DIVATOR DP1 comprises an automatic shuttle valve, low air warning whistle, pressure gauge, adapt-
er hoses for air supply cylinders and a connection to the high pressure air lifeline hose for the diver.
The connections to the air supply sources are suitable for both 200 and 300 bar (2900 and 4350 psi)
pressure "DIN" fittings.
“OPEN” tag Vent handle BeltCarbine hook
The following accessories are included with the DP1 Divator Surface Supply:
• “OPEN” tag Used to identify which air supply cylinder that is currently in use.
• Vent handle Used for protection of the high pressure air lifeline hose ends when stowing,
for flushing the high pressure air lifeline hose with fresh air before diving
and for rapid venting of the high pressure air lifeline hose after diving.
• Carbine hook Used to anchor the high pressure air lifeline hose to the belt.
• Belt Used for ergonomic attachment of the high pressure air lifeline hose to the
diver.
When the supply pressure falls to 55 bar (800psi), the warning whistle sounds and the air supply source
must be changed by opening the unused supply cylinder.
The shuttle valve automatically switches to the higher pressure cylinder, sealing off the previously
used supply cylinder, this enables the recently used adapter hose to be vented and the supply cylinder
to be replaced.
The pressure gauge displays the pressure of the cylinder currently in use.

With the adapter for two divers (optional) the Divator DP1 is enabled to supply air for two divers
simultaneously, as with the version for one diver, these divers will have a surface supply unit that is
self-compensating for depth variations. The unit will also have the advantage that it is possible to have
two divers at different depths, using the same cylinder supply source.

The Divator DP1 Surface Supply has been approved with an air supply hose up to 120 meters (396 feet)
in length for a maximum depth of 50 m (164 feet).
The high pressure air lifeline hose is attached to the diver with a quick-connection on the P+ regulator,
it attaches to the diver's manifold on the Divator regulator . The quick-connection has a locking ring
and should be secured when diving.
The other end of the high pressure air lifeline hose is attached to the surface unit with a "DIN" coupling
that is tightened by hand. The pressure in the high pressure air lifeline hose varies between 300–0
bar (4350–0 psi), depending on the air supply pressure.
1.4.1 HIGH PRESSURE AIR LIFELINE HOSE
The high pressure air lifeline hose has relieving loops and bend protectors at both ends, these protect
the hose couplings from stress.
The diver and attendant are both responsible for securing the high pressure air lifeline hose. Assure
that the high pressure air lifeline hose does not get kinked or severely bent . This is very important
and must be carefully checked.
The maximum work pressure of the hose is 300 bar (4350 psi) and the burst pressure exceeds 1500
bar (21760psi).
The high pressure air lifeline hose has been pull tested to 9000 N (900 kg). In addition it is CE approved
by an independent body in accordance with the requirements of European Standard EN 15333-1-2008,
Respiratory equipment - Open-circuit umbilical supplied compressed gas diving apparatus - Part 1:
Demand apparatus.

11
The high pressureair lifeline hose including relieving loops, hose, belt and carabine hook is designed
to withstand the demanding requirements of operational diving. Use of the high pressure air lifeline
hose is subject to the normal operational procedures and precautions that apply to all diving
equipment. As such, care must be taken by users to ensure that it is not used improperly or damaged
during use. Examples of potentially damaging events include being pulled hard against an object,
bent in a sharp angle, cut or nicked, or subject to extreme force.
1.4.2 REGULATOR, P+
The P+ Regulator is attached to the end of the high pressure air lifeline hose and is connected to the
divers regulator. The P+ regulator will supply the diver with a higher secondary pressure 10±0.3 bar
(145±4.4 psi) than the regulator used for the DIVATOR SCUBA cylinder.
The P+ regulator will automatically compensate the secondary pressure for depth variations done by
the diver and no continuous adjustment is needed by the surface attendant.

1.5 DIVATOR REGULATOR OPTIONS
The DIVATOR MKII REGULATOR is available in two versions. The standard version is the DIVATOR
MKII 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 breathing
resistance warning is provided in both the SCUBA and DP1 Surface Supply configurations.
The optional version is the DIVATOR MKII Regulator with Bail Out Valve. This version provides an
active breathing resistance warning only in the DP1 Surface Supply configuration when surface sup-
ply pressure is lost.
The DIVATOR MKIII REGULATOR is designed with dual first stage regulators integrated into one
unit. Therefore it becomes redundant and has an easy-to-use transition between reserve air or bail-out
mode with a “Pull for air”-solution. When used with DP1 the regulator is in "Closed" mode. The MKIII
Regulator is equipped with a surface supply inlet port for the DP1.
The following is an overview of the available regulator options and their characteristics.

** The DIVATOR MKII Regulator with Bail Out Valve is intended for applications where the diver needs completely
full SCUBA cylinders for his ascent, in the event 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.
1.5.1 DIVATOR MKII REGULATOR WITH RESERVE VALVE
This is the standard regulator for use with both the SCUBA and DP1 Surface Supply configurations.
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 to 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 DP1 Surface 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).

13
When using the DIVATOR DP1 Surface Supply, if the surface air supply is interrupted air will be taken
from the diver's SCUBA cylinders. The diver will receive active breathing resistance warning when
the DIVATOR SCUBA cylinder pressure has dropped to approximately 65 bar (940 psi).
1.5.2 DIVATOR MKII REGULATOR WITH BAIL OUT VALVE
This regulator is identified with a yellow "Bail Out" tag on the high pressure gauge hose. The Divator
MKII Regulator with Bail Out Valve warns the diver when the 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 MKII Regulator with Bail Out Valve and connected to the DIVATOR
DP1 Surface Supply, the Bail Out Valve lever should be in the upwards position. If the surface 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 cylinders 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 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.
CAUTION! Always ensure that the Regulator Bail Out Valve lever is in the up position prior to and
during surface supply diving.
1.5.3 DIVATOR MKIII REGULATOR
The regulator unit comprises two pressure regulators in a connecting pipe with a reserve valve. The
primary pressure regulator has two hoses connected. One of them feeds the primary breathing hose with
its primary breathing valve regardless of whether it is connected to a full-face mask or a mouthpiece.
There is a quick coupling on the hose that interacts with the external Divator DP1 Surface Supply. The
other hose is intended for inflating dry-suits (Optional).
The secondary pressure regulator has two hoses connected. One of them feeds the secondary breathing
hose (the octopus hose) with its octopus breathing valve. The other hose is intended for Divator BCW,
buoyancy compensating vest (Optional). The regulator unit is connected to the cylinder valve with a
coupling that is tightened by hand. The pressure in the air cylinders can be controlled on the pressure
gauge, which is connected to the regulator with a high-pressure hose.
When using the Divator MKIII regulator in SCUBA configuration the CDR handle (Closed, Dive, Re-
serve) is automatically drawn to “dive” mode when the air pressure is let on. When the diver reaches
the 60 – 70 bar (870 – 1015 psi) level he receives a breathing resistance, and by “pulling for air” on the
CDR handle, he pulls the handle to “Reserve” position and can breathe the remaining air pressure in
his cylinder pack. The dive should now be terminated!
When using the Divator MKIII regulator in Divator DP 1 Surface Supply configuration the CDR handle
is pushed to “Closed” position and thereby blocking the air from the worn cylinder pack to reach the
breathing hose, all breathing air for the diver will be taken from the Divator DP1 surface supply hose.
If the air from the Divator DP1 Surface Supply is interrupted the diver will receive a breathing resist-
ance warning and has to “pull for air” by pulling the CDR handle to “Dive” position and will then be
able to breathe air from the cylinder pack with a higher pressure remaining suitable for decompression
time or longer return times.
Note: All air consumption from the secondary pressure regulator, Octopus or BCW, will always be
taken from the worn cylinder pack.

2 PRE-DIVE PROCEDURES
2.1 HIGH PRESSURE AIR LIFELINE HOSE HANDLING
To avoid kinking of the supply high pressure air lifeline hose it is important to wind the hose in such
way that it is free from twisting (kinks). Kinks can result in flow restrictions.
The high pressure air lifeline hose should be wound up pressurized in figures of eight with a diameter
greater than 500 mm (> 1.5 feet) for each turn.
The diving attendant, or other responsible person, must ensure that the high pressure air lifeline hose
is handled in a way to reduce any possible twisting (kinking) of the high pressure air lifeline hose.
NOTE: The first time a high pressure air lifeline hose is used it can twist about four turns when its
pressurized. Therefore unwind the high pressure air lifeline hose and stretch it out to it's full length.
Pressurize the high pressure air lifeline hose to a minimum of 50 bar (725 psi) and wind it in the cor-
rect way. Release the pressure. Secure the high pressure air lifeline hose with rope or straps to hold it
together during handling and transport.
2.2 WINDING FRAME
Using a winding frame simplifies the winding of the high pressure air lifeline hose considerably.
The Winding Frame consists of four poles to wind the high pressure air lifeline hose around in the
figures of eight.
The high pressure air lifeline hose should be wound up pressurized in figures of eight with a diameter
greater than 500 mm (> 1.5 feet) for each turn.
When the high pressure air lifeline hose has been wound onto the winding frame and the pressure
in the hose has been released, it should be secured with the supplied rubber straps to hold it in place
during handling and transport.
The ends of the high pressure air lifeline hose should always be protected from water and dirt. There-
fore always connect the ends of the air lifeline hose to the supplied vent handle and make sure not to
sharply bend the air lifeline hose.

3.1 CHECK LIST
The check list below can be found on the inside lid of the Surface Unit.
Please note that the text on the check list
may vary depending on language region
or user requirements.
3.2 SURFACE ATTENDANT OPERATING PROCEDURES
1. Open the surface unit box. Place the box in such a position so that the pressure gauge is easy to
observe.
2. Check that the high pressure air lifeline hose is correctly wound from the last dive (see instructions
in the section Pre Dive Procedures).
3. Visually inspect the o-ring seals on the adapter hose cylinder connectors and on the surface unit
connection to the high pressure air lifeline hose. If they show signs of damage or they are missing,
replace with new ones.
4. Connect the high pressure air lifeline hose to the surface unit.
5. Secure the high pressure air lifeline hose in a safe way to a fixed object.
6. Connect one adapter hose to an air supply cylinder.
7. Connect the second adapter hose to a second air supply cylinder.
8. Close the vent valves on the adaptor hoses.

16
9. Open one cylinder valve. Check that the audible alarm sounds, and that the alarm stops after a
short period when the pressure increases. Check for leaks. Make a note of the pressure in the first
cylinder.
10. Close the first cylinder valve and open the vent valve to release some pressure. Close the vent valve.
11. Open the other cylinder valve. Check for leaks. Make a note of the pressure in the cylinder. Tag the
open valve with the "OPEN" tag.
12. Check that the pressure in the cylinder as shown on the gauge is sufficient to start your diving
operation.
13. Connect the vent handle to the P+ regulator and flush the hose with fresh air.
When the diver has completed his preparations, check the following:
11. Check that the cylinder valve on the DIVATOR SCUBA supply cylinder is completely open.
12. Check that the high pressure air lifeline hose is secured and correctly fastened to the divers belt.
13. Check that the P+ regulator with quick connector is correctly connected and locked with the locking
ring.
14. Check that the handle on the reserve valve is in the upright position (Divator MKII). Or for Divator
MKIII in the C (closed) position.
3.3 DIVER OPERATING PROCEDURES
1. Prepare the DIVATOR SCUBA according to the instructions in the DIVATOR SCUBA User Manual.
2. Open the cylinder valve on the DIVATOR SCUBA.
3. Check that the DIVATOR SCUBA cylinder pressure is greater than 270 bar (3920 psi). Close the
cylinder valve and breathe from the unit until the reserve valve becomes active as earlier described.
For Divator MKII Bail Out, or MKIII: check that the pressure in the cylinder is at least 270 bar
(3920 psi)
4. Open the reserve valve by bringing down the lever (MKII), or pulling the handle (MKIII) and con-
firm that you can breathe the reserve air.
5. Open the cylinder valve before connecting the P+ regulator.
6. Check that the high pressure air lifeline hose is pressurized. Connect the quick coupling on the P+
regulator to the Divator manifold and secure it with the locking ring.
7. Connect the eyelet (carbine hook) on the high pressure air lifeline hose to your belt.
8. Check that the reserve valve is in the upright position (Divator MKII), or in the C (closed) position
(MKIII), when the dive begins.
During the diving operation the surface attendant must observe the following:
• Check the pressure on the surface unit gauge frequently.
• Check frequently that the high pressure air lifeline hose does not kink.
• Be ready to switch to the second air supply cylinder when the surface unit gauge reaches 55 bar
(790 psi), or latest when the audible alarm sounds.
• If necessary, plan for connection of further air supply cylinders.

17
WARNING! If the high pressure air lifeline hose is connected to the diver and dived without being pres-
surized the water pressure may become higher than the air pressure on the inside of the hose and
may partially fill the inside of the hose with water. If the surface attendant then realizes his fault and
pressurizes the hose, water could be supplied to the diver instead of air.
WARNING! If the high pressure air lifeline hose ever enters the water not pressurized there is the pos-
sibility of water entering the hose.
WARNING! A pressurized high pressure air lifeline hose is not to be connected to a diver under water
under normal circumstances. See Warning above.

18
4 EMERGENCY PROCEDURES
4.1 LOW AIR SUPPLY PRESSURE, SURFACE
In an emergency the surface supply can be used until the air supply pressure has dropped to approxi-
mately 20 bar (290 psi).
WARNING! The high pressure air lifeline hose should never be re-pressurized during the dive if the
pressure in the hose has been lower than 10 bar (145 psi). Water may enter into the hose when depres-
surized and submerged, as stated earlier!
4.2 SURFACE SUPPLY FAILURE, DIVER
• If the diver has insufficient or no surface air supply, immediately change to bail out supply by actu-
ating the reserve valve lever (Divator MKII), or pull the handle to D (dive) position (Divator MKIII).
• After actuating the reserve valve function, abort dive! Start ascending towards the water surface.

19
5 POST DIVE PROCEDURES
1. Wind the high pressure air lifeline hose according to the instructions in section Pre-Dive Procedures.
2. Close the air supply cylinders valves and the cylinder valve on the bail out cylinder.
3. Depressurize the Divator DP1 Surface Supply by gently opening the vent valves on the adapter
hoses. To depressurize faster, use the purge button on the breathing valve or use the pressure vent
handle.
WARNING! When using the pressure vent handle, hearing protection should be used.
4. Disconnect the adapter hoses and park them in their parking connections.
5. Disconnect the high pressure air lifeline hose and connect both ends of the hose to the vent handle.
Make sure the air lifeline hose is not sharply bent.
6. Check that the high pressure air lifeline hose with couplings are free from damage, mud and chem-
icals.
