SERVICING

Moisture chemically reacts with the refrigerant and oil to form corrosive hydrofluoric and hydrochloric acids. These attack motor windings and parts, causing breakdown.

The equipment required to thoroughly evacuate the system is a high vacuum pump, capable of producing a vacuum equiva- lent to 25 microns absolute and a thermocouple vacuum gauge to give a true reading of the vacuum in the system

NOTE: Never use the system compressor as a vacuum pump or run when under a high vacuum. Motor damage could occur.

SCROLL COMPRESSORS

DO NOT FRONT SEAT THE SERVICE VALVE(S) WITH THE COMPRESSOR OPERATING IN AN ATTEMPT TO SAVE REFRIGERANT. WITH THE SUCTION LINE OF THE COMPRESSOR CLOSED OR SEVERLY RESTRICT- ED, THE SCROLL COMPRESSOR WILL DRAW A DEEP VACUUM VERY QUICKLY. THIS VACUUM CAN CAUSE INTERNAL ARCING OF THE FUSITE RESULTING IN A DAMAGED OR FAILED COMPRESSOR.

1.Connect the vacuum pump, vacuum tight manifold set with high vacuum hoses, thermocouple vacuum gauge and charg- ing cylinder as shown.

3.If the vacuum pump is working properly, close the valve to the vacuum thermocouple gauge and open the high and low side valves to the high vacuum manifold set. With the valve on the charging cylinder closed, open the manifold valve to the cylinder.

4.Evacuate the system to at least 29 inches gauge before opening valve to thermocouple vacuum gauge.

5.Continue to evacuate to a minimum of 250 microns. Close valve to vacuum pump and watch rate of rise. If vacuum does not rise above 1500 microns in three to five minutes, system can be considered properly evacuated.

6.If thermocouple vacuum gauge continues to rise and levels off at about 5000 microns, moisture and non-condensables are still present. If gauge continues to rise a leak is present. Repair and re-evacuate.

7.Close valve to thermocouple vacuum gauge and vacuum pump. Shut off pump and prepare to charge.

USE REFRIGERANT CERTIFIED TO ARI STANDARDS. USED REFRIGERANT MAY CAUSE COMPRESSOR DAMAGE AND WILL VOID THE WARRANTY. MOST PORTABLE MACHINES CANNOT CLEAN USED REFRIGERANT TO MEET ARI STANDARDS.

OPERATING THE COMPRESSOR WITH THE SUCTION VALVE CLOSED WILL VOID THE WARRANTY AND CAUSE SERIOUS COMPRESSOR DAMAGE.

Charge the system with the exact amount of refrigerant. Refer to the specification section or check the unit nameplates for the correct refrigerant charge.

An inaccurately charged system will cause future prob- lems.

2.Start the vacuum pump and open the shut off valve to the high vacuum gauge manifold only. After the compound gauge (low side) has dropped to approximately 29 inches of vacuum, open the valve to the vacuum thermocouple gauge. See that the vacuum pump will blank-off to a maxi- mum of 25 microns. A high vacuum pump can only pro- duce a good vacuum if its oil is non-contaminated.

1.Using a calibrated set of refrigerant scales, allow liquid re- frigerant only to enter the high side.

2.After the system will take all it will take, close the valve on the high side of the charging manifold.

3.Start the system and charge the balance of the refrigerant through the low side.

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.
