AS-20—1000 Instruction Manual
If the pressure gauges do not decrease to zero, shut down the
unit and call the AirSep Corporation Commercial Products
Division.
8)
If the unit is depressurized, power down the unit if required and proceed to
perform the maintenance.
7.7
Adjusting the Feed Air Regulator
If the feed air regulator requires adjustment, perform the following procedure. If
applicable, remove the front cover of the enclosure to gain access to the regulator.
(See Section 7.3, Removing the Front Cover of the Enclosure.)
Use extreme caution when performing this procedure since it
requires removal of the front cover of the enclosure while the
unit receives electrical power.
1)
Unlock the lock nut on the adjustment knob.
2)
To increase feed air pressure, rotate the knob clockwise. To decrease feed
air pressure, rotate the knob counterclockwise.
Make slight adjustments and allow the unit to run through at
least one cycle before making another adjustment. If pressure
readings remain incorrect after the cycle completes, continue
making slight adjustments and cycling the unit until the
pressure is within the manufacturer’s specifications.
7.8
Adjusting the Pressure Switch
Although preset at the AirSep Corporation factory to the pressure switch minimum
and maximum pressures specified in Appendix A of this instruction manual, the
pressure switch may require adjustment if the pressure of the oxygen in the
oxygen receiver registers outside the range specified in Appendix A. Follow the
procedures in this section to adjust the pressure switch settings when required.
