switched off?

6. Is the circuit overloaded by other devices on

the same line?

7. Is the thermostat knob set too low comparing

to the temperature of indoor?

diameter large enough to carry the current?

B. WHEN AIR CONDITIONER DOES

NOT COOL AS IT SHOULD;

1. Is the operation switch set properly?

2. Is the thermostat control set properly to

provide the desired cooling?

3. Are there too many people than the usual

number in the room?

4. Is the air circulation restricted by drapes,

furniture, etc., or by an improper vane
setting?

5. Are the doors or windows open, or is there

an unusual heat source in the room?

cooling?

7. Is the air filter clean so that it will not obstruct

the air flow?

8. Have all the steps outlined in the Installation
