Pur•Chek™ 1 Introduction 1.1 How to Use This Manual This manual provides important information on how to operate and maintain Bacharach’s Pur•Chek™ HVAC Advanced Refrigerant Identifier. To assure operator safety and proper use of the Pur•Chek™, please read, understand, and follow the contents of this manual. 1.
Pur•Chek™ 1.2.2 General Warnings & Cautions • • • • • • • • • • Always inspect the sample hose before each use. Replace the hose if it appears cracked, frayed, obstructed or fouled with oil. ALWAYS turn the compressor off before connecting the instrument to an air conditioning system. Always wear eye and skin protection when working with refrigerants. Escaping refrigerant vapors will present a freezing danger.
Pur•Chek™ 1.5 Functional Overview Contamination of refrigerants either in storage cylinders or air conditioning systems can lead to component corrosion, elevated head pressures and system failures when utilized by unsuspecting technicians. The ability of the technician to determine refrigerant type and purity is severely hampered by the presence of air when attempting to utilize temperature-pressure relations.
