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.Realize that there may be some pressure drop on a 100′ line set, and there should be very little in a 10′ line set. Make some allowance according to the situation. If the system runs VERY low or VERY high suction pressure or superheat readings that are way out of range, it is very unlikely that adjusting the valve will remedy it.Oct 22, 2018 · The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling …R410 Temperature/pressure chart for low/high side. psi: Pound per square inch, unit of pressure The temperature pressure charts in HVAC help in troubleshooting various problems with air conditioning systems such the the head and suction pressure, liquid lines and troubleshooting superheat and subcooling.Let's get started and see what we can do.Most manufacturers recommend charging by super heat and subcoolimg rather than pressures alone,and will vary slightly by manufacturer but as a rule low side of about 110 and high side about 280at 70 degree ambient.
