1. To prevent vibration and noise, make sure the unit

in 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 10" and there should be no obstacles, such
as a fence or wall, within 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 condditioner.

4. Install the unit a little slanted so the back is slightly

lower than the front (about

"). This will force con-

densed water to the outside.

5. Install the unit with the bottom about 30"~60" above

the floor level.

1. Remove the screws which fasten the cabinet 

at both sides and at the back.

2. Slide the unit from the cabinet by gripping the 

base pan handle and pulling forward while 

bracing the cabinet.

3. Remove EPS Material.

4. Slide the unit into the cabinet.

CAUTION: For security purpose, reinstall screw at

cabinet's sides.

5. Attach the front grille to the cabinet by 

inserting the tabs on the grille into the tabs on the
fornt of the cabinet. Push the grille in until it snaps
into place.

6. Lift the inlet grille and secure it with a screw

Check voltage. See the limits on the preceding
page. If not within limits, call an electrician.

Check the wire connections, if loose, repair or
replace the terminal. If wires are off, refer to wiring
diagram for identification, and replace. Check wire
locations. If not per wiring diagram, correct.

Check for continuity, refer to the wiring diagram
for terminal identification. Replace the switch if
circuit is open.

Check the position of knob If not at the coldest
setting, advance the knob to this setting and
restart unit.
Check continuity of the thermostat. Replace
thermostat if circuit is open.

Check the capacitor.
Replace if not within ±10% of manufacturers
rating. Replace if shorted, open, or damaged.

Check the compressor for open circuit or
ground. If open or grounded, replace the
compressor.

Check the compressor overload, if externally
mounted. Replace if open. (If the compressor
temperature is high, remove the overload, cool it,
and retest.)

Check the voltage. See the limits on the preced-
ing page. If not within limits, call an electrician.

Check overload, if externally mounted.
Replace if open. (If the compressor temperature
is high, remove the overload, cool, and retest.)

If not running, determine the cause. Replace if
required.

Remove the cabinet. Inspect the interior surface
of the condenser; if restricted, clean carefully
with a vacuum cleaner (do not damage fins) or
brush. Clean the interior base before
reassembling.

If condenser fins are closed over a large area
on the coil surface, head pressures will increase,
causing the compressor to cycle. Straighten the
fins or replace the coil.

Test capacitor.

Check the terminals. If loose, repair or replace.
