Operating and assembly instructions A-HP
Note!
The eye bolt on the motor must not be used to lift
the entire blower. This is used if the motor needs
to be (dis-)assembled.

Note!
On devices with in-built frequency converters
(FUK devices):
The frequency converter must never be used to
lift the device or as a climbing aid!
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.
• Devices may be stored for a maximum of 2 years.
3 INFORMATION ON COMMISSIONING
THE MACHINE
3.1 Installation and assembly
• Protect the blower from the weather and install it in a
horizontal position, see also 1.1. For outdoor use, protec-
tion 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.
• Do not subject the blower subsequently to vibration or
impact loads during operation. Permissible vibrational load
on blower: refer to ISO 14694, BV-3.

• The accompanying rubber pads must always be used.
• Do not subject the pads to shearing stresses or tensile forces
• Standard blowers with base:
Bolt securely to a level and fi rm surface at the place of
use, making sure that the surface has adequate load-
bearing capacity and avoiding vibration transmission or
vibrational load.
• Standard blowers without base / console:
At the place of use, bolt the blower securely to a fi xed
base having suffi cient load capacity without transmitting
vibrations or vibrational load.
For A-HP fans with connections on the pressure and/or
suction sides, this is not possible for the following devices:
A-HP 305/30, A-HP 330/33, A-HP 355/35, A-HP 415/35
• The installation of series fans with a vertical drive shaft is
not possible with A-HP fans for the following devices:
A-HP 305/30, A-HP 330/33, A-HP 355/35, A-HP 415/35
• Wall mounting and ceiling installation is not possible for
the following devices:
A-HP 305/30, A-HP 330/33, A-HP 355/35, A-HP 415/35
• Other standards and regulations must be observed
depending on the application.
• Blower feet and consoles must be designed only for the
respective blower's own weight.
• Cover the open air intake and discharge with protective
grilles according to DIN EN ISO 13857.
• Ensure that the motor has adequate ventilation. Ambient
temperature -20°C to +60°C
• The drive motor ventilation system must not be aff ected by
the installation situation.

3.2 Electrical connection
Note!
The work described in this section may only be
performed by a qualifi ed electrician. Connect the
appliance as per the circuit diagram in the termi-
nal box and in accordance with the relevant local
requirements.
For devices operated with a frequency converter, the temper-
ature sensor (PTC thermistor) or temperature monitor (break
contact) must be connected to the converter and inspected.
• Check that the mains voltage matches the ratings on the
nameplate.
• The safety earth terminal can be found in the terminal box.
Note!
The following information should also be ob-
served when operating the drive motor with a
frequency converter:
