Cleaning

Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is therefore
impossible to specify precise cleaning intervals for the =!C 250 Arypton/4ntour. Cooling fans suc7 in
airborne dust and smo7e particles, and in extreme cases fixtures may reYuire cleaning in less than 50 hours
of operation. 4nvironmental factors that may result in a need for freYuent cleaning include:
D ]se of smo7e or fog machines.
D eigh airflow rates (near air conditioning vents, for example).
D Qresence of cigarette smo7e.
D !irborne dust (from stage effects, building structures and fittings or the natural environment, for example).
If one or more of these factors is present, inspect all fixtures within their first 50 hours of operation to see
whether cleaning is necessary. Chec7 again at freYuent intervals. This procedure will allow you to assess
cleaning reYuirements in your particular situation.
