Yes you can, We have a cooler on 404a. More common on Med-temp racks though. Go wash out that condenser real WELL and check for air in the condenser. The refrigerant isnt your problem. Reply. 06-15-2006, 07:42 …The valve needs to be selected based on the compressor capacity at it's normal operating temperatures and pressures with consideration given to liquid entering temperature and pressure drop across the valve. Temperature difference is also an important consideration. The rule of thumb for setting superheat on a common mechanical TX valve is 10°F.See full list on learnmetrics.com
