DESIGN AND OPERATING PRINCIPLE

The fan casing is made of an aluminium frame fastened with aluminium corners and removable heat- and sound-insulated double-layer panels made of aluzinc.
Thanks to its corrosion-resistant aluzinc casing and heat-insulation material, the fan is suitable for outdoor installation.
The Iso-VK fan is equipped with an asynchronous motor with an external rotor and a centrifugal impeller with backward curved blades.
The fan has a special design that allows you to change the position of the side panels for air supply in directions at an angle of 90°.

When connecting the fan to the air duct system, it is recommended to use the accessories specified in the User’s manual.
Connecting spigots, which also serve as vibration damping inserts, can be of square or round cross-section.
Spigots of round cross-section are equipped with rubber seals.
Connecting spigots are not included in the delivery set, they are ordered separately.

MOUNTING AND SET-UP

BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER).
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.

Before installing the fan, make sure that there is no visible damage to the impeller and check the integrity of the insulation of the power supply wires.
The impeller must rotate freely without touching the flange and casing.
The fan must be installed in an air duct of similar diameter.
The fan must be mounted in such a way that the direction of the air flow arrow on the fan casing coincides with the direction of air in the system. The fans are installed between the air ducts.
The connection to the air ducts is carried out using an appropriately sized flexible adapter.
In case of mounting the fan on flexible joints, attach the fan to a structural unit by means of brackets.
The fan can be mounted in any position according to the direction of air flow (indicated by the arrow on the fan casing).
To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect the straight air duct section to the fan spigots on both sides of the fan. The minimum straight air duct length is  equal to 1 air duct diameter on the intake side and 3 air duct diameters on the exhaust side.
No filters or other devices must be installed in these sections.
The fan is not a ready to use unit and requires connection to the air ducts.
Install the fan securely while ensuring free access for maintenance operations, the required distance to the walls of the room is at least 1 m.
The Iso-VK fan is equipped with a drain fitting for connection to the drainage system.

Fan installation sequence:

• Before installation, route the wires and cables necessary to connect the fan to the mains.
• Make sure that the motor is not energized.
• Fasten the MH Iso-VK brackets in accordance with the supporting plane (structure).
• Fix the fan to the MH Iso-VK mounting brackets using suitable fasteners (e.g. dowels).
• Connect the air ducts to the fan.

The MH Iso-VK brackets and the RSD Iso-VK protective hood are not included in the delivery set and must be ordered separately.

CONNECTION TO POWER MAINS

DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

• The unit is rated for connection to power mains with the parameters specified in the “Technical data” section, according to the wiring diagram.
• The connection must be made using durable, insulated and heat-resistant conductors (cables, wires). The actual wire cross section selection must be based on the maximum load current, maximum conductor temperature depending  on the wire type, insulation, length and installation method.
• The unit must be connected to a stationary power supply network in accordance with the applicable regulations.

The electrical connection must be made at the terminal board of the terminal box located on the fan casing in accordance with the wiring diagram and terminal designation.
The wiring diagram label is located inside the terminal box.

Designation
L(x) – phase N – neutral QF – automatic circuit breaker PE – ground wire TK – motor thermal protection contacts

MAKE SURE THAT THE FAN IMPELLER ROTATES IN THE DIRECTION MARKED BY THE ARROW ON THE FAN CASING.
IF NECESSARY, CHANGE THE IMPELLER ROTATION DIRECTION BY ALTERING THE PHASE SEQUENCE ON THE ELECTRIC MOTOR TERMINALS.

COMMISSIONING

THE ORGANISATION RESPONSIBLE FOR THE COMMISSIONING SHALL BE RESPONSIBLE FOR PROPER MOTOR PHASING AND STARTING PATTERN SELECTION.
DURING STARTING THE IN-RUSH CURRENTS OF THE FAN MAY SEVERAL TIMES EXCEED THE RATED VALUES. SEE “ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS” IN THE “CONNECTION TO POWER MAINS” SECTION

• After fan starting make sure that the electric motor rotates properly without undue vibration and abnormal noise.
• Make sure that the fan impeller rotates in the direction marked by the arrow on the fan casing. If necessary, change the rotation direction of the impeller by reversing the phase sequence (for a three-phase motor) or by rewiring  according to the wiring diagram located inside the terminal box (for a single-phase motor).
• Make sure that the fan energy consumption complies with the value given on the equipment nameplate and check the motor for overheating.
• The phase current should be checked once the fan reaches the rated operating conditions.
• Do not switch the fan on and off several times without pauses as this may result in damage to the winding or insulation due to overheating.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION

• The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
• When carrying out fan maintenance, it is necessary to partially disassemble it in order to access contaminated parts of the fan.
• To do this, unscrew the screws, remove the cover from the casing.
• The impeller blades require thorough cleaning every 6 months.
• Use a soft, dry cloth or compressed air to remove dust.
• Carry out wet cleaning using warm water and a mild household detergent.
• Protect the electric motor against liquid ingress.
• Do not immerse the unit in water!
• Do not use aggressive solvents, sharp objects, etc. to clean the unit to prevent damage to the impeller.
