Notes:
1. Single refrigerant circuit shown for clarity, for XDM400 units refrigerant connections are typical.
2. The bottom of the condenser coil cannot be more than 15' (4.6m) below the elevation of the EEVs inside the indoor unit.
3. 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.
4. Pitch horizontal hot gas piping at a minimum of ½ inch per 10 feet (42mm per 10m) so that gravity will aid in moving oil in the direction of the refrigeration flow.
5. All indoor and outdoor field refrigerant piping must be insulated, ½ inch minimum. All outdoor insulation must be UV and ozone resistant.
6. Consult factory for any exceptions to the above guidelines.
