Description
The Carrier 339939-702 Switch Pressure Assembly is an essential part of the HVAC systems that measure high pressure. It also changes the pressure at which the system operates to safe pressure and thus helps to avoid system damage and maintain the better performance. This switch which is normally fitted in air conditioning units and heat pumps, safeguards compressors and other vital parts by stopping the operation of the unit when pressure levels are high. This safety feature provides a longer life to HVAC equipment and reduces maintenance costs.
