    This manual is intended to help acquaint you with the basic features and operation of the Atomic BC1, but it is impossible to provide you with all of the information and the hands-on training you need in order to use the product in a safe and enjoyable manner.

  • Page 12: Attaching The Low Pressure Hose With Quick Disconnect To The Regulator

    The low pressure hose and quick disconnect is usually routed over the left shoulder where it follows the corrugated hose of your BC1. The low pressure port plug is removed by unscrewing with a 5/32 (4mm) hex wrench. Install the low pressure hose with quick disconnect into the port of choice and snug up with a wrench.

    High-pressure port Low pressure quick disconnect Low-pressure ports Ratcheting CAM-LOK tank band Yet another Atomic design exclusive. You will be amazed how easy this is to use, and how securely it holds your tank in place. The concept is similar to the bindings on ski boots and snowboards. The ratcheting band quickly adjusts to accommodate a variety of tank sizes and the over-center buckle locks everything tightly in place with an easy push.
  • Page 14: Placement Of The Band In The Backpack

    The tank band will fit all popular tank sizes up to 8" (203mm) diameter. The BC1 is shipped from the factory with the band in the position for a standard 80 Cu ft. (10 liter) tank. The band assembly does not need to be changed to accommodate different size tanks.
  • Page 15: Tank Buckle Operation

    Tank buckle operation The tank band is attached to the buckle, which is composed of 4 parts. The band itself, the link which attaches the band to the cam handle that opens or closes the buckle, the ratchet frame which is connected to the Ratchet Frame cam handle, and the ratchet lock that is used to adjust the band tension.
  • Page 16 To remove the band from the tank, lift open the cam handle. Depress the ratchet lock to loosen the band. You can loosen it just enough to lift off of the tank, or pull the tank band completely out of the buckle. Lift cam handle.
  • Page 17: Ez-Lok Integrated Weight Release System

    In the event of an emergency you can choose to jettison one or both weight pouches, thereby creating more buoyancy. The weight pouches can be easily reloaded into the BC1 pockets while you are wearing the BC for use during training.
  • Page 18: Loading The Ez-Lok Weight Pouches

    The weight pouches can be filled with either hard “block” weights or lead-filled mesh “soft” weights. Regardless of the type of weight being used, fill each pouch with equal amounts of weight so the BC1 will be balanced in the water.
  • Page 19: Securing The Weight Pouches Into The Bc1

    Securing the weight pouches into the BC1 Each weight pouch will fit into either left or right weight pocket on the BC1. With the fabric side of the pouch facing out, slide the pouch into the pocket and push it in until you hear or feel it “SNAP” or “click” into place. To confirm that it is locked in place, tug on the small webbing test tab on the front of the pocket.
  • Page 20: Tips For Using The Ez-Lok Weight System

    You may choose to install the weights before donning the BC1 or afterwards, whichever works best for you. The weight pouches will load and unload easier if the BC1 is not fully inflated. The weight pouches can be easily removed in the water or swim step and handed to someone on board to assist in getting out of the water.
  • Page 21: Non-Releasable Trim Weight Pockets

    Don’t pull on the handle to test it or it will release. Non-releasable trim weight pockets On the rear of the BC1 you will see two pocket flaps for non- releasable weights. Each pocket holds up to 5 lbs. (2.2 Kg) - 3 lbs. on the small size. These are used to ‘balance”...

  • Page 23: Pre-Dive Inspection

    Pre-Dive Inspection You should inspect your BC and its associated equipment before leaving for your dive destination. If in the event you find something that needs attention, this could provide time to remedy the issue and perhaps avoid the disappointment of having to cancel a dive after you have reached your destination.
  • Page 24: Accessories

    Accessories 10 D-Rings The BC1 has a total of 10 triangular shaped D–rings in various locations to accommodate a variety of possible accessories. Heavy duty 1-1/2" 316 Stainless Steel rings with Titanium PVD coating are located on the shoulders and top edge of the pockets.
  • Page 25: Accessory Pockets With Sand-Resistant Zippers

    Underneath the arms and directly over the weight pockets are the zippered accessory pockets. They are in an easy-to- access location and maintain their volume even when the BC1 is inflated. The zippers are water resistant and protect the teeth from sand and debris.
  • Page 26: Fitting The Bc1

    Fitting the BC1 The BC1 comes in a variety of sizes to fit a wide range of men and women wearing a variety of exposure suit types. All the straps have adjustable length sliding buckles. Once you have selected the basic size appropriate for you, the waistband can be further adjusted if too long or too short.
  • Page 27: Waistband Adjustment

    Both the cummerbund and the overlapping webbing waist strap can be shortened or lengthened. To change the cummerbund length, place the BC1 backpack down and open it to expose the lumbar pad. Fold back the lumbar pad and you will see the end of the cummerbund looped through...
  • Page 28: Lumbar Adjustment

    The plastic lumbar plate has about 1-1/2" of vertical adjustment. The plates are factory set for the specific size of the BC1. However, they can be repositioned. Grasp the lumbar pad and, using a ¼" hex wrench, loosen the lower back plate bolt just enough until you can slide the plate up or down.

    BC1 and depress the large deflation button. If you are face down, the inflator will be lower than the air bubble in the BC1 and it will not vent. Overpressure relief valves: There are 3 combination overpressure/dump valves on the BC1.
  • Page 30 BC1. A cable inside the inflator hose is attached to the combination overpressure/dump valve in the module where the hose is attached to the BC1. Do not pull or stretch the inflator hose unless you deliberately intend to vent the BC1. The valve will open without excessive force and it only requires less than one half inch of travel.
  • Page 31 On the back of the BC1 on the lower right side is a manual dump valve with a short cable and anti-floating pull knob. Pull this knob to vent the BC1 if in an inverted upside down position. CAUTION The proper function of either overpressure relief valve is vital to prevent damage to the BC bladder.
  • Page 32: Post Dive Cleaning

    Leave the zippered weight pouches and accessory pockets unzipped until dry. 4. Fill the BC1 bladder about 1/4 of the way with clean fresh water through the oral inflation mouthpiece. Inflate the BC and shake to rinse inside the BC. Hold the BC upside down, depress the deflation button on the oral inflator, and drain the water out of the bladder.
  • Page 33: General Care

    6. Routine Service Checks It is highly recommended the BC1 be checked annually by an authorized dealer for air leakage, condition of the hoses and general operation. This process generally is a simple inspection and can prevent your having to cancel a dive due to an operational problem you may not recognize with your BC.
  • Page 34: Warranty

    Atomic Aquatics shall not be liable for loss of use of this product or incidental or consequential costs or damages incurred with the use of this BC1 Buoyancy Compensator. Some states do not allow this exclusion so the above may not apply to you.
