5.1.1 Creating a Flare Fitting
WARNING
• Do not allow the refrigerant to leak during brazing. If the refrigerant is combusted, it generates a
toxic gas that can cause physical injury or death.
• Do not braze in an enclosed location, and always test for gas leaks before/after brazing.
• After brazing, check for refrigerant gas leaks.
NOTE
1. Do not use kinked pipe cause by excessive bending in one specific area
on its length.
2. Braze the pips to the service-valve pipe stem of the outdoor unit.
WARNING
Risk of refrigerant leaks. Can cause equipment malfunction, injury, sickness and death from
suffocation due to oxygen depletion in closed, non-ventilated areas.
When selecting flare fittings, always use a 45° fitting rated for use with high-pressure refrigerant
R410A. Verify that all fittings comply with local, state, or federal standards.
NOTE
One of the main causes of refrigerant leaks is defective flared connections.
Create flared connections using the procedure shown in Figure 5-1 and steps
that follow.
