Normal 410a pressures
Connect the gauges center yellow hose to the R410a refrigerant tank. Connect the adapter to the blue low pressure line on the gauges. As quickly as possible, attach the blue hose with the adapter to the mini split port. A small amount of refrigerant will come out, which is normal; simply attach the hoses as quickly as possible to minimize the loss.If the duct system was designed for a required airflow for heating of 1,065 cfm at a 0.3 external static pressure (ESP in inches of water column [IWC]) it would draw 154 Watts. However, the cooling system requires 1,300 cfm, which increases the static pressure to slightly above 0.4 ESP and increase the operating wattage to slightly over 179 watts.Normal eye pressure is between 12 and 22 millimeters of mercury, state the Glaucoma Research Foundation. The method of measuring eye pressure is called tonometry and is done with a device called a tonometer.
