PIPING INSTALLATION
Piping Connections to Outdoor Unit
1. Remove service valve cover (if provided) to access
the service valves and refrigerant ports. The outdoor
unit refrigerant port sizes vary with unit size. See
System Requirement Section for refrigerant port sizes.
2. Carefully bend and adjust length of refrigerant
pipes to meet outdoor unit service valves
connections with proper tools to avoid kinks.
NOTE: Use proper techniques to cut and re-flare refrigerant pipes, if required.
An R410A Flaring Tool is required for re-flaring refrigerant pipes.
An adapter pipe may be required to transition from the indoor unit to the outdoor
unit refrigerant port. Piping adapters are provided with some models. See table
below for factory provided piping adapter quantity and size:
