External Components Description
Air Pressure Gauge
This gauge indicates the air pressure being delivered by the internal air
compressor to the sieve beds. It should vary between
30-45 psi (2.1-3.1 bar)
while the unit is operating.
ON/OFF Power Switch
This switch controls power to the machine. It is lighted when the machine
switch is in the
ON
position.
Hours Meter
The hours meter shows how long the unit has been operating. This helps
indicate when service intervals are due.
Oxygen Pressure Gauge
This gauge indicates the pressure at which the oxygen is being delivered.
The flow meter is calibrated at
12 psi (0.83 bar)
for
OG-15
and
20 psi (1.4
bar)
for
OG-20
and the pressure must be adjusted to this level when reading
the flow meter. The oxygen regulator can adjust the pressure.
Oxygen Pressure Regulator
The regulator controls the oxygen delivery pressure level. To adjust the
oxygen delivery pressure level, pull the adjustment knob easily towards
you. Turning it clockwise increases the delivery pressure while turning it
counter-clockwise decreases the delivery pressure. The oxygen pressure
gauge will indicate the level set. To lock it into place, push down the
adjustment knob.
Vent Holes
These vent holes allow cooling air to enter and exit the enclosure.
Reset Button
The reset button is actually a circuit breaker that opens if there is an electrical
overload in the system and/or if there is any back pressure within the air
and/or oxygen lines.
Oxygen (O
2
) Outlet
This fitting is a ‘B’ size oxygen adapter. It can be removed to expose a
1
/
8
”
female NPT pipe fitting.
