Unless otherwise specied TUSA regulators should be used only with open circuit compressed air breathing equipment. Its use with oxygen-enriched air is not autho- rized and is dangerous. The compressed air must be in compliance with the stan- dard EN 12021. Before any attempt is made to use this regulator underwater, you MUST have re- ceived training and CERTIFICATION in the technique of sport diving from a recog- nized certication agency. Use of this equipment by a person who is not certied by a recognized agency shall render all warranties, express or implied, null and void. Use of regulators by uncertied or untrained persons is dangerous and can result in severe injury or death. This regulator is not intended for commercial use with surface supplied air. Before each use, the regulator must be given a thorough visual inspection and func- tional test. NEVER dive with a regulator which shows signs of damage or provides substandard performance. Always use regulator as designated combination of rst stage and second stage. As inappropriate combination of rst and second stages may result deterioration of per- formance, do not connect other second stage to these (R-300, 500, 600) rst stages or vice versa. Repair, servicing, or addition of accessories (e.g. pressure gauge) to this regulator is to be performed ONLY by a qualied TUSA Service Facility. The HP and LP outlets of the rst stage have intentionally been tted with different threads to prevent the possibility of incorrect tting of accessories. Always apply pressure to the regulator gradually by opening the cylinder valve SLOWLY, NEVER lubricate any part of the regulator (especially the rubber O-ring seal between the cylinder valve and regulator) with a hydrocarbon-based lubricant.

TUSA Regulators are BALANCED PISTON and BALANCED DIAPHRAGM type SIN- GLE HOSE REGULATORS. The regulator reduces high pressure air from the scuba cylinder to ambient pressure suitable for breathing, through the operation of rst and second stage regulators. The rst stage regulator reduces incoming high pressure air, to an intermediate pressure of approximately 135PSI ( 9.5bar). The second stage regulator, using a diaphragm operated demand valve, further reduces air from intermediate pressure to ambient pressure permitting normal breathing. The rst and second stages of the regulator are connected by a low pressure hose. A swivel yoke (TYPE INT) on the rst stage body secures the regulator to the cylinder valve, while an O-ring surrounding the outlet orice on the cylinder valve ensures an airtight con- nection to the rst stage.

R-300 rst stage In order to achieve natural breathing, a dynamic ow hose with a large inner diam- eter increases the airow. The R-300 always supplies the diver with stable air at any tank pressure or depth, delivering maximum breathing ease and comfort for them. R-400 rst Stage The TUSA R-400 offers a first stage with the balanced diapraghm method. This method features minimum variation in intermediate pressure in response to changes in residual cylinder pressure and depth. The R-400 is engineerd for cold water diving (EN-250-2000). It also offfers two high high ow LP ports (HFP) that are close to the diapraghm to increas the airow by aproximately 15%. R-500 rst stage The very popular balanced piston type rst stage offers superior reliability for stable air supply regardless of depth or residual pressure. R-600 and R-600 DRY rst stage With the R-600, offers a compact design weight of just 630g during actual use. This allows the R-670 to only be a total weight of just 1050g for the rst and sec-- 22 - Regulators

ond stages.The balanced diaphragm method rst stage features minimum variation in intermediate pressure in response to changes in residual cylinder pressure and depth. The ports are in left-right symmetry (H.P. × 2, L.P. × 4) for easier attachment to tanks, even for beginners. R-700 rst Stage The R-700 is a balanced diaphragm first stage with key design and performance characteristics:

1) Four intermediate pressure ports and two high pressure ports, 2) Balanced rst

stage, with a built-in antifreeze system, 3) Replaceable HP seat and HP poppet for durability and servicing, 4) Two special high ow LP ports (HFP) close to the dia- phragm offer approximately 15% greater air ow, 5) Dry balance chamber prevents water contact with the diaphragm and the spring for superior cold water perfor- mance. The R-700 meets the European Standards EN250:2000 requirements for cold water conditions. R-800 rst Stage The R-800 is a balanced piston type rst stage offering superior reliability for stable air supply regardless of depth or residual pressure. It is equipped with four interme- diate low pressure ports and two high pressure ports.

New mouthpiece The new mouthpiece, developed on the basis of ergonomic engineering, further enhances the comfort of bite, t, and stability. Even with a light bite, a high level of stability is achieved, so there is no fatigue from long periods of usage. Venturi Adjustment Lever (RS-460, 680, 790, 811, 812, SS-60, 80) The addition of a venturi adjustment lever allows the regulator to power assist the diver when underwater utilizing the natural venture effect. The diver can also adjust the lever to prevent free ow such as on a surface swim. Swivel joint (RS-340, 350, 670, 680) For optimum performance and comfort, a swivel joint is tted between the second stage and the joint section of the low pressure hose. The swivel joint allows exibility of the hose for eliminate hose tension at the mouthpiece for a more natural and com- fortable bite. “Air Refresher” lter (RS-350) There are two types of high tech lter built into the second stage. An active carbon lter cleans the air and absorbs smells, while a metal ber ler eliminates particles as small as 100 microns.This makes sure that the cleanest and safest air is supplied to the diver.

SECTION III PRE-DIVE PROCEDURES WARNING Do not attempt to connect low pressure hoses to the high pressure ports with the use of an adapter. Improper connection will cause damage to the equipment and could result in serious personal injury. Low pressure components are not intended to withstand pressures greater than 28Bar

(400 PSI). When installing your accessory hoses, avoid damaging the O-ring. Tighten gently, but firmly into the first stage housing. SCUBA complying with EN 250 are not intended for more than one user to breathe from at the same time. If SCUBA are configured and used by more than one diver at the same time, then the cold water and breathing performances may not fulfil the requirements of EN 250. RS-350, 340 Always connect the Octopus Regulator to the portmarked with SS. Connecting to any other port is strictly prohibited.

PRE-DIVE OPERATING INSTRUCTIONS

1. Position the tank valve so the outlet points toward the diver.

2. Remove the dust cap from the first stage inlet and place the yoke (or DIN adaptor)

in the center of the cylinder valve connection.

3. Position the first stage body so that the second stage hose goes over the right

shoulder of the diver.

4. Hand-tighten the yoke screw or DIN adoptorscrew.

5. Check all the hose connections to the first and second stages. If they can be

loosened by hand, they should be tightened with a wrench before pressurizing.

6. Check the submersible pressure gauge to make sure it indicates zero pressure.

7. Open the tank valve slowly to gradually allow air into the regulator.

NOTE: During this operation, depress the second stage purge button to reduce shock to the valve mechanism. Do not perform this operation in a cold environment below 10°C (50°F). Performing this in a cold environment may cause “freeze-up” of the regulator which can render it inoperable. If this occurs, you should contact a TUSA authorized service center.

8. Check the submersible pressure gauge to ensure that it indicates the proper tank

pressure.- 25 - Regulators

9. Check the tank/regulator connection for leakage. If leakage exists, it may be cause

by incorrect mounting of the regulator on the tank valve, or by a damaged O-ring i

10. To confirm that the regulator delivers air properly, first exhale through th

mouthpiece to blow any foreign matter out of the second stage, then inhale. A fe

of these breathing cycles should immediately indicate proper function.

11. If you are using the second stage as an Octopus regulator, it is strongly recom

mended to utilize an Octopus plug to prevent any foreign matter from entering th

second stage through the mouthpiece.

12. When the second stage is not in your mouth, uncontrolled air delivery can tak

place. This can be stopped by turning the second stage upside down and allowin

it to fill with water. Should the air delivery continue, abort the dive and have th

regulator inspected by a TUSA Authori zed Service Center. SECTION IV

AFTER DIVE PROCEDURES

Providing the best possible preventative and routine maintenance before, after, an

between dives will help to ensure the maximum life of your TUSA Regulator. To achiev

this goal, there are a number of simple, yet important, routine maintenance procedure

that should be followed by the diver after each use of the equipment. The follo wing procedures should be diligently followed in order to obtain the maximum life and serviceability from your regulator.

1. After each day of diving, the regulator must be cleaned, inspected, and prepared f

the next use, or for storage. As soon as the regulator is removed from the ai

cylinder, reinstall the dust cap over the regulator inlet port. This cap is normall

attached to the First Stage and therefore has been under water. Be sure to dry all the water out of this cap before securing it over the inlet port. Ensure that the O-r ing, if fitted, is in place inside the dust cap.

2. As soon as possible after diving, the regulator should be soaked in warm, not ove

50°C (122°F) water to remove salt and mineral deposits.The preferred method is t

attach the regulator to a charged air cylinder, open the cylinder valve, an

thoroughly soak both the first and second stage regulators . Pay particular attentio

to directing water into the mainspring cavity of the first stage regulator, the secon

stage mouthpiece, and the holes in the second stage cover. Depress the purg

button several times while the regulator is submerged in water. Dry the regulator b

pressing on the purge button with the mouthpiece pointing down. Place the dust ca

in position in the yoke, or over the DIN screw. Regulators

CONTAMINATED WATER DIVING

Sophisticated diving gear designed for use in contaminated water provides constant positive pressure inside the regulator case and utilizes redundant exhaust valve passages. TUSA regulators are not designed to provide this requirement and therefore are not recommended for use in contaminated water diving. SECTION VI

This is important information. Be sure to read it.

RS-350/340/680/790DRY regulators for the European market have passed the cold water performance test (water temperature: 4°C) specified by EN250. Soaking regulator parts in warm water will remove more salt and mineral deposits than will conventional rinsing. It will loosen deposits on interior components that rinsing will not (If no charged air cylinder is available, follow the above procedure but be very careful NOT to depress the purge button, or leave dust cap off, when the regulator is submerged in water. Failure to do this will allow water to enter both regulator stages and may result in internal corrosion). Simply soak the entire exterior of the first stage thoroughly, and proceed as above when cleaning the second stage.

3. Store in a clean equipment box, or as an alternative, seal inside a plastic bag. Store

in a clean dry place.

4. Lightly lubricate the yoke screw with silicone grease.

5. Never store the regulator while it is still connected to the diving cylinder.

6. Do not use any type of solvent to clean any part of the regulator. Do not expose any

part of the regulator to silicone spray, as some aerosol propellants attack or degrade rubber and plastic material.

7. Do not carry the diving cylinder by the regulator as such abuse will eventually

damage the regulator or the cylinder valve. Do not expose the regulator to unnecessary shocks or impact.- 26 - Regulators

1. Do not assume that a regulator is in good working order because of storage or

infrequent use. Remember that either prolonged or improper storage can still result in internal corrosion and/or deterioration of O-ring seals.

2. Have your regulator cleaned and adjusted frequently. The frequency will depend

upon the amount of use given the regulator and the conditions of use. However, TUSA strongly recommends inspection, overhaul and scheduled parts replacement at least once a year in order to ensure the optimum functioning of the regulator. Certain parts require replacement at specific intervals. This work must be carried out by a competent service facility. Use as rental equipment and/or in salt, chlorinated (swimming pool), or polluted fresh water might require cleaning and overhaul of the regulator every three to six months. Remember that chlorinated

Regulators When using these regulators in cold water at temperatures of 10°C or below, be sure to observe the following notices. General Caution Items

• Before you use the regulator, be sure to receive specialized instruction on cold water diving from a diving instruction authority so that you learn the necessary skills and knowledge.

• Be sure to receive orientation for the diving environment.

• Be sure to obey the instructions of your instructors and guides. Equipment Handling Caution Items The conditions for freezing up of the regulator change in accordance with the breathing conditions of its user (breathing volume, breathing speed, number of breaths) and the environment conditions before and during use.

• Do not take shallow, fast breaths. It makes freezing occur more easily.

• To avoid free flow condition due to freezing NEVER push the purge button while the regulator is outside of the water.

• Store the regulator at room temperature. When diving, store your regulator in its bag to keep it warm until just before use.

• When waiting between dives, always keep your regulator warm. Do not leave it out in a cold environment.

• Your regulator may freeze depending on the conditions. If your regulator freezes, it may free flow. If it does, use breathing technique for free flow conditions.

• When diving in water temperatures of 10°C or below, always swim at a safe depth from which you can perform an emergency swimming ascent. SECTION VIII

“AIR REFRESHER” FILTER REPLACEMENT

1. The timing for replacing the filter is the same as for the equipment overhaul. TUSA

strongly recommends that you have your filter replaced every 100 dives, or a year after purchase or the last overhaul (or filter replacement) regardless of the condi- tions of use.The TUSA repair facility will replace the filter during the overhaul, so be sure to have your equipment overhauled at the specified interval. If you have already had your equipment overhauled and only wish to replace the filter, you must also have this work carried out at a specialist outlet or TUSA facility.

2. Never try to overhaul the equipment or replace the “Air Refresher” filter yourself, as

it could cause a serious accident. FINAL NOTE Service your Regulator often- your personal safety and the mechanical integrity of your regulator depend on it. water is an especially bad environment for regulators as the chlorine chemically deteriorates the neoprene rubber components.

3. Regularly inspect the sintered filter in the inlet port of the first-stage. If it is

discolored or corroded, replacement by trained personnel is required. Also, at this point, the entire regulator may need a general overhaul with replacement of all soft seals and non-reusable components. Rust or aluminium oxide (grey powder) deposits on the sintered filter are usually an indication that salt water has entered the air cylinder and caused internal corrosion. At this time you air cylinder(s) should be internally inspected by a qualified and competent service control and then cleaned, or hydrostatically tested as required.

4. Do not disassemble your regulator. There are no adjustments which can or need

to be carried out by the user. Take the regulator to a qualified TUSA dealer or service facility for service. Ensure that only original parts are used to service your regulator.- 28 - Regulators
