This kit converts the instrumentís air purification system from an APU (1 month use) system to LLAPU (approximate 6 month use). Detailed, step-by-step directions with a picture diagram guide the technician through the simple conversion which takes approximately 30 minutes.
The advantage of an instrument operating in LLAPU mode rather than APU mode is it affords a much longer service interval between indicating bottle changes. An additional benefit is the instrument performs better in harsh operating environments while in LLAPU mode.
Once this kit is installed, re-order the LLAPU Refill w/Indicating Bottle kit, p/n SLK4599.
