pre-Issue Checklist

Before each use, the unit must be given a thorough visual inspection and
functional test by a qualified technician. NEVER use an SEA which shows
signs of damage, leakage, or substandard performance until it has received
inspection and service from a qualified technician.

SEA MK and LV2, regardless of which second stage is used.

nected into its respective port on the first stage and onto the second
stage. Inspect the length of the hose to ensure that it is not blistered,
cut, or otherwise damaged. Inspect the hose fittings for any signs of
corrosion.
2. Visually inspect the entire system for any external damage, such as
dents, gouges, or severe external corrosion.
3. While the SEA valve is completely shut and the system is
depressurized, inspect the pressure indicator assembly to ensure that
it is securely fastened to the first stage. Closely examine the pressure
indicator to ensure that it reads zero.

do Not attempt to use the system until it has received
inspection and service from a qualified technician.
