Shutdown for maintenance work or storage

• Switch off the system and secure it against being switched on again by unauthorized
persons.
• Have a qualified electrician disconnect the pump from the mains.
• Close the slide valves in the pressure pipe after the well cover.
You can then begin disassembly.
CAUTION: beware of burns!
Housing parts may heat up to well above 40 °C
during operation. There is a risk of burns! After
switching it off, let the pump cool down to ambient
temperature.
8.2.1. Removal
In the case of vertical installation, disassembly takes place in the same way as installa-
tion:
• Disassemble the well cover.
• Dismantle the ascending pipe and unit in the reverse order to installation.
When configuring and selecting lifting equipment make sure that it is adequate to
lift the entire weight of piping, pump including connection cables and water column!
When installed horizontally the water tank / reservoir must be drained completely. The-
reafter the pump can be released from the pressure pipe and disassembled.
8.2.2. Return delivery / Storage
For shipping, the parts must be packed in tear-proof plastic bags of sufficient size in
such a manner that they are tightly sealed and leak proof. The parts may only be ship-
ped by forwarding agents who have been instructed appropriately.
