• The installer of the refrigeration line set must be USA Government Environmental Protection Agency
(EPA) certified in proper refrigeration handling and service procedures
• A qualified person must perform all roof or wall penetration
• Do not form unwanted traps in refrigeration lines. A service loop is not considered an oil trap.

releasing the condenser unit or evaporator unit holding charge until all line connections are finished
and the system is ready for evacuation.
• This unit contains a full charge of R449A.
1. Make and connect line set run from the condensing unit to the evaporator unit with all
specifications found in the installation specifications section. Do not overheat shut off valves on
the condenser unit or evaporator unit.
Note: Insulate entire suction line (not the liquid line) including shut off valves to prevent
condensation.
2. Leak check field joints via the evaporator unit service valves.
3. Evacuate line set via the evaporator unit service valves.
