Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component.
Important Isocyanate (ISO) Information Important Isocyanate (ISO) Information Isocyanates (ISO) are catalysts used in two component materials. Isocyanate Conditions Keep Components A and B Separate Spraying or dispensing fluids that contain isocyanates creates potentially harmful mists, vapors, and Cross-contamination can result in cured material in atomized particulates.
Important Isocyanate (ISO) Information Moisture Sensitivity of Changing Materials Isocyanates NOTICE Exposure to moisture (such as humidity) will cause ISO Changing the material types used in your equipment to partially cure, forming small, hard, abrasive crystal requires special attention to avoid equipment that become suspended in the fluid.
Usage Usage Over Pressure Protection The XPs-hf proportioner is a plural component sprayer that can mix and spray most two component epoxy and urethane protective coatings. It is a fixed-ratio system, where XP lowers can be changed to reconfigure the system to different volume mix ratios or spray Mechanically linked pumps can create excessive fluid pressures.
