Questions and Answers for Zeagle CW Octo:

There are no questions yet.

The economical CW octopus is the same internally as the ZX 2nd stage, but is more compact and lighter because it does not have the adjustment knob. The CW Octopus has a Venturi Control Lever that allows the diver to set the octopus 2nd stage in the Pre-Dive position until needed. This is very important in Octopus regulators, since the Pre-Dive position is much more resistant to Venturi-Free-flows that can sometimes result in significant air-loss during a dive. The addition of the chrome plated brass heat sink makes the CW Octopus an simple, light weight choice for cold water diving. The CW Octopus comes with a Yellow cover and 36' hose.

PRE-DIVE CHECK (entire regulator)
1. Before mounting any Scuba regulator onto a tank valve, you must
open the valve briefly to blow out any water trapped in the outlet area
of the valve. Failing to perform this simple step will often result in water
and contaminants being blown into the interior of the regulator, which in
turn will cause future mechanical problems in the regulator.
2. Prior to each dive always check to make certain your regulator has
no potential water leaks by inhaling lightly on the regulator with the dust
cap properly installed, or the tank air valve turned off. You should be
able to draw in very little if any air. If you can draw in any quantity of
air, either the exhaust valve is failing to seal properly, or there may be a
pinhole leak in the mouthpiece or second stage diaphragm.
3. Mount the 1st stage regulator on the tank valve with the clear diaphragm end (with the black logo showing underneath) facing down.
4. Just before turning on the tank air valve, check to make sure that
the yoke nut or DIN connection is tight and that the regulator body is
aligned properly, with no kinks in the hoses. In the case of DIN connections, check that the DIN connector O-ring on the regulator is in place
before installing the regulator into the valve. Always carry spare DIN
connection O-rings (Zeagle p/n 160-0111-N7).
5. Turn the tank valve on VERY slowly. Check for air leaks and proper
breathing function of the regulator.


1. After the dive, dry the dust cap and place it securely on the 1st
stage regulator inlet. On multiple tank dives, keep water out of the
regulator inlet when changing the tanks. Neglect of these simple procedures is a major cause of corrosion and wear in scuba regulators.
2. With the dust cap securely in place, rinse the first and second
stage in clean fresh water. DO NOT purge the regulator before or
during rinsing since this may introduce water into the second stage
and the low-pressure hose. After rinsing, reconnect the regulator to
an air supply and thoroughly shake all excess water from the second
stage. Press the Purge cover (with the regulator attached to a pressure source) several times to blow the rinse water out of the inner
mechanism. Allow the entire regulator to air dry before storing. For
reasons of hygiene, equipment subjected to frequent use in training,
rental, etc. should finally rinsed in water containing a suitable sterilizing agent. The best sterilizing solutions for your regulator are soap
based. If any stronger chemicals are used, make the immersion very
brief and rinse the regulator out again thoroughly. Failure to rinse
sterilizing chemicals out of the regulator will cause serious damage to
plastic parts of the regulator. This will result in cracking of hard plastic
parts and shrinking or swelling of soft plastic parts.
3. Store the clean dry regulator in a clean bag or storage box, away
from sunlight, excessive heat and humidity

The ZX has a Resistance Control Knob. The Valve Seal in the
second stage will give longer service if the Resistance Control Knob
on the ZX second stage is turned fully counter clockwise when the
regulator is stored longer than a week.
