PREPARATION FOR START-UP
When installing in a potentially explosive
environment, ensure that the motor is properly
certified.
CHECKING ROTATION
1. Lock out power to driver. Remove coupling spacer if
installed.
1 Make sure everyone is clear. Jog driver just
long enough to determine direction of rotation. Rotation
must correspond to arrow on bearing housing.
2
Lock out power to driver before proceeding
with coupling spacer installation.
NOTE: Pump is shipped with coupling spacer
removed.
COUPLING PUMP AND DRIVER
2. Make sure coupling hub is securely fastened to the
driver shaft. (This is a good time to check pump hub
also.)
3. Unlock driver power.
The coupling used in an ATEX classified
environment must be properly certified.
1. Check the gap between the coupling hubs against
the dimensions shown on the elevation drawing or as
stamped on the coupling hub. For any necessary
adjustment, move the driver not the pump.
