For continued protection from fire hazard, replace only with same
type and rating of fuse.
WARNING
Use only GE parts. Only spare parts and accessories that are ap-
proved or supplied by GE may be used for maintaining or servicing
the product.
WARNING
Corrosive substance. NaOH is corrosive and therefore dangerous
to health. When using hazardous chemicals, avoid spillage and
wear protective glasses and other suitable Personal Protective
Equipment (PPE).
CAUTION
Hazardous chemicals or biological agents in UV flow cell. Make
sure that the entire flow cell has been flushed thoroughly with
bacteriostatic solution (e.g., NaOH) and distilled water, before service
and maintenance.
