Due to the additional volume added by the coalescing filter, there is an exception to the Response Time specification for the 480L: when equipped with the Sample Conditioner option, a 480L instrument’s Response Time is <60 seconds to 95%.
The permeation material is a Teflon™-type compound and has only a minimal effect on the ozone concentration in the sample stream. When the 480L is equipped with this option, the unit has been calibrated at the factory to compensate for any ozone loss in the permeation dryer.

7.1 MAINTENANCE SCHEDULE Table 7-1 below outlines the suggested maintenance procedures and intervals for ensuring the 480L continues to operate accurately and reliably. These intervals are based on continuous (24 hours a day – 7 days a week) operation. These intervals may be lengthened for intermittent operation.
High voltage may be present when power is connected to the instrument. Figure 7-1 shows the internal layout of the 480L as reference in the procedures that follow. Note the locations of the Power Supply and the Electrical Terminal Block where high voltage (line voltage) may be present when power is connected to the instrument.
