Page 1-5. Paragraph 1-6 is superseded as follows:
1-6. Differences in Models. The differences in models are that the Model 844-5-V-100AL has a pop-up type
differential pressure indicator and ModeIs V-1520-ANZ and FS-100VM have a differential pressure indicating gage.

Page 1-5. Paragraph 1-7b (5.1). Change heading to read:
(5.1) Differential pressure indicator (Models V-1520-ANZ and FS-100VM).
Page 2-1. Paragraph 2-2b (5) is superseded as follows:
(5) Check differential indicator periodically. Change filter elements (para 3-5) immediately if the red button
on the indicator is in a raised position (Model 844-5-V-100AL) or the gage readings are in any portion of the red
band (Models V-1520-ANZ and FS-100VM).
Page 2-2. Paragraph 2-4a (3), add as follows:
(3) For Model V-1520-ANZ and FS-100VM filter-separators, check the pressure differential gage
periodically to be sure the pressure reading is below the red band on the gage.
Page 2-2. Paragraph 2-4b (5), add as follows:
(5) For Model V-1520-ANZ and FS-100VM filter-separators, check the pressure differential gage
periodically to be sure the pressure reading is below the red band on the gage.
Page 2-2. Paragraph 2-4c (4), add as follows:
(4) For Model V-1520-ANZ and FS-100VM filter-separators, check the pressure differential gage
periodically to be sure the pressure reading is below the red band on the gage.
Page 2-2. Paragraph 2-4d (3), add as follows:
(3) For Model V-1520-ANZ and FS-100VM filter-separators, check the pressure differential gage
periodically to be sure the pressure reading is below the red band on the gage.
Page 2-2. Paragraph 2-4e (3), add as follows:
(3) For Model V-1520-ANZ and FS-100VM filter-separators, check the pressure differential gage
periodically to be sure the pressure reading is below the red band on the gage.
