8KSB

The fan casing is made of galvanized steel sheets with additional thermal and sound-insulation layers. The

round ttings are equipped with rubber gaskets (see Fig. 2).

The fan is equipped with a bipolar asynchronous motor with an external rotor and a centrifugal impeller

with backward-curved blades. The motor is equipped with built-in thermal protection enabling its automatic

restarting. The motor utilizes ball bearings with a specially selected lubricant which drastically reduce the fan

noise and ensure maintenance-free operation. To further reduce the noise resulting from the fan vibration the

motor can be mounted on rubber vibration mounts (KSB...M).

There is also a higher performance motor option (KSB…S) available for select standard sizes.

INSTALLATION AND SETUP

Duct fans are intended for installation into round air ducts. The fans are installed into air duct splits.

The casing has mounting brackets to ensure optimum placement of the fan.

In case the fan is mounted on exible joints attach the fan to the structural unit by means of supports,

suspension links or brackets.

The fan may be installed in any position in consideration of the air ow direction (as indicated by the arrow

on the fan casing).

To reduce the aerodynamic drag resulting from the air ow turbulence provide for a straight section equal

to 1 air duct diameter on the fan intake side and one equal to 3 air duct diameters on the fan exhaust side. The

said sections must be free of any lters or other devices.

Make sure to arrange unimpeded access for the fan maintenance.

Having unpacked the fan and prior to installation:

Carefully read the instructions specic to the fan installation, operation and maintenance;

Check the fan for integrity and signs of transit damage.

Follow the safety regulations during the make-ready procedures and fan operation.

The fan installation procedure is as follows:

Make sure that the motor is de-energized (see Fig. 3.1);

Apply the markings for mounting the brackets onto the structural surface (unit) (see Fig. 3.2);

Drill the holes and fasten the fan on the brackets by using appropriate fasteners (e.g. expansion

bolts) (see Fig. 3.3);

Connect the ducts to the fan (see Fig. 3.4).

CONNECTION TO POWER MAINS

THE FAN MUST BE CONNECTED TO THE POWER MAINS ONLY BY QUALIFIED PERSONS

HAVING BEEN MADE FAMILIAR WITH THE PRESENT OPERATION MANUAL. THE UNIT IS

INTENDED FOR CONNECTION TO AC MAINS SUPPLYING THE VOLTAGE COMPLIANT WITH

THE TECHNICAL SPECIFICATION CHART. CHECK THE ENTIRE POWER CORD LENGTH FOR

CHOKING. DO NOT SWITCH ON THE UNIT IF THE POWER CORD IS DAMAGED. DISCONNECT

THE FAN FROM THE POWER SUPPLY PRIOR TO ANY WORK ON THE UNIT! THE NOMINAL

ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE

WARRANTY.

The fan is intended for connection to a single-phase 230 V/50 Hz AC mains.

Depending on the conguration there are two possible options for fan connection to the power mains:

via the plugged power cord;

via the junction box.

The fan connections (cables and wires) must be durable, insulated and heat-resistant. The external lead-in

must be equipped with an automatic cutout switch built into the stationary wiring to disconnect all the power

mains phases. The external switch position must ensure free access for quick power-o of the unit.

The recommended automatic switch nominal current is 2 A for for KSB 315 and 1 A for all other modications.

The recommended minimum conductor section is 0.75 mm2. The conductor selection shall be based on the

maximum permissible wire heating depending on the wire type, its insulation, length and installation method

(i.e. overhead, in pipes or inside the walls).

The power mains connection steps are as follows:

1. Internal fan connections:

Undo the screws securing the upper casing panel (see Fig. 4.1);

Remove the upper panel (see Fig. 4.2);

Run the power supply cable through the sealed lead in the side wall; Strip the wire tips to 7 - 8 mm;

Connect the wires to the terminal block in accordance with the electrical connections diagram and

the terminal markings (see Fig. 5). To do this insert the wires into the respective terminals until the insulation

stops against the metal part and secure the wires with clamping screws;

Assemble the fan.

2. Connection via the junction box.

In case of the fan connection to the power mains via the junction box the connection diagram and the

terminal markings also apply (see Fig. 5).
