Application Recommendations:
1.
Piping should be in accordance with accepted industry standards.
2.
The condensate drain pipe should be sized adequately to ensure the condensate
drains properly. The bottom of the drain pan should be twice the distance of the internal static pressure
water column above the exit of the trap.
3.
When connecting suction and liquid connections make sure the coil is free from all foreign material. Make
sure all joints are tight and free of leakage.
4.
Greenheck does not supply compressor or condensing units, for further instruction on DX coil installation
