4.1.1 Adsorbers

The adsorbers, or beds, are vessels that contain the molecular sieve used to
adsorb (attract) nitrogen from compressed air and allow oxygen to pass through as
the product gas.

4.1.2 Enclosure

The enclosure protects the control system components of the unit (e.g., circuit
board, pressure switch, fuses, and transformer).
Power Cord
(U.S. units) The power cord, and its grounded plug, connects the oxygen
generator to a properly grounded electrical outlet to supply electrical power to
the oxygen generator.
(CE units) A fully qualified electrician must install the appropriate electrical
connection on the end of the power cord for a properly grounded electrical
outlet to supply electrical power to the oxygen generator.
Fuse Holder
The fuse holders contain fuses to protect the electrical components of the oxygen
generator. On the AS-450 through AS-1000 models, the fuse holders are mounted
in the control panel.

4.1.3 Control Panel

The control panel on the oxygen generator contains the controls needed to operate
the oxygen generator and monitor its operation. Examples of typical control panels
are shown in figure 4-3. Not all components are available on every generator. On
the AS-450 through AS-1000 models, the gauges are mounted directly on the
manifolds and the hour meter is inside the control panel.
4-2
Disconnect power before opening and/or removing enclosure.
Fuses must be replaced with the same type and amp rating as
the original fuses.
