Ready for your first dive using the SCUBA breather!
We, and any other trained diver would strongly suggest that you
obtain, read, and understand a good basic SCUBA Diving Book
before making your first dive!
Find a suitable location for the SCUBA Breather; this should be a very easy task. Any location near the dive site where the unit is out of the way as a tripping hazard is suitable. Once a good flat stable location is found, steps should be taken to assure that the unit does not get dragged into the water by pulling on the regulator pressure line(s) or tripping over the unit.
Securing the dive unit container to a post or unmovable object is recommended.
The entire unit can be mounted/set in any configuration except upside down.
Important step: unravel the blue pressure hose and lay it out, assuring there are no kinks or knots in the line.
The storage container lid must be kept open anytime the unit is in operation. With the lid closed, the compressor motor will overheat because of a lack of air circulation.
Power-up the Dive Unit
Using a good quality industrial style 14 gauge extension cord not exceeding 50 feet, for getting the power to the unit is totally acceptable. If using an extension cord over 50 feet, a 12 gauge cord is necessary, otherwise the motor may overheat due to the voltage drop through the extension cord.
The entire unit can be mounted/set in any configuration except upside down.
Note: We do not recommend using a Ground Fault Interrupter (GFI) with the SCUBA breather. GFI's are too susceptible to tripping (shutting down the power); this is not a condition you would want when you are making a serious dive in the ocean, a deep dive, or performing work underwater. The exception to this guideline is when you are set up in a very controlled and relatively safe environment such as a Swimming Pool. The SCUBA breather is an exceedingly reliable machine and there is very little that would cause an interruption to breathing air - loss of electrical power to the compressor is the one exception. However, if there is a loss of electrical power to the Dive Unit, the diver will NOT experience an abrupt interruption of breathing air - this is where the Unit's Air Storage tanks take over. The diver will instead experience an ever increasing labor in breathing as the air in the Storage Tanks is being depleted. The diver should be able to recognize this and return to the surface to investigate the problem.
Hooking up the Regulator Hoses:
DIRT AND DUST IS THE ENEMY OF PRECISION PNEUMATIC EQUIPMENT!
Before attaching the Regulator Hose Quick Disconnect coupling(s) to the Manifold, follow these steps to assure there is no residual dirt or dust in the fittings:
Start the compressor by turning the AUTO/OFF switch to ON,
Allow the unit to pump-up to full operating pressure,
OPEN then CLOSE each breathing air outlet isolation valve quickly to allow a blast of compressed air to blow out any accumulation of debris that may be inside the Male portion of the Quick Disconnect fitting,
Then, blow out the Female body of each Quick Disconnect fitting by holding this fitting close to the the Male fitting - OPEN then CLOSE the air outlet isolation valve once again allowing a blast of compressed air to blow out any accumulation of debris that may be inside this fitting,
You can now be assured there is no dirt or dust in the entire Breathing Air supply line.
Connect the Female fitting to the Male fitting as shown below in the drawing.
PROPERLY ATTACH EACH REGULATOR HOSE TO THE COMPRESSOR UNIT USING THE QUICK DISCONNECT COUPLING(S) THAT ARE ON EACH HOSE.
Assure no dirt or dust is in the Quick Disconnect coupling before attaching by following the steps above.
Place the hose underneath your weight belt as shown in the below photo.
Once the unit power is established, simply turn the Compressor switch to AUTO. The compressor will start, you will see the pressure increase immediately by observing the pressure gauge – once the pressure reaches 100 PSI the unit will automatically shut off. The unit will restart automatically when the pressure drops to a preset set point (approximately 74 PSI). The Dive Unit is now ready for use.
Place the regulator in your mouth. Breathe freely through the regulator as normally as possible. The SCUBA Breather regulator will function exactly as a conventional SCUBA unit regulator. On your inhalations you will experience breathing clean, dry, tasteless air. However, with a brand new dive unit, you may taste or smell the off-gassing of some of the materials used in construction of the unit - these will soon dissipate. Suggestion: To rid the Dive Unit of these gasses, start up the unit and let it free flow through the manifold port(s) for 15 minutes before the very first dive.
There is no time limit while underwater with the SCUBA breather; you could literally breathe underwater all day. The unit will continue to supply breathing quality air continuously.
As in any diving, you should have the following equipment:
Face mask -
A face mask will seal over your eyes and nose. Diving without a face mask is unpractical and very irritating to your eyes if diving in saltwater, dirty water, or water that has been treated with chlorine. Swimmers goggles are not recommended because they do not cover your nose; this will only make your dive more difficult.
Clearing the face mask – moisture will condense on the inside of the face mask glass and fog it up. The fog can easily be removed underwater by slightly breaking the seal of the face mask using your thumb and index finger and introducing just a tablespoon or two of water into the mask. Tilt your head down and swish the water around on the glass – this will immediately remove the fog.
Weight Belt -
Without a weight belt, a diver will float awkwardly at the surface and not be able to stay at depth without the sensation of “over buoyancy”. Purchase a weigh belt and adjust the weight accordingly as needed to achieve the proper buoyancy. Many divers like to be over weighted to the point where they can firmly stay at the bottom, but it's totally a matter of preference. You may very well find that the amount of weight needed to keep one particular diver at the bottom, will not be enough weight to keep another diver at the bottom – everyone’s buoyancy is a little different. Your physical make-up will determine the amount of weight you need. Generally speaking, thin people need less weight than heavy people. With a wet suit, you will need even more weight.
Do NOT overweight yourself on your first dive if diving in the ocean or any water that is over your head.
A swimming pool is the perfect place to get use to your dive system. Master the technique before moving on to deeper and rougher waters.
Wearing fins is part of any SCUBA divers equipment, it will allow you to swim freely like a fish – you should have a nice fitting pair.
Equalizing pressure in your ears -
Knowing how to "equalize" - When the diver leaves the surface and starts to submerge, the middle ear contains air at atmospheric pressure. As the diver descends deeper (about 7 feet), the external pressure on the eardrum will deflect inward; this inward pressure on the eardrum will definitely be noticeable to the diver. At this point the diver must "equalize" the pressure between the inside and outside of the eardrum. There are several acceptable ways to equalize that work for different divers. Most divers find that swallowing is all that is needed to equalize the pressure. Other divers pull downward on their ear lobe and rotate their jaw, or hold your nose closed with your finger and thumb and blow gently. As pressure equalizes, the diver will feel this and the inward pressure on the eardrum will diminish or more probably go away completely - you're on the right track. Continue to slowly descend repeating this procedure as many times as is necessary to balance out the pressure your ear. If you find that you get to a certain depth and you're having difficulty equalizing, re-ascend a short distance and try it again. With practice you'll get real good at it.
NEVER HOLD YOUR BREATH WHEN ASCENDING BACK TO THE SURFACE.
BREATH NORMALLY AS YOU ASCEND.
THIS IS REAL UNDERWATER DIVING!
