location
WARNING
Diesel motor: Environmental damage due to leaking operating fluids!
In systems with diesel motors, drops of operating fluids (motor oil, diesel fuel and
battery acid) can leak out. These operating fluids are harmful to the environment
and must not be released into the soil or waters. The installation location must be
fluid-resistant!
Set up installation location according to the specifications in EN 12845! Only install
fire-extinguishing equipment at the installation location!
ƒ
Select the site of the installation location, preferably in this order:
–
A free-standing building.
–
A building adjacent to a building with a sprinkler system. With direct access from
the outside!
–
A room located in a building with a sprinkler system. With direct access from the
outside!
ƒ
Ensure fire resistance!
–
At least: 60 min
–
Recommended: 120 min
ƒ
Directly and easily accessible from the outside at any time. Mark entrance with signs
and provide lighting.
ƒ
Ensure that only authorised personnel has access.
ƒ
Protection from rain, snow and frost.
ƒ
Ambient temperature and max. humidity:
–
System with electric motor: 4 °C...40 °C
–
System with diesel motor: 10 °C...40 °C
–
Max. humidity: 50 %
ƒ
Even installation surface. Sufficiently stable foundation.
NOTICE! The operator is responsible for the provision and suitability of the
foundation!
ƒ
To ensure that the motor is sufficiently cooled, provide external openings for air cir-
culation. Note the following positioning of the ventilation openings:
–
Supply air opening: bottom/near floor
–
Exhaust air opening: top/near ceiling
ƒ
System with diesel motor: discharge exhaust fumes to the outside!
If the supply air and exhaust air openings are on the same side, provide an exhaust
pipe above the motor.
If the supply air and exhaust air openings are installed opposite each other (cross
ventilation), the exhaust pipe can be omitted. Ensure the following minimum air flow
Q in m³/h:
–
Air-cooled motor: Q = 100 x motor power in kW
–
Water-cooled motor: Q = 50 x motor power in kW
ƒ
Provide sprinkler protection in accordance with EN 12845.
Sprinkler protection can be connected directly to the pipework on the pressure side
of the system.
ƒ
Maintain a clearance of 800 mm around the system for maintenance work.
