TitleSpecification(s)Objective(s)
5.3003.5a
Insulation

 All suction or vapor refrigerant lines, will be insulated to a minimum of R-4

High-side or liquid refrigerant lines will not be insulated unless specified by the equipment's manufacturer

Ensure refrigerant lines do not gain excessive heat, or cause condensation to occur inside the building envelope Envelope The separation between the interior and exterior environments of a building that includes a combination of air and thermal barrier

5.3003.5b
Ultraviolet ( UV UV Ultraviolet ) protection of insulation

If exposed to sunlight, refrigerant line insulation will be protected from UV UV Ultraviolet degradation in accordance with manufacturer specifications, IRC IRC International Residential Code or local code

Install insulation so it does not degrade

5.3003.5c
Sizing

Refrigerant lines will be sized to meet manufacturer specifications for the installed equipment

Ensure system moves appropriate volume of refrigerant

5.3003.5d
Installation quality

Refrigerant lines will be installed without kinks, crimps, or excessive bends

Ensure system moves appropriate volume of refrigerant

5.3003.5e
Support

Refrigerant lines will be routed, supported, and secured to house in a manner that protects the line from damage by workers or occupants

Ensure refrigerant lines do not move, vibrate, or sag

Protect lines from damage
