SINTHESIS
CRUISER OCTOPUS
WARNING:
On the surface to avoid any free flow resulting from surface waves
and / or sudden entry in the water, the diver should keep the lever
pushed towards the front in the (-) minus position. This position
should be maintained whenever the second stage is used as an
octopus for a safe second stage.
At the beginning of the dive, the diver should push the Venturi
lever in the + / plus position, to obtain optimum breathing
characteristics. The + / plus position is the ”dive mode” position.
Inhalation resistance
This knob, located on the left hand side of the Polaris hosing, allows to
adjust the resistance on the Polaris spring and thereby to alter the initial
breathing resistance. The diver can choose any position between the
minimum (turned completely counter clock wise) and the maximum
(turned completely clock wise) depending on the conditions. Turning the
knob clockwise will increase the inhalation resistance, turning it counter
clockwise will decrease the inhalation resistance. When the inhalation
resistance knob is in the minimum position, there may be a light free flow
If this is the case, slightly turn the knob clockwise until the air flow stops. Or
have your regulator checked by an authorized COLTRI SUB dealer.
IMPORTANT:
- The Polaris first stage 3/8” LP ports can accommodate the safe
second stage octopus and the buoyancy compensator LP hose
and / or drysuit inflator hose.
- On the 7/16” HP port, install a pressure gauge to check air supply
during the dive.
- A 3300 psi DIN or 4400 psi DIN connection kit can be installed on
the Polaris first stage by a COLTRI SUB authorized dealer
- A 3300 psi DIN to yoke adapter is available under to allow the
mounting and the use of a DIN regulator on a standard K-valve
cylinder.
