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.
Initial Start-Up and Cooling
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 below).
To install, remove the unit chassis from the outer case. Insert the condensate drain cup through the recessed ½” hole on the right side bottom flange 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.
Select the highest fan speed and set temperature control to its coldest position. When the desired temperature is reached, slowly move the temperature control toward a warmer setting until the compressor shuts off. The thermo- stat will then cycle the compressor on and off to maintain this selected temperature. Adjust the fan speed for desired air circulation.

Changing Airflow Direction Baffles
Airflow on unit may be diverted left or right from center by baffles. Upward and downward air discharge is provided by tilting louvers. Adjust baffles and tilt louvers for desired airflow pattern.
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.

Emergency heat switch overrides heat pump (compressor) and starts auxiliary electrical heater. When switch is ON, heat pump is locked out.
•Use emergency switch only when heat pump fails to provide adequate heat. Cause of heat pump malfunc- tion should be determined by authorized servicer. Cost of operating unit will increase when emergency heat switch is engaged.
To access and engage emergency switch:
1.Remove front grille, air filter, and plastic front, as de- scribed in Installation Instructions.
2.Remove basepan clip.
3.Slide chassis out of case about two inches.
4.Locate access hole for emergency switch above label on right front of control box.
5.To start emergency heat, insert flathead screwdriver into slot and turn counterclockwise until
6.Return chassis to case.
7.Replace basepan clip, plastic front, air filter, and front grille.
