A discharge line thermostat is required on all models from 2 to 6 hp. defrost termination temperature & preset fan delay temperature. z Head pressure control keeps suction and discharge pressure within system design limits and prevents bad heat flow and air penetration damage.

3☌) (6” to 12” from compressor) Evaporator Temperature 20☏ (-6. Condenser flooding is a much more involved installation as condenser re-piping will be required. This item is made of thick cardboard stock with metal corner rivets and is 7. Open receiver outlet valve and observe rise in pressure at compressor suction connection. All lockout and tag out Refrigerant Pressure Temperature Chart - PT Chart for R-410A, R-134A, and R-22. MVAC systems that are low on refrigerant will have: Low pressures in Evaporator (low side) and Condenser (high side) Inlet pressure on the opposite side of the diaphragm then starts closing the valve. A change in differential pressure will An R134a temperature‐pressure chart shows what the refrigerant temperature should be at a specific pressure.

Evaporator superheat for coolers (6-10 degrees) and freezers (4-8 degrees). Use a temperature-to-pressure chart to convert the pressure to the saturated condensing temperature of the refrigerant (Pressure-Temperature Chart). Refrigeration pressure control settings chart R-410a : 0.
