lessen the chance that service will be needed.
ITEMS IN INSTALLATION HARDWARE
You may not need all parts in the kit. Discard unused
parts
1. Identify the existing wall sleeve before installing the
unit from the listed below.
All wall sleeves used to mount the new Air
Conditioner must be in sound structural condition and
have a rear grille that securely attaches to sleeve, or
rear flange that serves as a stop for the Air
Conditioner,
2. Remove old air conditioner from existing wall
sleeve.
3. Clean the interior of an existing sleeve.
(Do not disturb seals.)
4. Wall sleeve must be securely fastened in wall
before installing the air conditioner. Use the nails or
screws through sleeve into wall, if needed. Repaint
sleeve if needed.
5. Prepare the wall sleeve for installation of the unit. If
you plan to use your existing wall sleeve, and it is
not LGE, use procedure B or C below.
6. Install new unit into wall sleeve.
When installation is completed, replacement unit
MUST have a rearward slope as shown. To achieve
1/4" slope, remove the backing from the 11-13/16"
shim strips and attach them as shown below in Fig. 3.
Place the higher portion of shim to the front of the rib
on base of wall sleeve.

How to Install
We strongly recommend the removal of the old wall
sleeve and the installation of a new HCI Wall Sleeve.
If you decide to keep the existing wall sleeve, you have
to redirect the louvers at the back of the wall sleeve illus-
tration. The use of pliers is recommended. If you DO
NOT redirect, you run the risk of poor performance or
product failure. This is not covered under the terms of the
Heat Controller warranty.

MODE
- Push this button to shift mode of operation from COOL → ENERGY SAVER → FAN → Heat.
- COOL:
•Fan runs continually for normal cooling operation.
- ENERGY SAVER:
•The fan stops when the compressor stops cooling. Approximately every 3 minutes the fan will turn on
and the unit will check the room air temperature to determine if cooling is needed.
- FAN:
•Fan-only operation.
- HEAT:
•Fan runs continually for normal heating operation.
When the air conditioner has been performed its cooling or
heating operation and is turned off or set to the fan posi-
tion, wait at least 3 minutes before resetting to the cooling
operation again.
A slight heat odor may come from the unit when
first switching to HEAT after the cooling season is
over. This odor, caused by fine dust particles on
the heater, will disappear quickly. This is harmless.

tical louvers.
• HORIZONTAL AIR-DIRECTION CONTROL
The horizontal air direction is adjusted by moving the vertical louver.
The lever for the vertical louver is located in the right and left side of the
air discharge.
•VERTICAL AIR-DIRECTION CONTROL
The vertical air direction is adjusted by moving the horizontal louver.
