By law we are unable to distribute the instructions to change the pressure settings for patients. If you have questions on the appropriate pressure on your device, please contact your prescribing doctor and/or sleep specialist. If you are a prescribing doctor and/ or sleep specialist, call us at 855-436-8724 so we can send you the clinician’s manual.

The device must be returned to replace the silicone outlet tube.  Please contact the home medical equipment supplier or website you purchased your device from, and let them know your unit needs to be returned to the manufacturer. If you purchased it from hdmusa.com or smallcpap.com please call us at 855-436-8724.

The dim light is on a timer and should turn off after a few moments. Unfortunately, there is no way to change the timer on the backlight of the LCD screen.

When the Z1 or Z2 is in standby mode, the screen reads 0.0 in the pressure area. If the screen is not displaying 0.0 when turning your machine on, would indicate that it needs to be returned for repair. Please contact your provider, and they will advise you on what steps to take.

If the display screen shows your pressure, and the fan has not started blowing air within thirty seconds, then the blower has failed and the machine should be replaced.  Please contact your provider and they will advise you on what steps to take.

The minimum voltage you will need to run your Z1 or Z2 device is 14.4 volts.

It is an activated oxygen cleaning system that completely sanitizes your CPAP without any water or chemicals and kills 99.9% of all germs and bacteria in the hose and mask.  Please see the SoClean instructions for further information.

The Z1 and Z2 run on electricity from 100-240V which means you will not need a converter for international travel. You will only need a plug adapter to fit the right configuration for the country you are visiting.

Our tubing comes in two different lengths- 4 feet and 6 feet slim style. They are 15 mm in diameter. You can also use standard tubing with the Z1/Z2, which is 19-22 mm diameter.

The most common cause of a pressure increasing, beyond what is necessary, is a leak in the system/mask. It may be a leak in the connections to the mask, or the hose.  Please check to make sure these connections fit tightly.

Another reason is an excessive leak at the mask.  Please make sure you have a proper seal between the mask and your face.

Check the connection of the tube adapter and the outlet tube (the rubber piece where the tube adapter connects to the machine). If the tube adapter is not properly seated in the outlet tube, the pressure sensor may not be getting the information it needs to regulate the pressure. Also check to make sure your outlet tube is not torn. If it is torn, the device will need to be returned to be repaired.

The last reason could be the Z1/Z2 may be sensing an obstruction, which reads as an apnea, and thus increasing the pressure.  This could be caused by congestion, or a mask system that has very low flow rate. If you have a mask with very low flow rate, such as some of the very small nasal pillow masks, you may want to try a mask with less restriction such as a nasal mask.  If none of the above are successful, please contact the provider you purchased your Z1/z2 from.
