Maintenance
Purge Viewing Window/Tubes
Remove and examine the window or purge tube for deposits. If you notice a drop
in UV performance clean or replace the windows. Clean according to the
instructions given later in this chapter or replace as necessary.
Nebulizer
Check the nebulizer spray pattern with deionized water. Clean or replace the
nebulizer as necessary.
Spray Chamber
Check for leaks around the nebulizer and drain fitting. Inspect the spray chamber
for deposits and check the condition of the O-rings.
Peristaltic Pump
Check that the pump rollers are clean, not scored, free from deposits due to spills,
and move freely. Remove and clean the pump head if necessary. Replace the pump
rollers if necessary.
Periodically observe the drain tubing. Liquid should drain smoothly from the spray
chamber. If not, adjust the pump tension on the pump tubing.
Drains
Check the spray chamber drain fittings, tubing and connections and replace if
necessary.
