• 2 LP outlets (3/8”) are available on each cover. They can be used to connect
breathing/octopus valves, dry suits, BC hoses or any additional LP hoses.
HP connection
• The regulator has 2 HP outlets (7/16”). They can be used to connect a
pressure gauge, the Divator HUD or other HP devices.
DP1 connection
• The DP1 connection is added to the top cover of the RS4 regulator to
connect to the P+ regulator of the Divator DP1 surface supply system.

Preparation
The RS4 SCUBA can be used in different configurations. Follow this chapter in
applicable parts.
Adjusting the Divator RS4 before the first use
Adjust the RS4 into a mode that suits your SCUBA configuration before the first
dive. Use the included 2 mm (5/64 inch) hexagonal (Allen) key.
1. Turn the screws anti-clockwise maximum 1 turn until it is possible to turn
the cover(s).
2. Turn the cover(s) into desired position.
3. Tighten the screws until the cover(s) become locked in their position(s).
4. Make sure that the screws are tightened evenly.
5. Traditional regulator hose mounting.
6. Parallel regulator hose mounting.

ENGLISH

Assembling the Divator RS4 on the cylinder
Assemble the RS4 regulator onto the high pressure outlet on the cylinder,
either in the “parallel” mode or in the traditional “standard” SCUBA mode (as
seen on images).
Attaching a device to the second high pressure
outlet
It is possible to attach a HUD or other HP device to the second high pressure
outlet fitted with a parking plug. This procedure must be performed by an
Interspiro certified service technician according the RS4 service manual.
Attaching and directing hoses on Divator BC use
Installation of hoses must be made by an Interspiro certified service technician
according the RS4 service manual.
RS4

Connecting the breathing hose
1. Connect the breathing hose to the full face mask (or mouthpiece) by
tightening it fingertight.
2. If an over pressure mask is fitted, close the lever on the breathing valve.
Connecting the inflation hose
1. Put the inflation hose for the BC over the left shoulder along the
corrugated inflation hose and connect it to the power inflator.
RS4
13
ENGLISH

2. Adjust the hose length so that both hoses are parallel.
Connecting the octopus breathing hose and
valve
1. Connect the hose to the octopus breathing valve by screwing it on finger
tight. Close the Lever on the octopus breathing valve.
2. Make sure the hose is held in place and that there are no protruding parts
that can get stuck in anything.
Attaching the RS4 regulator pressure gauge
Fasten the elastic cord with hook (attached on the pressure gauge) on a
suitable D-ring on the BC. Make sure it is easily accessible during the dive.
RS4
14

Connecting the Divator DP1 hose
1. Connect the RS4 quick connector for DP1 to the DP1 P+ regulator.
2. Tighten the locking ring fully. Loosen it a quarter of a turn.
3. Connect the DP1 surface supply hose with the hook to the diving
apparatus. For further instructions see the DP1 surface supply user
manual.

ENGLISH

Pre-dive procedures
Overall check
1. Make sure that the RS4 regulator is clean and free from sand and/or
debris from previous use.
2. Inspect the regulator to detect if it has any signs of damage. A damaged or
defective regulator must be replaced or repaired by an Interspiro certified
service technician.
3. Check all hoses by pulling and bending them while inspecting for damage,
cracks and discolouration. If the high pressure hose to the pressure gauge
is found to be defective or damaged, it must be replaced by an Interspiro
certified service technician.
4. Check that the protective band is attached to the relief valve otherwise
replace it with a new protective band (part number 346 190 053, 10-pack).
WARNING
The air loss caused by a break in the dry-suit hose is just as
great as that caused by a break in the breathing hose.
The RS4 regulator has a restrictive orifice in the high pressure hose that limits
the air flow to the pressure gauge. The restriction protects the user and the
equipment if the hose burst.
Checking O-rings
O-rings that are exposed to sunlight, salt water, chemicals (including mild
detergents), and ozone suffer ageing and may become defective.
1. Check all visible O-rings.
2. Replace all cracked or damaged O-rings.
RS4
16

WARNING
If it is a DIN connection, tighten the cylinder valve completely
to prevent the o-ring on the regulator connection nipple to
come off.
If using a DIN connection and the O-ring on the regulator connection nipple
comes off: Put a new O-ring (part number 336 190 272, 10-pack) on the nipple
by pushing it in place.
Leakage and function test of the Divator RS4
regulator
1. Assemble the diving apparatus.
2. If using the primary breathing valve with safety pressure lever, make sure
that the safety pressure lever is in closed position.
3. Open the cylinder valve slowly and observe the pressure gauge. Check
that the pointer moves normally and smoothly. If the pointer moves
irregularly or not at all, the pressure gauge is faulty. When the cylinder
valve is fully open, then close it a quarter turn.
4. Check the pressure gauge to make sure that there is enough air pressure
in the cylinder for the planned dive. Interspiro recommends that the
cylinder should be full before every dive.
5. If using a BC and/or a dry-suit. Check that they can be inflated by
activating the inflation function. Also check that the dump valves are
functional.
RS4

ENGLISH

6. 1. If using a primary breathing valve with safety pressure, turn the safety
pressure lever to the open position. Check that a strong flow of air is
heard. Reset the safety pressure lever to the closed position.
2. If using a primary breathing valve without safety pressure, press the
purge button on the breathing valve. Check that a strong flow of air is
heard. Release the purge button.
7. If using an octopus breathing valve together with the primary breathing
valve, press the purge button on the octopus breathing valve. Check that a
strong flow of air is heard. Release the purge button. Close the locking
lever against the valve housing.
8. Test the entire system for leaks with the following steps:
• Close the cylinder valve.
• Wait for one (1) minute.
• Listen for leaks.
• Open the cylinder valve while watching the pressure gauge.
• Check that the needle does not rise by more than 10 Bar (145 Psi).
WARNING
If leakage is greater than the specified value, another
leakage has been located or if the equipment is found to
be defective or damaged, the equipment must be repaired
by an interspiro certified service technician.
9. Close the cylinder valve.
10. Check that the pressure gauge needle moves evenly while venting the
system by pressing the purge button (or turning the safety pressure lever
to open) on the breathing valve.

Checks during diving
1. Check the pressure gauge repeatedly to monitor air consumption.
Terminate the dive with ample air pressure to be able to return safely to the
surface or to the entry point of the dive.
2. Check for leaks or abnormal behavior of the RS4 regulator (small bubbles
will occasionally leave the anti-freeze device and are expected when
ascending, this is natural).
3. Check that optional equipment fitted to the RS4 regulator can be reached
and managed.
4. If using a DP1 surface supply together with the RS4 regulator, check that
air is not consumed from the worn cylinder. See the DP1 surface Supply
user manual for additional details.
WARNING
When diving with the RS4 regulator the diver´s only warning of
low air pressure is by repeatedly monitoring the pressure drop
of the pressure gauge.
WARNING
If using the DP1, the only indication that the diver has
switched from surface supply to the scuba cylinder (bail out) is
a decrease in the diver´s pressure gauge.

ENGLISH

Post-dive procedures
1. If connected, disconnect the DP1 hose.
2. Pressurize the RS4 SCUBA.
3. Rinse all parts of the RS4 SCUBA in clean water. If the equipment is very
dirty, use a brush and a neutral cleaning agent for extended cleaning.
4. Close the cylinder valve.
5. Press the purge button on the breathing valve to vent the regulator.
Venting may take as long as 30 seconds. The O-ring sealing between the
regulator and the cylinder valve may be damaged if it is removed when
there is pressure remaining.
6. Remove the RS4 regulator from the cylinder.
7. Allow all regulator parts to dry.
8. Blow any moisture out of the cylinder valve by opening the valve and
allowing air to escape for 1 to 2 seconds.
WARNING
Blow-off noise and pressure surges may cause hearing
damage. Always use ear protectors when filling and
emptying air cylinder packs.
9. Put the dust cover on the regulator connection nipple for protection.
10. If the equipment is faulty or damaged, it must be repaired or replaced by
an Interspiro certified service technician.
11. The equipment shall be thoroughly dried if it is to be stored in a bag/box for
more than a few hours.
