Mains power quality should be that of a
typical commercial or hospital environment.
If the user of The KN-4000 series UV
Radiation Treatment System requires
continued operation during power mains
interruptions, it is recommended that The
KN-4000 series UV Radiation Treatment
System be powered from an uninterruptible
power supply or a battery.
