Before checking the refrigerant charge in subcooling, the indoor and outdoor temps must both be above 70°F. This provides a heat load for the system to work with and is the minimum indoor and outdoor temps that you can accurately check the refrigerant charge at. Connect the gauges and purge the air from the hoses prior to starting the unit up.

1. Optimal Cooling. When the low side pressure operates within the recommended range for 410a, your system can efficiently absorb heat from your indoor environment. Any deviation from this range might compromise the cooling efficiency, leaving certain areas less cooled than others. 2.I apologize but the chart actually has both and I don't have anything hooked up anymore can I do it in the morning or another time tomorrow that may be good for you it's kind of hard to read the chartsit has 6 8 10 12 14 16 listed under the required subcooling temperature I believe that's for the tons and I'm not sure how many tons my unit is I've looked it up and I have to get the thermal ...New 470a refrigerant that replaces 410a refrigerant, with Do-It-Yourself kit included..... https://ebay.us/tVSqEv1 ton, cool only with Wifi & Alexa..... http...Refrigerant Pressure Temperature Chart - PT Chart for R-410A, R-134A, and R-22.

Under-reporting of weight means that, as systems leak, the leak rate looks larger. For a. 20-ton unit with 80 Pounds and leaks 10 pounds = leak rate of 12.5%. 20-ton unit with 49 pounds and leaks 10 pounds = leak rate of 20%.

Jan 22, 2024 · The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned. 357. Post Likes. Like Doug said, all new condensing units I have seen are charged for 15 feet of lineset. You have 35 feet total, 35-15=20, 20x.6=12, 12 oz to a pound should do it for ya. and with the r410A, being low 12 oz will make a real difference in cooling capacity, try to get the charge as close as possible.

The R-410A high-pressure manifold gauge and hose set must have a 4000 psig burst pressure and 800 psig working pressure. The high pressure gauge on a service manifold set has a continuous scale, usually calibrated to read from 0 to 500 psig. This does not mean the gauge set is actually rated for use up to 500 psia.6-7 years ago, my refrigeration book explained that in some instances, with the unit off, refrigerant could be added in liquid form without any issues. I forget exactly why they said to do this but it seemed like interesting thing to try. I've done so a couple of times while charging a unit that needed a lot of refrigerant and metering it in was taking awhile.One of the first steps to take is to clean and vacuum the internal coils that keep the dehumidifier running.
