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.
DO NOT WRAP ENDS OF PIPING
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).
