TRANSPORTATION AND STORAGE
The mixer shall be transported and stored in a vertical
or horizontal position. Make sure that it can´t roll or fall
over.
For longer periods of storage, the mixer must be pro-
tected against moisture and heat. The propeller should
be rotated by hand occasionally to prevent the seals
from sticking together. If the mixer is stored for more
than 6 months, this rotating is mandatory.
After a long period of storage, the mixer should be
inspected before it is put into operation. Pay special
attention to the seals and the cable entry.
INSTALLATION
Safety precautions
In order to minimize the risk of accidents in connection
with the service and installation work, the following
rules should be followed:
1. Never work alone. Use a lifting harness (part No.
84 33 02), a safety line (part No. 84 33 03) and a
respirator (part No. 84 33 01), as required. Do not
ignore the risk of drowning!
2. Make sure that there is sufficient oxygen and that
there are no poisonous gases present.
3. Check the explosion risk before welding or using
electric hand tools.
4. Do not ignore health hazards. Observe strict clean-
liness.
5. Bear in mind the risk of electrical accidents.
6 Make sure that the lifting equipment is in good
condition.
7. Provide a suitable barrier around the work area, for
example a guard rail.
8. Make sure that you have a clear path of retreat!
9. Use a safety helmet, safety goggles and protective
shoes/gloves.
10. All personnel who work with sewage systems should
be vaccinated against diseases that can occur.
11. A first-aid kit must be handy.
Follow all other health and safety rules and local
codes and practices.
Handling equipment
Lifting equipment is required for handling the mixer.
The lifting device should not have a lifting capacity
which is greater than twice the weight of the mixer.
Oversized lifting equipment could cause damage if the
mixer gets stuck when being lifted.
Make sure that the lifting equipment is securely
anchored.
Ex version!
Installation of the explosion-proof
mixer must be performed by autho-
rized personnel.
In order to avoid accidents, warning
signs, for rotating propellers and ma-
chines that start automatically must
be positioned visibly. The area in the
proximinity of the machines should be fenced off.
For some installations and at certain operating
points on the performance curve the noise level
70 dB or the noise level specified for the actual
machine can be exceeded.
Always lift the machine by the lifting
device, never by the motor cable.
To reduce the risk of electric shock,
see chapter “Installation” and
“Electrical connections”.
The tank of a sewage machine sta-
tion must be vented in accordance
with local plumbing codes.
The machine is not to be installed in
locations classified as hazardous in
accordance with the national electric
code, ANSI7NFPA 70-1990.
CAUTION!
This machine is intended to run fully
submerged. Level sensing equip-
ment should be installed if there is a
possibility that the machine could be
operated at less than the “minimum
submergence depth” see chapter
“Dimensions”.
Always lift the machine by the lifting
device, never by the motor cable.
Keep out from suspended loads.
Make sure that the machine can’t
roll or fall over and injure people
or damage property.
