MAINTENANCE
2. Check the audible alert and indicator lights during every service. When the
power switch is turned “On,” listen for the audible alert and check to see if
the front panel indicator lights are operating.
3. Inspect intake lter (part #MC44D-605) during every PM Check. Replace
as necessary.
a. Open the lter door and replace lter as required.
4. Inspect the nal bacteria lter (part #PV5LD-651) during every compressor
service. Replace as necessary.
a. Use the Cabinet Removal instructions found under CABINET
REMOVAL in this manual to remove and attach the cabinets.
b. Remove the hose from each end of the lter and discard the lter.
c. Install the new nal bacteria lter with the “IN” tting toward the ow
meter.
5. Inspect the compressor lter during every compressor service. Replace as
necessary.
NOTE–A change was made to the type of compressor lter used in the 525
series concentrator. The unit may have one of two different types of compressor
lters depending on when the concentrator was manufactured. The original one
is a white plastic lter (part #525D-622) that is located near the compressor. The
newer style is a sintered bronze lter (525DD-626) that is installed in one end of
the compressor exhaust hose near the rotary valve. All models of the 525 series
are now being manufactured with the sintered bronze compressor lter. See
gure below.

NOTE– This PM Schedule reects:
• 5000 hour usage equal to one year
• a normal, clean operating environment.
The homecare provider is responsible for:
• determining the condition of the concentrator operating environment.
• determining a preventative maintenance interval frequency* which
takes into consideration the specic operating environment.
* Standard intervals are noted below. Service interval may be more
or less frequent than stated below provided that the Home Care
Provider establishes and documents appropriate protocols.
WARRANTY
DeVilbiss provides warranty for this device. Use only DeVilbiss approved original
spare parts for maintenance and repair to retain warranty. Using unapproved or
non-original spare parts would void warranty.
PROVIDER’S NOTES - Cleaning and
Disinfection When There is a Patient
Change
When medical devices have already been used with a patient, contamination
with human pathogenic germs should be assumed (unless there is evidence to
the contrary), and the next patient, user or third party should be protected by
appropriate handling and preparation.
Therefore, when there is a patient change, people must be protected during the
transport and handling of the device, and the device must be fully processed,
i.e., cleaned and disinfected, by suitably trained personnel before reuse to
protect the next patient. The complete processing may only be done by the
manufacturer or by a qualied DeVilbiss provider/service technician.
NOTE–If the following described complete processing of the concentrator by a
qualied DeVilbiss provider/technician is not possible, the device must not be
used by another patient!
DeVilbiss Healthcare recommends that at least the following procedures be
carried out by the manufacturer or a qualied third party between uses by
different patients.
NOTE–If preventative maintenance is due at this time, these procedures should
be carried out in addition to the servicing procedures.
1. Dispose of all accessory components that are not suitable for reuse, i.e.,
particularly the oxygen tubing, the nasal cannula/mask, oxygen outlet
connector and humidier bottle.
2. CAUTION–the concentrator must be disconnected from the power
supply for this step: Open the concentrator and remove all dust deposits
inside the cabinet with an appropriate vacuum cleaner.
3. Clean and disinfect all parts of the cabinet inside and outside and the
power cord with a suitable disinfecting agent, e.g., Microbac Forte,
Terralin®, Aldahol, Cidex OPA or Peract.
4. Check the cord, the plug on the back of the device, the power switch, the
fuse holder and the indicator light for possible damage.
5. Replace all damaged or worn components.
6. Replace the cabinet air lter on the back of the device.
7. Check the oxygen concentration. If the device is within specications, the
intake bacteria lter does not need to be replaced between patients. If the
concentration is not within specications, the provider should refer to the
service manual section on Troubleshooting.
RETURN AND DISPOSAL
This device may not be disposed of with household waste. After use of the
device, please return the device to the dealer for disposal. This device contains
electrical and/or electronic components that must be recycled per EU Directive
2012/19/EU-Waste Electrical and Electronic Equipment (WEEE). Non-infectious
used accessories (e.g. nasal cannula) can be disposed of as residential waste.
The disposal of infectious accessories (e.g. nasal cannula from an infected user)
must be made via an approved waste disposal company. Names and addresses
can be obtained from the local municipality.
