1. IMPORTANT
This manual contains preliminary servicing instructions for the Poseidon breathing regulators. It is intended to
serve as a guide for repairs and servicing carried out by Poseidon Diving Systems. The instructions given in this
manual are based on the assumption that special tools are used and are based on our experience.The work
should be done in the same order as shown in these instructions.
TYPE DESIGNATIONS
In all correspondence concerning breathing regulators, indicate the type designation and serial number. All
products in this servicemanual that requires a CE-approval are of course CE-approved. CE approval represents
only a minimum level of product quality and manufacturing standards. At Poseidon we put each new addition
through rigorious testing procedures our selves. This is the only proper method to ensure that your equipment will
live up to our claims.
CLEANING
If corrosion or salt deposits occurs, place all metal parts in concentrated Hempocid* or 15% Hydrochloric acid for
about 10 minutes. If available, all metal parts can be placed in an ultrasonic washer and cleaned in accordance
with the instructions of the cleaning solution used.
Then, rince the parts thoroughly and blow dry with air. The synthetic parts in the second stage must not be treated
with solvent. They shall be cleaned in freshwater only.
*Hempocid = Acid Liquid Detergent Containing phosphoric acid (5 - 10%) and bactericid for desinfectant cleaning.
LUBRICANTS USED
The following lubricant is used:
Regulator Lubricant: Art No: 8516
FUNCTION
POSEIDON breathing regulator is a two-stage regulator where the rst stage is a diaphragm-actuated
reducing valve, whith reduces the primary pressure (Cylinder pressure) to approx. 123 PSI/8.5 BAR. The reduced
pressure (the secondar’y pressure) then goes via the regulator hose to the second stage where the air
supply is automatically regulated to the convenience of the diver.
The rst-stage always holds the adjusted pressure above the ambient pressure which is necessary to the
function of the breathing regulator. This is brought about by the outer springloaded diaphragm being in
contact with the ambient pressure. It automatically responds to this pressure acting it and thereby
regulates all changes in pressure.
The second-stage functions in such a way that the underpressure created in the regulator housing
during each inhalation inuences a servo valve system, which will supply the necessary
air as long as the inhalation phase lasts. The automatic pressure compensation takes place in the same
way as in the rst stage, the outer diaphragm surface being in direct contact with ambient pressure, and
the pressure on the inside of the diaphragm must correspond to ambient pressure before the diaphragm
can return to its position. The diaphragm retums to its rest position and shuts off the air owing in as
soon as the inhalation phase has been broken off and the air pressure in the regulator housing has
become equal to ambient pressure.
The second stage has a built in purge button, for manual purging.
