Connect Drain Pipe - MrCool DIY E Star Series Installation & Owner's Manual

Step 7: Connect Drain Pipe
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. 4.5a as a guide, make sure
your drain pipe is run in a similar manner. The
other examples in Fig 4.5 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.
