5.3.6 UV Lamp (P/N ST20009)

Normal lamp replacement frequency is suggested at least every 12

months, however, if a lamp is “burned-out” (weak or no blue glow),
replace with UV Lamp (P/N ST20009), per directions in Figure 8.

Figure 5-8: UV Lamp Replacement

To replace the UV lamp:

1. Turn off the UV lamp at the UV power supply. Remove

persulfate and acid reagent lines from containers, as well
as the sample inlet line and submerse all three (3) lines
into D. I. water to completely flush system.

CAUTION:

FAILURE TO DO SO MAY RESULT IN ACID BURNS,
CLOGGED REACTOR. FLUSH FOR 30 MINUTES.

CAUTION:

USE ONLY P/N ST20009 UV LAMP TO ASSURE
PROPER 185 MM AND 254 MM POWER SPECTRAL
DENSITY AND PROPER OXIDATION EFFICIENCY.
