Once a system has been converted to R-421A. Based on historic sliding cardboard charge calculators, this app allows contractors to easily calculate the correct system refrigerant charge for R-22, R-410A, R-32, R-407C, R-134a, R-452B. LIQUID TEMP (°F) DESIGN SUBCOOLING (°F) LIQUID GAGE PRESSURE (PSI) From Dwg. This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate subcooling on a TXV system. The same temp on the 410A chart shows your high side pressure should be about 335 psi. Correct the airflow problem and check the charge again. ith the power off, open the front panel of the MAX indoor unit. checking the charge- vapor/suction operating pressures, what is too low! p/t chart on the manifold gauge set is calculated. refrigerant charging No : Not Substitutable for R410A Yes : Substitutable for R410A No 1/2in. Subcooling using the R-410A Refrigerant Charging Chart (in the cooling mode) is the only recommended method of charging between 55°F and 120°F ambient temperatures. have had problems with defrost no correctly working blub placement freezing up not detection all the timelet me no if this helps. These are only exam-ples of what the manufacturer’s may recommend. When every HVAC technician looks at gauges, he or she either looking for pressure or temperature.
