to discolor and degrade
As Needed
1. Clean the exterior of the Z2 with a soft damp cloth and mild detergent and wipe
clean. Never submerge the Z2 in water. Do not allow soap or water to enter the Z2.
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 Z2 uses a specially designed Filter that is only available from
your retail medical supplier or at www.smallcpap.com.
WARNING: Do not attempt to use any air filter which is not supplied
by Breas Medical for the Z2. The Z2 is designed to only work with
approved materials. A filter which is not approved may cause damage to
the Z2 from overheating.
CAUTION: Do not operate the Z2 without the Filter. The Z2 must
operate with a filter installed; failure to do so may damage the Z2 and
allow impurities into the respiratory system.
USB Firmware Upgrade
Z2 firmware upgrades and instructions can be found on www.breas.us when they become
available.
