Design of the Condensate Pipe
1. Either the right rear or right side of the unit is suitable for affixing the condensate pipe.
2.
The drain pipe should maintain a downward sloping angle of 5~10° to avoid water
accumulation or improper drainage which could lead to equipment and/or property damage.
3. When connecting the drain pipe to the unit, avoid excessive force on the connection. The pipe
should be as close to the unit as possible.
4. Construct the drain pipe from material approved by the Authority Having Jurisdiction (AHJ).
Make a liquid tight connection between the drain hose and main drain with a clamp rather than
adhesive.
5. The diameter of the drain pipe should be greater than or equal to that of the refrigerant pipe.
(PVC pipe, outer diameter : 1 inch (25mm), wall thickness
≥
0.05 inches (1.5mm).
6. The drain pipe should be as short as possible and with at least a 0.6 degree slope to avoid
forming air pockets.
Installation of the Condensate Pipe
1. Use the supplied drain hose and clamp.
2. Insert the drain pipe into the opposite end of the drain hose and clamp securely (this clamp
supplied by installer). Do not use adhesive at this joint.
3. Insert the drain hose completely into the drain socket. Tighten the clamp to ensure a good
seal.
4. Wrap the attached foam wrap over the clamp and drain hose to insulate.
5. Confirm that adequate drainage is achieved after the condensate hose has been attached.
Test by pouring water into the drain pan from the air outlet.
