1.3 LOCATIONS OF CONTROLS
1.4 SAFETY PRECAUTIONS
1. When servicing, set the ROTARY SWITCH to
Off and unplug the power cord.
2. Observe the original lead dress.
If a short circuit is found, replace all parts which
have been overheated or damaged by the short cir-
cuit.
3. After servicing, make an insulation resistance test
to prevent the customer's exposure to shock
hazards.
1.5
INSULATION RESISTANCE TEST
1. Unplug the power cord and connect a jumper
between 2 pins (black and white).
2. The grounding conductor (green or green and yel-
low) 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 positions
[except Off] of the ROTARY SWITCH.
4. The value should be over 1 MΩ.
CAUTION : After switching the air conditioner from Cool to Off or Fan, wait at least 3 minutes before switching it
back to Cool.
Off
—
Turns air conditioner off.
High Fan
—
High speed fan operation without cooling.
Low Fan
—

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 the 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)
