The material in this lesson represents a basic overview of heat pump systems. The operating capacity and performance of any heat pump system is dependent on attention to detail during the installation process. 

Those measures include: 

• Cleanliness of all heat exchange surfaces 
• Safeguards preventing contamination of the refrigerant circuit during assembly and brazing 
• Proper evacuation of all moisture and air from the refrigerant circuit 
• Adherence to all OEM requirements in properly charging the refrigerant system 
• Confirmation the system is operating at the design air flow prior to refrigerant charge

Beyond quality in installation, due diligence is also required in ensuring:
