Airow direction adjustment
The airow path may be adjusted to distribute air independently from the left or right side of the discharge opening. Each of the
banks of louvers can be directed left, right, up, or down in order to achieve the most optimum airow positioning.
To adjust airow direction, grab the lever in the center of the louver bank and move it in the direction that you would like the air
to be directed. Please note that it is normal that airow may be stronger out of one side of the louvers than the other.
Fresh air and exhaust control
Your air conditioner has the ability to bring fresh air into the room or exhaust stale air out of the room. The control slide is found on
the upper part of the unit (see Figure 301).
TO BRING IN FRESH AIR – Move the lever to the Fresh Air position which allows outside air to enter the room. This is useful
in fall and spring as a means of bringing in fresh outside air when using FAN ONLY. It can also be used in the summer with the
compressor in the Cooling Mode if you wish.
TO EXHAUST INDOOR AIR – Move the lever to the Exhaust position. This will allow stale air to be expelled to the outside of
the dwelling. This is especially handy in the spring or fall when indoor air tends to get stale, or after a social gathering involving
smokers, or to remove cooking odors.
BEST PERFORMANCE – Move the lever to the Re-Circulate Position. This is the most efcient mode for cooling and heating.
