2. Release the attachment webbing straps on the back of the LP by pulling
up on each strap just below the bottom edge of the pull-the-dot snap.
3. Feed the attachment webbing straps on the back of the LP through the
PALS webbing.
4. Reattach the pull-the-dot snaps by pushing down on the top edge of
the snap opposite the dot.
INFLATING THE LP
WARNING: When using the MD1250 LP in temperatures below freezing,
fully discharging the CO
2
cylinder may not provide adequate inflation. To
compensate, use the oral inflator tube to top-up the LP.
NOTE: After inflating both MD1250 LPs, secure them to each other with
the Velcro® attachment straps on the forward edge of each inflation cell.
Manual Inflation
To manually activate the hydrostatic inflator, jerk firmly downward on the
beaded manual inflation handle. The LP should inflate within five seconds.
Auto-Inflation
CAUTION: If the MD1250 LP has been orally inflated, CO
2
inflation could
over-pressurize and damage it.
When the uninflated LP is submerged in water, the hydrostatic inflator
releases CO
2
into the inflation cell, inflating the LP.
Special Considerations
Auto-inflation of the LP may create a risk of damage under the following
circumstances:
• Double inflation—CO
2
cylinder inflation after full oral inflation.
• Inflation while stored in a tight space.
• Inflation while in an awkward place or position.
Oral Inflation
Although a properly armed LP will correctly inflate manually or
automatically, the inflation CO
2
escapes slowly through the fabric and
a slight reduction in pressure is apparent several hours after inflation.
Therefore, oral top-up inflation may be required during prolonged
immersion (or in a non-emergency situation). To orally inflate the LP:
1. If necessary, open the zippers completely, and unfold the inflation cell.
2. Locate the oral inflation tube, and turn the locking ring clockwise to
open the inflator valve and unlock the mouthpiece.
3. Press (and hold) the mouthpiece down, and blow into the tube until the
LP is fully inflated.
