Remove screws holding the front bracket to the base and lift off the pump with its attachments. Note the loca-
tion of the pipe fittings and brackets prior to removing for installation on the replacement pump. If piping is
dismantled, be sure that the check valve is re-installed so that the gate swings toward the pump.

Reassembly
Reassemble in reverse order. With the rear pump bracket (100-800
HP) left in place, realignment and spacing between the pump shaft
and the motor shaft is greatly simplified.
There should be approximately 7/8” space between the two shafts.
Place the coupling insert between the coupling halves prior to reas-
sembly. Check that both shafts rotate freely.
Refer to the previous section on coupling alignment instructions.
If shims were used originally under either pump brackets or motor
feet, be sure that they are correctly re-installed.
100-800 HP: When re-installing the fan, slide the hub on the pump shaft so that it is bottomed. Tighten the set-
screw and capscrews. If the fan blades were removed from the hub, be sure that the side of the blade marked
“Blower” faces the hub when reassembling. When tightening the coupling halves or the fan hub, tighten the set-
screws against the key first, then tighten the setscrew against the shaft. Clean or remove any dust or grime from
the blades prior to re-installing.
When replacing the retainer screen (100-800 HP), a slight force may be required to push the cooling coil into
the air cylinder so that the pins may be fitted into place.
When replacing the compressor, be sure that all piping connections are tight.
If the motor was replaced or if motor leads were disconnected, be sure that pump rotation is proper before start-
ing operation. The air pump should rotate in a clockwise direction, as viewed from the drive shaft end.
Keep the motor and other components free from dust and dirt to prevent overheating and damage. Motor lubrica-
tion should follow manufacturer’s recommendations.
