SECTION 4
MAINTENANCE
GENERAL
The electric capacity control actuator is a relatively simple mechanism with few moving parts; it therefore should provide
reliable operation for long periods with a minimum of maintenance. The signal-conditioning controllers incorporate
complicated solid-state circuitry and should not be serviced in the field. Factory service is recommended for any
inoperative controller.
Refer to Figure 6 to identify component locations and part numbers noted in the following paragraphs.
RECOMMENDED SPARE PARTS
Unscheduled parts replacement in the actuator unit due to failure or malfunction is unusual. When the pump is installed
in a process where maintenance downtime must be kept to a minimum, however, the following spare parts should be on
hand:
PART NO.
