Special considerations must be taken when installing condensers in cooler climates. During the colder weather, a winterizing valve should be utilized to maintain head pressure. This valve is actuated by a pressure difference between its inlet and outlet. The figure shows a “Winterstat” brand. Other valves may be used such as a “Headmaster” valve. If system pump-down is a desired feature, the receiver must hold the normal refrigerant charge plus the condenser charge with the bypass valve operating ̶ that is, partially open or intermittently opening and closing.EXCERPT FROM “TOOLS, CONTROLS AND TROUBLESHOOTING“, available from the ONLINE STORE at RSES.ORG.

Course Description: This class will focus on comparing and contrasting the most popular and widely used R22 alternatives in use today. Additional time will be spent defining the true meaning of “drop in replacement” and why it is illegal to mix refrigerants. Information will also be provided on the current status of the R-22 phase out that will be completed December 31, 2019. Finally, EPA required refrigerant recovery practices, reclamation, and EPA compliant record keeping of recovered refrigerants will be discussed.
Class Instructor: Bill White, owner of Refrigerant Solutions, Inc. & Chairman of the State of Alabama Heating, Air Conditioning, & Refrigeration Board, brings over 35 years’ experience in electric utility marketing programs, wholesale HVAC distribution, and refrigerant management.
- Before servicing any system, check the compressor and system labeling to determine whether the system being serviced contains a flammable refrigerant.A compressor designed for flammable refrigerant use should have the refrigerant designation printed on the compressor serial label, and may also display a separate flammable refrigerant label (see below):
