1. Draining Oil

Drain oil by referring to Section 3.2.2 "Changing refrigerating oil."

2. Remove The Side Caps (One on Each Side) and The Discharge End Cover. (in case of

ZH9F, oil collector)

Receive remaining oil with a drain pan.

Be sure to mount guide bolts when removing the discharge end cover.

Furthermore, since continuous capacity control units have a pilot valve (as shown in Fig. 4-

2-2) inside, remove the discharge end cover with care paid not to bend this valve.

Be careful not to damage the oil filter with the discharge end cover.

Locate the first demister between the discharge end cover and cylinder cover, and remove it.
