against touching is provided by fi tting a hose or
pipe line at least 1 metre long.
1.6 Discharge effect
Warning!
Very powerful blow-out effect at the outlet port.
Sucked-in objects can be fl ung out at high speed
(risk of injury!).
The blowers are suitable solely for moving clean
air. To reliably prevent foreign bodies or contami-
nants being sucked in and then blown out, they
must be fi ltered out before entering the blower.
Do not reach into the air outlet port!
1.7 Safety advice on cleaning and maintenance
Warning!
Cleaning and maintenance or repair work must
only be carried out after the impeller is at a
standstill. Electrical On/Off switches must be of
the lockable type or disposed so as to prevent
unauthorised switch-on whilst cleaning or repair
work is being carried out.
The impeller must be at a standstill before the
unit is opened. During cleaning and maintenance
or repair work, the unit must reliably stay isolated
from the power and secured against restarting/
unintentional start-up.
1.8 Temperature
Warning!
During blower operation, the housing takes on
the temperature of the medium conveyed. If this
exceeds +50°C, the owner must provide safe-
guards to prevent it being touched directly.
(Risk of burns!)
1.9 Motor circuit breaker
The drive motor must be protected by a motor circuit breaker
before the blower is put into service (not applicable for units
powered by frequency converter). With units powered by
frequency converter, the existing temperature sensor (PTC
thermistor detector) or temperature monitor (break contact)
is to be connected to the converter and evaluated.
1.10 Noise development
The noise radiated by the blower is not constant over the
entire range of output. Please refer to the table on page 16
for the radiated noise level.
Sound insulation is required in certain unfavourable cases
(measurements by the blower's owner are recommended).
Here, the blower's owner is responsible for sound insulation,
so that the statutory maximum sound levels at workplaces in
the vicinity of the blower are not exceeded.
Sound insulation of any kind must on no account lead to a
non-permissible increase in the ambient temperature above
max. +60°C at the drive motor.
Operating and assembly instructions SVD
1.11 Electrical hazards
Before any electrical work, the unit must always be isolated
from the power and secured against being switched on and
started up. The absence of voltage must be checked.
1.12 Speeds
Warning!
The maximum speed stamped on the motor rating
plate must never be exceeded in order to prevent
personal injury. The blower is at risk of mechani-
cal damage if the speed is exceeded.
This can cause serious injury or death!
Each component on the blower has unique natural frequen-
cies. These can be induced by certain blower speeds, which
may result in resonance mode.
The blowers are designed in such a way that resonance does
not generally occur at a constant operating speed.
This may be induced in certain circumstances when the
speed is changed if the blower is operated on a frequency
converter. These circumstances are also infl uenced by the
customer's individual installation situation or ventilation con-
nection.
These natural frequencies must be excluded by parametris-
ing the frequency converter accordingly should they be pre-
sent within the speed range of the blower.
2 INFORMATION ON TRANSPORT,
HANDLNG AND STORAGE OF THE
MACHINE
2.1 Transportation and handling
• Before assembling and putting into service, check all parts
for damage during transportation. A blower that is damaged
can present an increased risk to safety and therefore should
not be put into service.
• Do not store the blower unprotected outdoors
(protect against humidity).
• Attach lifting tackle securely. Use only lifting tackle and
load suspension devices which have an adequate load
rating. Make sure transport routes are safe.
2.2 Storage
• Ensure that the air intake connection and pressure connec-
tion are closed.
• Store the blower
-> in its original packaging if possible
-> in a closed room
-> in a dry, dust-free and vibration-free area.
• Storage temperature range from -20°C to +60°C
• After a storage period of 6 months, the blower bearings
and/or motor bearings should be checked before they are
mounted in the blower.
3 INFORMATION ON PUTTING INTO
SERVICE
3.1 Installation and assembly
• Protect the blower from the weather and install it in a hori-
zontal position, see also 1.1. For outdoor use, protection
from the weather must generally be provided that fulfi ls
the requirements listed in 1.1 Intended Use and protects
the blower from the infl uences of the weather.
