Installing Refrigeration Lines
The Evaporator and Condensing units should be piped according to the following
piping schematic:
Piping Legend
1. Liquid connection location.
2. Hermetic liquid line filter drier (shipped loose). Install with the directional flow
arrow as shown.
3. Liquid line sight glass with moisture indicator (shipped loose).
4. Liquid line refrigeration piping in accordance with Line Sizing Chart.
5. Factory installed liquid line solenoid valve (normally closed) (Dual
Power/Valve Control configurations only).
6. Factory installed thermostatic expansion valve. Bulb must be attached to a
horizontal run of the suction line after brazing the field suction connection, and
insulated with the supplied cork tape.
7. Factory installed ¼” evaporator suction access valve.
8. Insulated suction line refrigeration piping (refer to Line Sizing Chart below).
9. Suction connection location.
10.
Condensing unit ¼” liquid access port located on the liquid Rotolock valve
11. Conde nsing unit ¼” suction access port located on the suction Rotolock valve.
12. Water line inlet connection location.
13. Water line outlet connection location.
Line Sizing Chart
Refer to the Line Sizing Chart below for selecting the appropriate tubing size for
the length of the piping run. Note that the recommended line size may not match
the connection ports on the Condensing unit and the Evaporator. Refrigeration
grade fittings must be supplied by the installing technician to make the necessary
transitions. Transitions should be made as close to the unit as possible.
Suction line routing must be designed to ensure oil return to the Condensing unit.
