BLAUBERG Ventilatoren GmbH is happy to oer your attention the
exhaust centrifugal fan Box-D.
INTRODUCTION
The present operation manual contains a technical description, technical
data sheets, operation and mounting guidelines, safety precautions and
warnings for safe and correct operation of the fan.
Read carefully and understand the operation manual, especially the safety
requirements, before the appliance mounting and start up.
Keep the operation manual available as long as you use the appliance.
GENERAL
The exhaust centrifugal fan Box-D is designed for exhaust ventilation of
various premises, heated in winter.
The fans are not a ready to use product but a component part of a
ventilation network. The fans are designed for ceiling mounting and for
connection to Ø 100 or 200 mm air ducts, depending on the model.
The fans are allowed for operation only after nal mounting that includes
installation of protecting devices in compliance with DIN EN ISO 13875 (DIN
EN ISO 12100) as well as other construction safety equipment.
Design of the fans is regularly improved, so some models can slightly
dier from those ones described in this operation manual.

All operations related to the appliance electrical connections, servicing and
repair works are allowed only after the appliance disconnection from power
mains.
The unit is rated as a Class I electrical appliance.
All mounting and servicing operations are allowed by duly qualied
personnel.
Please follow the safety regulations and working instructions (DIN EN 50
110, IEC 364).
Make sure the impeller and the casing are not damaged before connecting
the appliance to power mains. The casing internals must be free of any
foreign objects which can damage the impeller blades or the motor.

with the "Technical Data" section.
The appliance is rated for permanent operation.
Take steps to prevent ingress of smoke, carbon monoxide and other
combustion products into the room through open chimney ues or other
re-protection devices. Sucient air supply must be provided for proper
combustion and exhaust of gases through the chimney or fuel burning
equipment to prevent back drafting. The maximum permitted pressure
dierence per living appliances is 4 Pa.
The transported air must not contain any dust or other solid impurities, as
well as sticky substances and brous materials.
The appliance is not rated for operation in a ammable or explosive
medium.
Full the operation manual requirements to ensure a trouble-free and long
service life of the appliance.

possible mechanical damages of the appliance. Full the requirements for
transportation of the specied cargo type during cargo-handling operations.
Store the appliance in a dry and cool place in the original packing.
The storage environment must not be subjected to any aggressive and/
or chemical evaporations, admixtures, foreign objects that may provoke
corrosion and damage connection tightness.
Store the appliance in an environment with minimized risk of mechanical
damages, temperature and humidity uctuations.
