Shutdown; Temporary Shutdown; Final Shutdown / Storage; Restarting After An Extended Period Of Storage - Homa C237 WF3 Original Instruction Manual

Visual inspection of the power supply leads
The power inlet leads must be inspected for bubbles, cracks, scratches, scour marks and/or crushing zones. If
damages are detected, the damaged power inlet lead must be replaced immediately.
The leads may only be replaced by the manufacturer or an authorized/certified service workshop. The
machinery must only be started after appropriate repair of the damage!
Visual inspection of the cable holders (biners) and the wiring (traction cable)
If the machine is used in basins/shafts the hoisting wires/cable holders (biners) and the wiring are subject to
constant wear and tear. Regular inspections are required to prevent a complete wear and tear of the hoisting
wires/cable holders (biners) and/or wiring and a complete damage to the power cable.
The hoisting wires/cable holders (biners) and the wiring must be replaced immediately if there are slight
signs of tear and wear!
Visual inspection of accessories
The accessories, such as for example suspension devices, lifting devices, etc. must be checked for correct fitting.
Loose or defective accessories must be repaired/replaced immediately.

7. Shutdown

7.1 Temporary shutdown

For this type of shutdown, the machine remains installed and is not cut off from the electricity supply. For
temporary shutdown, the machine must remain completely submerged so that it is protected from frost and ice.
Make sure the operating room and the pumped fluid cannot be covered by ice.
This ensures that the machine is always ready for operation. During longer shutdown periods, carry out a regular
(monthly to quarterly) function run for a period of 5 minutes.
Caution!
Only carry out a function run under the proper conditions of operation and use (see "Product
Description"). Never run the machine dry. This can result in irreparable damage!

7.2 Final shutdown / storage

Switch off the system, disconnect the machine from the electricity supply and dismantle and store it. Note the
following information concerning storage:
Beware of hot parts!
When removing the machine, be careful of the temperature of the housing components. These can heat
up to well above 40°C. Let the machine cool down to ambient temperature before you touch it.

Clean the machine.

Store it in a clean, dry place, protect the machine against frost.

Place it down vertically onto a firm foundation and secure it against falling.

Seal the intake and discharge ports of pumps with suitable material (such as foil).

Support the electric connecting lead on the cable lead-in to help avoid a permanent deformation.

Protect the ends of the electric power cable from moisture.

Protect the machine from direct sunshine as a preventive measure against brittleness in elastomer
parts and the propeller and casing coating.

When storing the machine in a garage please remember: Radiation and gases which occur during
electric welding destroy the elastomers of the seals.

During lengthy periods of storage, regularly (for example every six months) turn the impeller or
propeller by hand. This prevents indentations in the bearings and stops the rotor from rusting up.

7.3 Restarting after an extended period of storage

Before restarting the machine, clean it of dust and oil deposits. Then carry out the necessary maintenance actions
(see "Maintenance"). Check that the mechanical shaft seal is in good order and working properly. Once this work
has been completed, the machine can be installed (see "Installation") and connected to the electricity supply by a
specialist. See "Start-up" for instructions on restarting.
Only restart the machine if it is in perfect condition and ready for operation.
