UML Pro-Sensor Installation and operation manual

1
Ensure all crewmembers are fully aware how the Lifejacket operates and also how to
manually activate the Lifejacket.
Check the single indicator status is fully green.
Check the correct CO2 Cylinder type and size is fitted.
Check the CO2 Cylinder is secured handtight.
Check the manual firing pull tab is accessible.
Check the lever is retained in place.
Check the automatic firing cartridge is within the expiry date printed on it.
Ensure the jacket fits correctly and is suitable for the conditions and individual wearing it.
Safety Information
The UML Pro-Sensor Automatic and Manual Lifejacket Inflators
UML RECOMMENDS THAT LIFEJACKETS ARE
WORN BY ALL CREW MEMBERS AT ALL TIMES
ABOARD THE VESSEL
BEFORE EACH USE:
When wearing inherently buoyant or foul weather clothing
the automatic firing cartridge may not activate as the unit
may not get wet.
IN SUCH CASES, MANUAL INFLATION WILL BE
ACHIEVED BY PULLING FIRMLY
ON THE PULL TAB.

• Affords the user a 'clearly visible' point of status
indication, to confirm that the unit has been
automatically or manually activated.
• The unit also provides the added benefit of
detecting if the CO cylinder has been pierced,
eradicating the possibility of accidentally
fitting a pierced gas cylinder.
• Simple re-charging procedure.
• The Automatic Pro-Sensor is fitted with the latest 'all weather'
Cartridge with the added benefit of inhibiting the accidental ingress of
moisture and water spray, during hot humid or heavy stormy weather.
• No service requirements for 3 years on the inflators.
There are two models of the Pro-Sensor Lifejacket Inflators.
A Manual version and an Automatic version which incorporates a manual activation.

The UML Automatic system activates when the Cartridge Mechanism comes into contact with water.
• The cartridge mechanism is a compressed high powered spring which is held by a
paper element.
• When the paper element comes into contact with water it releases the spring which
pushes a plunger forward
• The plunger forces the cutter into the CO cylinder. Allowing the CO to travel through
the CO gas hole in the inflator head and inflate the lifejacket.
• Total buoyancy is normally reached in 4-5 seconds.

When wearing inherently buoyant or foul weather clothing the
automatic cartridge may not be automatically activated as the
unit may not get wet.
• In such cases the manual back-up (pull tab) should be used
to inflate the jacket.
• All crewmembers should wear a lifejacket. Ensure the lifejacket
fits correctly and is suitable for the person wearing it.
• The Automatic system is backed up by a manual override, which
allows the user to pull the tab and inflate the lifejacket.
How the Automatic version works cont.
• When the system has fired automatically the
indicator system turns to red, sensing the
cartridge has activated and the CO cylinder
has been pierced.
The indication system will only show green when the product is correctly charged.

MANUAL FIRING PULL TAB
The UML Manual system activates when the pull tab is pulled.
• The pull tab is connected to a lever which pushes a plunger forward, in
turn forcing a cutter into the CO cylinder.
• The cutter allows the CO to travel through the CO gas hole in the inflator
head and inflate the lifejacket.
• When the system has fired the indication system
turns to red, sensing the CO cylinder has been
pierced.
• The indication system will only show green when
the product is correctly charged.
• Total buoyancy is normally reached in 4-5 seconds.

Testing Your Lifejacket with the UML Pro-Sensor Automatic Inflator.
• If you want to test your life jacket in the water. Open the lifejacket
following the manufacturers instructions
• Remove the automatic cartridge and CO cylinder from the Inflator.
• Inflate the jacket through the oral inflation tube
• Don the lifejacket, following the manufacturers instructions
• Go swimming. (Warning: If you are not a competent swimmer ensure the
test is performed in safe shallow water, with help at hand).
• Familiarise yourself with the way the you float when wearing the lifejacket
• After you swim let the jacket dry off completely, then deflate it.
(Instructions for this procedure will be in the lifejacket owners manual).
• Replace the automatic cartridge and CO cylinder ensuring the indication
returns to green (See rearming your Pro-Sensor Automatic Inflator).

Rearming your UML Pro-Sensor Automatic Inflator
• Take the new automatic cartridge and screw onto
the inflator head in a clockwise direction. Screw right up
ensuring there is no gap between the cartridge and
inflator head and then do up hand tight.
BLACK WASHER
• Ensure once the operating head is rearmed that the
indication system is showing completely green in the
indication window.
• If fired manually replace the firing arm into the unit.
The arm will click into place, thereby preventing the arm
from moving.
• Check that the cylinder sealing gasket in the end of
the operating head has been correctly fitted, or replaced
if necessary. Check the new CO Cylinder has not been
used and screw into the inflator body in a clockwise
direction. Ensure the cylinder is screwed right down and
do up hand tight.
