To properly clean and sanitize the pump for use with food products, it may be necessary to use chemical solutions. Many of the commonly used chemical solutions could cause severe injury to personnel if contacted. The hazard is especially severe for eyes, skin, or inhalation.

Prior to using any rotary pump for the rst time, disassemble and hand clean the pump. Clean all inner and outer surfaces to remove any dirt, grit or lm that may have accumulated during shipment and installation.

1. Do Not use carbon steel wool. Particles may break o and become embedded, causing rust development.

2. Do Not use water high in iron, salt or sulfur. Use distilled water if possible.;

3. Do Not allow cleaners or bactericides to remain on surface for over 15 minutes.

4. Rinse all parts and surfaces exposed to corrosive cleaning solutions completely with cold water.

5. Do Not allow tools or other metal items to lie on wet stainless steel.

6. Only use recommended cleaners. Alkaline dairy cleaners or bactericides should contain a wetting agent and polyphosphate to suit water hardness.

Loosen the set screws. Loosen the top and bottom bearing adjusting nuts. This will free rotation of the shafts.

Rotate the top shaft back and forth. Tighten the top bearing adjusting nut until a slight resistance to the top shaft is felt. Mark the position of the top bearing adjusting nut and back it on one-half turn.

Rotate the bottom shaft back and forth. Tighten the bottom bearing adjusting nut until a slight resistance to the bottom shaft is felt. Lock the bottom bearing adjusting nut set screw after adjusting.

Turn the top bearing adjusting nut so that the marks line up.

Lock the top bearing adjusting nut set screw after aligning marks.

If bearing adjustment has been performed and the shafts are still loose, replace the bearings.

Rotate the shafts back and forth 180o during bearing adjustment. Putting a crescent wrench on shaft squares will make turning of the shafts easier.
