RG 5400 — Oxygen Decompression Regulator

• 
  NOTE: The Oxygen Deco Regulator is ONLY intended for use as a deco regulator. Do not attempt to use for a stage bottle / travel regulator.
• 
  NOTE: The Oxygen Deco Regulator is not intended for use deeper than 50ft (15m) on appropriate gas mix.

The Dive Rite Oxygen Deco Regulator is a compact, lightweight option for a deco regulator. Assembled in a clean room using all oxygen compatible materials and lubricants, this shallow water deco regulator can be used with higher concentrations of oxygen without the need for additional initial preparation.

An unbalanced piston DIN first stage gives ideal performance for a shallow water regulator. An OPV on the first stage provides an additional margin of safety in the event of a first stage failure. A single HP port is used for a 1” diameter button gauge.

The XT2 second stage is a pneumatically balanced second stage with Venturi assist to provide consistent gas pressure delivery for smooth inhalation. User adjustability on the second stage lets divers tune the inhalation setting to match personal preference. An orthodontic mouthpiece reduces jaw fatigue on longer deco obligations. A 40” green low-pressure hose and green faceplate on the second stage come standard to indicate oxygen use.

RG 5400-DRYSUIT — Drysuit Inflation Regulator

• 
  NOTE: Do not attempt to use for drysuit inflation at depths exceeding 330ft (100m).
• 
  NOTE: Do not attempt to use as a breathing regulator without proper cleaning and service. Failure to do so can result in serious personal injury or death.
• 
  NOTE: If used for breathing service the RG5400 is ONLY intended for use as a deco regulator. Do not attempt to use for a stage bottle / travel regulator. It is not intended for use deeper than 50ft (15m) for breathing gas.

Compact in size and lightweight, the Dive Rite Drysuit Inflation Regulator is the perfect fit on an argon / drysuit inflation bottle. Weighing in at just 12.4 oz (351.5 g), and measuring just 3.5” x 1.25” (8.9cm x 3.2cm), this regulator will not add unnecessary bulk to a drysuit inflation configuration. The first stage is equipped with an OPV to give an additional margin of safety in the event of a first stage failure. Drysuit inflation hose included.

XT2 Second Stage Regulator

• Pneumatically balanced downstream design gives consistent gas pressure for easy inhalation
• Venturi assist reduces work of breathing
• Glove friendly dive/pre-dive lever avoids free flows at the surface
• Adjustable design helps diver fine tune cracking pressure so breathing resistance matches diver personal preference
• Deflection ring works to maximize performance while deterring free flow
• Orthodontic mouthpiece reduces jaw fatigue on long dives
• Internal parts are Teflon coated for cold-water use
• Oxygen compatible O-rings and lubricant used throughout

Diver must use oxygen compatible materials, keep the regulator clean from contaminants during assembly and use and open the tank valve slowly.

Regulator Set Up

Attaching Hoses

There are two high-pressure and five low-pressure ports on the first stage. The high-pressure port is for attaching a pressure gauge. The low-pressure ports give divers ultimate flexibility in streamlining and routing for the inflator hose and second stage regulator configurations.

• 
  Do not try to connect a low-pressure hose to a high-pressure port or vice versa. Do not open a cylinder valve unless you are certain that all hoses are correctly attached.

• 
  NOTE: The turret-port base is slightly convex and slotted on each side to accommodate an 11/16 wrench for securing the turret while loosening the LP hose. This makes it easy to change the hose without concern of loosening the turret.

To Attach a Hose:

1. Check that the hose O-ring is in place
2. Line up the hose connector with a port
3. Hand-tighten the hose to the regulator. Tighten further using the appropriately sized wrench. Do not over tighten.

Using the External Adjustment Knob

Turning the adjustment knob clockwise increases spring tension, making it more difficult for the valve to open. This helps to reduce the tendency to free-flow in strong currents.

Turning the knob counter-clockwise decreases spring tension, making the valve easier to open. This reduces breathing resistance, but can increase the tendency to free-flow.

You will want to try various settings of this knob during your first few dives to find the right position for you. The best practice is to set the regulator so that it breathes easily, short of free flowing.

Adjusting the knob for the maximum breathing resistance does not reduce the amount of air you breathe from your cylinder. It may actually cause you to use more air because your diaphragm has to work harder to compensate for the resistance.

Using the Venturi Dive/Pre-Dive Switch

The dive/pre-dive switch controls a venturi flow valve located within the second stage of the regulator. When in the pre-dive position (pushed forward), this valve decreases the likelihood of free-flow when not in use. The dive position (back, toward mouthpiece) decreases breathing effort and improves regulator performance.

To Set the Venturi Switch:

1. Set the switch to the dive position before each dive.
2. Set the switch to the pre-dive position when the regulator is not in use in or out of the water.

XT4 Secondary Micro Spring Adjustment

The XT4 second stage offers an additional adjustment for fine tuning your regulator. The micro spring adjustment independently adjusts the spring preload and cracking pressure. To adjust, first turn the external adjustment knob fully counterclockwise to its maximum setting. Then, holding the external adjustment knob, use a 5mm Allen wrench to turn the micro spring adjustment located inside the knob. Turning this adjustment clockwise increases spring preload and cracking pressure. If you are unsure of how to properly set this adjustment, contact your authorized Dive Rite regulator technician.
