BLAUBERG Ventilatoren GmbH Company is happy to oer your attention
the sound-insulated fan BLAUBERG Iso-K.
INTRODUCTION
The present operation manual contains technical description, technical
data sheets, operation and mounting guidelines, safety precautions and
warnings for safe and correct operation of the fan.
GENERAL
The sound-insulated Iso-K fans are designed for hot and highly polluted
air extraction with the temperature up to 100 °C in high resistance condition.
The fans are used as a component of ventilation systems installed in:
- industrial kitchens;
- industrial bakeries;
- metal processing workshops (post-welding gas removal).
The fan is available for round air ducts Ø 150, 160, 200 and 315 mm.
The fan must be grounded.
The fan is 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 dier
from those ones described in this operation manual.
SAFETY RULES
The fan complies with the requirements according to the EU norms
and directives, to the relevant EU-Low Voltage Equipment Directives, EUDirectives on Electromagnetic Compatibility.
All operations related to the electrical connection of the fan, like servicing
and repair works are allowed only after the disconnection from power mains.
All mounting and servicing operations are allowed for duly qualied
electricians with valid electrical work permit for electric operations at the
units up to 1000 V after careful study of the present operation 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 servicing and repair works. Make sure the rotating parts have come to a
full stop.
Take measures to prevent contact with the fan to avoid physical damages
during the fan test and start-up.
Misuse of the product or any unauthorized modication 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. Sucient 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
dierence per living units is 4 Pa.
The transported air must not contain any dust or other solid impurities,
sticky substances or brous materials.
The fan is not designed for use in an inammable and explosive medium.
The transported medium must not have an aggressive eect on steel at
the temperature stated in the table 1 of the section “Technical data”.
The fan motor has F class winding insulation and IP 54 ingress protection
rating.
Do not close or block the intake or exhaust vent not to disturb the normal
air circulation.
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
Store the delivered fan in the manufacturer's original packing box in a dry
ventilated premise with the ambient temperature from +5°C up to + 40°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.
Transportation of the fan is allowed by any vehicle provided the fan is
transported in the original package and is protected against weather and
mechanical damages.
Use hoist machinery for handling and transportation to prevent possible
mechanical damages.
Full the requirements for transportation of the specied cargo type
during cargo-handling operations.
Do not expose the fan to extremely low or high temperatures.
MANUFACTURER'S WARRANTY

and directives, to the relevant EU-Low Voltage Equipment Directives, EUDirectives on Electromagnetic Compatibility.
The manufacturer hereby warrants normal operation of the fan over the
period of two years from the retail sale date provided observance of the
installation and operation regulations.
In case of failure due to faulty equipment during the warranty period the
consumer has the right to exchange it.
If case of no conrmation of the sale date, the warranty term shall be
calculated from the manufacturing date.
The replacement is oered by the Seller.
The MANUFACTURER shall not be liable for any damage resulting from
any misuse of or gross mechanic interference with the fan.
Full the operation manual requirements to ensure a trouble-free and
long service life of the fan.

WARNING
The fan is designed for connection to round air ducts on both sides of the
fan.
The special xing brackets in the fan casing enable selecting the most
suitable fan installation position.
If the fan is connected through the exible anti-vibration connectors the
fan must be secured to a mounting surface with supports, hanger brackets
or brackets.
The air motion direction in the system must match the pointer on the fan
casing.
Before starting mounting:
Read carefully the fan mounting, start-up, operation and servicing instructions;
Check the fan for possible transport damages.
Follow the safety regulations during the fan start-up and operations.
MOUNTING SEQUENCE
1. Cut o power supply.
Install the fan to ensure sucient and quick access for servicing and repair
operations.
The fan must be grounded.
To reduce air turbulence related pressure losses connect a straight air duct
to the fan of the length equal to min. 1 air duct diameter on the intake side
and min. 3 air duct diameter on the exhaust side.
Power is supplied either through the external terminal box.
Mounting of the fan on the wall with the KS-ISK mounting angle brackets
is shown in g. 3 (available upon separate order).
4. Install the fan on the KS-ISK mounting brackets and x it using
appropriate fasteners.
QF
2. Mark and drill the holes on the mounting surface for the fan mounting.
3. Fix the KS-ISK mounting angle brackets on a mounting bracket using
appropriate fasteners, for example, expansion anchors.
5. Install accessories, i.e. install a backdraft damper into the fan spigot.
6. Connect air ducts to the fan and x those with clamps (available upon
separate order).

mains through the automatic switch. The contact gap on all poles at least 3 mm (VDE 0700 T1 7.12.2 / EN 60335-1).
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 is rated for connection to single-phase alternating current power
mains 230 V / 50 Hz.
The recommended rated automatic switch trip current for ISO-K fans is
stated in Table 3.
The electric connections must be performed with insulated, durable and
heat-resistant conductors (cables, wires).
The recommended conductor cross section is stated in Table 3.
The wiring diagram for connection of the single-phased fans is shown in
g. 3. The wiring diagram for connection of the three-phased fans is shown
in g. 4.
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
prior to nishing mounting.
Connection to power mains of the basic fan model with a terminal box
is as follows:
1. Cut o power supply to the fan by turning the automatic switch QF to
OFF position.
2. Remove the screws that x the terminal box cover and take o the
cover.
