ened; otherwise the fan motor lead may come to contact
with the propeller fan.	Fan motor
Attach the fan motor lead fixed rubber to the partition
board so that the projection is set at the refrigerating
cycle side.

•Be sure so that the rector body does not contact with the fan motor lead.

•Be sure to bundle the removed bundling band with the bundling band on the market.
