Cleaning
We suggest using “Monk” Brand Wipes
for exterior cleaning as they disinfect and will not harm any
ultraviolet or light transmitting surfaces. These wipes are available for purchase through Daavlin. When
dusting the unit we recommend using a feather duster or a similar non-abrasive cleaning device.
16.3
Cleaning of the Filter
A trained technician should clean the internal filters and cavities of the machine annually. Do not
attempt to clean these filters without proper training, as certain solutions may damage the filters.
Only
Daavlin authorized personnel should perform this function.
Allow the filters to cool down.
Use a vacuum to remove dust from black filters on both sides of each lamp column.
Depending on the frequency of use and the location of the unit, the filters may collect dirt. This will impair
UV intensity.
16.4
Relamping
Only Daavlin authorized personnel may carry out lamp replacement
The UV output of the lamps typically degrades to unacceptable levels after 500-800 hours of use. Only
use the replacement lamps specified in this manual when relamping. Although other lamps may fit and
light, they may also produce excess amounts of UVB which could be harmful to the patient. Always return
lamp filters to their original position after relamping. Follow all federal and local regulations when
relamping and disposing of discarded lamps.
Note:
Always measure lamp intensity before and after lamp replacement. It is important to notify
everyone concerned that the lamps have been replaced as patient exposure times may need adjusting.
