Installing Refrigeration Lines
The Evaporator and Condensing units should be piped according to the following
piping schematic:
Piping Legend
1. The 3/8"ODS liquid service valve is located on the Condensing unit.
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,
