1.3 LOCATIONS OF CONTROLS
1.4 SAFETY PRECAUTIONS
1. When servicing, turn the unit 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 circuit.
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 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 each working status.
4. The value should be over 1 MΩ.

The fan stops when the compressor stops cooling.
• Approximately every 3 minutes the fan will turn on and sample the room air to determine if more cooling is needed.
TEMPERATURE SETTING
1
• These buttons control the temperature of the room.
The temperature can be set within a range of 60°F to 86°F, in increments of 1°F.
ON/OFF TIMER
4
ON–When the air conditioner is off, it can be set to automatically
come on in 1 to 12 hours from its previous setting. Each touch will increase the timer by 1 hour. OFF–When the air conditioner is on, it can be set to automatically turn off in 1 to 12 hours. Each touch will increase the timer by 1 hour. After the timer has been on for 30 minutes, the temperature will automatically rise 2°F, and after another 30 minutes, it will automatically rise 2°F again. The temperature will then stay the same until the timer goes OFF.
To cancel the timer, press the TIMER pad until the display time disappears.
