Condensate Piping

Do not run condensate piping into underground areas near sanitary or sewage lines where toxic
and corrosive gas can seep into the system. This creates a pathway for the flow of poisonous gas to
penetrate inhabited areas.
● Check to ensure that the condensate pipe discharges moisture properly. If connected incorrectly, it can
cause structural damage to indoor wall and ceiling surfaces and damage to furniture and carpeting.
● Avoid sloping the condensate pipe upward as it will impede drainage. Otherwise, moisture will settle back
into the unit and it may cause the water leakage when unit operation stops.
● Do not connect condensation drainage with sanitary or sewer lines or any other condensate pipe.
● When the main condensate pipe is connected with other indoor units, the connected position of each
indoor unit must be higher than the main pipe. The pipe size of the main condensate pipe must be large
enough according to the unit size and number of units.
● After performing condensate piping work and electrical wiring, check to ensure that water outflow is as
smooth as in the following procedure.
Perform condensate piping work and attach the insulation before attempting any refrigerant piping work.
1. The position of the condensate pipe connection is
shown at right.
2. Prepare PVC piping with 1-1/4 inches (32mm) outer diameter and an elbow piping joint with VP25.
3. Connecting Condensate Piping
NOTE:
Follow procedures b. and c. on the next page to install the factory supplied condensate hose and pipe
without adhesive.
a. Connect the factory-supplied condensate hose at the condensate pipe connection using
PVC adhesive. Clean the affected surfaces apply the adhesive and cure in accordance with
manufacturer's instructions.
b. Insert the condensate hose completely. If it is not inserted properly, or if it is twisted, water leakage
can occur.
