GENERAL OPERATING INSTRUCTIONS
___________________________________________________________________________________________
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.
Airflow Around Unit
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 thermostat 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 grill 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 off and on 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 install, remove the unit chassis from the outercase.
Insert the condensate drain cup through the recessed
½” hole on the back center of the outercase. 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 outercase. The unit basepan
overflow hole will be positioned directly above the
drain cup and will catch any water that might run out.
