environment –
guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the
relative humidity should be
at least 30%.
Mains power quality should
be that of a typical
commercial or hospital
environment.
Mains power quality should

If the user of the
VPAP Malibu requires
continued operation during
power mains interruptions,
it is recommended that the
VPAP Malibu be powered
from an uninterruptible
power source
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment
