The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.1 3/8. 1 5/8. 1 5/8. 1 5/8. Refer to DuPont Refrigerant Expert, Version 2.0 for actual velocities and pressure drops. Equivalent length is actual length plus friction losses caused by fittings and accessories. Line sizes are expressed in outside diameter of type "L" copper tubing. Line sizes are calculated at rated full load system capacity.The larger issue is how piss poor the resolution is on the pressure scale on analog gauges, especially with the larger pressure scale for R-410a. The normal operating pressure range for R22 tends to fall into the first 1/3 of the gauge travel on the combo R-410a/R-22 gauges, which tends to be less accurate than the middle 1/3 of the gauge travel.Both are HFC refrigerants. They have zero ozone depletion potential. Major differences are: R32 is a single component refrigerant while R410A is a zeotropic blend.

Trying to charge with vapor will make you an old man before your time. It takes way to long. Also R-410A is made up of more that one chemical so swish the tank around and charge with liquid.Remove the plastic sheeting and replace the low-voltage wire. If the pump operates correctly, you can now set it back to heating mode. The superheat method helps to charge a heat pump in temperatures as low as 20F. However, there are more accurate methods such as charging by weight and charging by discharge temperature.

How to Add 410A Refrigerant? To add 410A refrigerant to a system, start by breaking the vacuum on the system and supplying liquid R-410A to the liquid line or receiver port.
