What is the condensing temperature of R404a?
Refrigerating capacity Conditions chosen are 40°C condensing temperature, 10 K superheat, no sub-cooling, variable evaporating temperature.
What should the high and low side pressures be for R-404A?
look for pressures around 18-20 low side and 200 ish high side.
What should the pressures be on a walk in freezer with 404A?
If it works properly, it should be running at 10 to 20psig. The high side should be around 180.
What pressure should 410A be while not running?
For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used. Use only DOT recovery cylinders rated for 400 psi or higher when recovering R-410A.
What is a good superheat for 404A?
Emerson recommends a minimum of 20F (11C) superheat, measured on the suction line 6 inches (152mm) from the suction valve, to prevent liquid refrigerant floodback.
How do you charge 404A refrigerant?
R-404A and R-507 refrigerant cylinders have a dip tube and liquid is charged with the cylinder upright. Break the final vacuum by charging liquid refrigerant into the receiver outlet valve access or the area of liquid line downstream from the receiver outlet.

How do you know if your PT is positive?
A line on a pregnancy test may show a positive result if:
- There is visible dye in the line, even if the color is faint.
- The line appears within the period specified on the instructions, which is usually 3–5 minutes.
- A woman has taken an early-result test at least 11 days after ovulation.
How do I read a PT?
READING THE RESULT If two coloured lines appear on the test strip, you are pregnant. One line may appear lighter than the other, but they will both be the same thickness. A faint line is more likely to occur when you are testing early and your hCG levels are low. See Questions 5 and 7 in the frequently asked questions.
What is 410A operating pressure?
What happens if you add too much refrigerant?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.
What happens if too much refrigerant?
The Compressor: Excess refrigerant creates a danger called slugging. This is when extra refrigerant floods into the piston cylinders of the compressor when in a liquid state. Slugging can create many different problems such as broken valves, broken connecting rods, and significant damage to the compressor.
