PREPARATION FOR START-UP
When installing in a potentially explosive
environment, please ensure that the motor
is properly certified.
CHECKING ROTATION
l
! CAUTION
Serious damage may result if pump is run in the
wrong rotation.
1. Lock out power to driver.
s
! WARNING
Lock out driver power to prevent accidental
start-up and physical injury.
2. Make sure coupling hubs are securely fastened to
the shafts and the coupling spacer has been
removed.
NOTE: Pump is shipped with coupling spacer
removed.
3. Unlock driver power.
4. Make sure everyone is clear. Jog driver just long
enough to determine direction of rotation. Rotation
must correspond to arrow on bearing housing.
5. Lock out power to driver.
The impeller clearance setting procedure
must be followed. Improperly setting the
clearance or not following any of the
proper procedures can result in sparks,
unexpected heat generation and
equipment damage.
CHECK IMPELLER CLEARANCE
Prior to operating the pump, impeller clearances must
be checked. This check will help ensure that the
pump turns freely and that it operates at optimal
efficiency for good equipment life and low energy
consumption. See Section 4, Table 3 for details.
The maximum impeller setting should not be set more
than .005 inch (0.13mm) above values in Table 3 or
significant performance degradation will result.
Also, for pumpage temperatures above 200° F (93°
C) the cold (ambient) setting must be increased per
Table 3. This is necessary to prevent the impeller
from contacting the casing due to differential
expansion from the higher operating temperatures.
See Section 5, Preventive Maintenance, for impeller
adjustment procedure.
