Take care when handling the H5i as the water/water tub may be hot. Allow 10 minutes for the
heater plate and any excess water to cool.
•
The H5i should only be connected or disconnected when the water tub is empty.
•
Make sure that the water tub is empty before transporting the H5i.
•
Do not operate the H5i on an aircraft as water may enter the device and air tubing during

If liquids are inadvertently spilled into or on the H5i, unplug the device from the power outlet.
Disconnect the H5i from the device and allow it to drain and dry before re-using.
