DANGER
Electric voltage
Risk of electric shock
a) Disconnect the unit from the mains when performing
any maintenance.
b) Secure the equipment from accidental restarting.
c) The unit may only be maintained and opened by instruc-
ted, competent personnel.
DANGER
Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
CAUTION
Hot surface
Burning hazard
Let the device cool down before maintaining.
CAUTION
High pressure
Hazard of injury due to flung off parts or oil, environmental
hazard due to oil.
a) Before starting any maintenance or repair to the oil cir-
cuit, make sure that the device is depressurized. This ap-
plies to the threaded plugs as well.
b) Avoid environmental pollution (oil spills) during cleaning
or maintenance of the oil circuit.
c) Use drip pans.
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative. Ensure secure fastening and mooring.
Air coolers have M10 eye bolts at the top of the cooler housing
for transport. Please note, due to the variety of versions the
mounting bracket is not located at the exact centre of gravity
and the cooler may swing when hoisted. Never hoist the com-
plete cooler by the M8 threads in the cooling elements!
Only use the motor transport eyes to hoist the motor without
add-ons.
Do not use the eye bolts according to DIN 580 in ambient tem-
peratures below -20 °C. The eye bolts could fracture in these
temperatures, injuring personnel and/or damage the system.
Do not strain the eye bolts more than 45° in the thread direc-
tion.
When not in use, the equipment must be protected from
moisture and heat. It must be stored in a covered, dry, dust-
free room at room temperature.
