Specification
Standard Pull Cord Length 160mm.
Part Number: UMA4012/C160 (This part replaces UMA4012/B160).
Description: MK5 Auto Inflator Assembly Yellow - 1/2'' with 160mm long nylon pull cord.
The UML MK5 Automatic system activates when the cartridge comes into contact with water. The cartridge mechanism contains a compressed high powered spring which is held by a cellulose paper element. When the paper element comes into contact with water it dissolves and releases the spring which pushes a cutter forward to pierce the CO2 cylinder and release the CO2 gas. The gas then travels through the one way valve in the inflator head and inflates the lifejacket.
The Automatic system is backed up by a manual override, which allows the user to pull the toggle and activate the cutter to pierce the gas cylinder in order to inflate the lifejacket alternatively.
How the Indication System Works
The indication on the standard MK5 Automatic inflator allows the user to establish if the system has been fired. The standard MK5 Automatic inflator does not indicate if a pierced CO
2 cylinder is accidentally refitted to the inflator during the servicing procedure. The CO
2 cylinder must be checked each time you don your lifejacket to ensure it is not pierced and it is tightly screwed in by hand. In addition the cartridge must be checked to ensure it has not passed the replace by date, it is also fully screwed on tightly by hand and water is not restricted from entering the system.
There are 2 forms of indication :
- The Automatic Indicator
- The Manual Indicator
Both indications must be green, the Automatic Cartridge must be fully fully screwed on hand tight and must be within the printed Replace By Date and a fully screwed in hand tight, full CO2 Cylinder for correct operation.
The Automatic Indicator is positioned on the base of the Automatic Firing Mechanism.
GREEN indicates
OK, and
RED indicates
STOP/
NOT USABLE.
The Manual Indicator is positioned on the side of the firing head.
GREEN indicates
OK, and
RED indicates
STOP/
NOT USABLE.
These should checked each time the lifejacket is worn.
If either or both of these indicators are red or missing please refer to the Re-arming tab above.
