remove the motor support.

9. Remove isolation sheet

Twist off the screws connecting isola-

tation sheet and end plate of condens-

er and chassis, and then remove the

isolation sheet.

10. Remove 4-way valve

Unsolder, the pipeline between com-

pressor, condenser, gas and liquid valve,

and then remove the 4-way valve.

(note: release all refrigerant before
