After flared the pipe, the opening part must be seal by end cover or adhesive tape to avoid duct or
exogenous impurity come into the pipe.
5.2.7 Drill holes if the pipes need to pass the wall.
5.2.8 According to the field condition to bend the pipes so that it can pass the wall smoothly.
5.2.9 Bind and wrap the wire together with the insulated pipe if necessary.
5.2.10
Set the wall conduit
5.2.11 Set the supporter for the pipe.
5.2.12 Locate the pipe and fix it by supporter
¾
For horizontal refrigerant pipe, the distance between supporters should not be exceed 1m.
¾
For vertical refrigerant pipe, the distance between supporters should not be exceed 1.5m.
5.2.13 Connect the pipe to indoor unit and outdoor unit by using two spanners.
¾
Be sure to use two spanners and proper torque to fasten the nut, too large torque will damage the
bellmouthing, and too small torque may cause leakage. Refer the following table for different pipe
connection.

6. Drainage pipe installation
Install the drainage pipe as shown below and take measures against condensation. Improperly installation
could lead to leakage and eventually wet furniture and belongings.
6.1 Installation principle
¾
Ensure at least 1/100 slope of the drainage pipe
¾
Adopt suitable pipe diameter
¾
Adopt nearby condensate water discharge
6.2 Key points of drainage water pipe installation
6.2.1 Considering the pipeline route and elevation
¾
Before installing condensate water pipeline, determine its route and elevation to avoid intersection with
other pipelines and ensure slope is straight.
