Hookah Operating and Diving surface- supplied equipment (The Air Line Models AL-R260 and AL-C360)
Hookah Systems When diving a hookah system, people use standard scuba masks, fins, and weight belts – but do not wear tanks on their backs. Rather, a standard second stage demand regulator is coupled with a low pressure air hose fed from a compressor on the surface.
The Air Line Hookah System This Hookah rig consists primarily of a gasoline engine powered compressor, a float tube to support the compressor, and air lines with regulators for divers. The R260 model supports 3 divers, while the larger C360 model supports 4 divers.
Operating the R260 and C360 Both units are contained in a protective hard case. Unsnap the travel straps that go around the unit’s middle section, and the short strap on top of the case. Remove the cover.
Operating the R260 and C360 Remove the dust cap (slide 7) from the black intake socket located on top of the compressor (The R260 has one of these, the C360 has two). Place the clear PVC intake staff into the socket as far as it will go (slide 8). DO NOT START THE ENGINE WITH THE DUST CAP ON. The dust cap must ALWAYS BE IN PLACE WHEN THE STAFF IS REMOVED. This prevents water or dust from getting into the compressor head.

Operating the R260 and C360 Starting the unit (see slides for control locations) –Make sure the oil reservoir and gas tanks are full. –Put the fuel valve in the “ON” position. –Turn the ON/OFF switch to “ON”. –Move the throttle lever down slightly –Start the engine – pull the starter grip lightly until resistance is felt, then pull briskly. If it is cold, it might be necessary to choke it. Put the choke lever in the closed position As it warms, return the choke to the open position. –Put the throttle speed on “Fast”.
Oil filler cap/dipstick. Check oil level here, before starting motor. To do so, insure that unit is on a level surface, remove the cap and wipe it clean, insert the cap back into the unit (but do not screw it in), then remove it to check the oil level. If oil appears on the dipstick, then there is enough oil to operate the unit.

Operating the R260 and C360 –Note: The black heat transfer hose (or compressor hose) (slide 15) needs to be in the water for cooling hot compressor air. It is perfectly alright to have it out of the water for start up, filling the tube, or washing down if the yellow air hoses are not attached, but prolonged running out of the water with the yellow hoses attached will cause the more delicate yellow hose to soften and burst or possibly slip off the fitting creating a potentially dangerous situation.
Compressor/ Heat transfer hose
Operating the R260 and C360 Fill float tube with air using compressor –Pull back on the sleeve of the inflator fitting, push fitting onto the float tube valve as far as it will go and release sleeve. –Fill to where the cover is just full, but with a slight amount of room to allow for expansion when the sun is heating it. Do not try to get all of the wrinkles out of the tube cover, this would be too full. You are ready to place the compressor pan in the tube. The compressor pan should nest snugly in the center of the tube with just a little pressure on it. If it does not, remove a slight bit of air.
Operating the R260 and C360 To nest the pan in the tube: –Coil the long black strap into the pan –Work the black compressor hose into the hole directly in the front of the pan –Dangle the 2 short black straps and compressor hose into the center of the inflated tube –Place the pan into the tube –Bind the compressor pan to the tube with the short black straps. –Bring the long strap all the way under and around the whole tube, connect it and snug it up.
Note black straps connecting compressor pan to tube.
Operating the R260 and C360 Attaching hoses to the compressor hose. –Hoses may be attached only one way, i.e. male garden hose to female garden hose. Hose handling –To keep kinks out of the hose, always unreel rather than uncoil hoses. Hold the reel perpendicular to your chest as though you were holding a bass drum and play out the hose with a reeling motion. By doing so, the hoses will be straight when you have launched the float and it travels down wind. Retrieve hoses the same way.

Operating the R260 and C360 Boat Launching –Position 2 people on either side of the unit, being careful not to touch the hot exhaust cage. Gently lower the unit into the water with as little angle as possible, or at least with the gas cap at the highest point. Push the unit away from the boat, playing out the hoses as it goes. –The unit should never be towed behind a boat. It will sink.
Operating the R260 and C360 Stopping the unit –Stop the engine with the On/Off switch, and let the unit float away. –Purge the regulators to eliminate pressure. –Retrieve hoses starting with the regulators by coiling them in. –Carefully lift the unit onto the boat.
Manufacturer depth ratings for C360 and R260. Maximum depths at which a particular system can be used are dependent upon how many divers are using the system, as well as the breathing demands placed on the system by the divers. Diving the R260 and C360 - Depths
Diving the R260 and C360 – Run Times Both units will run approximately 2 hours before refueling becomes necessary. Long hookah run times require that EXTRA ATTENTION BE PAID TO DEPTHS AND DOWN TIMES. Divers are cautioned to never dive past a no-decompression limit on any surface supplied air system. Should the engine run out of gas or be accidentally turned off, the consequences would be very serious.
Diving the R260 and C360 The regulator hose is clipped to a belt worn by the diver. The regulator is then routed over the back and right shoulder of the diver. The belt also holds a Spare Air bottle for emergency bail-out. (Note: weight belts must be positioned so that they will not get hung up on the Spare Air belt when released in an emergency situation.) Divers wear BC’s – However, there is no automatic inflation for BC’s with the basic system, so BC inflation must be done orally, or a separate pony bottle may be incorporated into the system.

Emergency Procedures Signals of Stopped Motor –Should you feel that your last breath was slightly more difficult than the one previous, it is probably an indication that the motor has stopped. Note too, that motor vibrations can usually be felt through the regulator hose – in the event the motor ceases to run, these vibrations will stop.
Emergency Procedures If you sense the motor has stopped, you have two choices: –Rather than continuing to breathe the last of the air remaining in the hose, start an immediate ascent while exhaling slowly. As you ascend, air in the hose will expand. As you feel the need, breathe in from the hose. –Switch to your Spare Air and make a proper ascent to the surface.
Spare Air – Model #300 Contains 3 cubic feet of air at 3000 psi White pin in center of aluminum piece opposite mouthpiece indicates the level of air in the unit. When full, the pin is flush with the outer edge of groove (slides 30-32) The purge button is located at the top of the Spare Air (slide 30).

Post Dive Maintenance After the engine is cooled (putting water on a hot motor can damage it), with the air intake assembly in place and the yellow hoses unscrewed, start up the engine and immediately start thoroughly spraying down the entire unit with fresh water with the engine running at idle to half speed. Do not force water into the compressor air intake or into the engine air filter (slide 34).

Post Dive Maintenance The dust cap on the compressor intake socket has a smaller red cap inside it (Slide 36). Pull out the air intake staff and pour one red capful of water into each compressor head through the compressor air intake. Let the engine run 10 seconds and pour in another capful. Repeat this several times, replace the staff, and let the engine run at least 4-5 more minutes to ensure that the compressor has dried internally.

Post Dive Maintenance While the motor is still running, spray Corrosion X lubricant into the engine pull cord housing (slide 38), and lightly coat all linkage parts and hardware of the motor. If you are not going to use the unit for the rest of the day, turn off the fuel valve switch at the end of the wash down and allow the carburetor to run dry. The motor will rev up and down as it begins to run out of fuel – do not be alarmed.
