ATLANTIS TECH R60 2ND STAGE
These models are balanced demand valve second stage regulators - smaller and lighter
than most other primary second stages. They provide breathing gas as you demand it
with low inhalation resistance. Breathing eort is factory set to the average performance
level required by most divers.
They are provided with front-mounted purge buttons and orthodontically designed mouth-
pieces. They can be used as primary second stages or as an octopus.
NOTE: If this second stage is shipped from the factory specically as an Octopus, the
inhalation eort is set slightly higher to reduce sensitivity.

SERVICE PROCEDURES FOR THE TECH R60 ADJ
Before you begin disassembly of the regulator, test the rst and second stages for output
pressures 'work of breathing' and leakage. Pre-testing in this way will help the technician to
pinpoint any specic problems requiring repair.
SERVICE PROCEDURES FOR THE TECH R60 ADJ
The work area must be clean and well lit, with clean compressed air available to blow sand
and dirt from parts.
TOOLS REQUIRED FOR 2ND STAGE SERVICING
- 18MM HEX Wrench
- Adjust tool for second stage
- 2nd Stage Service Kit
- Clean Shop Rags
- Dow-Corning Compound 111 Silicone Grease or
- LTI Christo-Lube MCG 129
- IP Gauge
- O-ring picks
- Soapy spray
- Magnehelic Gauge
- Torque wrench
- Adjustable spanners
Use the 6” and 8” adjustable wrenches to loosen the hose nut from the COUPLING (12).
Remove the hose assembly from the second stage. Inspect the hose assembly for any cuts or
cracks, especially on the hose at the metal ferrules. If found, remove and discard. Check the
O-rings on each end of the hose. Clean, rinse, and blow-dry the interior bores of the hoses.
Replace the hose if any cuts or cracks are found.
Examine the condition of the mouthpiece. If it's in good condition you don't need to remove - it
can be re-used. Remove the mouthpiece by cutting the cable with side cutting pliers. Discard
the old mouthpiece tie.
4.2 DISASSEMBLY OF THE SECOND STAGE
! WARNING !
NEVER tighten the hose fitting to the first stage with more than 40 in. lbs.
(4.5 Nm) of torque. The inlet hose fitting can be weakened by over tightening.
To view the complete parts list of the second stage, open the front cover of
this manual.
4.2.1
Use the 6” and 8” adjustable wrenches to loosen the hose nut from the
adjust tube (18). Remove the hose assembly from the second stage.
Inspect the hose assembly for any cuts or cracks, especially on the hose
at the metal ferrules. If find Remove and discard the O-rings from each
end of the hose. Clean, rinse, and blow-dry the interior bores of the hoses.
Replace the hose assembly if any cuts or cracks are found.
4.2.2
If the mouthpiece is in good condition, you can don’t remove and be
reused. If not good to remove the mouthpiece (1) by cutting the
mouthpiece tie (2) with side cutting pliers. Discard the old mouthpiece
tie. Examine the condition of the mouthpiece.
4.2.3
Put the exhaust cover (5) into the hot water for a moment. Remove the
exhaust cover (5) from the housing by pulling it back.
Put the exhaust cover (5) into hot water for a moment. Remove the exhaust cover (5) from
the housing by pulling it back.
Before removing the exhaust valve (4) from the housing (3), bend the valve over as far as it
will go from the top, bottom, left, and right sides. If it fails to snap back quickly, and does not
lie perfectly at against the housing exhaust grid, the valve should be replaced. If it does snap
back satisfactorily, remove it by pulling it out with your ngers. Inspect the sealing edges. If
they appear smooth, and the locking tab on the nipple is good, the valve can be reused.
Unscrew the cover ring (8) from the housing (3).
If the cover is dicult to remove you can try several methods to loosen it;
1. Heat the 2nd stage body surrounding the Ring by running hot water from a tap over it.
When the plastic is hot, it will expand and loosen the threads.
2. Use an adjustable pin spanner.
3. Rubber pads are available to use in the hand to loosen tight jar lids.These pads will
allow you to get a better grip on the Cover Ring (8)
Remove the DIAPHRAGM WASHER (7) and the diaphragm (6) from the housing (3).
For future reference, look at the lever (20) at this time. Notice how the pivot end of the lever
is held into the inlet tube (18) by two plastic anges on the housing. Note this positioning for
re-assembly.
Hold the diaphragm up to a light source. Gently stretch the diaphragm and look for tears or
pinholes. If any are found, replace the diaphragm.
Loosen and remove the nut (26) from the inlet tube (18)
Remove the plastic bushing (25) from the inlet tube.
Remove and discard the O-ring (17) from the inlet tube.
Turn the ADJUST KNOB (10) fully counterclockwise until it comes to its stop. Do not use an
unreasonable force to do this. Stop turning the plug as soon as a resistance is felt.
Depress the lever (20) fully onto the inlet tube. Grasp the tab of the Venturi Lever (23). While
pulling on the Venturi Lever (23), push the inlet tube assembly out of the housing (3).
Remove the Venturi Lever (23) from the valve tube assembly. Remove and discard the O-ring
(24) from the Venturi Lever (23).
Turn the ADJUST KNOB (10) clockwise 1/4” turn. The pin (19) will fall out of the inlet tube or
can now be easily removed.
Turn the ADJUST KNOB (10) counterclockwise to remove it from the inlet tube. Remove and
discard the O-ring (11).
The balancing chamber (12), spring (13) and poppet (15) are removed at this time. They will
often fall out if the adjust tube is tipped on its end.
Remove and discard the O-ring (17) from the outside of the inlet tube (18).
The lever (20) should not be removed from the inlet tube unnecessarily. However, it can be
removed by carefully springing out one of the feet and pivoting it over the inlet tube. Do not
over-bend the lever legs. Straighten the legs if they are bent outward from parallel.
Remove and discard the LP seat (16) from the poppet (15).
Remove and discard the very small O-rings (14) from the poppet. This can be done by pinching
a section of the O-ring out of the groove with the ngernails. Then ip the O-ring o the end
of the poppet stem. DO NOT USE SHARP METAL PICKS! Metal tools will damage the O-rings
groove, which will cause a small continuous second stage leak.
Use an adjust tool to turn the orice (22) counterclockwise enough turns to fully disengage
the threads from the inlet tube (18).
After the threads are disengaged, remove the orice (22) from the inlet tube (18) by pulling
and turning counterclockwise at the same time or inserting a soft blunt ended instrument
from the other end.
Remove and discard the O-ring (21) from the orice.
