NOTE
It is not necessary to remove the warning light electrical wire or the face piece vent tube from the
breathing tube
h. Disconnect face piece (12) from breathing tube (10) and lay face piece (12) to the side.
NOTE
The breathing tube should be kept as straight as possible to ensure the most accurate gauge readings
i. Connect breathing tube (10) directly to inlet connection (6).
WARNING
High pressure air hazard. Always attach the regulator to its appropriate air supply source. Never attach a
low pressure air line regulator to a high pressure air supply without an in line regulator to step the pressure
down Failure to follow this warning could result in severe personnel injury or death due to over-
pressurization and explosion
NOTE
The air line supply pressure to the EBA should be 85-90 PSIG.
j.
Attach remote air supply line (13) to tether line connection (14).
k.
Ensure flow valve (4) is closed by turning it clockwise.
I.
Ensure regulator valve (15) is closed
m.
Turn on the remote air supply.
n.
Turn the regulator tester on by depressing on/off switch (7).
o.
Completely open regulator valve (15).
p.
Slowly open flow valve (4) until flow gauge (1) reading matches the hand-written value for an air,
flow of 200 liters/minute on flow calibration chart (8) located on the inside front cover of the
regulator tester.
q.
The corresponding pressure gauge (2) reading should be between 0 and +2.4 inches of water.
r.
If pressure gauge (2) reading is not between 0 and +2.4 inches of water, perform the following
checks:
3-73
