About the Controls on the Air Conditioner

Additional controls and important information.

Ventilation

The ventilation lever must be in the CLOSE position in order to maintain the
best cooling conditions.

When fresh air is necessary in the room, set the ventilation lever to the
OPEN position.
The damper is opened and room air is drawn out.

Air Direction

The direction of air can be controlled wherever you want to cool by adjusting the
horizontal louver and the vertical louver.

How to Secure the Drain Pipe

In humid weather, excess water may cause the BASE PAN to overflow. To drain the water, remove the DRAIN
CAP and secure the DRAIN PIPE to the rear hole of the BASE PAN. Press the drain pipe into the hole by pushing
down and away from the fins to avoid injury. (See Fig. 1)

Optional(CW3H02502C)

1. Remove the rubber plug and slide the chassis out
from the cabinet. (See Fig. 2)

2. Install the drain pan over the corner of the cabinet
where you removed the plug with 4 screws.
(See Fig. 3)

3. Connect the drain hose to the outlet located at the
bottom of the drain pan. You can purchase the drain
hose or tubing locally to satisfy your particular
needs. (Drain hose is not supplied). (See Fig. 3)

4. Select the most appropriate connection from among
the figures to the right (by considering the hole of the
unit) to fit drain pan to your own unit. (See Fig. 3)

5. Slide the chassis back into the cabinet. Reinstall the
cabinet screws. Secure the cabinet to chassis by
using screws. (See Fig. 4)

About the Controls on the Air Conditioner

Air Filter Cleaning

The air filter behind the front grille should be checked and cleaned at least once every 2
weeks or more often if necessary.

TO REMOVE:

1. Open the inlet grille upward by pulling out the bottom of the inlet grille or downward by
pulling out the top of the inlet grille.

2. Using the tab, pull up slightly on the filter to release it and pull it down or up.

3. Clean the filter with warm, soapy water below 40°C (104°F).

4. Rinse and gently shake the water from the filter and let it dry before replacing it.

CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will

clog it and reduce performance.

Care and Maintenance

TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.

• Do not use rechargeable
batteries. Such batteries
differ from standard dry cells in
shape, dimensions, and
performance.

• Remove the batteries from the
remote controller if the air
conditioner is not going to be
used for an extended length of
time.

• Keep the remote control away
from infants and small children
to prevent them from
accidentally swallowing the
batteries.

How to insert batteries

1. Remove the cover from the back of

the remote
controller.

2. Insert two AAA dry cell batteries.

• Be sure that the (+) and (-)
directions are correct.

• Be sure that both batteries are new.

3. Re-attach the cover.

WINDOW REQUIREMENTS

1. This unit is designed for installation in
standard double hung windows with actual
opening widths from 29" to 41".
The top and bottom window sashes must
open sufficiently to allow a clear vertical
opening of 18" from the bottom of the upper
sash to the window stool.

2. The stool offset (height between the stool
and sill) must be less than 1 1/4".

Installation

How to Install the Unit

1. To prevent vibration and noise, make sure the unit is installed securely and firmly

2. Install the unit where the sunlight does not shine directly on the unit.

3. The outside of the cabinet must extend outward for at least 30.5 cm(12") and there
should be no obstacles, such as a fence or wall, within 50.8 cm(20") from the back of
the cabinet because it will prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

CAUTION: All side louvers of the cabinet must remain exposed to the outside of the

structure.

4. Install the unit a little slanted so the back is slightly lower than the front
(about 12.7 mm(1/2")).
This will force condensed water to flow to the outside.

5. Install the unit with the bottom about 76.2~152.4 cm(30"~60") above the floor level.
