Environmental Conditions
Ratings and duty cycles of CT subsystems apply if site environment meets the standards of this
section. Maintain environmental conditions listed below at all times – including, for example,
overnight, weekends and holidays. Shut down the CT system if air conditioning is not working.
When system is shut down for major repair, air conditioning may be shut down also.
NOTICE Silver, copper, gold films used in the CT system are especially sensitive to the presence of
sulfide, chloride and nitrate contaminates. Sulfur is the most damaging. If high levels of
contaminates exist site may want to consider appropriate air filtration systems.
