*Optional 25% or 50% reduced capacity ¾" (20 mm) plugs are available for unusually low loads if requested.
† –40F (–40°C) and –20F (–28.9°C) capacities are based on a two stage system.
For liquid overfeed evaporator suction between normal 2:1 to 5:1 rate, add 20% to the evaporator load or use the next larger port
size to accommodate liquid volume accompanying the suction gas and to reduce impact velocity.
Conditions: Capacities are based on the evaporator temperatures shown and +86F (+30°C) liquid. R717: For each 10F (5.6°C) lower
liquid temperature, increase the above table capacity by 3%. R22: For each 10F (5.6°C) lower liquid temperature, increase the above
table capacity by 5%. To convert for R134a, multiply the R22 table values by 0.73 (accuracy within 8%). For other refrigerant
capacities and suitability, contact the factory.
