INTRODUCTION
Congratulations—and thank you—for choosing Apeks. All Apeks
regulators have been designed and manufactured with pride,
according to standards which meet or surpass all requirements for the
BS EN ISO 9001:2000 quality control system.
Your Apeks regulator is covered by Apeks’ Limited Lifetime Warranty
against defects in materials or workmanship. This warranty is only
extended to the original purchaser, and is not transferable. For more
information, be sure to read the warranty section of this manual, and
remember to save your sales receipts. Copies of these receipts must
be presented whenever obtaining warranty service.
Perhaps more than any other piece of diving equipment you will own,
your regulator’s function and performance relies greatly on the care
and maintenance it will receive, in addition to regularly scheduled
dealer service. 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.
Please read on to learn how you can obtain the maximum enjoyment
from your regulator, and maintain its like-new performance for many
years to come.
WARNING: Improper use or misuse of SCUBA equipment may
result in serious injury or death. Read and understand this
owner’s manual completely before diving with your Apeks
regulator.
NOTE: This product has been examined by Germanischer Lloyd
AG, Vorsetzen 32, D-20459 Hamburg, Germany, notified body for
PPE Identification number 0098.
NOTE: This product meets the requirements as laid out in the
directive relating to Personal Protective Equipment, Council
Directive 89/686/EEC modified by Council Directive 86/58/EC.

b. If it is not feasible to soak the regulator while it is attached to a
cylinder, it may be soaked unpressurised – provided that the dust
cap is securely sealed over the inlet, and the second stage purge
buttons are not depressed while the regulator is submerged or
wet.
NOTE: When soaking or rinsing an adjustable model regulator
unpressurised, check to ensure that the second stage inhalation
control knob is turned completely “in” (clockwise) to prevent
moisture from entering the valve and LP hose.
Therefore, if a regulator has had use with Grade E breathing air, it
should be returned to an authorised Apeks dealer for overhaul service
including hydrocarbon cleaning, prior to being put back into nitrox
service.
CAUTION: DO NOT loosen the first stage yoke screw, depress
the second stage purge button, or turn out the inhalation
control knob (if present) if the regulator is submerged
unpressurised. Doing so will allow the entrance of moisture,
and will require that the regulator be returned to an
authorised dealer for service.
If a regulator is to be used with EAN gas mixes over 40% then it must
be professionally converted to oxygen service.
4. While the regulator is soaking, move the IVS control switch (if
present) back and forth several times from the “MIN” (–) to the
“MAX” (+) settings. You may also turn the inhalation control knob
slightly back and forth—no more than 4 turns. This action will help
to loosen any salt or mineral deposits that may remain lodged in
the second stage.
5. After the regulator has been properly soaked, it is important to
rinse it vigorously by flushing the first stage ambient chamber
(non-environmentally sealed models only), the second stage
mouthpiece, and the openings in the second stage front cover with
a pressurised stream of water. This will remove any deposits of
salt and minerals that were loosened during soaking. If the
regulator is not pressurised, do not press the purge button
underwater. Moisture may otherwise enter the valves, which will
require that the regulator be returned to an authorised 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.
22
through a valve and regulator creates a cumulative effect where the
hydrocarbons build up over time along the internal passageways of
the equipment. When these hydrocarbons come in contact with highpressure oxygen enriched air, they can pose a very real hazard that
can lead to combustion.
Although second stage components are not exposed to high pressure
EAN, Apeks recommends that the same cleaning procedures be
followed for the complete regulator. This prevents the possibility of
cross contamination and guarantees the cleanliness of the entire
regulator.
NOTE: Apeks offers additional models and kits that are designed
and manufactured for use with enriched air nitrox where the
percentage of oxygen exceeds 40%. For information about these
models, consult your authorised Apeks dealer.
NOTE: In some countries the rules and regulations relating to
Nitrox use differ. Please contact your local distributor for details.

OVERVIEW OF FEATURES
The Apeks family of regulators consists of different models which
satisfy a wide range of diving interests; from entry level sport diving, to
advanced diving in more demanding and extreme conditions. By now,
your authorised dealer has already explained to you the specific
features that your particular model offers, and you have made your
purchase after comparing the benefits of these features to your
personal diving needs and interests. Be sure to review this section to
learn more about your model’s features and how to obtain the
maximum benefit from using them.
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 desensitise your regulator’s opening effort
at times when you are not breathing from it.
Integrated Venturi System
All Apeks second stages are equipped with a
unique integrated venturi system (IVS)
control switch. The IVS switch,
located on the opposite side to
the hose connection of the
second stage, controls the
venturi assist to reduce sensitivity
to freeflow at the surface and
provide maximum airflow at depth.
Whilst diving set the switch to plus (+)
to achieve maximum venturi assistance
for easier breathing.
8
CAUTION: Be careful when removing the first stage from the
cylinder valve to ensure that moisture does not enter either
the inlet opening of the first stage or the opening of the DIN
valve.
5. With the cylinder valve facing away from you, open the valve
slightly to 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 opening of the DIN valve to prevent the entrance of
moisture or debris.
Care & Maintenance
It is important to provide the proper preventative maintenance in order
to ensure the best possible performance and maximum life of your
Apeks Regulator. The following maintenance procedures should be
performed 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 is
important to wipe or blow the dust cap completely dry, and then
fasten it securely over the first stage inlet fitting. This is critical to
prevent the entrance of moisture into the first stage.
2. As soon as possible after diving, the regulator should be rinsed
thoroughly with fresh water while it is attached to a cylinder and
pressurised with air.
3. Rinsing alone, however, will not sufficiently clean the regulator. To
clean the regulator as thoroughly as possible, it is necessary to
soak it in warm (not over 50ºC / 120°F) fresh tap water for at least
one hour.
a. The preferred method is to attach the regulator to a charged
SCUBA cylinder, open the cylinder valve to pressurise the
regulator, and thoroughly soak both the first and second stages.
Pressurising the regulator will effectively prevent the entrance of
moisture and/or contaminants into the regulator while it soaks.
21
necessary to keep the interior of the regulator clean and the
percentage of oxygen below 40% along with the slow opening of the
cylinder valve (for regulators over 40% oxygen please see page 6).
To attach a yoke-style first stage to the
cylinder valve, follow these
steps:
1. Partially unscrew the yoke
screw of the first stage
regulator so that the dust
cap can be removed from
the air inlet.
2. With the cylinder valve facing
away from you, release a
small amount of air from
the cylinder by turning the
hand-wheel anti-clockwise
to open the valve only
slightly. When air is heard
exiting, immediately close the valve. This
will clear any moisture or debris that
may be inside the cylinder valve outlet
opening. 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. While holding the first stage in place, turn the yoke
screw clockwise. Ensure that the yoke screw mates into the small
dimple on the backside of the cylinder valve, and tighten fingertight only - do not over tighten.
4. If a submersible pressure gauge is attached to the first stage,
ensure that the gauge is facing away from you. Pressurise the
regulator by slowly turning the cylinder valve handwheel anticlockwise. Continue to turn the valve handwheel anti-clockwise
until it is fully open, and then turn it back 1/2 turn.
12
6. With the IVS lever set to (–) depress the purge button momentarily
to blow out any dust or debris which may have entered the second
stage. Release the purge button and listen to ensure that the
second stage does not continue to flow any air after the purge
button is released.
7. Inhale slowly and deeply from the regulator several times. The
regulator must deliver enough air for you to breathe easily without
noticeable resistance.
8. Check to ensure that the submersible pressure gauge is
displaying an accurate measurement of the air pressure inside the
cylinder.
9. Check to ensure that the IVS control switch is set to “MIN” (–). If
present, gently turn the inhalation control knob completely “in”
(clockwise), only until it stops. Do not apply excessive pressure.
These settings will help to minimise any loss of your air supply
during entry or while making a long surface swim. Adjustments
can be made below the surface.
During the Dive
When you are ready to submerge, place the
second stage in your mouth and set the IVS switch in the plus (+)
position. If present, turn the inhalation control knob out
(anti-clockwise) until the regulator breathes comfortably without
leaking or being undesirably sensitive.
As you descend, you may want to turn the inhalation control knob
further out to make breathing easier. This will be particularly true on
deep dives where the air density increases.
17
2. Position the first
stage near the
cylinder valve so that
the LP hose of the
primary second
stage will be routed
over the desired
shoulder. Thread the
first stage DIN
connector into the cylinder valve and
tighten the handwheel by hand until it
is lightly snug. DO NOT use tools
to tighten.
3. If a submersible pressure
gauge is attached to the
first stage, ensure that the
gauge is facing away
from you. Pressurise the
regulator by slowly
opening the cylinder
valve handwheel. Continue to turn the cylinder valve handwheel
until fully open, and then back 1/2 turn.
4. Listen near the first stage to check for any leakage. If leakage is
detected, immerse the first stage while pressurised to determine
the source.
5. If leakage has been detected, follow the procedure for removing
the regulator from the cylinder valve on page 20. 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.
If leakage persists, return the cylinder and regulator to an
authorised dealer.
14
DIN to Yoke Converter
For regulators which may be used back and forth between Yoke and
DIN connections, Apeks offers a convenient DIN to Yoke converter.
First, obtain factory prescribed installation of the DIN connector
through an authorised dealer. Then, simply attach the converter to
connect your regulator to a yoke valve.
WARNING: Adaptors from yoke 1st stage to a DIN cylinder
valve must never be used. This would allow a greater working
pressure to be used than the yoke connector is designed to
take.
