DRAIN HOSE MUST BE ON BOTTOM
Make sure that the drain hose is at the bottom of the bundle. Putting the drain hose at the top of the bundle
can cause the drain pan to overflow, which can lead to fire or water damage.
When wrapping the bundle, keep the ends of the piping unwrapped. You need to access them to test for
leaks at the end of the installation process (refer to Electrical Checks and Leak Checks section of this
manual).

cable as shown in the figure(Not applicable for some
locations in North America ).
Using insulation tape, wrap the refrigerant pipes,
signal wire and drain hose tightly together.
Double-check that all items are bundled.
Using adhesive vinyl tape, attach the drain hose to
the underside of the refrigerant pipes.
