Page 4: General Precautions & Warnings
■ Always pressurize the regulator gradually by opening the cylinder valve SLOWLY. ■ NEVER apply any type of lubricant to any part of the regulator or cylinder valve. ■ DO NOT apply any type of aerosol spray to the regulator. Doing so may cause permanent damage to certain plastic components, including the second stage housing. -
Page 5: Introduction
Before you dive with your new Apeks regulator, it is therefore important to read this manual in its entirety to become familiar with its features, as well as the correct procedures for setup, pre-dive inspection and post-dive maintenance. -
Page 6: Using Enriched Air Nitrox (Ean)
If it is your intention to use your new Apeks regulator with EAN (O to exceed 40%), it is imperative that you maintain the internal cleanliness of the regulator (see section on Care and Maintenance). If it is your intent to use the regulator interchangeably with breathing air, the breathing air should be oxygen-compatible or “hyperfiltered”... - Page 7 Therefore, if a regulator has had use with Grade E breathing air, it should be returned to an authorized Apeks dealer for overhaul service including hydrocarbon cleaning, prior to being put back into nitrox service.

Diver Changeable Exhaust system (DCE). Second Stage Hose Configuration Apeks XTX regulator range can be dedicated to either left or right handed use in conjunction with the RVS system (see page 11). The hose routing can be altered from right hand to left or from left hand to right by your Authorized Apeks Dealer. -
Page 9: Diver Changeable Exhaust System (Dce)
The exhaust diffusers can be easily and very quickly changed by sliding and locking the preferred set into place. Divers can now configure their own regulator exhaust diffusers for individual dive conditions or requirements. By pressing the securing button in the centre of the exhaust diffuser and at the same time sliding the diffusers apart, they can be removed quickly and easily. - Page 10 CAUTION! Ensure location grooves are free from dirt and debris. 3. Refitting the exhaust diffusers is carried out by sliding ONE diffuser at a time onto the case, once both diffusers are located on the case, squeeze the two diffusers together until you hear an audible “click”.

Page 11: External Second Stage Adjustments
External Second Stage Adjustments External adjustment features offer many advantages, including the ability to adjust your second stage regulator’s sensitivity as your diving conditions change. This can allow you to maintain peak performance throughout every dive, or to desensitize your regulator’s opening effort at times when you are not breathing from it. -

(DPV). You can use the inhalation control knob to tune your regulator to maintain its peak performance throughout the course of your dive, or you can leave it set in its mid-range position and dive with it as you would any non-adjustable second stage. -
Page 13: Egress Second Stage
Egress Second Stage The Egress is a low profile second stage suitable for use in all diving conditions, and can be used either way up due to its side exhaust and hose layout. Therefore the diver can use the second stage with the hose routed from either the left or right depending on personal... -

Your dealer can also answer any questions you may have pertaining to the information in this manual. If it is not possible to return your regulator and accessories to your Apeks Authorized Dealer, you may install the accessories yourself carefully performing the steps in the following procedure. -
Page 16: Attaching The First Stage To The Cylinder Valve (Yoke)
1. Check the second stage IVS/RVS control switch to ensure that it is set to the “MIN” (–) position prior to connecting your regulator to the tank. 2. If present, gently turn the inhalation control knob “in” (clockwise), only until it stops. Do not apply excessive pressure. - Page 17 Check the O- ring is still in place. 3. Place the first stage regulator over the cylinder valve so that the inlet fitting aligns with the O-ring of the cylinder valve, and the LP hose of the primary second stage will be routed over the desired shoulder.

(from contamination) are the ingredients that can cause combustion. This is why it is necessary to keep the interior of the regulator clean and the percentage of oxygen below 40% along with the slow opening of the valve. -

5. If leakage has been detected, follow the procedure for removing the regulator from the cylinder valve on page 24. If air was leaking between the first stage and cylinder valve, replace or re-seat the cylinder valve O-ring as needed and repeat the above procedure. -
Page 20: Diving With Your Regulator
DIVING WITH YOUR REGULATOR Before each use, it is important to perform a complete pre-dive inspection of your regulator. NEVER dive with a regulator that shows signs of damage or unsatisfactory performance until it has received complete inspection and service from an authorized dealer. -
Page 21: During The Dive
7. Inhale slowly and deeply from the regulator several times. The regulator must deliver enough air for you to breathe easily without noticeable resistance. -
Page 22: Diving In Cold Water
If these precautions are not taken, freeze-up can occur. It is possible for icing or freeze-up to occur, even with a regulator that has been specially designed for cold water use. It is therefore imperative to practice the correct cold... - Page 23 Excess water vapor can freeze, causing a freeflow condition, or blocking the flow of air entirely. 2. Protect your regulator from any contact with water until the moment that you are ready to begin your dive. 3. Protect your equipment from cold temperatures before the dive.
-
Page 24: After The Dive
AFTER THE DIVE NOTE: If fresh water is available, rinse your regulator completely before depressurizing it, and thoroughly dry the first stage and cylinder valve. This will help to prevent any contaminants from entering the regulator when it is removed from the cylinder. -
Page 25: Care & Maintenance
Pressurizing the regulator will effectively prevent the entrance of moisture and/or contaminants into the regulator while it soaks. b. If it is not feasible to soak the regulator while it is attached to a cylinder, it may be soaked unpressurized – provided that the dust... - Page 26 Moisture may otherwise enter the valves, which will require that the regulator be returned to an authorized dealer for service. 6. Wipe the regulator as dry as possible and hang by the first stage to ensure that all remaining moisture drains from the second stages.
