NOTE: The Flushing Method using R-11 refrigerant is no longer approved by Goodman® Manufacturing Company, L.P.

Suction Line Drier Clean-Up Method

The POE oils used with R410A refrigerant is an excellent sol- vent. In the case of a burnout, the POE oils will remove any burnout residue left in the system. If not captured by the refrig- erant filter, they will collect in the compressor or other system components, causing a failure of the replacement compressor and/or spread contaminants throughout the system, damag- ing additional components.

Use AMANA® brand part number RF000127 suction line filter drier kit. This drier should be installed as close to the com- pressor suction fitting as possible. The filter must be acces- sible and be rechecked for a pressure drop after the system has operated for a time. It may be necessary to use new tub- ing and form as required.

NOTE: At least twelve (12) inches of the suction line immedi- ately out of the compressor stub must be discarded due to burned residue and contaminates.

1.Remove compressor discharge line strainer.

2.Remove the liquid line drier and expansion valve.

3Purge all remaining components with dry nitrogen or car- bon dioxide until clean.

4.Install new components including liquid line drier.

5.Braze all joints, leak test, evacuate, and recharge system.

6.Start up the unit and record the pressure drop across the drier.

7.Continue to run the system for a minimum of twelve (12) hours and recheck the pressure drop across the drier. Pres- sure drop should not exceed 6 PSIG.

8.Continue to run the system for several days, repeatedly checking pressure drop across the suction line drier. If the pressure drop never exceeds the 6 PSIG, the drier has trapped the contaminants. Remove the suction line drier from the system.

9.If the pressure drop becomes greater, then it must be re- placed and steps 5 through 9 repeated until it does not exceed 6 PSIG.

NOTICE: Regardless, the cause for burnout must be deter- mined and corrected before the new compressor is started.

S-122 REVERSING VALVE REPLACEMENT

Remove the refrigerant charge from the system.

When brazing a reversing valve into the system, it is of ex- treme importance that the temperature of the valve does not exceed 250°F. at any time.

Wrap the reversing valve with a large rag saturated with water. "Re-wet" the rag and thoroughly cool the valve after each braz- ing operation of the four joints involved. The wet rag around the reversing valve will eliminate conduction of heat to the valve body when brazing the line connection.

The use of a wet rag sometimes can be a nuisance. There are commercial grades of heat absorbing paste that may be sub- stituted.

After the valve has been installed, leak test, evacuate and re- charge.

R-410A specifications

Goodman Manufacturing, a well-respected name in the HVAC industry, has made significant advancements with their R-410A refrigerant technology. R-410A, a hydrofluorocarbon (HFC), has positioned itself as a superior alternative to the older R-22 refrigerant, which has been phased out due to its ozone-depleting properties. Goodman’s commitment to energy efficiency and environmental sustainability is well reflected in their use of R-410A in their air conditioning and heat pump systems.

One of the main features of Goodman’s R-410A systems is their exceptional energy efficiency. The R-410A refrigerant operates at a higher pressure than R-22, which allows for better heat transfer and improved cooling capacity. This results in reduced energy consumption and lower utility bills for consumers. Goodman’s air conditioning units designed for use with R-410A are often rated with high Seasonal Energy Efficiency Ratio (SEER) ratings, making them an eco-friendly choice for residential and commercial applications.

Another notable technology employed by Goodman is their commitment to reliable performance through advanced compressor designs. Goodman's scroll compressors are optimized for R-410A, ensuring quieter operation and reducing vibration levels. These compressors are known for their efficiency and longevity, making them a favorite among homeowners seeking dependable and durable climate control solutions.

Goodman's multi-stage cooling systems that utilize R-410A offer precise temperature control and enhanced comfort. By controlling the speed of the compressor, Goodman’s units can adjust output according to the heating or cooling demand, maximizing comfort while minimizing energy waste. This adaptability not only enhances indoor air quality but also contributes to a greener environment by using less energy.

Furthermore, Goodman incorporates high-tech diagnostic controls into their systems. These controls provide real-time performance data, allowing homeowners and technicians to monitor system status and troubleshoot issues more easily. By using R-410A combined with these innovative technologies, Goodman emphasizes reliability and user-friendly operation.

In conclusion, Goodman Manufacturing’s use of R-410A refrigerant reflects their dedication to efficiency, reliability, and environmental stewardship in HVAC solutions. The combination of advanced compressor technologies, high energy efficiency, and innovative controls solidifies Goodman’s reputation as a leader in the industry, offering homeowners and businesses the comfort and peace of mind they deserve.
