Z1 Warnings and Cautions
WARNINGS:
• Read the entire User Guide before using your Z1. Consult your health care provider if
there is any part of this User Guide you do not understand.
• US Federal law restricts this device to sale by or on the order of a physician.
• Use your Z1 and its accessories only for their intended use as described in this User
Guide and as directed by your physician, clinician or health care provider.
• The Z1 is not approved for use with oxygen. Do not use supplemental oxygen or
any other type of supplementary gas with your Z1. Do not connect supplementary
oxygen or other gas to any accessory or patient interface which is connected to your
Z1.
• If you notice any unexplained changes in the performance of your Z1 or your Z1
is making unusual or harsh sounds, or if the Z1 or Power Supply are dropped or
mishandled, discontinue use and contact the Human Design Medical Service Center
at 1-855-436-8729 [1-855-HDMUSA9].
• If your Z1, Power Supply, PowerShell or Battery is dropped or mishandled, or if water is
spilled into an enclosure, or if an enclosure is broken, discontinue use and contact the
Human Design Medical Service Center at 1-855-436-8729 [1-855-HDMUSA9].
• A mask is not provided. Your Z1 should only be used with masks and connectors
recommended by your physician, clinician, respiratory therapist or health care
provider.
• Your Z1 is intended to be used with CPAP masks (or connectors) which have vent
holes to allow continuous flow of air out of the mask. When your Z1 is turned on
and functioning properly, new air from the Z1 flushes the exhaled air out through
the mask vent holes. However, when the Z1 is not operating properly (e.g., at low
pressure) or the Z1 is off, insufficient fresh air may be provided through the mask and
the exhaled air may be rebreathed. Rebreathing exhaled air for longer than several
minutes can, in some circumstances, lead to suffocation. This applies to most CPAP
devices. Your health care provider will recommend a mask and air tubing to suit
your needs. The Z1 supports several CPAP mask types including nasal masks, full face
masks, and nasal prongs that meet the ISO 17510-2 standard.
• Do not use your Z1 with a mask unless the Z1 is turned on. Once the mask is fitted,
confirm that air is flowing from your Z1.
• Do not block the vent hole or holes in the mask. Follow the mask manufacturer’s
instructions for proper use of the mask.
• In the event of a power failure or machine malfunction, remove the mask
immediately.
• At low pressures some exhaled gases may remain in the mask.
• Electrocution Hazard – Your Z1 is an electrical device, and as such, you should not
immerse your Z1, Power Supply, PowerShell or Battery in water. Always unplug your

5
Z1 and its accessories before cleaning (and clean only as instructed in this User Guide)
and make sure your Z1 and its accessories are dry before plugging back in.

Charging the Battery (PowerShell Only)
WARNING: Only charge the Battery
with the supplied Human Design Medical
PowerShell and the supplied Human Design
Medical Power Supply. Do not use any other
battery charger, AC adapter, or other device
to charge the Battery.
With both the Z1 and the Battery fully inserted into the
PowerShell, plug the Power Supply into the PowerShell as shown
and into a power outlet. (Figure 13)
CAUTION: Make sure your Battery is fully
charged before commencing CPAP therapy
using the PowerShell. The battery life of
a fully charged battery in the PowerShell
is typically 8 hours or longer, after which
treatment will terminate. To recharge the
Battery, see “Charging the Battery”.
Ensure the Z1 is in standby mode (display reads 0.0). The Battery
will not charge unless the Z1 is in standby mode. The Battery
status indicator on the Z1 will flash when the Battery is charging.
The number of solid bars indicates the current level of charge.

As Needed
1. Clean the exterior of the Z1 with a soft damp cloth and mild detergent and wipe
clean. Never submerge the Z1 in water. Do not allow soap or water to enter the Z1.
Filter Replacement
The Filter should be inspected weekly for holes and blockage by dirt and dust, and should be
replaced every month (or more often if necessary). The Filter is accessed by removing the End Cap
as described in “Assembling and Powering Up: Filter and End Cap”.
NOTE: The Z1 uses a specially designed Filter that is only available from
Human Design Medical at 1-855-436-8724 [1-855-HDMUSA4] or online at
www.hdmusa.com.
WARNING: Do not attempt to use any air filter which is not supplied
by Human Design Medical for the Z1. The Z1 is designed to only work with
approved materials. A filter which is not approved may cause damage to
the Z1 from overheating.
CAUTION: Do not operate the Z1 without the Filter. The Z1 must
operate with a filter installed; failure to do so may damage the Z1 and allow
impurities into the respiratory system.
CPAP Tube Replacement
The CPAP Tube should be replaced according to the instructions provided with the CPAP Tube.
Reminder Alert (Air Leak Detection)
“REMINDER” is displayed on the LCD screen to indicate an excessive air leak. This could be because
you are not wearing your mask. Placing the mask on your face should remove REMINDER from the
display. If you are wearing the mask and REMINDER is displayed check the following connections
for air leaks:
• Tube Adapter to Z1
• CPAP Tube to Tube Adapter
• CPAP Tube to mask
• Mask to face (adjust position of mask and headgear to eliminate the air leak)
