TECHNICAL BULLETIN
SUBJECT: Titan / Calypso Opening Effort Improvement
PRODUCTS AFFECTED: The regulators in question are the
2010 models of Titan, Calypso and Octopus, references:
128500, 128700, 128560, 128540 and 128550
We have been informed that certain Titan and Calypso second stages (2010 models)
require an inhalation effort slightly greater than normal. Tests have shown this inhala-
tion effort is due to the quality of the crown 128621 sealing surface. In a constant goal to
improve the quality of our products, we have modified the crown material and improved
the sealing surface area. This new material is easily recognizable by its blue color, as op-
posed to the current gray crown.
CURRENT
CROWN
This modification provides a better seal with the seat, allowing the technician to set the
crown at its ideal position for optimal inhalation effort.
Corrective Action
This problem only concerns a few of the Titan, Calypso and Octopus regulators included in a batch
whose the serial number begins by the letter "A" and with a serial number lower than 100801.
We recommend systematically replacing the crown during the annual servicing/inspec-
tion of these regulators and also for every regulator from customer returns which would
have a high inhalation effort.
To facilitate this operation, we have created a kit reference 128698 which includes a new
blue crown with o-ring and a MP seat. Please call our Customer Service Department at
877-253-3483 to request kits. Please be patient with us as we will limit the number of kits
until our supply gets caught up.
Use the procedure below to install the new crown, this was taken from the technical
manual of the Titan/ Calypso second stage:
