In this step you will connect the drain hose extension to
the drain hose exiting from the indoor unit that is within
the piping bundle you wrapped in the previous steps.
1. Securely connect the drain hose extension to the
drain piping from the indoor unit.
2. Using example Fig. 6.3a as a guide, make sure your
drain pipe is run in a similar manner. The other
examples in Fig 6.3 represent things you should
avoid when installing your drain pipe.
3. Remove the air filter from the indoor unit and pour a
small amount of water into the drain pan to ensure
that the water exits the bottom of the unit and flows
through the drain and drain pipe smoothly.
