5. Attach a 5/8” (16mm) I.D. reinforced hose to the hose barb and secure with stainless-steel hose clamps.
6. Install the condensate drain hose downhill from the unit and aft to a sump. The hose should have a trap.
7. Two drain fittings may be used and the hoses teed together provided there is a minimum 2" (51mm) drop from the
bottom of the base pan to the tee connection.

RAP
Consideration should be given to installing a trap in the condensate drain line(s) so that normal discharge of condensate can fill
the trap and prevent the ingress of carbon monoxide (CO) or other potentially harmful vapors.

For greater flexibility in connecting to your ductwork, you can install the blower with either a horizontal or vertical supply-air
discharge. Rotate the blower to allow the most direct flow of air to the supply-air grille.

ISCHARGE
For vertical discharge you must rotate the blower. Follow the steps below:
1. Remove wire tie holding blower wire harness to base pan and/or adjacent harness.
2. Remove and save the 7 screws holding the blower plate to the evaporator shroud. Remove 2 screws holding blower to
drain pan.
3. Rotate the blower 90 degrees so the discharge is in the vertical position and aimed upward, then reinstall the screws to
hold the blower plate to the evaporator shroud. (On some systems you may need to use the access hole in the base
pan and a long screwdriver to reach one of the screws.)
4. Use mounting bracket supplied with unit to mount blower to drain pan.
5. Make sure the power wire is repositioned so it will not catch on anything during or after installation.
The vertical rotation is complete.
WARNING
Do not terminate condensate drain line within three feet of any outlet of engine or generator exhaust systems, nor in a
compartment housing an engine or generator, nor in a bilge, unless the drain is connected properly to a sealed
condensate or shower sump pump.
Failure to comply may allow bilge or engine room vapors to mix with the air conditioner’s return air and contaminate
living areas which may result in injury or death.
NOTE
The empty screw holes have no effect on system performance.
