    Small & Discreet for Travel

    The Z1 Auto machine is designed for use on the go or staying at home. It easily fits into a backpack for camping and hiking or into a carry on bag for travel. The unique design more closely resembles an electric razor than a CPAP machine. The small footprint of the machine takes up little room on the bedside table. The machine has small rubber feet on the base to help stabilize the unit. The Z1 Auto weighs in at 10 ounces and measures 6.48 inches long x 3.3 inches wide x 2.02 inches high.

    Nitelog App and Data Reporting

    The Z1 Auto has a built-in Bluetooth chip used to wirelessly connect to a nearby smartphone or tablet using the free Nitelog app. This machine transmits usage data to the phone or pad for review using the application. Nitelog will allow the user to adjust basic machine settings such as Z-Breathe and ramp. Nitelog compiles the reports for the past day, week or 30 days of use. The report can be emailed from the smartphone or tablet, or screen shots can be snapped and stored to the memory of the phone or pad. The Z1 functions can be performed on the Z1 machine without the use of Nitelog.

    • Using Nitelog: Download the Nitelog App from The App Store or Play Store to a smartphone or tablet (NOT included with purchase).
      • Turning Bluetooth ON:

        1. Unplug the power adapter from the machine.
        2. Plug the power adapter back into the Z1 and immediately hold the Up Arrow Button.
        3. When Bluetooth has been turned on, the display above the pressure indicator shows "bt-On".
        4. The Bluetooth function recognizes and syncs with the Nitelog App on the nearby phone or tablet.

      • Turning Bluetooth OFF:

        1. The Z1 machine can be set to NOT transmit data by using Airplane Mode.
        2. To turn off the Bluetooth, unplug the power supply from the back of the machine.
        3. Plug the power supply back on and immediately hold the Down Arrow Button.
        4. The display shows "bt-OFF" when Bluetooth is not activated.

    IMPORTANT NOTE: The Z1 Auto's default firmware is compatible with iPhone and iPad only. The newest firmware can be downloaded and installed on the Z1 Auto to make it compatible with newer Android devices. See instructions below for steps to add the new firmware version.

    26dBA Operation

    The Z1 Auto operates at 26 dBA making it one of the quietest machines available. To illustrate the sound level of 26dBA, the sound rating of a room fan set to low speed as heard from 3 feet away is over 35dBA.

    Advanced Features

    • Z-Breathe Pressure Relief: Z-Breathe is a comfort feature offering a reduction in the air pressure at the time of exhalation. The drop in the airstream pressures makes breathing during therapy a more natural process. Z-Breathe can be set to one of three levels:

      1. Z-Breathe set to 1 = gentle pressure relief at the time of exhalation
      2. Z-Breathe set to 2 = moderate pressure relief at the time of exhalation
      3. Z-Breathe set to 3 = large pressure relief at the time of exhalation

      For more information about Z-Breathe, please see the Z-Breathe Information Sheet.

    • Auto Altitude Adjustment: The Z1 Auto machine automatically adjusts as needed for changes in elevation. It can operate from sea level up to 8,000 feet above sea level.

      • Leak Compensation: The Z1 machine adjusts the pressure to account for minor air leaks to help ensure the prescribed pressure is being met during therapy. If an excessive air leak is detected the word "REMINDER" is displayed on the screen. Correct the leak to remove the word "REMINDER" from showing on the screen.

    Ramp Feature

    The Z1 Auto machine includes a ramp feature that can be set from 0 to 45 minutes. This allows the therapy pressure to begin at a lower starting pressure and work up to the prescribed pressure. Many CPAP users find this to be a more comfortable way to fall to sleep. The machine can be set with or without a ramp time.

    SD Cards Not Intended For Use with Z1 Machines

    Please Note: The manufacturer recommends users not to use an SD card with the Z1 series of machines. The SD slot is intended for manufacturer testing purposes only. If the card is used, it may cause the machine to malfunction. Data accumulation is not affected by the SD slot as it is not intended to generate sleep results. Instead, use the Bluetooth connection or use the USB cable along with the Data Viewer Software to view personal sleep records on the machine.

    Plug Power Cord Into AC Adapter BEFORE Plugging Into Wall Outlet: Follow these steps for powering the Z1 Machine:

    • Initially, DO NOT plug the AC power cord into a wall outlet.
    • Step 1: Plug the AC power cord into the AC Adapter.
    • Step 2: NOW Plug the AC power cord into a wall outlet.
    • Step 3: Plug the pin end of the AC Adapter into the Z1 machine.
    • When powering up the Z1 machine displays start messages.
    • Approximately 10 seconds later, the display shows "Pressure cmH2O 0.0" and the machine is in standby mode.

    Sound Level Tips

    Although the Z1 CPAP machines have a low decibel rating of 26 dBA, some users report a noticeable pitch from the machine’s motor, which may be a result of its reduced size. Unlike larger machines, smaller travel CPAPs have less internal room and components to absorb the sound of the motor. To help reduce the sound of the motor, consider adding the Q-Tube In-Line CPAP Muffler Kit to the device.

    Tube Adapter Tips

    To avoid damange to the silicone gasket connection on the machine, please attach and detach the tube adapter gently from the machine. Using excessive force can create tears or damage to the silicone gasket which could prevent the machine from operating properly.

    HME Compatibility Tips

    Machine: The Heat Moisture Exchange Unit for CPAP Machines is universal, and it is compatible with all CPAP, APAP, or BiPAP machines.

    Mask: When selecting a mask, please note the Heat Moisture Exchange Unit for CPAP Machines will not work with masks that have a short tube extended from the mask frame. The HME must be very close to the moisture of exhaled air to function properly. It must be connected to a mask with a simple elbow in order to give optimal results.

    Slim Style 15mm Tube: The Z1 Auto Machine requires the use of a Slim Style, 15mm tubing. It comes packaged with a 4 Foot Slim Style tube. Alternatively, any 15mm 6 Foot tube may be used. Here are some examples of 15mm 6 Foot tubes: Respironics Pure White Thin 6 Foot Performance CPAP/BiPAP Tubing (15mm) and Thin Style 6 Foot BreatheLight Tubing.

    Bluetooth Connectivity Note: The manufacturer notes only a very small amount of connectivity is used by the Z1 Auto and Nitelog application making it highly tolerant of reductions in wireless quality of service. Performance of Nitelog will be affected only if service is entirely lost.

    OPTIONAL Z1 PowerShell Use & Charging: Information about charging the battery and using the PowerShell is available on that product page: CLICK HERE.

    The Z1 battery must be inserted into the PowerShell for charging. The Z1 Auto machine is not required to be in the PowerShell to charge the battery. When the Z1 machine is inserted in the PowerShell with the battery, the charge information is displayed on the machine screen. The charge level of the battery cannot be determined if the machine is not inserted in the PowerShell. Battery run time varies based on the pressure setting of the machine.

    PLEASE NOTE: When not in use, the manufacturer suggests removing the battery from the PowerShell, as battery charge will be depleted if connected.

    Backup Battery Configuration:

    Please Note: In a situation where a power outage is expected but not certain, the battery can be used as a failover. While AC power is available the battery will not loose life cycles.

    The Z1 Travel CPAP machines can be connected to the OPTIONAL Powershell and to AC power without causing the lifespan of the battery to decrease. The battery is designed to provide AC power to the machine while it is available, and transition immediately to DC power from the battery if AC power should fail. Once AC power is restored, the battery will begin providing that power to the machine again.

    OPTIONAL PowerShell & Battery Charge Bars: When the OPTIONAL PowerShell and battery are used with the Z1, the machine display shows the amount of power remaining in the battery using a battery icon with solid bars. When the battery is charging the bars in the battery icon flash.

    • 1 Solid bar = 10-25% charge remaining
    • 2 Solid bar = 25-50% charge remaining
    • 3 Solid bar = 50-75% charge remaining
    • 4 Solid bar = 75-100% charge remaining

    Length of HME Use: The manufacturer of the Z1 originally found the HME to only be suitable for one night's use, however after further research and testing it has been approved for up to seven night's usage. Be aware that some packaging and documentation may still state 24 hours, but all Z1 HME's may be used for up to 7 nights.

    Z-Breathe Settings: The pressure relief setting Z-Breathe can be set to 1, 2 or 3. Please Note: Z-Breathe CANNOT be turned off. Set to 1 to receive the lowest drop in pressure at the time of exhalation.

    OPTIONAL Small Carry Bag: The Z1 Auto includes a fabric pouch measuring 15 1/4 inches long and 10 inches wide with a drawstring closure. The Small Carry Bag is approximately 6 inches high by 5 1/2 inches wide by 5 inches deep and can hold the Z1 machine, power supply with outlet plug cord and hose adapter. It is padded on all sides including the top and has a removable shoulder strap, carry handle and belt handle. This bag WILL NOT hold a hose or mask.

    Display Showing "REMINDER": The LCD of the the Z1 Machine will display "REMINDER" when there is an excessive air leak. This may display when a hose or mask is not attached or if the hose or mask cushion is damaged. The machine setting menu cannot be entered if a hose is not attached to the machine.

    Not For Use With Supplemental Oxygen: The Z1 machine is NOT for use with supplemental oxygen or any other added gas. Do not use an oxygen tank or concentrator with the Z1 machine.

    Disposable Air Filter: The Z1 uses a disposable air filter. It should not be washed and reused. Install the filter prior to using the Z1 machine. The filter should be changed monthly and the used filter discarded.

    Solar Charge: At this time the Z1 Machine and PowerShell CANNOT be charged using solar power.

    Enjoy the freedom of integrated battery power with the Z1 PowerShell with Extended Life Battery. The PowerShell connects the Z1 Auto CPAP machine and the battery in a compact, portable bundle.

    Interested in a battery back up which kicks on in the event of a power failure? The Z1 machine and PowerShell offers it. Place the Z1 machine and battery in the PowerShell and plug into the wall outlet. The machine will be powered by the AC electricity, battery power will NOT be used. However, if there is a disruption in the AC power supply the battery power will automatically kick on to power the CPAP, creating a failover system.

    Manufacturer tests showed the Overnight Battery included with the PowerShell powered the Z1 CPAP Machine set to a pressure of 14cmH2O for 8 hours of use. Actual battery run time will vary based on machine pressure, machine settings, and personal breathing, with a manufacturer reported maximum run time of 14 hours. Manufacturer reports the battery will deliver at least a "full night." Manufacturer defines "full night" as 4 hours. Replacement battery modules are available for purchase.

    The battery is charged in the PowerShell, with or without the machine in the shell. When charging the battery with the machine inserted into the shell the charge level is displayed on the machine's screen. Charging the battery without the machine in place does not provide information on the charge level. Please Note: The battery is NOT charging when the Z1 Auto CPAP machine is turned on and blowing. The battery charges only when the machine is powered off.

    Freedom Battery with 150W Sine Wave Inverter:

    The Z1 Travel Machine is also compatible with the Freedom Travel Battery Pack ONLY if the 150W Sine Wave Inverter is purchased separately. The Z1 Machine cannot be used directly with the Freedom battery and requires an inverter; however, please keep in mind that using an inverter will reduce the battery's run-time by half the projected amount.
