Maintenance Schedule; Maintenance Work; Shutdown; Temporary Shutdown - Homa Chromatic 240W Sensoflat Original Instruction Manual

• If easily inflammable dissolvers and cleaning materi-
als are used, open fire, open light as well as smoking
are prohibited.
• Ensure that the required tools and materials are read-
ily available. Tidiness and cleanness ensure safe and
proper work on the machinery. Remove used clean-
ing materials and tools from the machinery after the
work has been carried out. Keep all materials and
tools in a dedicated place.
• Service media (such as for example oils, lubricants,
etc.) must be captured in a suitable container and
must be disposed of according to the regulation
75/439/EEC and writ §5a, 5b abfG, Waste Avoidance
and Management Act). Respective protective clothing
must be worn when carrying out cleaning work and
maintenance work. This must be disposed of accord-
ing to waste catalogue TA 524 02 and EC directive
91/689/EEC. Only lubricants recommended by the
manufacturer must be used. Oils and lubricants must
not be mixed. Only use manufacturer's original parts.
A test run or function test of the machinery must only
be carried out according to the general operating con-
ditions!

6.2. Maintenance schedule

Every six months:
• Visual inspection of the power supply leads
• Visual inspection of the cable holders and the wiring
• Visual inspection of accessories, such as for example
suspension device, lifting devices, etc.

6.3. Maintenance work

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 ma-
chinery 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 con-
stant 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 dam-
age to the power cable.
The hoisting wires/cable holders (biners) and the wir-
ing must be replaced immediately if there are slight
signs of tear and wear!
Visual inspection of accessories
The accessories, such as for example suspension devic-
es, 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 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 opera-
tion. During longer shutdown periods, carry out a regular
(monthly to quarterly) function run for a period of 5 min-
utes.
Caution!
Only carry out a function run under the proper con-
ditions 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 se-
cure 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.
