How to Attach Drain Pan (Some Models)
How to Connect a Drain Hose
The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the
air) is drained to the outside.
In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed
from the air may cause some water to collect. To remove this excess water you can install the drain pan as
detailed below.
1. Take the drain pan which is located in the air discharge.
2. Remove the hole rubber from the base-pan (for some models).
3. Install the drain pan to the right corner of the cabinet with 4 (or 2)
screws.
4. 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).
A drain hole is provided at the rear of the air conditioner unit.
Select a drain method according to the following.
1. Remove the hole rubber from the base-pan. (for some models)
2. Connect a drain hose to the drain pipe as shown in Fig. 1.
3. Or connect a pipe elbow to the drain pipe, then connect a drain hose
to the pipe elbow as shown in Fig. 2.
Outdoor Coils
The coils on the outdoor side of the air conditioner should be checked
regularly. If they are clogged with dirt or soot they may be professionally
steam cleaned, a service available through a dealer.

Air Filter Cleaning
How to Attach Front Grille to Cabinet
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the
filter will build up and block the airflow. This reduces the cooling capacity and also causes an accumulation of
frost on the cooling coils.
1. Open the inlet grille upward by pulling out the bottom of the inlet grille.(a)
In another case, you can open the inlet grille downward by pulling out the top of the inlet grille.(b)
2. Remove the air filter from the front grille assembly by pulling the air filter up or down slightly.
3. Wash the filter using lukewarm water below 40 C (104 F).(c)
4. Gently shake the excess water from the filter completely. Replace the filter.
CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will clog it and
reduce performance.
:Mark ∆of inlet grille means opening direction.
NOTICE
1. Pull down front grille from the cabinet top.
2. Push front grille’s tips toward the cabinet in order to
insert front grille’s tabs into the cabinet.
3. Open the inlet grille.
4. Tighten the screw through the front grille into the
plate of the evaporator.
5. Close inlet grille.

Installation Steps
Hardware
Installation
Read completely, then follow step-by step.
•The appliance shall be installed in accordance with national wiring regulation.
•If a power plug isn't to be used, provide a circuit breaker between power source and the unit, as following
picture.
Select the Best Location
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. There should be no obstacle, such as a
fence or wall, within 50cm 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.
4. Install the unit a little obliquely outward not to leak the
condensed water into the room (about 10 ~ 15 mm or 1/4
bubble with level).
CAUTION: All side louvers of the cabinet must
remain exposed to the outside of the structure.
Remove the Air Conditioner From the Case
1. Remove the 2 shipping screws from the back of the
case.
2. Remove the 2 screws on each side of the case.
Keep these for later use.
3. Slide the air conditioner from the case by gripping
the base pan handle and pulling forward while
bracing the case.
4. Before installing the Air Conditioner back into the
case, remove the white styrofoam shipping block
from the compressor (Applicable for some models).

Install the Air Conditioner in the Case
1. Slide the air conditioner into the case.
Reinstall the 2 screws removed earlier on each
side of the case.
CAUTION: The power cord must be
connected to an independent circuit. The
green wire must be grounded.
2. Stuff the foam between the top of the unit and the
wall to prevent air and insects from getting into the
room.
3. Before installing the front grille, pull out the vent
control lever located above the unit control knobs,
as shown.
5. Attach the front grille to the case by inserting the
tabs on the grille into the slots on the front of the
case. Push the grille in until it snaps into place.
6. Lift the inlet grill and secure the front grille with a
screw. Lower the inlet grille into place.
When you detach the front grille
from the case, push the grille to
your right side and pull it toward
you.
Use the Reversible Inlet Grille
1. If you want to pull out the filter upward, open the inlet grille slightly.
Turn inside out the front grille.
Disassemble the inlet grille from the front grille with separating the hinged part
by inserting a "—" type screw-driver tip.
Rotate the inlet grille 180 degrees and insert the hooks into the lower holes of
front grille.
Then, insert the filter
2. If you want to pull out the filter downward, use the reversible inlet grille without
change.(The grille is already assembled for that way.)

Common Problems and Solutions
Common
Issues
Troubleshooting Tips
Save time and money! Review the chart below first and
you may not need to call for service.
Normal Operation
•You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy
days or when the humidity is high. This design feature helps remove moisture and improve efficiency.
•You may hear the thermostat click when the compressor cycles on and off.
•Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from
the outdoor side of the unit.
•The fan may run even when the compressor does not.
Abnormal Operation
Problem Possible Causes What To Do
■The air conditioner is unplugged.
■The fuse is blown/circuit breaker is
tripped.
■Power failure.
■Airflow is restricted.
■The thermostat may not be set
high enough.
■ TEMP Control set too higher
number.
■The air filter is dirty.
■The room may have been hot.
■Cold air is escaping.
■Cooling coils have iced up.
■Ice blocks the air flow and stops
the air conditioner from cooling the
room.
•Make sure the air conditioner plug is pushed
completely into the outlet.
•Check the house fuse/circuit breaker box and
replace the fuse or reset the breaker.
• If power failure occurs, push power button to OFF.
When power is restored, wait 3 minutes to restart
the air conditioner to prevent tripping of the
compressor overload.
•Make sure there are no curtains, blinds, or
furniture blocking the front of the air conditioner.
•Turn the knob to a higher setting. The highest
setting provides maximum cooling.
•Set the TEMP control to a lower number.
•Clean the filter at least every 2 weeks.
See the operating instructions section.
•When the air conditioner is first turned on you
need to allow time for the room to cool down.
•Check for open furnace floor registers and cold
air returns.
•Set the air conditioner's vent to the closed
position.
•See Air Conditioner Freezing Up below.
•Set the mode control at MED fan or high cool
with the thermostat at 1or 2(Left side).
•Set the mode control at HIGH fan or high cool
with the high temperature.
