Cressi AC2 - Disassembling and Maintenance

2.2 – Master 2
nd
stage, disassembling and maintenance
In designing the Master regulator, the ease and speed of disas-
sembling and maintenance were taken into account, indispensa-
ble features to have a regulator always perfectly serviced,
calibrated and efficient.
� WARNING: the opening, maintenance and calibration of
the 2nd stage should only be carried out by authorised
Cressi-sub centres and the calibration values CANNOT and
MUST NOT be changed by the user, to avoid prejudicing the
good working order of the regulator. We cannot be held in
any way liable for any intervention carried out by staff unau-
thorised by Cressi-sub.
The Cressi-Sub authorised centres can be indicated by retailers
or alternatively by Cressi Sub s.p.a. (email: info@cressi-sub.it).
Using the Allen key provided with the regulator to unscrew the
first stage HP and LP plugs, you can open and disassembly the
2nd stage case, directly accessing its internal mechanics. This ex-
traordinary feature, which is unique in the sector and patented,
makes opening the case very easy and extremely fast to clean
and check the various parts are working perfectly.
In fact, the cap and the central chamber of the exhaust are me-
chanically bound to one another thanks to the innovative “cam-
lock” (patented) closure system which enables the fastest
opening and closure of the “folding” case, temporarily locking the
cap and diaphragm with an extremely efficient and precise effect.
The opening and closure phases of a regulator have never been
so simple and, at the same time, so safe!
To facilitate and speed up the inspection, servicing and tuning op-
erations, all the second stage mechanics are entirely removable
in an instant from the case, without altering its calibration.
The disassembly and replacement operations for worn parts, dur-
ing periodical service maintenance, can be carried out with all the
mechanics of the regulator at hand, enabling extraordinarily easy
operations.
