GENERAL:

1. All service work should be performed in a clean area.

the Driven Magnet Assembly.

3. An even, light coat of high vacuum silicone grease (Dow Corning or equiv.) should be applied to all seals or O-

Rings.

4. O-Rings with chamfers should always be installed with the chamfer up, away from the groove.

5. All assembly screws should be tightened evenly and in an alternating pattern.

6. Only Micropump factory authorized replacement parts should be used when servicing any Micropump products.

SPECIFIC:

1. Do not attempt to remove Driving Gear Shaft (2) from Pump Body (1). The Shaft (2) position is preset at the

factory. (If replacement of shaft is necessary, pump must be returned to the factory for repair.)

2. After installing the Suction Shoe (6), locate the Suction Shoe Spring (7) so that it holds the Suction Shoe in

tighten the Screw.

3. Engage drive pins on the Magnet Assembly (9) with Driving Gear (3). Gears and Magnet should rotate freely.
