4）When connecting three-way pipes, the two-way straight pipes must be laid on the same
slope, as shown in the following figures.
5）The condensate water pipe cannot be tied with the refrigerant pipe.
6）A ventilation hole must be provided on the top of the drain pipe to ensure smoother
discharge of condensate water.
7）After pipes are connected, perform a test with some water and another test with full water in
the pipe to check whether drainage is smooth and whether water leakage exists in the pipe
system.
8）Equip a steel casing for all pipes which are led through the wall or floor. Pipe bonding joints
cannot be placed inside the sleeve. The steel casing must be parallel with the bottom of the floor
or wall. There must be a height drop of 20 mm from the ground when the pipe is lead through the
floor. The sleeve cannot affect the inclination degree of the pipe. Fill the gap between the pipe and
the sleeve with flexible and non-flammable materials. The sleeve cannot be used as a support
point of the pipe.
9）Bond the insulation material joints with special glue and then wrap them with plastic
adhesive tape. The width of the adhesive tape must be 5cm or more to prevent dewing.
10）When connecting the drain pipe to that of the IDU, fix the pipes with the bands provided
upon delivery instead of using the glue to facilitate further maintenance.
11）When connecting the drain pipe branches to the main pipe, lead through from the above
part of the main pipe.
12）If the air volume of the IDUs is high and outdoor air resorption may be caused by negative
suction pressure, provide a u-type drain trap at the water outlet side of each IDU, as shown in the
following figure.
