2.If required, install lifting eyes on oil separator man- hole cover, see Figure 5-6.

WARNING

Use appropriate lifting devices and additional personnel when lifting heavy components. Ensure lifting devices are capable of lifting the weight of the component. Use lifting points (i.e. bolt holes designated for lifting eye bolts) that are provided on the component. Failure to comply may result in

serious injury.

WARNING

Avoid skin contact with any condensate or oil. Wear rubber gloves and a face shield when working with condensate or oil. Failure to comply may result in serious injury or death.

NOTE

3.Secure appropriate lifting device to oil separator manhole cover.

4.Remove all bolts except top four bolts securing oil separator manhole cover to oil separator vessel.

5.Adjust lifting device as needed to hold weight of oil separator manhole cover.

6.Remove remaining four bolts and oil separator manhole cover from oil separator vessel.

7.Remove nuts, ﬂat washer and cover plate securing coalescing oil ﬁlter to hold-down rod.

8.With assistance of second person, remove coalesc- ing ﬁlter from oil separator vessel.

9.Repeat steps 7 and 8 to remove additional coalesc- ing ﬁlters, as required.

For coalescing oil ﬁlters (11-7/8 in. O.D.), a tubing (3/4 in. O.D. x 6 ft. long ) can be used to aid in removal and installation of the element.

REMOVAL

1.Isolate the compressor unit, see Compressor Unit Isolation procedure.

INSTALLATION

10.Install tubing over hold-down rod. Position tubing as far back as possible.

11.With assistance of second person, position coalesc- ing element over tubing and through hole of cen- tering strap.

12.Push coalescing ﬁlter into vessel until fully seated
