-1. Measurement of Insulation

Resistance

The insulation is in good condition if the resistance

exceeds 2M

.

6

-1-1. Power Supply Wires

Clamp the grounding terminal of the power plug with a

lead clip of the insulation resistance tester and

measure the resistance by placing a probe on 

both

the two power terminals. (Fig. 1)

Then, also measure the resistance between the

grounding and other power terminals. (Fig. 1)

6

-1-2. Indoor Unit

Clamp a metallic part of the unit with the lead clip of

the insulation resistance tester and measure the

resistance by placing a probe on each terminal screw

where power supply lines are connected on the

terminal plate. (Fig. 2)

6

-1-3. Outdoor Unit

Clamp an aluminum plate fin or copper tube with the

lead clip of the insulation resistance tester and

measure the resistance by placing a probe on each

terminal screw on the terminal plate. (Fig. 2)

Note that the ground line terminal should be skipped

for the check.

6

-1-4. Measurement of Insulation

Resistance for Electrical Parts

Disconnect the lead wires of the desired electric part

from terminal plate, capacitor, etc. Similarly disconnect

the connector. Then measure the insulation resistance.

(Figs. 3 and 4)

Refer to Electric Wiring Diagram.

If the probe cannot enter the poles because the hole is

too narrow then use a probe with a thinner pin.
