Thermal Insulation of the Condensate Pipe
CAUTION
Seal properly and verify there is no water leakage from the joint of the condensate pipe.
Failure to do so may result in equipment and/or property damage.
1. The condensate pipe should keep a downward sloping angle of 5~10°, which can facilitate
drainage of the condensate water. The joints of the condensate pipe should be insulated
with insulation material to prevent condensation.
2. There is a condensate outlet on both the left and right sides of the unit. Once the proper
drain position is determined, the unused location should be sealed by a rubber plug. Be sure
to secure with a clamp and insulate completely to avoid condensate build-up.
3. The outlet on the right side of the unit is sealed by default.
