Centro-MZ
BLAUBERG Company is happy to oer your attention a new high-quality
inline centrifugal Blauberg Centro-MZ fan. The solid team of high-qualied
professionals with many years of working experience, technological
innovations in design and production, high-quality components and
materials from the top worldwide producers have become the precondition
for the best fan in its class.
INTRODUCTION
The present service instruction contains technical description, technical data
sheets, operation and mounting guidelines, safety precautions and warnings
for safe and correct operation of the fan.
GENERAL
The inline centrifugal fan BLAUBERG Centro-MZ is not a ready for use
product. It is a component unit designed for integration into air conditioning
and ventilation systems.
The fan is available for round air ducts from Ø100 up to Ø315 mm.
The fan must be grounded.
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.
The fan design is regularly improved, so some models can slightly dier from
those ones described in this service instruction.
SAFETY RULES
The fan complies with the requirements according to the EU norms and
directives, to the relevant EU-Low Voltage Equipment Directives, EU-
Directives on Electromagnetic Compatibility.
All operations related to the fan electrical connections, servicing and repair
works are allowed only after the fan disconnection from power mains.
All mounting and servicing operations are allowed for duly qualied
electricians with valid electrical work permit for electric operations at the
units up to 1000 V after careful study of the present user's manual.
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 fan to power mains. The casing internals must be free of any foreign
objects which can damage the impeller blades.
Disconnect the fan from power mains prior to any operations related to the
fan servicing and repair works.
Take measures to prevent contact with the fan to avoid physical damages
during the fan step and start-up.
Misuse of the product or any unauthorized modication are not allowed.
The fan is designed for connection to ac single-phase or ac three-phase
power mains, see "Technical Data". The fan is rated for permanent operation
during non-stop power supply.
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 of fuel burning
equipment to prevent back drafting. The maximum permitted pressure
dierence per living units is 4 Pa.
The air must not contain any dust or other solid impurities, sticky substances
or brous materials.
The fan is not designed for use in an inammable and explosive medium.
The transported medium must not have an aggressive eect on steel at the
temperature stated in the table 1 of the section “Technical data”.
Do not close or block the fan intake or exhaust vent not to disturb the normal
air passage. Do not sit on the fan and do not put objects on the fan.
Follow the manual guidelines to ensure trouble-free operation and long
service life of the product.
STORAGE AND TRANSPORTATION RULES

dry ventilated premise with the ambient temperature from +5°C up to +
40°C and relative humidity less than 80% at the temperature +25°C .
Store the fan in an environment with minimized risk of mechanical damages,
temperature and humidity uctuations. Store the fan inside a room or under
a shelter.
Transport of the product is allowed by any vehicle in the manufacturer's
original packing box. Use hoist machinery for handling and transportation to
prevent possible mechanical damages of the product. Full the requirements
for transportation of the specied cargo type during cargo-handling

INSTALLATION AND CONNECTION TO POWER MAINS
Connection of the fan to power mains is allowed by a qualied electrician
only. The rated electrical parameter are stated on the rating plate.
No modications of internal connections are allowed and will result in void
warranty. Connect the fan only to power mains with valid electric standards.
The house cabling system must be equipped with an automatic switch at
the external input. Connect the fan to power mains through the automatic
switch.
The contact gap on all poles at least 3 mm. The automatic switch trip current
must be in compliance with the fan current consumption, refer Table 1.
Install the automatic switch to ensure prompt access. The fan wiring diagram
is shown in g. 17-18.
Cut power supply to the fan o by turning the automatic electric switch QF
to OFF position. Take steps to prevent activation of the automatic switch.
Connection sequence of the fan basic model, without power supply cable,
g. 12-16:
1. Remove the screws that x the terminal box and take o the cover.
2. Remove the screws of the cable clamp and remove the cable clamp.
3. Route the electric cable to the terminal box through the electric lead-in
and x the cable with the cable clamp and screws.
4. Connect the cable wires to the input terminal box in compliance with the
wiring diagram, g. 17-18.
5. Re-install the terminal box cover and x it with screws.
6. Turn the fan on by turning the automatic switch QF to ON position.
MOUNTING AND OPERATION GUIDELINES
The air motion direction in the system must match the pointer on the fan
casing.
Install the fan to ensure sucient and quick access for servicing and repair

The reference cable cross section is 0.75 mm2. For the
cable selection please consider the maximum cable
temperature depending on the wire and insulation type,
the maximum current, the cable length and its layout type.
Connect the fan to power mains through the terminal block
located in the terminal box on the fan casing, following
the wiring diagram and the terminal designation.
The rating plate with terminal designation is placed inside
of the terminal block.

Regular technical supervision and maintenance of the fan are required to
ensure the product long service life and non-stop operation.
Disconnect the fan from power mains prior to any maintenance operations,
g. 18.
Maintenance of the fan is required and means cleaning the fan surfaces from
dust and dirt. Maintenance includes regular cleaning, control of the clearance
between the impeller and the casing, control of the impeller, motor, impeller
blades and grounding.
Mounting sequence of the fan:
1. Cut power supply o, g. 18;
2. Remove the air ducts from the fan, g. 19;
3. Clean the fan surfaces with a soft cloth or a brush, wetted in a mild soap
solution. Then wipe the surfaces dry, g. 20.
4. Connect the air ducts to the fans.
5. Cut power supply on.
Clean the impeller blades with a soft cloth or a brush wetted in a mild soap
solution. Avoid liquid splashing on the motor. Clean the impeller blades
thoroughly at least once in 6 months, g. 21.
Operation recommendations:
1. Clean the fan regularly from dust, dirt and foreign objects.
2. Check all fastening connections periodically.
3. Control generated noise and vibration. High vibration may indicate the
bearing wear, sticking of the dirt particles contained in the transported air,
the impeller blades wear, loose connection between the fan and the air duct.
4. Check periodically the fastening connections, impeller for possible blade
damages, check connection of the fan to the air duct and coating.
