Before use

Technical description
DIVER DP1 is a surface supply diving system with an operating pressure of up to 75 bar or up to 300 bar, depending on the version. The pressure in the supply hose varies between 300–55 bar or between 75-55 bar. It has two high- pressure supply cylinder connections, each one connected to a high-pressure cylinder supply. A shuttle valve automatically switches to the supply with the highest pressure and the supply pressure is shown on the pressure gauge.
When the supply pressure drops to 55 bar, the warning whistle sounds and the supply must be changed by opening the second supply.

Surface attendant operating procedures
A check list 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.

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 supply hose is correctly wound from the last dive (see section “Winding the supply hose”).
3. Visually inspect the O-ring seals on the adapter hose cylinder connectors and on the surface unit connected to the supply hose. If they show signs of damage or they are missing, replace them with new ones.
4. Connect the supply hose to the surface unit.
5. Secure the supply hose in a safe way to a fixed object using the eyelets.
6. Connect one adapter hose to a full supply cylinder.
7. Connect the second adapter hose to a second full supply cylinder.
8. Close the vent valves on the adaptor hoses.
9. Open one cylinder valve. Check that the audible alarm sounds and that the alarm stops after a short period when the pressure increases above 55 bar. Mark the open cylinder valve with the Open tag.
10. Check that the pressure in the cylinder as shown on the gauge is sufficient to start your diving operation.
11. Connect the vent handle to the P+ regulator and flush the hose with fresh air.
12. Check that the cylinder valve on the Divator SCUBA cylinder is completely open (hand wheel fully opened and then turned back a ¼ of a turn).
13. Check that the supply hose is secured and correctly fastened to the divers belt using the relieving loop and carabiner.
14. Check that the DP1 is pressurized.
15. Connect the quick coupling on the P+ regulator to the Divator SCUBA and secure it.

NOTICE
With the lifeline correctly connected, it is possible to pull the supply hose in any direction without straining the connection. All strain must be absorbed by the relieving loop and the carabiner.

Warning
If the supply hose is connected to the diver and dived without being pressurized 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 supply hose ever enters the water not pressurized there is the possibility of water entering the hose.
Warning
A pressurized supply hose is not to be connected to a diver underwater.

Operating procedures

1. Frequently check the pressure on the surface unit gauge.
2. Frequently check that the supply hose does not kink.
3. Be ready to switch to the second air supply cylinder before the surface unit pressure gauge reaches 55 bar.
4. If necessary, plan for the connection of further air supply cylinders.

Switching supply cylinder

1. Open the cylinder that has full pressure.
2. Check that the pressure is rising on the pressure gauge and that the whistle stops sounding.
3. Close the cylinder with low pressure and depressurize it through the venting valve.
4. Move the “OPEN” sign to the open cylinder.
5. Replace the empty cylinder with a cylinder that has full pressure.

Extreme conditions
Diving in extreme conditions, such as diving in cold environments, requires special training, planning and preparation.
Refer to the separate instruction with document number 34228, available on the download section of interspiro.com, for more information.
Emergency procedures
Low air supply pressure, surface

• In an emergency, the surface supply can be used until the air supply pressure has dropped to approximately 20 bar .

Warning
The supply 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 depressurized and submerged.

Surface supply failure, diver

• If the diver has insufficient or no surface air supply, immediately change to bail out supply.
  After activating the reserve valve function, abort dive! Start ascending towards the water surface.

After use

Disconnection

1. Disconnect the DP1 supply hose from the Divator SCUBA while it is pressurized.

2. Close the DP1 cylinder valve on the DP1 supply cylinder.

3. Vent the supply hose by using the vent handle (not through the venting valves on the adapter hoses).
   Warning
   Always use hearing protection when discharging high-pressure air.

4. Protect all couplings with dust covers or park them in their parking connections.

Cleaning

1. Clean the house, belt, and carbine hook with a cleaning solution consisting of 10 % soap and fresh water.
2. A degreasing agent can be used to clean badly polluted parts. Before using such an agent contact the manufacturer of it to check if it is suitable in combination with the type of materials used in the Divator DP1 Surface Supply. Follow the instructions received from the manufacturer.
3. Mechanical parts must be carefully cleaned so that sand or dust are removed from the moving parts.

NOTICE
Remember to keep the surface supply pressurized when washing in soap and water.

Visual inspection

1. Inspect the eyelets at both ends of the supply hose to ensure that there is no damage or chemical deterioration.
2. Check the quick coupling, make sure that the locking sleeve is easily operated and that it is free from sand and dust.
3. Inspect all hoses.
   If there is any suspicion of chemical or mechanical damages (such as overload) follow the instructions in chapter “Full hose inspection”.

Full hose inspection

1. Make sure that there are no chemical or mechanical damages (such as overload) on the hose.
   Inspect along the whole length of the hose that there are no:
   • cuts
   • scratches
   • kinks or traces of kinking
   • or chemical damages.

2.  Make sure that the metal tubes in the ends of the hose are undamaged and without cracks and/or rust.

3. Replace damaged hoses.

Anti-freezing unit
Version RS4 P+ / Pro P+

1. Check that the anti-freezing diaphragm is undamaged.

2. Check that the knob in the center is undamaged and in place.

3. Check that the rubber ring on the P+ regulator relief valve does not have

Version MKII P+

1. Use the screwdriver. Remove the hose clamp.

2. Remove the anti-freezing cover.
   Remove the anti-freezing cap.

3. Make sure that no water has entered the regulator.
   If there is water in the regulator, blow compressed air into one of the holes until the regulator is completely dry inside.
   

4. Lubricate the anti-freezing cap on the inside edge.

5.  Make sure to assemble it evenly along the edge. Make sure that the cap is filled with air.

6. Assemble the anti-freezing cover.
   Make sure that the plastic halves do not pinch the anti-freezing cap.

7. Assemble the hose clamp and the cover in the direction shown in the image.

8. Assemble the hose clamp.
   Tighten the hose clamp until the cover is locked but still possible to turn without the anti-freezing cap turning together with it.
   

Winding the supply hose
To avoid kinking of the supply 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 supply hose should be wound up pressurized in a figure of eight with a diameter greater than 500 mm (1.5 feet) for each turn. Alternatively, the hose can be wound in a ring, but then it must be turned in the upper and lower turns when it is wound.
When the supply hose has been wound and the pressure in the hose has been released, it should be secured to hold it in place during handling and transport. The ends of the supply hose must always be protected from water and dirt by connecting the ends of the supply hose to the supplied vent handle. Deviator hose winding frame
The winding frame consists of four poles to wind the supply hose around in the figures of eight. Wind according to images depends on how long the hose is.
If the hose is 60 m or less wind it according to image 1, if it is longer, wind it according to image 2. For more detailed instructions see document 96878. Holdall
There are also a bag with two poles that can be used to wind a supply hose that is up to 60 m long. Wind the hose in the figure 8 around the poles in the bag.

Leakage test
If the unit fails the leakage test it must be repaired before use.
Preparation

1. Prepare two gas cylinders filled to the same pressure, above 200 bar.
2. Connect the supply hose to the surface unit.
3. Connect the adapter hoses to the cylinders.

Test

1. Pressurize the unit by opening both cylinder valves, wait for 3 minutes to let the pressure stabilize.

2. Tap on the pressure gauge.

3. Close both cylinder valves and check that there is no visible pressure drop during 30 seconds.

4. At side A:
   1. Open the vent valve and wait a few seconds to release the pressure in
   the adapter hose.
   2. Check that there is no audible leak at the cylinder connection.
   3. Close the vent valve and open the cylinder valve.

5. At side B:
   1. Open the vent valve and wait a few seconds to release the pressure in the adapter hose.
   2. Check that there is no audible leak at the cylinder connection.
   3. Close the vent valve.
