GENERAL

If the Workhorse Oxygen Concentrator is supplied with a cover, make certain the
fan cord is connected to the fan on the cover, before reinstalling the cover. The
length of the cord provides for cover removal without disconnecting the cord from
the fan.
To start the Workhorse Oxygen Concentrator, connect the unit to a grounded power
source rated for the voltage and current requirements stated on the label on the
unit. Push the toggle switch on the front panel to the up position. [The green LED
on the front panel of the unit will light, indicating that power is applied to the system,
and the red LED will light indicating low oxygen concentration.]
Set the outlet oxygen flow to 4 LPM (8 SCFH) or less. [When the oxygen
concentration achieves 70%, the red LED will go out and a yellow LED will light.
When the concentration is greater than 85%, the yellow LED will go out.]
[The visual LED alarms also correspond to two alarm outputs on the nine pin D-sub
connector located under the LEDs. These outputs are Form A one amp dry contacts.
They are normally open and then close during an alarm. Only one contact is closed
at any time during an alarm. If the oxygen concentration falls below 85%, the yellow
LED will light and pins 4 and 5 will close. If the concentration falls below 70%, these
contacts will open and the yellow LED will turn off. The red LED will then light and
pins 2 and 3 will close.]
[Pins 1 and 6 can be used to measure the concentration level to within ±2% of
concentration. This is read by placing the negative lead of a digital voltmeter on pin
1 and the positive lead on pin 6. A 0-1 volt output is displayed with one volt relating
to 100% and zero volts relating to 0%. Audible and visual alarms, automatic phone
dialers and digital oxygen purity displays that directly interface with the nine pin
connector are available as accessories. Contact AirSep for additional information.]
[ ] Applies to models with optional oxygen monitor.
Please contact AirSep Technical Support if additional assistance is required.
Do not allow the oxygen product to vent freely. Do not exceed rated capacity.
Workhorse-8 Instruction Manual
The flow meter installed on the Workhorse Concentrator is set to
read accurately when the discharge is to atmospheric pressure. If
the actual discharge pressure is substantially above atmospheric
pressure, the reading can be adjusted to determine the precise
flow rate, according to the following formula:
(adjusted flow) = (measured flow) x √oxygen pressure + 14.7
