3. Inspect the mounting hardware for cracks, breaks and damaged threads. Replace any defective
parts.
c. Installation.
1. Refer to Fig. 17 and install the pump base plate.
2. Install the circulating pump and pump coupling. (Para. 33).
3. Install the circulating pump motor (Para. 34).
To align circulating pump to circulating pump motor, the center line height of both shafts must be the
same. The coupling should be parallel when aligned on the circulating pump shaft and the circulating
pump motor shaft with no more than .015 inches offset. This would be the maximum parallel offset
allowed. The angular offset must not be more than 1 degree.
