Notes:
1. The outlet of the receiver must be higher than the elevation of the EEV inside the indoor unit.
2. For proper pump function, a minimum elevation difference of 60 inch (1524 mm) must be maintained between the bottom of condenser coil to the bottom of EconoPhase unit.
3. The maximum equivalent piping between the Liebert MC Condenser and Econophase unit is 25 ft (7.6 m).
4. Unit must be trapped at bottom of riser with any rise over 5 feet (1.5m) high. If rise exceeds 25 feet (7.5m), then a trap is required in 20 foot (6.1m) increments or evenly divided.
5. Pitch horizontal hot gas piping at a minimum of 1/2" per 10 feet (42 mm per 10m) so that gravity will aid in moving oil in the direction of the refrigeration flow.
6. Unit piping entrance varies by unit and may be through the top of the unit.
7. All indoor and outdoor field refrigerant piping must be insulated, ½ inch minimum. All outdoor insulation must be UV and ozone resistant.
1-3/8 inch minimum diameter Liquid line.
DO NOT TRAP LINE! Slope 2 inch per
10 ft (167mm per 10 meter) down
towards EconoPhase unit.
Single Circuit system shown for clarity.
