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 be that
of a typical commercial or hospital
environment.
Mains power quality should
be that of a typical commercial or
hospital environment. If the user of
the Zen-O™ Portable Oxygen Concen-
trator required continued operation
during power main interruptions, it is
recommended that the concentrator
be powered from an uninterruptible
power supply or battery.
Power frequency magnetic fields
should be at levels characteristic
of a typical commercial or hospital
environment.
