c. Attach the factory-supplied hose clamp to the vinyl tape (white) attached to the condensate hose.
The hose clamp shall be 13/16 inch (20mm) away from the end face of the condensate hose. Then
tighten the hose clamp to make sure that it is approximately 1-1/8 inches (28mm) in length from the
screw to the edge of the hose clamp as shown in the figure below.

● Make sure to use the factory-supplied condensate hose and hose clamp. Other makes are more
susceptible to moisture leakage.
● Do not bend or twist the factory-supplied condensate hose. Sealing properties of the hose can be
compromised.
● Do not apply an excessive force to condensate pipe connections. They can be easily damaged.
4. On-site Condensate Piping Work
a. Connect the factory-supplied condensate hose to the condensate pipe connection using the polyvinyl
chloride adhesive.
b. When cleaning the connection surface, applying the adhesive, inserting, retaining and curing the
condensate pipe, refer to information given by the adhesive manufacturer.
c. Install the support parts at an interval of 3.3 ft to 4.9 ft (1m to 1.5m) in order not to bend the
condensate pipe.
d. Install condensate piping with a downward slope of 1/25 to 1/100 as shown below.
e. Install the condensate hose horizontally or slightly on
an upward slope to prevent air pockets from forming
inside it. If air pockets form, moisture will settle back
into the unit, which could result in undesired sluicing,
bubbling noises and spillover into the room after unit
operation has stopped.
f. Raising Condensate Piping
In case of raising the condensate pipe, install it according to the dimension shown in the figure
below. The total condensate piping length of a+b+c shall be within 43-5/16 inches (1,100mm).
