UNIT INSTALLATION

3.7 Drainage Piping
Installation Steps
After the unit is installed, ensure the unit is level. It must be placed horizontally to ensure it will function
properly.
When shipped out from the factory, both condensate outlets are blocked by rubber plugs. Remove both plugs
before installation. For condensate removal, attach a PVC pipe to the drain pan with termination in accordance
with local or state Plumbing/HVAC codes.
The indoor coil condensate drain ends with a threaded 3/4" (NPT) or 1-1/5" stub tube. A trap must be built for
proper condensate drainage and to prevent debris from drawing into the unit.
The condensate pipe should be installed with an inclining angle of 5~10° to facilitate condensate drainage.
When the inside of the unit is in a negative pressure status, a backwater elbow is required.
Requirements: A=B≥P/10+20(mm)
Note: P is the absolute pressure inside the unit. The unit of pressure is Pa. After the electrical installation is
completed, carry out testing of the drainage system.
