FUNCTION<br />
20 Inlet From Blender DISS oxygen fitting for connection to an inline Inlet Filter Cartridge and then to the External<br />
Air/O2 Blender output. The nominal pressure of the blender output gas should be 50 psig. The<br />
Source Gas Low yellow LED will light if the pressure at the inlet drops below 30 psig ±5%.<br />
This input connection is protected from over-pressure by a 75 psig mechanical relief valve.<br />
More details regarding this protection are listed in Chapter 3, Specifications.<br />
21 Outlet to Humidifier Connector which provides bias flow to the inlet of the External Humidifier. This is a 3/8" barbed<br />
fitting which is over-pressure protected by a 5 psig mechanical relief valve. The Patient Circuit<br />
assembly procedures associated with this connector are discussed in Chapter 6, Assembly<br />
and Installation.<br />

24. Elapsed Time Meter Indicates the total accumulated time in hours that power has been applied to the Model <strong>3100B</strong>.<br />
Detailed specifications of this meter are discussed in Chapter 3.<br />
25 Power Failure Alarm<br />
Battery and Battery<br />
A metal cover (fastened by 2 screws) behind which is a 9-volt alkaline battery. Battery Low<br />
LED (15) on front panel indicates when this battery needs to be changed. It can be replaced by<br />
Compartment<br />
any high quality 9-volt alkaline battery. Note: remove the 9-volt battery if the instrument is not<br />
intended to be used for a lengthy period.<br />
26. Position Lock Locks the Control Package in the rotational position selected by the user. When this lock is<br />
rotated counterclockwise, it allows the rotation of the Control Package over an arc of nearly<br />
360°. This permits viewing of the Model <strong>3100B</strong> front panel from an angle independent of the<br />
Patient Circuit outlet orientation.<br />
After the desired position has been selected, rotation of the knob in a clockwise direction will<br />
lock the enclosure in the selected position.<br />
Rotation of the knob slightly counterclockwise from fully locked will apply friction to prevent the<br />
enclosure from easily being rotated without actually fixing it in place.<br />
More on the subject of positioning of controls is discussed in Chapter 6, Assembly and<br />
Installation.<br />
27. Air Cooling Inlet An Air DISS fitting for connection through an in-line Inlet Filter Cartridge to hospital air supply<br />
which provides the oscillator with cooling gas. The nominal pressure of the hospital air should<br />
be 50 psig at the required 25 LPM rate. The Source Gas Low yellow LED will light if the<br />
pressure at the inlet drops below 30 psig ±5%.<br />
