7. Maintenance
In order to ensure safety and a problem-free operation, the UV flood lamp should
undergo regular service by a customer service facility authorized by ourselves.
Aside from inspecting the technical equipment, the lamp intensity is also
calibrated and a new exposure chart is created. This maintenance should be
performed at least every two years or after every 400 hours of operation,
whichever comes first.
8. Lamp replacement
The UV lamp may only be replaced by a trained service technician.
Always unplug the unit from the wall outlet prior to beginning any
maintenance tasks!
To replace the lamp, the protective screens must first be unscrewed. Only OEM
lamps and lamp starter ballasts may be used in order to maintain the unit’s
operating specifications. The UV device must be recalibrated after every lamp
replacement. The UVA or UVB tube are inserted into its socket. When replacing
a lamp, replace the starter as well.
Important safety information:
Care must be taken to ensure that the UVA and UVB lamps are not
interchanged, as exposure at an incorrect spectrum could result in the
patient being burned!
9. Care
The UV device should be regularly cleaned as follows.
Description Interval Cleaning means
Outer device casing every 1-5 days Damp cloth
Acrylic protection panels as required Only special acrylic cleanser
During all cleaning work the mains supply is to be disconnected for safety
reasons !
Cleaning of the outer casing:
For cleaning, a damp cloth or a cloth impregnated with plastic cleanser is to be
used. No water may run into the appliance. Do not use any cleansers which
attack the plastic coating.
Cleaning of the acrylic protection panels
The acrylic protection panel is as a rule only cleaned from the outside, where
fingerprints and other residues become visible.
The panels should therefore be cleaned regularly, so that the quality of the
radiation spectrum does not change considerably.
