CARE AND MAINTENANCE OF THE EQUIPMENT
ASSEMBLY PROCEDURE
The illustration on page 6 may be helpful.
1. Visually inspect all parts for damage prior to assembling the MT400DTK.
2. Attach a suitable airline fitting to the hand slide valve end and mount the air regulator/valve
in an upright position.
3. Fit one end of the blue air line into the push connector on the regulator, and the other end
over the barbed fitting located on the end of the air coupling.
4. Ensure that the hand slide valve is in the off position (blue slider pushed away from the
regulator).
5. Connect a compressed air supply to the air line.
6. Adjust the regulator knob by turning it anti-clockwise so that the pressure will be 0 psi at
first. This will avoid over pressurizing the EPIRB bottle during the test.
MAINTENANCE
The illustration on page 5 may be helpful.
• After use, dry the parts of the test kit.
• Regularly inspect the parts of the leak test kit for visible signs of deterioration.
• In particular, check the O ring on the end of the air coupling for wear and/or damage.
Replace it if necessary.
EPIRB TEST PROCEDURE
PREPARATION
You will need a water tank, preferably with transparent sides, large enough to contain the
EPIRB, in the cradle, with the air hose attached and not bent too sharply.
1. Fill the tank with fresh water sufficient to cover the EPIRB.
You may find it convenient, once you find a suitable water level, to make a water level mark
on the tank without an EPIRB.
2. Ensure that the water is free from contamination by visual inspection. Replace the water
when it is no longer clear.
PERFORMING A LEAK TEST
The illustration on page 5 may be helpful.
1. Ensure that you wear appropriate PPE. See Environment and PPE on page 3.
2. Pull back the air coupling against the spring and rotate it approximately 90° in either
direction to lock it into position.
You are now ready to insert the EPIRB unit under test (UUT).
3. Insert the EPIRB into the cradle as per normal operation.
4. Pull back the air coupling slightly and rotate it back to the original position to unlock it.
Then slowly allow the spring to push the coupling against the EPIRB, such that the tip gently
engages into the EPIRB test point.
5. Ensure the O ring is pressed up firmly against the EPIRB cap in order to create an airtight
seal.
6. Set the regulator pressure to 1.0 bar (100 kPa or approximately 15 psi) by adjusting the blue
control knob on the top of the regulator.
Note that too much pressure in the EPIRB could damage it and render it inoperable. Should
it explode, it can result in injury to persons and damage to other property.
