OVERVIEW OF FEATURES

The Sea Quest family of regulators consists of different models whichsatisfy a wide range of diving interests; from entry level sport diving, toadvanced diving in more demanding and extreme conditions. By now,your Authorized Sea Quest Dealer has already explained to you thespecific features that your particular model offers, and you have madeyour purchase after comparing the benefits of these features to yourindividual diving needs and interests. Be sure to review this section tolearn more about your model’s features and how to obtain the maximumbenefit from using them.

External Second Stage Adjustments (XR2 second stage only)

External adjustment features offer you the advantage of being able toadjust your second stage regulator’s sensitivity to suit your preference asyour diving conditions change. The XR2 second stage is equipped withtwo different adjustments, including an Inhalation Control Knob and aVenturi Assist Switch (see Fig. 1).

Venturi Assist Switch (Fig. 2)

The venturi assist switch is located onthe top of the XR2 second stage, in front ofthe mouthpiece, and helps to maintain ahigh flow of air once you have started totake a breath.

When the switch is set to the “MAX” position, the regulator will providemaximum venturi assistance. This makes it easier to breathe at deeperdepths and increased work loads.

For normal sport diving conditions, the regulator will perform suitably ifthe switch is left set to the “MIN” position. This setting will also help toprevent the second stage from freeflowing during entry or while swimmingon the surface.

Inhalation Control Knob (Fig. 3)

The inhalation control knob,located opposite of the hoseconnection on the XR2 second stage,adjusts the effort required to start theair flow at the beginning of theinhalation cycle. As it is turned “in”(clockwise), the opening effort willincrease. This will make the second stage less sensitive to suddenchanges in ambient pressure. Turning the knob “out” (counter-clockwise)will decrease the opening effort to make breathing easier.

This adjustment is particularly useful at deeper depths, or in variableconditions that affect the opening effort of the second stage, such asstrong currents or while using a diver propulsion vehicle (DPV). You canuse the inhalation control knob to tune your regulator to maintain its peakperformance throughout the course of your dive, or you can leave it set inits mid-range position and dive with it as you would any non-adjustablesecond stage.

For more information on using the XR2 second stage adjustmentsunderwater, refer to the section titled, Diving With the XR2.

First Stage Environmental Protection

For diving in cold water conditions or heavily silted water, Sea Questoffers three optional environmental protection kits for the Infinity, Mirage,and Spectrum first stages, which must be installed by your AuthorizedSea Quest Dealer. Each of these kits is designed to seal the first stagefrom the environment, thereby preventing the entrance of any silt or coldwater. It is important to remember, however, that this environmentalprotection will only prevent ice from forming in the first stage ambientchamber, and will not prevent the second stage from icing or freezing.

The kits for the Infinity andMirage, which are both pistondesign first stages, contain sili-cone gel that fills the ambientchamber to completely surroundthe piston and valve spring. Aprotective cap or sleeve is theninstalled over the ports of theambient chamber to retain thistransfer medium (see Fig. 3).

The Spectrum first stage, which features abalanced diaphragm design, uses a special"DRY" environmental protection kit. The DRY kitalso seals off the ambient chamber with anexternal diaphragm, but incorporates a speciallydesigned piston to transfer the surrounding waterpressure to the internal diaphragm, instead of asilicone medium.

"Cryo" Cold Water Second Stage

The XR2 regulator is also available in a cold water version; the XR2Cryo, which includes the Spectrum DRY first stage. This model features apatented heat exchange system that effectively reduces the possibility ofsecond stage freezeup by drawing inthe surrounding water temperature towarm the valve mechanism (see Fig.5). Standard XR2 regulators can beupgraded to the Cryo version by yourAuthorized Sea Quest Dealer.

For important information aboutdiving in cold water, refer to the sec-tion titled, Cold Water Diving.

Optional DIN Adapter (Spectrum & Mirage Only)

Your Sea Quest regulator is sold with a standard U.S. yoke connec-tion, which is approved for use with cylinder pressures up to 3,000 psi. Ifyou intend to use your regulator with ahigh pressure cylinder equipped with aDIN valve, a DIN adapter is availableseparately for the Spectrum or Mirage firststage which can be purchased from andinstalled by your Authorized Sea QuestDealer (see Fig. 6).

Installation of a first stage DIN adapter must only be performed byan Authorized Sea Quest Dealer, and must not be attempted byunauthorized individuals. Failure to obtain this service through anAuthorized Sea Quest Dealer may result in faulty installation, andcould lead to severe injury or death.

PREPARATION AND SETUP

Sea Quest recommends that you bring your regulator to your Autho-rized Sea Quest Dealer for the installation of any accessory items,including instrumentation, LP quick disconnect hoses, and alternate airsource second stages. Your dealer can also answer any questions youmay have pertaining to the information in this manual.

1. (XR2 second stage only) Check the venturi assist switch on the top ofthe second stage to ensure that it is set to the “MIN” position prior toconnecting your regulator to the tank.

2. (XR2 second stage only) If the inhalation control knob has beenturned “out” (counter-clockwise), gently turn it “in” (clockwise), onlyuntil it stops. Do not apply excessive pressure.

3. If you are using a standard cylinder with a yoke connector valve,inspect the cylinder valve O-ring for any wear or damage. If you areusing a high pressure cylinder with a DIN valve, remove the protectorcap from the first stage to inspect the sealing O-ring of the DINconnector. If the sealing O-ring is damaged or worn, replace it beforemounting the regulator on the cylinder valve.

Mounting the First Stage Onto the Cylinder Valve (Yoke Connector)

1. Partially unscrew the yoke screw of the first stage regulator so thatthe dust cap can be removed from the filter and air inlet.

2. With the cylinder valve facing away from you, release a small amountof air from the cylinder by turning the handwheel counter-clockwise toopen the valve only slightly. When air is heard exiting, immediatelyclose the valve. This will clear any moisture or debris that may beinside the cylinder valve outlet opening.

3. Place the first stage regulator over the cylinder valve so that the inletfitting aligns with the O-ring of the cylinder valve, and the LP hose ofthe primary second stage will be routed over the right shoulder. Whileholding the first stage in place, turn the yoke screw clockwise.Ensure that the yoke screw mates into the small dimple on thebackside of the cylinder valve, and tighten finger-tight only.

4. If a submersible pressure gauge is attached to the first stage, ensurethat the gauge is facing away from you. Pressurize the regulator byslowly turning the cylinder valve handwheel counter-clockwise. Con-tinue to turn the valve handwheel counter-clockwise until it is fullyopen, and then turn it back clockwise 4-2 turn.

5. Listen near the first stage to check for any leakage. If leakage isdetected, immerse the first stage and cylinder valve while pressurizedto determine the source.

6. If leakage has been detected, follow the procedure for removing theregulator from the cylinder valve on page 13. If air was leakingbetween the first stage and cylinder valve, replace or re-seat thecylinder valve O-ring as needed and repeat the above procedure. Ifleakage persists, return the cylinder and regulator to an AuthorizedSea Quest Dealer.

Mounting the First Stage Onto the Cylinder Valve (DIN Connector)

1. Remove the protector cap from the cylinder valve. With the cylindervalve facing away from you, release a small amount of air from thecylinder by turning the handwheel counter-clockwise to open thevalve slightly. When air is heard exiting, immediately close the valve.This will clear any moisture or debris that may be inside the threadedcylinder valve opening.

2. Position the first stage near the cylinder valve so that the LP hose ofthe primary second stage will be routed over the right shoulder.Thread the first stage DIN connector into the cylinder valve and turnthe handwheel clockwise by hand until it is lightly snug. DO NOT usetools to tighten.

3. If a submersible pressure gauge is attached to the first stage, ensurethat the gauge is facing away from you. Pressurize the regulator byslowly turning the cylinder valve handwheel counter-clockwise. Con-tinue to turn the cylinder valve handwheel counter-clockwise until fullyopen, and then back clockwise 4-2 turn.

4. Listen near the first stage to check for any leakage. If leakage isdetected, immerse the first stage while pressurized to determine thesource.

5. If leakage has been detected, follow the procedure for removing theregulator from the cylinder valve on page 13.

PRE-DIVE INSPECTION

Before each use, the regulator must be given a thorough visualinspection and functional test. NEVER dive with a regulator that showssigns of damage or unsatisfactory performance until it has receivedcomplete inspection and service from an Authorized Sea Quest Dealer.

Inspection Checklist:

1. Carefully inspect all hoses at their fittings to ensure they are securelyconnected into their respective ports on the first stage. Inspect thelength of each hose to ensure that the hoses are not blistered, cut, orotherwise damaged. If hose protectors are present, slide theprotectors back to expose the hose fittings, and inspect the hoses asdescribed above.

2. Visually inspect both the first and second stage regulators for anysigns of external damage.

3. Remove the dust cap and closely inspect the condition of the firststage filter. It should appear clean and free of any corrosion ordiscoloration. If a green residue is visible on the surface of the filter,moisture has entered the first stage and may have caused corrosionto begin forming inside which can seriously impair the regulator’sperformance. Other colored residue may indicate that the regulatorhas been used with an internally corroded aluminum (white/ graypowder) or steel (rust) cylinder. In this event, the regulator and thecylinder in question should be returned to the dive store for internalvisual inspection.

If discoloration or contaminant residue is found to be present onthe surface of the filter, it is strongly recommended that you DONOT attempt to dive with the regulator until it has received factoryprescribed service from an Authorized Sea Quest Dealer.

4. (Environmentally sealed first stages only) Closely inspect the exter-nal sealing diaphragm or protective cap for any signs of damage ordeterioration that may cause leakage. For the Spectrum "DRY," theretainer that holds the external diaphragm in place must be tightlysecured.

PRE-DIVEINSPECTION

12

If the environmental kit shows any signs of damage or neglect,DO NOT attempt to dive with the regulator until it has receivedfactory prescribed service from an Authorized Sea Quest Dealer.Under this condition, the regulator may seem to function normallyat the surface, but may not provide adequate airflow at depth.The environmental protection may also be compromised, andcould result in first stage freeze-up in cold water conditions.

5. Connect the first stage regulator to a fully charged SCUBA cylinder.For mounting instructions, read the Setup section on page 7.

6. SLOWLY open the cylinder valve to pressurize the regulator. De-press the purge button momentarily to blow out any dust or debriswhich may have entered the second stage.

7. Release the purge button and listen to ensure that the second stagedoes not continue to flow any air after the purge button is released.

8. (XR2 second stage only) Turn the inhalation control knob “out”(counter-clockwise) until a slight leak is heard, and then back "in"(clockwise) until the regulator provides maximum ease of breathingwith no leakage present. Do not apply excessive pressure.

9. Inhale slowly and deeply from the regulator several times. Theregulator must deliver enough air for you to breathe easily withoutnoticeable resistance.

10. Check to ensure that the submersible pressure gauge is displaying anaccurate measurement of the air pressure inside the cylinder.

11. Close the cylinder valve and bleed the air from the regulator bypressing the purge button. Look at the submersible pressure gauge,or your dive computer if it is air integrated. The air pressure readingmust fall to zero. If you are not certain the gauge or computer isreading correctly, do not dive with the system until it has receivedinspection and service from an Authorized Sea Quest Dealer.

12. (XR2 second stage only) Check to ensure that the venturi assistswitch is set to “MIN” and gently turn the inhalation control knob back“in” (clockwise), only until it stops. Do not apply excessive pressure.These settings will help to minimize any loss of your air supply duringentry or while making a long surface swim.

13. Before entering the water, turn the cylinder valve completely open andthen back 4-2 turn to ensure that the regulator is pressurized.

DIVING IN COLD WATER

Before attempting an unsupervised dive in cold water conditions, it isimportant for you and your buddy to obtain certified training in cold waterdiving techniques, and to ensure that your breathing systems are properlyequipped for this diving specialty. If these precautions are not taken,freeze-up can occur, especially in fresh water lakes where thermoclinesmay be encountered.

After receiving training, you should bring your regulator to an Autho-rized Sea Quest Dealer for inspection and any service that may beneeded. Your regulator may require the installation of additional parts thatwill render it more suitable for cold water use, or you may be advised topurchase a different model that is better designed for this purpose.

It is possible for icing or freeze-up to occur, even with a regulator thathas been specially designed and/or prepared for cold water use. For thisreason, it is imperative that you must practice the correct cold water divingprocedures, and take special precautions to prevent second stage icing.This training must include procedures for dealing with regulator freeze-up,unexpected freeflow, and emergency out-of-air situations. These proce-dures are taught in cold water training programs provided by mostrecognized certification agencies.

Whenever your air cylinder is filled, request verification that the watervapor content of the supplied air is less than -65°F dewpoint. (Most divestores and air stations obtain regular testing and certification to provideevidence of compliance with pure air standards.) Excess water vapor inthe air can cause moving parts inside your regulator to ice-up and freeze.

SCUBA regulators and other equipment have operational limitswhen used in water colder than 45°F (7°C). If you attempt to divein cold water without first obtaining the necessary training andpreparation of your equipment, you risk serious injury and death.

COLD WATER

14

DIVING WITH THE XR2 ADJUSTABLE SECOND STAGE

When you are ready to submerge, turn the inhalation control knob onthe left side of the XR2 second stage all the way “out” (counter-clockwise). Then, turn the knob back “in” (clockwise) until the regulatorbreathes comfortably without leaking or being undesirably sensitive.

For XR2 regulators sold in the United States, it is normal for thesecond stage to continuously leak air when the inhalation controlknob is turned all the way “out” (counter-clockwise), in order toprovide the maximum range of adjustment.

As you descend, you may want to turn the regulator knob further out tomake breathing easier. This will be particularly true on deep dives wherethe air becomes denser. Remember, however, that the regulator maycontinuously leak air if the inhalation control knob is turned completely“out,” and that this will cause the air supply to be depleted more rapidly.

Adjusting your regulator to increase breathing resistance will notconserve air. Instead, excessive breathing resistance will actu-ally increase air consumption, and may elevate the CO

2 in your

bloodstream to a dangerous level which could lead to seriousinjury or death due to drowning if you lose consciousness.

If you swim underwater in an upside down or sideways position, orfacing a strong current, you can turn the inhalation control knob back “in”(clockwise), to desensitize the opening effort to prevent any freeflow.

If you turned the venturi assist switch to the “MAX” position at any timeduring your dive, be sure to return it to the “MIN” position when youascend to the surface, and also turn the inhalation control knob “in.”

Deep diving requires special training and equipment, and greatlyincreases your risk of decompression sickness and other seriousdiving injuries. If you attempt to dive beyond prescribed no-decompression limits without first obtaining sanctioned technicaldive training, you risk serious injury and death.

AFTER THE DIVE

If fresh water is available, rinse your regulator completely beforedepressurizing it, and thoroughly dry the first stage and cylindervalve with a soft cloth. This will help to prevent any contaminantsfrom entering the regulator when it is removed from the cylinder.

Removal of the Regulator from the Cylinder Valve (Yoke Connector)

1. Shut off the cylinder air supply by turning the cylinder valvehandwheel clockwise until it stops.

2. While observing the submersible pressure gauge, depress the purgebutton of the second stage. When the gauge reads zero and airflowcannot be heard from the second stage, release the purge button.

3. Turn the yoke screw counter-clockwise to loosen and remove the firststage from the cylinder valve.

4. Dry the dust cap with a clean towel, or with low pressure air. Becareful to avoid blowing out the dust cap O-ring and losing it.

5. Place the dust cap over the first stage inlet fitting and seal it securelyin place by tightening down the yoke screw.

Removal of the Regulator from the Cylinder Valve (DIN Connector)

1. Turn off the cylinder air supply by turning the cylinder valvehandwheel clockwise until it stops.

2. While observing the submersible pressure gauge, depress the purgebutton of the second stage. When the gauge reads zero and airflowcannot be heard from the second stage, release the purge button.

3. Turn the first stage handwheel counter-clockwise to loosen andremove the first stage from the cylinder valve.

4. Blow out any water inside the protector cap or wipe it out with a softcloth, and wipe the threads of the first stage connector clean and dry.Install the cap over the threads of the first stage connector.

Be careful when removing the first stage from the cylinder valve toensure that moisture does not enter either the inlet opening of thefirst stage or the opening of the DIN valve.

CARE &MAINTENANCE

16

5. With the cylinder valve facing away from you, open the valve slightlyto release a short burst of air, and then immediately close the valve.This will clear any moisture that may have entered the valve opening.Immediately seal the protector cap securely in place over the openingof the DIN valve to prevent the entrance of moisture or debris.

USER CARE & MAINTENANCE

It is important to provide the proper preventative maintenance in orderto ensure the best possible performance and maximum life of your SeaQuest Regulator. The following maintenance procedures should beperformed routinely after each use to ensure that the regulator is cleaned,inspected, and prepared for the next use or for storage.

1. Whenever the regulator is removed from the cylinder valve, it isimportant to wipe or blow the dust cap completely dry, and then fastenit securely over the first stage inlet fitting. This is critical to prevent theentrance of moisture into the first stage. Check to ensure that the O-ring is seated securely inside the dust cap.

2. As soon as possible after diving, the regulator should be rinsedthoroughly with fresh water while it is attached to a cylinder andpressurized with air.

3. Rinsing alone, however, will not sufficiently clean the regulator. Toclean the regulator as thoroughly as possible, it is necessary to soak itin warm (not over 120°F) tap water for at least one hour.

a. The preferred method is to attach the regulator to a charged SCUBAcylinder, open the cylinder valve to pressurize the regulator, andthoroughly soak both the first and second stages. Pressurizing theregulator will effectively prevent the entrance of moisture and/orcontaminants into the regulator while it soaks.

b. If it is not feasible to soak the regulator while it is attached to acylinder, it may be soaked unpressurized – provided that the dust capis securely sealed over the inlet with its O-ring intact, and the secondstage purge buttons are not depressed while the regulator is sub-merged or wet.

When soaking or rinsing an adjustable model regulatorunpressurized, check to ensure that the second stage inhalationcontrol knob is turned completely “in” (clockwise) to preventmoisture from entering the valve and LP hose.

CARE &MAINTENANCE

Regulators

17

DO NOT loosen the first stage yoke screw, depress the secondstage purge button, or turn the inhalation control knob out (XR2model) if the regulator is submerged unpressurized. Doing so willallow the entrance of moisture, and will require that the regulatorbe returned to an Authorized Sea Quest Dealer for service.

4. (XR2 second stage only) While the regulator is soaking, move theventuri assist switch on the second stage (if present) back and forthseveral times from the “MIN” to the “MAX” settings. You may also turnthe inhalation control knob slightly back and forth—no more than 4turn. This action will help to loosen any salt or mineral deposits thatmay remain lodged in the second stage.

5. After the regulator has been properly soaked, it is important to rinse itvigorously by flushing the first stage ambient chamber (non-environ-mentally sealed models only), the second stage mouthpiece, and theopenings in the second stage front cover with a pressurized stream ofwater. This will remove any deposits of salt and minerals that wereloosened during soaking. If the regulator is not pressurized, do notpress the purge button underwater. Moisture may otherwise enter thevalves, which will require that the regulator be returned to anAuthorized Sea Quest Dealer for service.

6. Wipe the regulator as dry as possible and hang by the first stage toensure that all remaining moisture drains from the second stages.

7. XR2 second stages should be stored with the knob turned all the wayout (counter-clockwise), away from the regulator body. This will helpto extend the life of the low pressure seat.

8. When the regulator is completely dry, store it in a clean box or sealedinside a plastic bag. Do not store it where it may be exposed toextreme heat or an electric motor which produces ozone. Prolongedexposure to extreme heat, ozone, chlorine, and ultraviolet rays cancause premature degradation of rubber parts and components.

9. Never store the regulator while it is connected to the cylinder valve.

10. Do not use any type of solvent or petroleum based substances toclean or lubricate any part of the regulator. Do not expose any part ofthe regulator to aerosol spray, as some aerosol propellants attack ordegrade rubber and plastic materials.

DEALER SERVICE & REPAIR

1. It cannot be assumed that a regulator is in good working order on thebasis that it has received little use since it was last serviced.Remember that prolonged or improper storage can still result ininternal corrosion and/or deterioration of O-ring seals.

2. You must obtain factory prescribed service for your regulator at leastonce a year from an Authorized Sea Quest Dealer, regardless of theamount of use it has received. Your regulator may require this servicemore frequently, depending on the amount of use it receives and theenvironmental conditions in which it is used.

3. If the regulator is used for rental or training purposes, it will requirecomplete overhaul and factory prescribed service every three to sixmonths. Chlorinated swimming pool water is an especially damagingenvironment for SCUBA equipment, due to the high levels of chlorineand pH balancing chemicals which cause certain components torapidly deteriorate.

4. DO NOT attempt to perform any disassembly or service of yourregulator. Doing so may cause the regulator to malfunction, and willrender the Sea Quest warranty null and void. All service must beperformed by an Authorized Sea Quest Dealer.

OBTAIN SERVICE FOR YOUR REGULATOR AT LEAST ONCE AYEAR, FROM AN AUTHORIZED SEA QUEST DEALER. YOUR PER-
