THE WATERPROOF/BREATHABLE DRYSUIT SHELL USE AND CARE MANUAL A) SROB SPECIFICATIONS O.S Systems, Inc. (OS SYSTEMS) makes two models of its SARR Surface Water Rescue Drysuits that are waterproof and breathable, the Splash-B-SROB (SPLB-SROB) and the Splash-B-SRBEC (SPLB-SRBEC). The SROB is a full featured drysuit having all of the features described below. The SRBEC is the economy version of the same drysuit. Both drysuits are made with the same fabrics, zippers, seals, glue, tape, quality, etc.

LongLife seals are thicker (minimum thickness specification is .026"), more durable than standard recreational seals, and are easily replaced. The instructions for seal replacement are in the Repair Center section below. Additional instructions and helpful hints are available at "www.ossystems.com/repair/repr.htm', and at "www.ossystems.com/repair/seals.html". Cordura/neoprene Wrist Wraps, Ankle Wraps, and a Neck Wrap cover and protect the neck seal, the wrist seals, and the fabric socks.

1. Sizing The first step in wearing SROB is to make sure that your SROB is the correct size drysuit for you. Height is the most important measurement to consider. The MICRO fabric does not stretch. The SROB Drysuit Shell that you select must have adequate room in the ease of the pattern to allow you to reach, bend over, squat, and move around, without feeling any restrictions from the SROB. Do not select a SROB size that is designed for a person who is shorter than you.
PAGE 5
Insert your left hand and arm into the left arm of your SROB. Pull the left shoulder of your SROB fully over your left shoulder, extending your left arm down into the sleeve and to the wrist seal. Hold your straightened fingers together so that they form one single unit pushing through the wrist seal.

air back into your SROB by slightly opening the neck seal. your own comfort level. Find Determine your final comfort level, and once again, set the crotch!! Additional burping may be done when you enter the water. Submerse yourself up to the level of your arm pits. Bring your arms in close against your body. With one hand, reach up and vent your neck seal until sufficient air has escaped.
PAGE 7
fabric can immediately transmit the heat you generate, but the SROB will rapidly catch up once your activity level slows down. Remember that the rubber neck and wrist seals are not breathable. Sweat will build up under those seals. Rubber seals are very susceptible to punctures and tears. All drysuit fabrics must be kept unpunctured to be dry. The SROB has reinforcing pads, Wraps, and covers in critical areas to protect the SROB fabric. See the Repair Section of this Manual for repair procedures. 4.

1. Inspect your SROB (before & after) Each Use (a) Neck & Wrist Seals Look at the outer edge of all latex seals. Look for a V notch starting that can lead to seal splitting. Look for cracking or checking in the latex material. Look for a soft/gummy feeling to the latex. If you find ANY of these problems do not use the suit. the seal. Replace If there are any areas where the latex is lifting slightly from the SROB, apply a small touch of PB-300 to the area and press the seal back down to the fabric.
PAGE 9
Now turn the suit right side out and inspect for holes, punctures and tears paying special attention to the bottom of the attached socks, and patch as needed. Inspect the pockets, zipper covers, Neck, Wrist and Ankle Wraps for signs of wear or separation from the body of the suit. If you find any of these problems do not use the suit until it is repaired. 2. Inspect your SROB every 30 days Conduct the same inspection of your SROB every 30 days, even if you have not used it.

wrist is a full 1" tube (more sealing area = more watertight). This larger sealing area spreads out the squeeze pressure that makes the watertight seal, eliminating any single point contact and enhancing user comfort. OS Systems recommends and uses bell style neck seals. The bell style neck seal comes with sizing rings on the upper cone portion of the neck seal. These rings can be trimmed to accommodate different sized necks, within limits.

1. After every usage, wash the latex seal inside and outside with a mild soap and warm water solution (if available) to remove all contamination that comes from body oils, pollution, lotions, etc. 2. Apply UV Tech to the cleaned latex both on the inside and on the outside of the seal. 3. Store the suit rolled up in its bag to minimize the airflow around the seals. This allows the UV Tech to better protect the latex. 4. Apply UV Tech to all seals again prior to using the suit.

only 6 hours at a time. Test fit the seals after the first 6 hours. Repeat the 6-hour sessions as needed until the seals are comfortable. Make sure that you have applied UV Tech to the latex prior to stretching. OS SYSTEMS manufactures 4 sizes of neck seals and 3 sizes of wrist seals. Make sure that you have the correct size seal installed on your drysuit BEFORE you start any stretching of the seals. WARNING!! Never use a seal that is so tight that blood flow is restricted to the head or hands.

(b) Methyl Ethyl Keytone (MEK) Methyl Ethyl Keytone (MEK) is an organic solvent. MEK is used in many plastics, including the polyurethane in the PB-300 adhesive and the waterproof/breathable membrane in the MICRO fabric. MEK is the best solvent to clean oils from the areas to be glued, to clean old PB-300 from the area to be glued, and to thin the PB-300 used to glue seals or MICRO fabric. NOTE: MEK does dissolve polyurethane.
PAGE 14
All seal holes and punctures are patched from the outside of the seals. Cut a patch of appropriate size from latex rubber material that is supplied. The patch should be round or oval shaped, NO CORNERS THAT CAN CATCH AND PULL UP! Using MEK, clean the area of the rubber seal and the rubber patching material, where the PB-300 is to be applied. Wipe the areas dry with a CLEAN absorbent material.
PAGE 15
To test an SROB Drysuit, first fully close the relief zipper. Then turn the SROB inside out and reach through the neck to fully close the front entry zipper. There are two basic methods of closing off the wrist and neck seals, plug and secure, or fold and clamp. To plug and secure, insert two small cans, or sand filled bottles (cups filled with sand and sealed with duct tape work well) into the wrist seals.

long. Cut that piece lengthwise so that you will have two pieces approximately 1.00 x 1.50 inches. Roll each piece length wise to create a small tube that has adhesive all around the outside. You will want at least three of these duct tape tubes to place on the mold, and under the sleeve fabric, at even points near the furthermost edge of the sleeve.
PAGE 17
The original neck seal (what is left after trimming) should be centered on the plate, with the rubber facing up. Wipe the top of the base of the new neck seal, and the exposed band of rubber on the old neck seal, with MEK. Wipe both dry with a clean (lint free) cloth. Apply one coat of PB-300 adhesive to the original and new neck seal, where new seal will overlay the original seal. Wait for 3 minutes, and apply a second coat of PB-300 adhesive to the same two parts. Let them sit for 2 minutes.
