Power transformer (TR1) ................. Indoor unit
• Primary 230-208 V ; Measure the resistance between two WHT lead wire terminals
• Secondary 10.6 V ; Measure the resistance between two BRN lead wires.
Refer to "2. (3) (A) Other component specifications".

Power transformer (TR) ................. Outdoor unit
• Primary 230-208 V ; Measure the resistance between two WHT lead wire terminals
• Secondary 19 V
Refer to "2. (3) (B) Other component specifications".

Indoor fan motor (FMI) ............... Indoor unit
• Measure the resistance between each terminal of the socket connected to the
indoor fan motor.
Refer to "2. (2) (A) Major component specifications".

Outdoor fan motor (FMO) ........... Outdoor unit
• Measure the resistance in the same manner as explained above 2.
Refer to "2. (2) (B) Major component specifications".

Motor capacitor ............ Both in indoor and outdoor unit
• Remove the lead wires from the
capacitor terminals, and then place a
probe on the capacitor terminals as
shown in Fig. 18. Observe the deflec-
tion of the pointer, setting the resis-
tance measuring range of the multim-
eter to the maximum value.
• The capacitor is "good" if the pointer
bounces to a great extent and then
gradually returns to its original posi-
tion.
NOTE
The range of deflection and the deflection
time differ according to the capacity of the
capacitor.
