							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 (CW3H02502B)
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 (or 2) 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)

Care and Maintenance
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 under 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. TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
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.• Do not use
rechargeable batteries.
Such batteries 
differ from standard dry
cells in shape,
dimensions, and
performance.

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

radiation
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 12 (30.5cm) and there
should be no obstacles, such as a fence or
wall, within 20 (50.8cm) 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 
1/2(12.7mm)).
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30~60(76.2~152.4cm) above the floor level.
Window Requirements
NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
This unit is designed for installation in standard
double hung windows with actual opening widths
from 27 to 39 (68.6~99.1cm).
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
16 (40.6cm) from the bottom of the upper sash
to the window stool.
