    2.3 Receiving the mixer Figure 1: Mixer casing tag - English Figure 2: Mixer casing tag - metric Figure 3: Bearing frame tag 2.3 Receiving the mixer Inspect the mixer as soon as it is received. Carefully check that everything is in good order. Make notes of damaged or missing items on the receipt and freight bill.

  • Page 13: Handling

    2.3 Receiving the mixer Long Term: (More than 6 months): Requires special precautions. Preservative treatment of bearings and machined surfaces will be re- quired. Rotate shaft several times every 3 months. Driver and coupling manufacturers should be contact- ed for long term storage procedures. NOTICE: For pumps or back pull-outs supplied with cartridge mechanical seals, the centering tabs must be in place and tightened, and the set screw collar loosened.

    3.5 Measurement Check setting of indicators by rotating coupling half X to ensure indicators stay in contact with cou- pling half Y but do not bottom out. Adjust indicators accordingly. 3.5 Measurement To ensure accuracy of indicator readings, always rotate both coupling halves together so indicators contact the same point on coupling half Y.

  • Page 19: Parallel Alignment

    3.5 Measurement Negative Reading - The coupling halves are further apart on the right side than the left. Correct by either sliding the shaft end of the driver to the left or the other end to the right. Positive Reading - The coupling halves are closer together on the right side than the left. Correct by either sliding the shaft end of the driver to the right or the other end to the left, shown below.

  • Page 20: Complete Alignment

    3.5 Measurement NOTICE: Equal amounts of shims must be added to or removed from each driver foot. Otherwise the vertical angular alignment will be affected. Repeat steps 1 through 3 until indicator P reads within .05 mm (.002 in.) or less when hot, or per Table 2: Cold Setting of Parallel Vertical Alignment on page 15 when cold.

  • Page 21: Grout Baseplate

    3.6 Grout baseplate Make corrections as outlined previously. Recheck both vertical and horizontal readings to ensure adjustment of one did not disturb the other. Correct as necessary. NOTICE: With experience, the installer will understand the interaction between angular and parallel and will make corrections appropriately.
