OFF(O) 

- Turns air conditioner off.

HIGH FAN

- High speed fan operation without

cooling.

LOW FAN

- Low speed fan operation without

cooling.

HIGH COOL - Cooling with high speed fan operation.
LOW COOL  - Cooling with low speed fan operation.

This automatically controls the temperature of the
indoor air.
Turn the knob so that arrow points to the larger
marks for greater cooling. Point the arrow to the
smaller marks for more moderate cooling.
(i.e. the higher the number, the greater the cooling)

CAUTION : After switching the air conditioner from COOL to OFF(O) or FAN, wait at least 3 minutes before

switching it back to COOL.

1. When servicing, set the ROTARY SWITCH to OFF(O)

and unplug the power cord.

2. Oberve the original lead dress.

If a short circuit is found, replace all parts which have
been overheated or damaged by the short circuit.

3. After servicing, make an insulation resistance test to

prevent the customer from being exposed to shock
hazards.

1. Unplug the power cord and connect a jumper

between 2 pins (black and white).

2. The grounding conductor (green or green and

yellow) is to be open.

3. Measure the resistance value with an ohm meter

between the jumpered lead and each exposed
metallic part on the equipment at all position
(except OFF(O)) of the ROTARY SWITCH.

4. The value should be over 1M

Ω

.

This air conditioner is designed with a button-down

chassis so that it can be installed simply in a
window.

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 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 conditioner.

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

lower than the front (about 1/2"). This will force
condensed water to the outside.

5. Install the unit with the bottom about 30"

¡›

60"

above the floor level.

The setting conditions must be checked prior to
initial starting.
The undermentioned items are especially
inportant checking points when the installation is
finished.

1. Grounding wire (Green of Green Yellow) is

provided in the power cord. The green wire must
be grounded.

2. Connect to a single-outlet 15AMP circuit.
3. To avoid vibration or noise, make sure the air

conditioner is installed securely.

4. Avoid placing furniture or dreperies in front of the

air inlet and outlet.

The air conditioner must be installed level or titled
slightly to the outside for proper water drainage.
On exceptionally not and humid days the air
conditioner may drain condensation through
overflow. If the air donditioner is used in hot and
a high humidity zone, dxchange the
