19SEA USER'S MANUAL

NOTE: Part Number 108382 and 108485 do not have an

on/off valve; therefore, the pressure indicator gauge and

second stage are always active when the cylinder is pressur-

ized.

CAUTION: If the pressure indicator does not read zero

when the valve is shut and the system is depressurized,

DO NOT attempt to use the system until it has received

inspection and service from a qualied technician.

CAUTION: DO NOT attempt to open the SEA valve without

rst checking to ensure that the LP hose and pressure

indicator assembly are securely fastened to the rst stage.

NOTE: Pre-Issue checkout procedures are identical for the

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

Pre-Issue Checklist

Before each use, the unit must be given a thorough visual inspection and

functional test by a qualied technician. NEVER use an SEA which shows

signs of damage, leakage, or substandard performance until it has received

inspection and service from a qualied technician.

1. Carefully inspect the low pressure hose to ensure it is securely con-

nected into its respective port on the rst 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 ttings 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 rst stage. Closely examine the pressure

indicator to ensure that it reads zero.

4. Turn the SEA valve handwheel counterclockwise until it is completely

open. In the open position, the red indicator ring is not visible in the

handwheel.
