouthpiece separating from the hood or vac rac bag is possible, be aware of this possibility when moving the head or making sudden movements.

To add air slowly to the bag open the zipper, At any time the zipper can be opened  fully to restore ambient pressure.

Danger - This is a High Risk Experience

Please read carefully

At no time should the occupant be left unobserved by one or more attendants. Always have the attendants stationed at the side of the vac rac bag to open the zipper instantly if a situation occurs.

There are many risks associated with restriction from suction, Caught-In-The-Act recommends that the participants be trained by knowledgeable and experienced vac rac users. Sources on the Internet, training seminars, books and other resources may help inform the users. Caught-in-The-Act offer their products as novelties only. Please review your risks and responsibilities in the use of any product that may be used in a situation where the partial or complete loss of control by a user may occur. Under no circumstance should the vac rac be used without attendants present (solo experiences).

Care of this product.

Latex sheets can catch on sharp objects and rip, be especially cautious when washing and drying the bag. Protect the latex from sharp finger nails and toe nails. Do not use with any metal devices or jewelry that may come in contact with the surface. If you use a silicone shine as protectorant extra care is needed as the sheets will tend to stick to the occupant. excessive stress can cause a tear. We highly recommend using powder on the bag surfaces inside and out. Wash and dry thoroughly as per the latex FAQ links. The airtight dry suit type zipper does not require frequent lubrication. However, if it is hard to open or close, use dry suit zipper lubricant available at sports stores and dive shops. Do not kink, bend sharply or pull on the zipper components, which could result in damage to the zipper. Store the zipper in the open position to prevent premature wear and leaks. Make sure the latex is washed after use, dry well allow at least 24 hours to dry on each side (inside and out), then powder and store loosely in a storage bag. Always store in a cool dark location.
