The unit is a centrifugal inline fan in a sound-insulated casing. The fan casing is made of painted sheet steel using heat- and sound-
insulation material. The round connecting spigots are rubber sealed.
The fan is equipped with a two-pole AC motor with an external rotor and an impeller with backward curved blades. The motor has an
integrated overheating protection with an automatic restart. Use of the motor with ball bearings with specially selected grease ensures
low-noise, maintenance-free operation of the fan.
The KSV fans are equipped with filters of different filtering classes. Each fan enables installing up to three filters of different intake air
filtration classes (from rough to fine filtering).
The air flow direction is indicated by the arrow on the fan casing.
The Iso KSV ES fans are equipped with an electrostatic filter that provides cleaning of air from fine dust, aerosols, smoke, soot particles and
soot. Electrostatic filters rely on gravity of oppositely charged objects. Polluted air flows through the spray charging unit where particles
become ionized. Then ionized particles are moved by the air stream and settle on the collecting plates which are oppositely charged.

The fan is suspended to the mounting surface through the threaded rod fixed inside the expansion anchor.
The fan is intended for mounting to round air ducts and is installed between them.
The casing is equipped with fixing brackets for easier installation of the fan. While installing the unit, ensure convenient access for
subsequent maintenance and repair. Fasteners for ceiling mounting are not included in the delivery set and should be ordered separately.
While choosing fasteners consider the material of the mounting surface as well as the weigh of the unit (refer to the «Technical data»
section). Fasteners for unit mounting should be selected by the service technician.

Access to filters
(only for models
with filters )
To get the best performance of the fan and to minimize turbulence-induced air pressure losses, connect the straight air duct section to
the spigots on both sides of the unit while installing.
Minimum straight air duct length:
• equal to 1 air duct diameter on the intake side
• equal to 3 air duct diameters on the outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects. To prevent uncontrollable access to
the fans, the spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.
INSTALLATION AND SETUP

10
KSV(1)
www.ventilation-system.com
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 1~230 V/50 Hz power mains.
• The unit must be connected to power mains using insulated electric 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 external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric circuit
in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown of the unit.
The trip current of the automatic circuit breaker QF must exceed the maximum current consumption of the unit (refer to the technical
data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row following the
maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
The recommended cross section of conductors (cables, wires) is 0.75 mm2.
The recommended circuit breaker nominal current should be not less than 1 A.

www.ventilation-system.com
Maintenance operations of the unit are required 3-4 times per year. They include regular cleaning of the unit and periodic cleaning of filters.
1. Filter maintenance.
Dirty filters increase air resistance in the system and reduce supply air volume.
The filters require cleaning not less than 3-4 times per year.
Vacuum cleaning is allowed.
After two consecutive cleanings filters must be replaced.
For new filters, contact the Seller.
Filter cleaning periodicity for electrostatic filters is from 7 to 21 days, determined by the user based on the results of a visual check of the filter.
To replace/clean filters, follow these steps:
1. Unlatch the service panel.
2. Open the service panel.
3. Pull the filters to remove.
4. Clean the filters with a vacuum cleaner.
5. Assemble the unit in the reverse order.
2. Fan maintenance (once a year).
Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply
air flow. Clean the fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
3. Supply air ow control (twice per year).
The supply duct grille may get clogged with leaves and other objects reducing the unit performance and supply air delivery.
Check the supply grille twice per year and clean it as required.
4. Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air ducts
which reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
