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

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 tempo-
rary shutdown, the machine must remain completely sub-
merged 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. 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 fol-
lowing information concerning storage:
Beware of hot parts!
When removing the machine, be careful of the tem-
perature 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 pre-
ventive measure against brittleness in elastomer
parts and the propeller and casing coating.
• When storing the machine in a garage please remem-
ber: Radiation and gases which occur during electric
welding destroy the elastomers of the seals.
• During lengthy periods of storage, regularly (for ex-
ample 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 de-
posits. 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.

8. Troubleshooting

In order to prevent damage or serious injury while rec-
tifying machine faults, the following points must be ob-
served:
• Only attempt to rectify a fault if you have qualified
personnel. This means each job must be carried out
by trained specialist personnel, for example electrical
work must be performed by a trained electrician.
• Always secure the machine against an accidental
restart by disconnecting it from the electric system.
Take appropriate safety precautions.
• Independent work on the machine is at one's own
risk and releases the manufacturer from any warranty
obligation.
