GeneralOperatingInstructions

While operation of all units is similar, controls vary slightly from model to model. Operating Controls section shows control panel of unit purchased and gives detailed information about operation of controls.

To install, remove the unit chassis from the outer case. Insert the condensate drain cup through the recessed ½” hole on the back center of the outer case. Once inserted, place a ½” diameter hose or tube on the drain cup bottom spout. The hose allows you to route where you want the excess water to go. Reinsert the unit chassis into the outer case. The unit basepan overflow hole will be positioned directly above the drain cup and will catch any water that might run out.

Airflow Around Unit

Check the indoor grille and outdoor louvers for obstructions to airflow. do not block the airflow to and from the unit. If air is obstructed and/or deflected back into the unit, the air conditioner’s compressor may cycle on and off rapidly. This could damage your unit.

Drain Cup Installation and Use

Your air conditioner uses a system where the water removed from the indoor air (condensate) is channeled to the outdoor side of the unit. The outdoor fan blade has a “slinger” ring attached to it that dips into the water and slings the water onto the outdoor coil surface. This is the sound of water you hear during normal operation. The water quickly evaporates on this warm surface and improves the efficiency of your air conditioner. In normal conditions the unit can evaporate the water as fast as it is removed from the indoor air.

However, in very humid conditions excess amounts of water may drip off the unit chassis. If this proves to be a problem, install the condensate drain cup included with the unit to route excess water where it would not be a problem (see illustration).

To access and engage emergency switch:

• Unplug unit.

1.Remove front grille, air filter, and plastic front, as described in Installation Instructions.

2.Slide chassis out of case about two inches.

3.Locate access hole for emergency switch above label on right front of control box.

4.Remove control panel for access.

5.Remove outdoor thermostat from control box and locate "flat head" adjustment screw on back of thermostat.

6.To start emergency heat, insert flathead screwdriver into slot and turn counterclockwise until switch-stop is reached.

7.Return chassis to case.

8.Re-install lthermostat and mount control panel door.

9.Replace plastic front, air filter, and front

grille.
