5.3 Disassembly and Reassembly
Prior to Disassembling and Reassembling
Before disassembling and reassembling the pump, be sure that the
power supply (i.e. circuit breaker) is disconnected, and remove the
cable assembly from the terminal board. To prevent serious accidents,
DO NOT perform a conducting test during disassembly and
reassembly.
Be sure to perform a trial operation when starting the pump after a
reassembly. If the pump was assembled improperly, it may lead to
abnormal operation, electrical shock, or water damage.
This section explains the disassembly and reassembly processes that
are involved up to the casing (or oil casing, in the case of 7.5 kW and
11 kW [10/15 HP] models). Refer to the structural drawing for the
respective model before disassembling. Operations involving the
disassembly and reassembly of the sealing portion (i.e. mechanical
seal) and of the motor require a specialized facility including vacuum
and electrical equipment. For these operations, contact the dealer from
whom you purchased the equipment, or the Wacker sales office in your
area.
