Fresh Gas/Emergency Air Intake Filters; Inspecting And Replacing The Foam Filter; Inspecting And Replacing The Disk Filter - ZOLL Z Vent Operator's Manual

Fresh Gas/Emergency Air Intake Filters

The Fresh Gas/Emergency Air Intake (located on the right side of the ventilator) has a two
stage filtering system: an easily accessible foam filter protects a second disk filter. As we
describe in Chapter 6, "Operating Environments," additional filter protection may be necessary
when operating the device in extreme environments. These filters are replaced every year
during the preventative maintenance performed by a ZOLL authorized service center.

Inspecting and Replacing the Foam Filter

When used in dusty environments, you should inspect and replace, if necessary, the device's
foam filter.
Remove the filter using a pair of tweezers or similar tool. Examine the filter for dirt, lint, or
general wear. Replace the foam filter, if necessary. DO NOT attempt to clean the filter.
Caution Do not operate the compressor without a filter in place.

Inspecting and Replacing the Disk Filter

The Fresh Gas/Emergency Air Intake Disk Filter is located behind the Foam Filter. This filter
provides a second level of filtration to the ambient air that is delivered to the patient. You must
check this filter periodically and replace it if necessary. The ventilator triggers an alarm when
the combination of foam filter and disk filter become dirty. This alarm indicates that the device
is still able to deliver the correct tidal volume but one or more of its filters needs replacement.
You can visually inspect the Fresh Gas/Emergency Air Intake Disk Filter after the Foam Filter
is removed. If the filter appears discolored, replaced it.
Warning! If filters are exposed to biological matter, dispose of them following Universal
Precaution procedures for your facility.
Caution There are no user serviceable parts except the filter components above. Opening the case can
damage the ventilator.
Caution When used in dusty/dirty environments, you should check the foam and disk filters, and replace
them as needed. This prevents particle build up on the transducer screen and the need to take the
device out of service for maintenance by a service technician.
