8 CALYPSO BC USER'S MANUAL

3.2 Connecting the MP Hose to the First Stage

1. Disconnect the inflator hose from the quick disconnect (QD) fitting and
set the hose to the side.
2. Use an appropriate size wrench or hex key, remove the port plug from a
medium pressure port that is located to the left of the port used for the
primary second stage.
3. Inspect the threaded male fitting of the inflator hose to ensure there is an
o-ring present. Make sure the o-ring is free of any visible signs of debris,
damage or decay.
4. Screw the male threaded end of the hose into the medium pressure port
to the left of the primary second stage. Tighten the hose with a 9/16"
crowfoot and torque wrench (recommended torque 40 inch-pounds).

4. INFLATION METHODS

4.1 Oral Inflation

To orally inflate your BC (See Fig. 2),
place your lips on the oral inflator mouth-
piece (A) and exhale a small amount of
air into the mouthpiece. This will purge
any water that may be still in the hous-
ing. While continuing to exhale into the
mouthpiece, depress the oral inflator
button (B) to inflate the BC. Immediately
after exhaling, release the oral inflator
button to prevent air from escaping.

4.2 Power Inflation

For the power inflator to work, the medium pressure inflator hose must be
connected. To connect the MP inflator hose, grip the grooved sleeve (C) with
your thumb and forefinger and slide the sleeve back. Place the hose fitting
over the quick disconnect (QD) fitting (D), and push inward while releasing
the sleeve. Check to ensure the hose is securely attached.
To inflate your BC with medium pressure air, depress the power inflate button
(E). Do not hold the inflator button depressed continuously underwater, as
this could cause you to become excessively buoyant. Instead, depress the
button in short bursts until you become neutrally buoyant.
