• The DOT and CE approved DIVATOR LITE cylinder packs are available in two congurations. The
DIVATOR LITE 323.4 is a 3.4 liter 300 bar (75 cubic feet 4350 psi) twin cylinder pack and the DIVATOR
LITE 326.7 is a 6.7 liter 300 bar (140 cubic feet 4350 psi) twin cylinder pack.
The cylinder pack consists of two cylinders mounted together with two stainless steel straps. The cylinders
have one common valve mounted to one cylinder, the cylinders are interconnected with a cross over tube
that is protected by the carrying handle.
The DIVATOR Lite cylinders are fully composite cylinders with plastic liners wrapped with carbon and
glass ber.
The cylinder handwheel must be pushed in and turned to close the cylinder valve. This prevents inadvertent
closing of the valve.
A handle used for carrying of the cylinder pack also protects the crossover tube from damage.
The safety disc on the cylinder pack is designed to rupture at a pressure of 450±50 bar (6525±725 psi).
Impacts to the cylinder pack may cause skewing and/or damage which may weaken the unit. Skewing or
damage must be checked and corrected. Carelessness when handling the cylinder pack with its weight tted
may result in deformation of the spacing rod or weight shaft.
For charging of cylinders, see chapter 8 Filling Procedures.

3.5.1 MKII Regulator, First Stage
• The pressure regulator is a downstream piston-type regulator with an extremely high ow capacity. The
regulator reduces the primary cylinder pressure of 300 bar (4350 psi) to a dynamic secondary pressure of
7.5 bar (109 psi). It is a pressure-balanced piston counter ow regulator. The effect of the balancing is that
the reduced secondary pressure is stable and is not affected by pressure variations in the air supply (primary
pressure).
The regulator includes a four port swivel that provides convenient air supply connections to the BCW, dry
suit and DIVATOR Octopus breathing valve. The high ow capacity ensures sufcient air to both the Pri-
mary and Octopus breathing valves down to 60 meters (198 feet) of sea water.
3.5.2 DIVATOR MKII Regulator Options
• The DIVATOR MKII REGULATOR is available in three versions. The standard version is the DIVATOR
Regulator with Reserve Valve. This version provides an active breathing resistance warning when the
SCUBA cylinder pressure reaches the reserve pressure of 65 bar (942 psi). This warning is provided in
both the SCUBA and DP1 Surface Supply congurations.
The rst optional version is the DIVATOR Regulator with Bail-out Valve. This version provides an active
breathing resistance warning only in the DP1 Surface Supply conguration when surface air supply pressure
is lost.
The second optional version is the DIVATOR MKII without Reserve Valve. This version can be seen as a
low cost alternative or the version to use if only active warning with HUD is requested.
The following is an overview of the available regulator options and their characteristics.

** The DIVATOR Regulator with Bail-out Valve is intended for applications where the diver needs completely
full SCUBA cylinders for his ascent, when he experiences a loss of surface supply air.
The Interspiro Bail-out regulator is not recommended for use in SCUBA (without surface supply) dives
because it does not provide an active warning when the diver’s SCUBA cylinders have reached the reserve
pressure level. The optional DIVATOR HUD provides a visible active warning that the SCUBA cylinders
have reached reserve pressure.

14
3.5.3 DIVATOR MKII Regulator with Reserve Valve
• This is the standard regulator for use in both SCUBA and DP1 Surface Supply congurations.
The diver gets an active breathing resistance warning when approximately 20 % of the SCUBA cylinder air
supply remains 60-70 bar (870-1015 psi). The warning occurs on the high end of this pressure range when
the air consumption rate is high. The breathing resistance warning is created by reducing the air supply at
the end of each inhalation. The inhalation phase will be shorter and shorter and will be repeated a number
of times until the valve becomes completely closed or until the reserve valve lever is actuated (pushed down).
When actuated, the reserve valve lever will be locked in the open position (down) thereby shutting off the
breathing resistance warning and making the reserve air volume available to the diver.
It is not possible to inadvertently or prematurely activate (push down) the reserve valve lever; it will
automatically reset itself (up position) until the air supply pressure has dropped below approximately 80
bar (1160 psi).
When using the DIVATOR DP1 Surface Supply, all supply air will be taken from the DIVATOR DP1
Surface Supply as long as the supply pressure is greater than 20 bar (290 psi) at a dive depth of 50 meters
(150 feet) or less. Note: The DIVATOR DP1 Surface Supply has a low air warning whistle that is activated
at 55 bar (790 psi).
When using the DIVATOR DP1 Surface Supply and the surface air supply is interrupted, air will be taken
from the diver's SCUBA cylinders. The diver will receive an active breathing resistance warning when the
DIVATOR SCUBA cylinder pressure has dropped to approximately 65 bar (940 psi).
3.5.4 DIVATOR MKII Regulator with Bail-Out Valve
• This regulator is identied with a yellow "Bail-Out" tag on the high pressure gauge hose. The DIVATOR
Regulator with Bail-Out Valve warns the diver when the air supply from the surface is interrupted. This is
a feature that can be required for decompressions that require more air than might be available when using
the standard Regulator with Reserve Valve.
While diving with the DIVATOR Regulator with Bail-Out Valve and connected to the DIVATOR DP1 Surface
Suppy, the bail-out valve lever should be in the upwards position. If the surface air supply is interrupted,
the diver will receive an active breathing resistance warning and must then actuate (push down) the lever
in order to switch to the SCUBA cylinder's air source. When actuated (pushed down), the bail-out valve
lever will be locked in the down position.
It is possible to push down the lever of the bail-out regulator prior to the active breathing resistance warning;
however, this action does not switch to the DIVATOR SCUBA cylinder air supply as long as there is pressure
from the DIVATOR DP1 Surface Supply. Note: the lever will not reset automatically like the Standard
Regulator with Reserve Valve version.
If the bail-out lever is pushed down prior to receiving the breathing resistance warning, and the surface
supply is then interrupted, the bail-out regulator will automatically switch from the surface supply to the
SCUBA cylinders without providing the diver with a warning.
DANGER! Always ensure that the regulator bail-out valve lever is in the up position prior to and during
surface supply diving.

15
3.5.5 DIVATOR MKII Regulator without Reserve Valve
The DIVATOR MKII Regulator without Reserve Valve includes all the same features of the DIVATOR MKII
Regulator with Reserve valve (see above) with the exception of the reserve valve feature. The DIVATOR
MKII Regulator without Reserve valve is best combined with the DIVATOR Heads Up Display (HUD) if
the user prefers to have a visual warning rather than a tactile warning.
3.5.6 DIVATOR Heads Up Display (HUD)
• The DIVATOR HUD is a warning light that activates when the DIVATOR SCUBA cylinders reach a
reserve pressure of 55 bar (800 psi).
The DIVATOR HUD can be mounted on any Interspiro DIVATOR Full Face Mask or breathing hose.
It is manually snapped onto the DIVATOR Full Face Mask frame without fasteners or tools.
The DIVATOR HUD is automatic and has no manual switches. When the SCUBA cylinders are either
empty or closed, the DIVATOR HUD is off. When the cylinder valve is turned on, the DIVATOR blinks
two or three times to verify that it is working properly. When the SCUBA cylinder air pressure drops to
55 bar (800 psi) the DIVATOR HUD begins to blink. The DIVATOR HUD blinks continuously until the
SCUBA cylinder air pressure drops to 10 bar (145 psi), at which point it automatically turns off.
The DIVATOR HUD is fail-safe against leakage. If inward leakage occurs, the light will blink continuously.
The DIVATOR HUD has an integral safety valve that safely vents in the event of over-pressure.
For additional information see DIVATOR HUD User Manual.

16
3.6 BREATHING VALVE
• The DIVATOR SCUBA Breathing Valve is available in three versions:
(1) Primary with safety pressure (2) Primary without safety pressure
(3) Secondary (Octopus) with locking lever without safety pressure
The primary breathing valves are available in either black or gray. The octopus breathing valve is only
available in black with a yellow shield ring.
The primary breathing valves are mounted to the face mask with a bayonet coupling. All three of the
breathing valves are demand breathing valves, supplying air only during inhalation.
The DIVATOR Breathing Valve is balanced and maintains extremely low breathing resistance at all diving
depths even if variations occur in the secondary pressure.
The breathing valve is also designed as a safety valve for the rst stage regulator. If the secondary pressure
from the rst stage regulator increases to approximately 14 bar (203 psi), the relief valve in the breathing
valve will open. This prevents over-pressurization of the secondary system components.
As an additional safety feature, in the inhalation channel there is a one-way valve to prevent water from
penetrating into the valve mechanism where it could freeze and cause the valve to stick in the open
position.

17
3.6.1 Primary Breathing Valve Parts (Safety Pressure)
1 Connection nipple 6 Locking ring
2 Non-return valve, inhalation channel 7 Shield ring
3 Bayonet coupling 8 Purge button
4 Diaphragm attachment 9 Safety pressure lever (Only on safety pressure version)
5 O-ring 10 Locking nut
• Interspiro recommends use of the DIVATOR Breathing Valve with Safety Pressure for diving in
contaminated water.
The DIVATOR Breathing Valve with Safety Pressure is designed to give a safety pressure of approximately
35 mm (1.5 inch) of water column in the mask in ambient air. The safety pressure is turned on automatically
when the user takes his rst breath in the mask. The safety pressure reduces the risk of inward leakage of
water (or air at surface) which is very important when diving in contaminated water. The safety pressure
in the mask is maintained irrespective of the diver's air consumption rate.
In the event that water enters the mask, the mask is easily drained by pushing the purge button of the breathing
valve. When the mask is taken off, the safety pressure lever on the breathing valve must be pushed in (shut
off) against the valve housing.
DANGER! DIVATOR Breathing Valve with Safety Pressure must not be combined with the DIVATOR
mouthpiece, due to the risk of uncontrolled free ow.

3.6.2 Primary Breathing Valve without Safety Pressure
• The DIVATOR Breathing Valve without Safety Pressure does not provide safety pressure during inhalation.
Otherwise, the performance is the same as the DIVATOR Breathing Valve with Safety Pressure.
A rubber sealing plug has replaced the safety pressure lever and other internal parts are different.
3.6.3 Secondary Octopus Breathing Valve
1 Locking Lever 3 Shield Ring
2 Mounting Clip
• The DIVATOR Octopus Breathing Valve is identied by the yellow shield ring and yellow mounting
clip. The octopus breathing valve is a non-safety pressure type and is equipped with a locking lever. The
locking lever locks the valve from possible inadvertent free-ow of air and should always be in the locked
(closed) position when not in use.

3.7 FULL FACE MASK
• The DIVATOR Full Face Mask is available in four versions:
Natural Rubber
(1) Black (2) Gray
(shown with optional
DIVATOR Hatch)
Silicone
(3) Black (4) Yellow
All DIVATOR Full Face Masks are available with an optional DIVATOR Hatch.
For additional information see DIVATOR HATCH User Manual.
The DIVATOR Full Face Mask is available in either natural or silicone rubber. Natural rubber is more
resistant to chemicals and more tear resistant. Silicone is more resistant to ozone, thermal and UV light
radiation. The silicone mask is slightly smaller and may t smaller faces better.
The rubber head harness has ve straps that are tightened and locked by stainless steel buckles. The wide
and soft sealing edge of the mask is pressed lightly against the face and follows the contours of the face,
giving an effective seal. The mask is designed to be used with diving communications.

20
3.7.1 Visor
• The visor is designed to minimize the volume of air inside the face mask to reduce the positive buoyancy.
If it is necessary to adjust the mask to a neutral buoyancy, weights are available which can be attached to
each side of the visor. The visor is close to the wearer's eyes which gives the user a wider eld of vision.
The sides of the visor have a matte nish to avoid optical distortions.
