Site Preparation and Installation<br />
Drain Line<br />
! CAUTION<br />
The drain line must not be trapped outside the unit, or water may back-up in drain pan.<br />
Drain is internally trapped.<br />
This line may contain boiling water. Use copper or other suitable material for the drain line.<br />
Sagging condensate drain lines may inadvertently create an external trap.<br />
A 3/4 in. (19.1 mm) female pipe thread (FPT) connection is provided for the evaporator coil condensate<br />
drain. This line also drains the humidifier, if applicable. The drain line must be located so it will not<br />
be exposed to freezing temperatures. The drain should be the full size of the drain connection.<br />
The evaporator drain pan includes a float switch to prevent unit operation if drain becomes blocked.<br />

These are external traps also, although<br />
unintentional. Lines must be rigid<br />
enough to not bow between supports.<br />
