2.2 Check the condition of the pump
12
12
The shipping carton your pump came in is specially designed
12
around your pump during production to prevent damage. As a
12
precaution, the pump should remain in the carton until you are
ready to install it. Examine the pump for any damage that may
13
have occurred during shipping. Examine any other parts of the
13
shipment as well for any visible damage.
13
13
If the pump is supplied as a complete unit (motor attached to
pump end), the position of the coupling (that connects the pump
14
shaft to the motor shaft) is set at factory specifications. No
14
adjustment is required.
14
If the unit is supplied as a pump end only, follow the adjustment
14
procedures in section 8.12 Assembly of motor and pump end.
15
Pump without motor (CR, CRN 1s, 1, 3, 5, 10, 15 and 20 H
15
only)
16
If you purchased a pump without a motor, the shaft seal has been
16
set by the factory. Do not loosen the three set screws on the shaft
16
seal when attaching the motor.
16
Pump without motor (CR, CRN 32, 45, 64 and 90 H only)
17
If you purchased a pump without a motor, you must install the
18
shaft seal. The shaft seal is protected in its own sub boxing within
18
the pump packaging crate. Read the seal installation instructions
which are included in the pump package.
Pump without motor (all)
To protect the shaft and bearings during shipment, a shaft holder
protective device is used. This device must be removed prior to
installation of the shaft seal or motor.
