Refrigeration line installation: 7/8" OD suction line / 3/8" OD liquid line

• 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.

• Never coil excess refrigeration tubing

• The compressor oil rapidly absorbs moisture. Minimize the exposure of the refrigeration system by not

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.
