• The temperature of the airﬂow for breathing produced by CPAP devices can be higher than

the temperature of the room. This is true of all CPAP devices. Caution should be exercised

when using your Z1 at room temperatures warmer than 90˚F (32˚C).

• Only operate the Z1 and accessories within the operating temperature, humidity and

altitude conditions speciﬁed in the Technical Speciﬁcations section of this User Guide.

• Only store or transport the Z1 and accessories within the storage and transport

temperature, humidity and altitude conditions speciﬁed in the Technical Speciﬁcations

section of this User Guide.

• Damage to the CPAP Tube may result in air leaks. If this occurs, stop using the damaged

CPAP Tube and replace immediately.

Battery Warnings and Cautions

The PowerShell comes with a removable Lithium Ion Battery. Careful attention must be paid to

the warnings and cautions described below relating to the Battery. Misusing the Battery may

cause the Battery to get hot, rupture, ignite and cause serious injury.

WARNINGS:

• Do not place the Battery in ﬁre or heat the Battery.

• Do not install the Battery backwards so that the polarity is reversed.

• Do not connect the positive terminal and the negative terminal of the Battery to each other

with any metal object (such as wire).

• Do not carry or store the Battery together with necklaces, hairpins, or other metal objects.

• Do not pierce the Battery with nails, strike the Battery with a hammer, step on the Battery or

otherwise subject it to strong impacts or shocks.

• Do not solder onto the Battery.

• Do not expose the Battery to water or salt water, or allow the Battery to get wet.

• Do not disassemble or modify the Battery. The Battery contains safety and protection

devices which, if damaged, may cause the Battery to generate heat, rupture or ignite.

• Do not place the Battery on or near ﬁres, stoves or other high-temperature locations. Do not

place the Battery in direct sunlight, or use or store the Battery inside cars in hot weather.

Doing so may cause the Battery to generate heat, rupture or ignite. Using the Battery in this

manner may also result in a loss of performance and a shortened life expectancy.

• Immediately discontinue use of the Battery if, while using, charging or storing the Battery,

the Battery emits an unusual smell, feels hot, changes color, changes shape or appears

abnormal in any other way. Contact the Human Design Medical Service Center at 1-855-

436-8729 [1-855-HDMUSA9] if any of these problems are observed.

• Do not place the Battery in microwave ovens, high-pressure containers, or on induction

cookware.
