Between each treatment
Dusting of the unit and lamps
Once a month

lamps and protective acrylic
Annually (behind the lamps)

Every 100 hours or once a year (whichever occurs first) and
when lamps are replaced
Replace lamps
Every 300 to 500 hours of usage
Cleaning
We suggest Daavlin’s DermaClean wipes or spray as they disinfect and will not harm any ultraviolet or
light transmitting surfaces. If using DermaClean spray, spray the cleaner on a soft cotton cloth, then
wipe the surface rather than spraying the cleaner directly on the surfaces.
Note:
Do not clean the acrylic shield on M or 1 Series devices or reflective surfaces on any device
with paper towels as they may scratch the surface.
On devices with exposed lamp areas (7, 2 and UV Series), the lamp area can be cleaned by carefully
vacuuming with the grid installed. Occasionally it may be desirable to remove the lamps and grid (or
plastic lamp guard on M and 1 Series models) for a more thorough cleaning of the lamps and
reflectors. Refer to the Lamp Replacement instructions that are specific to your device on how to
remove the grid or acrylic and lamps, as well as other important information on how to ensure that the
lamps are safely and correctly replaced.
Lamp Replacement
Lamps may need to be replaced due to burnout or because their energy output has decreased to the
point that you may no longer be receiving an effective treatment.
DO NOT REPLACE UVB LAMPS INDIVIDUALLY. ALL UVB LAMPS SHOULD BE REPLACED AT
THE SAME TIME TO AVOID UNEVEN TREATMENTS OR BURNS. PLEASE CONTACT THE
DAAVLIN SERVICE DEPARTMENT PRIOR TO REPLACING YOUR LAMPS TO OBTAIN
IMPORTANT INFORMATION ON HOW THE OUTPUT OF YOUR UNIT WILL BE AFFECTED BY
THE CHANGE.
Because of differences between brands, replace lamps with the same brand as originally installed. A
lamp replacement guide is provided on page six (6).
Whenever the lamps are changed in your device, it is important to reset the lamp age to zero.
Instructions for this procedure follow:
