Installation
The Tank Unit (TU) high-pressure sensor installs into a high-pressure port of your
first-stage regulator. This should be done by your Authorized Dealer at the time of
purchase. Should you choose to install the TU yourself:
1. Remove your current high-pressure hose or the high-pressure plug from your first
stage regulator.
2. Lightly lubricate the sensor o-ring only with a lubricant approved for use with
Enriched Air Nitrox equipment. DO NOT USE SILICONE GREASE.
3. Screw the sensor, HAND TIGHT, into the first-stage high-pressure port
4. Using a 9/16" open-end wrench, "snug" the high-pressure transducer connection
taking caution to not overtighten.
CAUTION: DO NOT use your hand to tighten the high-pressure connection. This
procedure should only be accomplished by using an open-end wrench placed over
the metal nut of the high-pressure connection. It must not be overtightened.
With the first stage properly attached to a filled SCUBA cylinder, slowly open the cylin-
der valve. Once the valve has been opened, listen to the TU’s high-pressure connec-
tion for any escaping gas. If possible, completely immerse the tank and regulator in
water to see if bubbles form around your connection. If any gas leak is seen or heard,
immediately turn the gas off by closing the cylinder valve and take the entire regulator
system to the place where your purchased your NEMESIS™ IIa NITROX.
The Tank Unit (TU) clips to a low-pressure hose close to the first-stage. When clip-
ping the TU onto the low-pressure hose, a rolling motion will provide better results
rather than pushing the TU straight down onto the hose. The Wrist Unit (WU) may be
worn on the wrist or attached to your Buoyancy Control Device.
Activation
The TU will automatically activate when it senses a cylinder pressure greater than 200
psi or it may also be manually activated by tapping on the TU case in the circle area
that says "PWR" for approximately three seconds. Should you choose this manual
method of activation, it must be understood that the tapping should be performed in a
manner that produces sound rather than vibration. When tapping, you should use
your fingernail, coin, or other hard object that will produce sound when tapped against
the TU case. In general, using your fingertip will not provide the necessary sound to
successfully complete manual activation. The TU will issue five beeps as it begins its
activation sequence.
NOTE: If the TU is in the Altitude Adaptation Mode, four beeps instead of five beeps
will be issued.
It is also required that the TU be no deeper than 3 feet of water in order to activate.
Should you be deeper than three feet and attempt to activate the TU by using either
cylinder pressure or manually via tapping, the TU will not turn on. You must ascend to
a depth less than three feet and re-initiate the activation sequence.
