Temperature Setting

This button can automatically control the temperature

of the room. The temperature can be set within a range of

60°F to 86°F by 1°F.

Select the lower number for lower temperature of the room.

Energy Saver

The fan stops when the compressor stops cooling.

Approximately every 3 minutes the fan will turn on and check the room air to determine if cooling is needed.

Fan/Cool/Dry

Everytime you push this button, it will toggle between COOL, FAN, and DRY.

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 from being exposed 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 position [except Off] of the ROTARY SWITCH.

4.The value should be over 1 M.
